Your Wheatstone A-7000 audio console is equipped with two"module extractor tools" which are mounted in the front panelof the console mainframe (underneath and to the right, justbehind the console’s armrest).

All modules are held into the console mainframe by two panel screws (topand bottom) which, when removed, leave specially threaded holes thataccept the two extractor tools.

To remove a module from the mainframe:

Remove the front top and bottom module mounting screws, unscrew theextractor tools from the mainframe, and screw each tool into a modulemounting hole. Use only four or five turns (do not over-insert; you maydamage the threaded mainframe hole underneath). Using the extractor toolsas handles, pull the module straight up out of the mainframe.

Installation and Power

Unpacking the ConsoleThe console is normally shipped as two packages. One contains the

console; the other contains the rackmount power supply, connecting cable,installation kit, spare parts kit and documentation. Begin by unpacking andlocating these items.

Do not connect the A-7000 console to its power supply (and do notconnect the power supply to the AC power line) until instructed to doso.

Mainframe InstallationThe console is designed for simple drop-through installation in a

countertop. Cut-out dimensions (in inches) for the various mainframetypes are shown on the chart below:

Console placement should take into consideration avoiding proximityto any electromagnetic fields, such as large power transformers, motors,and flourescent lighting fixtures.

Before proceeding with input/output connections, it will be necessaryto ground the console properly (next section).

Tie the console ground lugterminal strip to the systemearth ground. Tie every pieceof equipment in the entireaudio system to the consoleground lug terminal strip.

System GroundThe first step is to ground the console.Note that as supplied from the factory, console rackmount power

supply common, audio ground, and the A-7000 mainframe are con-nected together at the console, but are NOT connected to electricalground and the chassis of the power supply. Safety requirementsdictate that a positive connection from the console mainframe toelectrical ground be made in the completed installation. Use one of thegrounding lugs on the bottom of the mainframe to establish yoursystem ground. The grounding lug terminal strip may be found at therear of the console, along the bottom edge of the mainframe pan directlyunder the rightmost mainframe slots (to the lower left if you are lookingat the rear of the console).

The system ground serves two important purposes:(1) It provides a zero signal reference point for the entire audio system;

(2) It assures safety from electrical shock.

There exist two terms that one encounters in a discussion of ground:(A) EARTH GROUND, which is usually a heavy copper rod driven into the

soil adjacent to the building (around 6 feet down) or a connection to the copperwater pipes leading into the building. Either is acceptable (unless, of course,the water pipe is made of plastic).


page 1 – 4A-7000 / Sep 2002

(B) THE POWER COMPANY EARTH CONDUCTOR that enters the build-ing at the power line breaker box; this conductor should be (and is often by code)tied to the above-mentioned earth ground at one point. This point is the SYSTEMEARTH GROUND.

TIE THE CONSOLE GROUND LUG TERMINAL STRIP TO THESYSTEM EARTH GROUND. TIE EVERY PIECE OF EQUIPMENT INTHE ENTIRE AUDIO SYSTEM TO THE CONSOLE GROUND LUGTERMINAL STRIP. If the system earth ground point is inaccessible, tiethe console ground terminal strip to the power company earth conductorat the main breaker box (see drawing "Typical Grounding Scheme" onprevious page).

Each piece of equipment should be connected by its own ground wire(usually the round third pin on the AC cord). This means that every ACoutlet must have a separate conductor run to the console ground lugterminal strip; the outlets cannot be daisy-chained as is normally encoun-tered in commercial and residential AC systems. Any equipment notsupplied with 3-wire AC cables must have individual ground wires (16gauge or larger) connected to their chassis grounds and then run to theconsole ground lug terminal strip.

Further Grounding Details

Check all equipment to be absolutely certain that each unit is powertransformer isolated from the AC mains to prevent safety hazards.

It is assumed that in each piece of audio equipment the audio groundand the chassis are tied together at some point. Any piece of equipmentlacking a grounded chassis is likely to be prone to interference problems.

Locate all unbalanced audio equipment in the same rack if possible, tominimize chassis ground potential differences. It may also be helpful toinsulate each piece of unbalanced equipment from its mounting rails in therack by means of nylon 10-32 screws and insulating washers between railsand faceplates.

Once the system is properly grounded, proceed with the consolepower supply installation and connection (next section).

Power SuppliesThe A-7000 console is powered by a Wheatstone Model PSC-6008

rackmount power supply. This heavy duty unit occupies five 19” wide rackspaces (total height 8-3/4”). Convection cooled, it requires ample ventila-tion space above and below it. The PSC-6008 generates a lot of heat in thecourse of normal operation — do not mount heat sensitive devices in thesame rack cabinet.

If failsafe redundant sup-plies have been ordered,you will be installing twounits.


page 1 – 5A-7000 / Sep 2002

Note the power supply (supplies) should be mounted in an equipmentrack within fifteen feet of the console (but no closer than 3 feet). Avoidlocating any high gain equipment (such as phono preamps, tape recorders,etc.) too near the rackmount supplies, to avoid magnetic interference intothat equipment.

Once the supply is rackmounted, it should be connected to the consoleusing the factory supplied cable. The console’s two power supply connec-tors are located at the rear of the console, one at each end of the mainframebottom pan. If you are using two supplies (failsafe option) one supply willconnect to each console connector; otherwise only one connector will beused (it does not matter which one). Note that the power supply cable’s 10-pin female connector has to be rotated until its locating pins match the maleconnectors on the console. Do not force a connector on; it attaches easilywhen properly aligned. Connect the cable(s) first to the console, then to therear of the rackmount power supply.

Note each power supply is fitted with a 3-wire grounded AC cord thatshould be plugged into a "clean" AC power source, that is, an AC sourcethat feeds only the control room audio gear. This source should be aseparate feed from those powering lighting, air-conditioning, or any othernon-audio machinery. The third pin ground wire of the AC source shouldbe tied to the central system ground point. Note that while the AC powercord ground wire terminates at the power supply chassis, it does NOTconnect to the A-7000 console common; the console itself must begrounded separately. (See previous section,"System Ground".)

Failsafe Dual Redundant Supply

Wheatstone failsafe power supply systems use two separate rack-mount power supplies for each piece of powered equipment. Thougheither is capable of running a full load on its own, in failsafe operation bothunits run in tandem: if one fails, the other takes over, assuring uninter-rupted operation.

In order for failsafe systems to perform as designed, always haveBOTH rackmount supplies powered up and connected to their associatedequipment.

Energizing

Assuming the A-7000 console mainframe is properly placed andgrounded, and its PSC-6008 power supply (or supplies) correctlyrackmounted and connected to the console, you may now energize thePSC-6008 rackmount power supply by plugging it into the AC mains andturning it on, using its front panel circuit breaker/switch. (If you are usinga failsafe system, turn on BOTH supplies.) The five LEDs on the powersupply front panel should light up to indicate the presence of theirrespective voltages. The console's individual module switches will as-sume factory default settings.

Once you have verified proper power-up, turn off the rackmount powerOnce you have verified proper power-up, turn off the rackmount powerOnce you have verified proper power-up, turn off the rackmount powerOnce you have verified proper power-up, turn off the rackmount powerOnce you have verified proper power-up, turn off the rackmount powersupplies to de-energize the console.

The AMP tool insulation dis-placement connector system.Note the right angle hood withself-locking tabs. The tool,multipin connectors (with goldplated pins) and latchinghoods are supplied with eachconsole.

Audio and Control WiringAll audio and control I/O connections to the A-7000 console are made

through multipin connectors (DB-25 and DB-9) located on the bottom of theconsole mainframe.

The Insulation Displacement Connector System

The I/O wiring interface system is based on insulation displacementtechnology. A special AMP wiring tool is included with each console; it isauto-indexing, and allows individual wire connections to be positively madewith a single squeeze of the tool's trigger. The trigger action is ratchetcontrolled, and will not release until a full connection is made. Once released,the multipin connector held in the tool's jaw automatically indexes to the next

connector pin. The technology is such that no stripping, soldering or tinning ofwire ends is required; all that is needed is for the wires destined for theconnector be snub cut and laid out in order (although tubing should be used onbare drain wires). An empty DB-25 or DB-9 connector is inserted into the tool,indexed to the first pin, and the wires are inserted one by one into the jaw andthe trigger squeezed. In this way a single multipin connector can be completelywired up in a minute or two.

In the event of a wiring error, connector pins may easily be removed fromthe shell with the wire still attached, and inserted into the correct position.Observe the side of the connector, with the metal part down. You will see a rowof "Vees"—simply press the top of the vee together with a scribe or other sharpinstrument; this will unlock the pin from the shell, and it can be removed andinserted into the correct position. Spread the vee apart to lock the pin in the newposition. It should never be necessary to discard a connector due to a wiringerror.

Note that mating hoods for each connector are also supplied with theconsole. These have locking screws that hold the connectors securely to thebottom of the console mainframe.

Connection Procedures

As supplied from the factory, the console requires no logic connectionsto function. Therefore an orderly installation begins with the audio wiring.Note this manual is organized by module type (inputs, outputs, monitormodules, etc.); each chapter contains detailed wiring instructions for itsmodule type. Proceed through the manual, chapter by chapter, until allmodules have been wired to suit your particular installation requirements.Once proper audio operation is verified, go back to each individual chapterand proceed with control wiring.

Recommended setup is to have all microphone inputs connected to thefirst channels (mono mic type), with the remaining line input sourcesconnected to stereo line inputs. It is good practice to group input typestogether. For example, if you have three cart machines, connect them to theinputs of three successive stereo line modules.

Analog Insert Points

Certain module signals have insert patch points in their signal chainsto allow outboard audio processing. These include MONO MIC INPUTS(MM-7000) and OUTPUT MODULES (OM-7000).

Normally these points are internally bridged at the factory (via PCB-mounted programming switches) prior to shipment. If you intend to useoutboard signal loops at these points, you must reprogram these switches.See pages 2-6 (mic inputs) and 4-3 (output modules) for details.

Unbalanced Connections

INPUTS — Wire to the console with typical shielded two conductorcable (like Belden 9451), just as if you were connecting a balanced source.At the unbalanced source machine’s output, connect the black wire (LOW)to the shield. If the machine has a -10 dBu output, don’t hesitate to turnmodule input gain as high as is needed.

OUTPUTS — A-7000 consoles use a balanced output circuit whichbehaves exactly like the secondary of a high-quality transformer, with nocenter tap—this output is both balanced and floating. Either the HIGH orLOW side of the output should be strapped to ground, with the output takenfrom the other side. (Normally you’d strap LOW to ground, and take HIGHto feed your unbalanced equipment.)

See Appendix for a dis-cussion of balanced ver-sus unbalanced connec-tions.

Wiring Procedure - Double Connection to One Pinref: DB-25 male multi-pin connector

Most audio equipment machine interfaces (as well as Wheatstone consoles) usesubminiature D-type connectors. Sometimes the interfaces require making two connec-tions to a single DB pin. If the wiring has been set up using punchblocks, this is not aproblem; however, for situations where direct machine-to-console wiring is used, Wheat-stone recommends the following procedure:

1) Connect the first wire to the desired pin as you normally would.2) Note connector pins may easily be removed from the DB-25 shell with the wire still

attached: Hold the connector with the metal part down and observe its side. Youwill see a row of "Vees"—simply press the top of the selected vee together with ascribe or other sharp instrument; this will unlock the pin from the shell, allowingit to be removed.

3) With the pin removed, strip out a short section of insulation from the connectedwire and wrap and solder the second wire to the first as shown above.

4) A short piece of heatshrink tubing (pictured here before being slid into place)completes the connection.

5) Re-insert the pin into the DB-25 shell, spreading the vee apart to lock it in place.

Mono Mic/Line Input Module(ML-7000)

Module OverviewIn standard configuration these modules accept mono microphone (or line

level) input signals (A or B). They are used to control level and route the sourcesignal to various console outputs and monitor busses. They are also availablewith a whole range of additional features: cue and solo functions, stereo andmono sends, and an electronically controlled multiple input switcher.

All audio and control input and output signals are made via two DB-25multi-pin connectors located in the bottom of the console’s mainframe,directly underneath each individual module; and one DB-9 connector mountedon the console’s motherboard. A pinout drawing on page 2-11 shows allwiring connections at a glance.

Controls and Functions

DUAL (A/B) – The module actually has two pairs ofinput ports: Mic A & B and Line A & B selectable via internalslide switch. Both A and B inputs have internal multiturn trimcontrols for critical gain match to specific microphones.Internal dipswitches independently select A and B phantompower for the mic inputs. Module input leads incorporate RFbeads to prevent RF infiltration.

OUTPUT ASSIGN – Assigns the module's mono signalto the console's stereo output busses: Program (PGM),Audition (AUD), Auxiliary (AUX) and Utility (UTL). If themodule's channel ON button is activated, a red "On-Air"LED indicator lights when the PGM assign button is pushed.

PGM and AUD assignments follow internal dipswitchsettings for separate SPEECH and MUSIC processing paths.This allows, via individual insert patch points at the console'soutput modules, independent processing of these two typesof signals.

AUX and UTL assignment switches may be internallydipswitch programmed to break away or follow channel on-off logic.

PAN – The panpot places the module's mono signal in theleft-right fields of assigned stereo output and monitor sig-nals. It is switchable in and out in some variations of themodule.

INSERT PATCH POINT – Each input module has itsown electronically balanced insert patch point for outboardsignal processing (may be internally dipswitch-bypassed).

DIRECT OUTPUT – Electronically balanced; for sig-nal splits or external bus-independent destinations. The di-rect output signal is taken post fader/channel on-off.

PHANTOM POWER – Internal dipswitches allow youto independently select phantom power for both A and B micinputs.

MIX-MINUS (internal) – The A-7000 console isequipped with four separate mix-minus busses, individuallyaccessible via internal dipswitch programming at each inputmodule. Each MXM bus assignment can be dipswitch-programmed for a pre or post fader/channel on-off audio tap.In addition, mix-minus can follow or break away (dipswitchprogrammable) from the channel's on-off logic.

SEND – Available as mono or dual mono. Used toprovide special effect feeds or custom monitor mixes tospecific locations. Assigns a split off the channel signal to theconsole's send busses. Send signals may be tapped pre or postfader/channel on-off (via a front panel switch) and may beturned ON or off with a second switch. An internal dipswitch

page 2 – 4A-7000 / Sep 2002


allows the send function to operate independently of themodule's channel on/off status. (NOTE that dual mono sendsnormally have two level controls; however, when the moduleis ordered with an EQ section a single dual concentric controlis used.)

IFB Bus-Minus® (Internal) – This option allows eachinput module to general an individual mix-minus output; thuseach anchor, each announcer, each host, each guest can havea dedicated mix-minus feed. Internal dipswitches determinewhether the channel signal is present or absent from the IFBfeed, and whether the signal is tapped pre or post fader/channel on-off.

CUE (and SOLO) – These monitor functions allow theconsole operator to spot check the module's signal withoutinterfering with regular bus assignments. CUE is normallysupplied; it's feed is tapped pre fader/channel on-off; SOLOis also available; it is post fader/channel on-off and moresuitable for production environments. Solo/cue signals areoutputted at the console's Control Room (CR) monitor mod-ule, where they appear at the CUE output and on the built-inmeterbridge speakers, are automatically metered on theconsole's switched VU meter pair, and can be programmed toautomatically interrupt the HEADPHONE and CONTROLROOM outputs. Exactly how the cue (or solo) signal inter-rupts the console's regular monitor output is determined byinternal dipswitch programming at the CR module itself.

Cue and Solo may be programmed at each input module(via internal dipswitches) to automatically disengage when-ever the channel ON button is pressed, preventing potentialfeedback problems within the control room itself. An op-tional bottom-of-travel fader overpress switch can also beused to place the module in CUE mode.

3-BAND EQ – This option provides three bands ofcontinuously sweepable boost and cut (±16dB; reciprocalcurves) , plus continuously sweepable frequency (40Hz–1KHz, 400Hz–8KHz, and 800Hz–16KHz). EQ in/out iselectronically switched for silent punch-ins. (NOTE: due topanel space conflicts, the EQ option is not available with dualmono send pots).

TALKBACK ASSIGN (internal) – The module signalmay be dipswitch assigned to the console's three talkbackbusses (CR to STUDIO 1 & 2, STUDIO 1 to STUDIO 2,STUDIO 2 to STUDIO 1). The talkback signal is taken prefader/channel on-off.

Talkback (TB TO CR) can be remotely activated via themodule's control ports (follows A & B source select).

page 2 – 5A-7000 / Sep 2002


FADER – Long-throw (104mm) conductive plastic. May be suppliedwith optional bottom-of-throw overpress switch.

CHANNEL ON/OFF – These switches, in addition to their primaryfunction of turning the module signal on and off, also perform numerouslogic tasks, involving MUTING (CR, studios 1 thru 4), TALLYS (on-airtally and tally 1 thru 3), and TIMER RESTART; all these can beprogrammed (via internal dipswitches) to activate when the channel ONbutton is pressed. These same switches may also be remotely operated (viathe module's control ports), permitting external ON/OFF and COUGHfunctions. Note all on/off switch logic functions follow A and B sourceselect switching. Thus each function is available at two source locations.Channel on-off switches can also control remote A & B on and off tallyindicators.

Internal Programming OptionsEach ML-7000 input module has numerous PCB-mounted slide (double

throw double pole) and dipswitches switches that may be user-pro-grammed to perform various functions. There are two main categories forthese switches: SIGNAL ROUTING (what point in the module signal patha signal is tapped from ["pre/post"] and where the signal is sent when itleaves the module ["bus assignment"]), and LOGIC FUNCTIONS (whena module's channel ON switch is pressed, many different things canhappen—both within the console itself and to external equipment con-nected to the console; what functions actually get activated are determinedby this group of switches). All switches are accessed by removingindividual modules from the console mainframe.

For programming purposes switches are described as viewed from thecomponent side of the module printed circuit board, with UP being towards themodule faceplate and RT pointing to the bottom of the module, where thechannel ON/OFF switches are located.

Mono Input Signal Routing Switches

Source Select

Two slide switches allows select mic or line input signals:SW8 – UP is Mic A input signal; DOWN is Line A input signalSW9 – UP is Mic B input signal; DOWN is Line B input signal

Music/Speech Assign (PGM & AUD)

Four switches will assign PGM & AUD to music or speech:SW18 – PGM LT (RT is speech, LT is music)SW19 – PGM RT (RT is speech, LT is music)SW20 – AUD LT (RT is speech, LT is music)SW21 – AUD RT (RT is speech, LT is music)

page 2 – 6A-7000 / Sep 2002


Insert Bypass

The slide switch SW17 allows the module's insert patch points (seeupper DB-25 input/output connector pinouts) to be internally bypassed(LT position is ON and activates the bypass; RT is OFF and places theinsert patch points into the signal path).

Mix-Minus Assign

The following four slide switches assign the module signal to theconsole's four mix-minus ACN busses:

SW22 – MXM A bus assign (UP is off, DOWN is on)SW23 – MXM B bus assign (UP is off, DOWN is on)SW24 – MXM C bus assign (UP is off, DOWN is on)SW25 – MXM D bus assign (UP is off, DOWN is on)

These four slide switches determine whether the mix-minus signal istapped before (PRE) or after (POST) the module's fader, channel on/offand panpot circuitry:

SW10 – MXM A signal tap (UP is pre, DOWN is post)SW11 – MXM B signal tap (UP is pre, DOWN is post)SW12 – MXM C signal tap (UP is pre, DOWN is post)SW13 – MXM D signal tap (UP is pre, DOWN is post)

Talkback Assign

Positions 5, 6, and 7 of a seven position dipswitch (SW6) assign themodule signal to the console's talkback busses (UP is on, DOWN is off).

SW6 Pos 5 – Talkback to Studio 1 and 2SW6 Pos 6 – Talkback Studio 1 to Studio 2SW6 Pos 7 – Talkback Studio 2 to Studio 1

IFB Assign

SW7 – Determines whether the channel signal will be present on themodule's IFB output (UP is off, DOWN is on).

SW5 – Determines whether the module's IFB signal will be tapped preor post fader/channel ON-OFF/panpot (UP is pre, DOWN is post).

Mono Input Switch Controlled Logic Functions

Auxiliary Assign

SW2 – LT: Auxiliary assign function follows channel on switch,RT: Auxiliary assign will override (activate) channel on audio FET switch(channel on tally/mute/timer functions are not activated, module is stilleffectively OFF for other bus assigns).

Utility Assign

SW3 – LT: Utility assign function follows channel on switch,RT: Utility assign will override (activate) channel on audio FET switch(channel on tally/mute/timer functions are not activated, module is stilleffectively OFF for other bus assigns).

page 2 – 7A-7000 / Sep 2002


MXM/SEND Assign

SW1 Position 4 – UP: send follows channel on switch, DOWN: sendoperates independently of channel on switch.

SW4 – LT: MXM/SEND assign function follows channel on switch,RT: MXM/SEND assign operates independently of channel on switch.

CUE and SOLO Dropout

SW1 Position 2 – UP: channel on deactivates cue function, DOWN:cue function operates independently of channel on switch.

SW1 Position 1 – UP: channel on deactivates solo function, DOWN:solo function operates independently of channel on switch.

SW1 Position 3 – UP: External source machine functions (both A andB sources) follow the optional ARM switch, DOWN: the functions workwhether ARM button is pressed or not.

Mutes

When a microphone is live in a room, that room’s monitor speakersmust be muted to prevent feedback. The A-7000 console has five mutecontrol lines: control room and studio 1-4. Each of these may be activatedby either an A or B microphone input.

SW14 Position 5 mutes the Studio 4 when mic A is liveSW14 Position 6 mutes the Studio 3 when mic A is liveSW14 Position 7 mutes the Studio 2 when mic A is liveSW15 Position 1 mutes the Studio 1 when mic A is liveSW15 Position 2 mutes Control Room when mic A is live

SW16 Position 2 mutes the Studio 4 when mic B is liveSW16 Position 3 mutes the Studio 3 when mic B is liveSW16 Position 4 mutes the Studio 2 when mic B is liveSW16 Position 5 mutes the Studio 1 when mic B is liveSW16 Position 6 mutes Control Room when mic B is live

Tally

TALLY functions (there are four) activate opto-isolated tally relayclosures at the console's control room monitor module. These closuresmay be used to control externally powered tally lights. Each of these maybe activated by either an A or B microphone input.

SW14 Position 1 activates Tally 1 when mic A is liveSW14 Position 2 activates Tally 2 when mic A is liveSW14 Position 3 activates Tally 3 when mic A is liveSW14 Position 4 activates On-Air Tally when mic A is live

SW15 Position 5 activates Tally 1 when mic B is liveSW15 Position 6 activates Tally 2 when mic B is liveSW15 Position 7 activates Tally 3 when mic B is liveSW16 Position 1 activates On-Air Tally when mic B is live

page 2 – 8A-7000 / Sep 2002


Timer Restart

When the module is turned ON the console’s digital timer can beprogrammed to automatically reset to zero and being counting up.

SW15 Position 3 activates Timer Restart when mic A is turned ONSW16 Position 7 activates Timer Restart when mic B is turned ON

Phantom Power

Positions 1 and 2 of seven-position dipswitch SW6 turn phantompower on (UP position) and off (DOWN position). Position 1 controlsmicrophone input A, and position 2 microphone B.

Hook-UpsAs stated before, all user wiring to and from ML-7000 modules is

done via two DB-25 multi-pin connectors located in the bottom of theconsole’s mainframe, directly underneath each individual module, andone DB-9 connector mounted on the console’s motherboard. A pinoutdrawing on page 2-11 shows all wiring connections at a glance.

Audio ConnectionsUpper DB-25 Connector

These include A and B mic/line inputs, and insert in and out. The micinput level is nominally -50dBu, line input and in/out insert points levelare +4dBu balanced. All signals are analog mono.

To Turn the Module ON & OFF from a Remote Location

ON SWITCH — Activates the module’s channel ON switch. Providea momentary closure between Pin 16 (A On Switch) or Pin 22 (B ONSwitch) and Digital Ground (Pins 4, 10, 17 or 23). This will latch themodule ON. (User-supplied momentary contact switch required.)

OFF SWITCH— Activates the module’s channel OFF switch. Providea momentary closure between Pin 3 (A Off Switch) or Pin 9 (B Off Switch)and Digital Ground (Pins 4, 10, 17 or 23). This will latch the module OFF.(User-supplied momentary contact switch required.)

COUGH — Temporarily Mutes the module. Provide a closure be-tween Pin 1 (A Cough) or Pin 7 (B Cough) and Digital Ground (Pins 4, 10,17 or 23). This will turn the module OFF. Note this is a non-latching mode;the module will turn ON again as soon as the closure stops. (User-suppliedmomentary contact switch required.)



page 2 – 10A-7000 / Sep 2002


Talkback to Control Room

If an ML-7000 module is being used for a studio microphone, thisconnection allows talkback from that studio to the console operator.Provide a closure between Pin 14 (A TB to CR) or Pin 20 (B TB to CR)and Digital Ground (Pins 4, 10, 17 or 23). This will cause the module’s prefader signal to be sent to the console’s Cue bus, where it may be heard bythe console operator. This non-latching condition continues until theclosure is released. (Requires user-supplied momentary actionTALKBACK switch at the studio microphone location.)

On Tally

Lets the module’s channel ON switch control an on-air light or other“microphone on” indicator at a remote location. This control functionprovides a continuous closure to ground at Pin 15 (A On Tally) or Pin 21(B ON Tally) whenever the module is ON.

This signal can be used to control an externally powered tally light thatrequires a continuous signal to function. Or an external tally light (i.e.,LED) can be powered from the input module by connecting the externalLED to +5 Digital (Pins 5 or 11) and the A or B On Tally port. In either case,current should not exceed 30 milliamps.

Off Tally

Identical to “On Tally” (preceding), only this tally is active when themodule is OFF. Off Tally A is Pin 2; Off Tally B is Pin 8.

We recommend a seriesresistor between the LEDand +5V digital when youare powering the externaltally from the console; avalue of 220Ω (1/4W 5%)is suggested.

Stereo Line Input Module(SL-7000)

Module OverviewThese are stereo input modules, designed to accept line level signals and

route them to the console's various busses. Available options are similar toML-7000 mono input modules, with additional MODE SELECTION feature,which enables the module to operate in stereo, mono, left only, or right only.

All audio and control input and output signals are made via two DB-25multi-pin connectors located in the bottom of the console’s mainframe,directly underneath each individual module; and one DB-9 connector mountedon the console’s motherboard. A pinout drawing on page 3-12 shows allwiring connections at a glance.

DUAL (A/B) – The module actually accepts two stereoline inputs: A and B. Both stereo ports have internal multiturntrim controls (left and right channels) for critical gain match-ing and L-R balance. Opto-isolated machine control portsfollow the A/B source select switches.

MODE SELECTOR – The mode button illuminates redwhen set to STEREO; four individual color-coded LEDindicators show available settings: STEREO, MONO (L+Rto both channels), LEFT to both channels, and RIGHT toboth channels. Being electronic, mode selection is losslessand click-free. When in MONO mode automatic gain com-pensation occurs to offset mono summation.

OUTPUT ASSIGN – Assigns the module's stereo signalto the console's stereo output busses: Program (PGM),Audition (AUD), Auxiliary (AUX) and Utility (UTL). If themodule's channel ON button is activated, a red "On-Air"LED indicator lights when the PGM assign button is pushed.

PGM and AUD assignments follow internal dipswitchsettings for separate SPEECH and MUSIC processing paths.This allows, via individual insert patch points at the console'soutput modules, independent processing of these two typesof signals.

AUX and UTL assignment switches may be internallydipswitch programmed to break away or follow channel on-off logic.

BALANCE – Used in conjunction with A & B input gaintrimpots, this control assures precise L-R balance of themodule's stereo signal. A center detent position nulls it out.

INSERT PATCH POINT – Each input module has itsown stereo electronically balanced insert patch point foroutboard signal processing (may be internally dipswitch-bypassed).

DIRECT OUTPUT – Electronically balanced; for sig-nal splits or external bus-independent destinations. The ste-reo direct output signal is taken post fader/balance/channelon-off.

MIX-MINUS ASSIGN (internal) – The A-7000 con-sole is equipped with four separate mix-minus busses, indi-vidually accessible via internal dipswitch programming ateach input module. Each MXM bus assignment can bedipswitch-programmed for a pre or post fader/balance/chan-nel on-off audio tap. In both cases this audio tap is a L+Rsummed version of the module's stereo signal. In addition,mix-minus can follow or break away (dipswitch program-mable) from the channel's on-off logic .

page 3 – 4A-7000 / Sep 2002


SEND – Available as mono or dual mono. Used toprovide special effect feeds or custom monitor mixes tospecific locations. Assigns a split off the channel signal to theconsole's send busses. Send signals may be tapped PRE orpost fader/balance/channel on-off (via a front panel switch)and may be turned ON or off with a second switch. Aninternal dipswitch allows the send function to operate inde-pendently of the module's channel on/off status. (NOTE thatdual mono sends normally have two level controls; however,when the module is ordered with an EQ section, a single dualconcentric control is used.) Internal dipswitching determineswhether the module's send signal is stereo or mono.

IFB Bus-Minus® – This option allows each input mod-ule to general an individual mix-minus signal. Internaldipswitches determine whether the channel signal is presentor absent from the IFB feed, and whether the signal is tappedpre or post fader/balance/channel on-off. The IFB output is asummed version of the module's stereo signal.

CUE (and SOLO) – These stereo monitor functionsallow the console operator to spot check the module's signalwithout interfering with regular bus assignments. CUE isnormally supplied; it's feed is tapped pre fader/balance/channel on-off; SOLO is also available; it is post fader/balance/channel on-off and more suitable for productionenvironments. Solo/cue signals (stereo; strappable as mono)are outputted at the console's Control Room (CR) monitormodule, where they appear at the CUE output and on thebuilt-in meterbridge speakers, are automatically metered onthe console's switched VU meter pair, and can be pro-grammed to automatically interrupt the HEADPHONE andCONTROL ROOM outputs. Exactly how the cue (or solo)signal interrupts the console's regular monitor output isdetermined by internal dipswitch programming at the CRmodule itself.

Cue and Solo may be programmed at each input module(via internal dipswitches) to automatically disengage when-ever the channel ON button is pressed, preventing potentialfeedback problems within the control room itself. An op-tional fader switch can also be used to place the module inCUE mode.

CHANNEL START/STOP SWITCHES – Theseswitches, in addition to turning the module on and off,command external source machines, and can control mutes(CR and Studio 1), the on-air tally, and timer restart. Theycontrol separate A and B opto-isolated controls ports forSTART and STOP. Dipswitch-selected logic modes areavailable for both A and B ports. START can be either pulse

page 3 – 5A-7000 / Sep 2002


or a European style latching command. SOLO and CUE functions can beprogrammed for automatic drop-out when START is pressed. The Stop(or Off) switch indicator light (solid-state) can run under local or externalcontrol, and SEND, AUX, UTL, and MXM can follow or break awayfrom START switch logic.

3-BAND STEREO EQ – This option provides three bands ofequalization, each with continuously variable boost and cut (±16dB;reciprocal curves). Center frequencies are switchable: 50/100Hz, 500/1000Hz, and 5KHz/10KHz. An EQ in/out switch activates logic con-trolled EQ punch-in and out. When equipped with EQ and SEND, themodule can still have A/B source select.

STEREO FADER – Long-throw (104mm) conductive plastic. Maybe supplied with optional bottom-of-throw overpress switch.

Internal Programming OptionsEach SL-7000 input module has numerous PCB-mounted switches

that may be user-programmed to do various things. There are two maincategories for these switches: SIGNAL ROUTING (what point in themodule signal path a signal is tapped from ["pre/post"] and where thesignal is sent when it leaves the module ["bus assignment"]), and LOGICFUNCTIONS (when a module's channel ON switch is pressed, manydifferent things can happen—both within the console itself and toexternal equipment connected to the console; what functions actually getactivated are determined by this group of switches). All switches areaccessed by removing individual modules from the console mainframe.

For programming purposes switches are described as viewed from thecomponent side of the module printed circuit board, with UP being towardsthe module faceplate and RT pointing to the bottom of the module, where thechannel ON/OFF switches are located.

Stereo Input Signal Routing Switches

Music/Speech Assign (PGM & AUD)

Four switches will assign PGM & AUD to music or speech:SW19 – PGM LT (RT is speech, LT is music)SW20 – PGM RT (RT is speech, LT is music)SW21 – AUD LT (RT is speech, LT is music)SW22 – AUD RT (RT is speech, LT is music)

Insert Bypass

The slide switch SW18 allows the module's insert patch points (seeupper DB-25 input/output connector pinouts) to be internally bypassed(LT position is ON and activates the bypass; RT is OFF and places theinsert patch points into the signal path).

page 3 – 6A-7000 / Sep 2002


Mix-Minus Assign

The following four slide switches assign the module signal to theconsole's four mix-minus ACN busses:

SW23 – MXM A bus assign (UP is off, DOWN is on)SW24 – MXM B bus assign (UP is off, DOWN is on)SW25 – MXM C bus assign (UP is off, DOWN is on)SW26 – MXM D bus assign (UP is off, DOWN is on)

These four switches determine whether the mix-minus signal is tappedbefore (PRE) or after (POST) the module's fader, channel on/off andpanpot circuitry:

SW13 – MXM A signal tap (UP is pre, DOWN is post)SW14 – MXM B signal tap (UP is pre, DOWN is post)SW15 – MXM C signal tap (UP is pre, DOWN is post)SW16 – MXM D signal tap (UP is pre, DOWN is post)

Send Mode

SW2 – When UP Send 1 is in stereo mode and receives the left channelsignal; when DOWN Send 1 is in mono mode and receives L+R sum.

SW1 – When UP Send 2 is in stereo mode and receives the rightchannel signal; when DOWN Send 2 is in mono mode and receives L+Rsum.

IFB Assign

SW12 – Determines whether the channel signal will be present on themodule's IFB output (UP is off, DOWN is on).

SW11 – Determines whether the module's IFB signal will be tappedpre or post fader/channel ON-OFF/panpot (UP is pre, DOWN is post).

Stereo Input Switch Controlled Logic Functions

Auxiliary Assign

SW4 – LT: Auxiliary assign function follows channel on switch,RT: Auxiliary assign will override (activate) channel on audio FET switch(channel on tally/mute/timer functions are not activated, module is stilleffectively OFF for other bus assigns).

Utility Assign

SW5 – LT: Utility assign function follows channel on switch,RT: Utility assign will activate channel on audio FET switch (channel ontally/mute/timer functions are not activated, module is still effectivelyOFF for other bus assigns).

Remote ON/OFF - Start/Stop Disable

SW6 - Disables the SL-7000's machine START/STOP outputs whenthis SL-7000 module is remotely turned ON or OFF.

page 3 – 7A-7000 / Sep 2002


External - Pulse/Constant

SW10 - This switch is normally not installed. May need to be installed inrare external machine control cases. Consult factory for details.

Send Assign

SW3 Position 4 – UP: send follows channel on switch, DOWN: sendoperates independently of channel on switch.

Mono Assign

SW8 – RT: MONO assign function follows channel on switch;LT: MONO assign function operates independently of channel on switch.This affects MXM post and SEND MONO post signals.

CUE and SOLO Dropout

SW3 Position 2 – UP: channel on deactivates CUE function, DOWN: cuefunction operates independently of channel on switch.

SW3 Position 1 – UP: channel on deactivates SOLO function,DOWN: solo function operates independently of channel on switch.

SW3 Position 3 – UP: external source machine ON, OFF and READYfunctions (both A and B sources) follow the optional ARM switch,DOWN: the preceding functions work whether ARM button is pressed or not.

EFS (European Fader Start)

SW7 – RT: EFS activated; channel ON switch provides latching startcontrol signal for external source machines; LT: channel ON switch providesmomentary start control pulses for external source machines.

Local Ready Function

SW9 Position 1 – A source – UP: channel off switch indicator lamp iscontrolled by console; DOWN: channel off switch indicator lamp is con-trolled by external source machine (via A READY ports on lower DB-25connector).

SW9 Position 4 – B source – UP: channel off switch indicator lamp iscontrolled by console; DOWN: channel off switch indicator lamp is con-trolled by external source machine (via B READY ports on lower DB-25connector).

SW9 Positions 2 & 3 – not used.

Mutes

Like ML-7000 inputs, SL-7000 modules can be programmed to mutestudio speakers when it’s channel ON switch is pressed. Mute functions turnof the console’s Control Room and Studio 1 monitor outputs. Each of thesemay be activated by either an A or B sources.

SW17 Position 5 mutes the Studio 1 when source A is ONSW17 Position 6 mutes the Control Room when source A is ON

page 3 – 8A-7000 / Sep 2002


SW17 Position 2 mutes the Studio 1 when source B is ONSW17 Position 3 mutes the Control Room when source B is ON

Tally

The ON-AIR TALLY function activates an opto-isolated tallyrelay closure at the console's control room monitor module. Thisclosure may be used to control an externally powered tally light.

SW17 Position 1 activates On-Air Tally.

Timer Restart

When the module is turned ON the console’s digital timer can beprogrammed to automatically reset to zero and being counting up.

SW17 Position 7 activates Timer Restart when source A isturned ONSW17 Position 4 activates Timer Restart when source B is turnedON

Hook-UpsAs stated before, all user wiring to and from SL-7000 modules is

done via two DB-25 multi-pin connectors located in the bottom of theconsole’s mainframe, directly underneath each individual module, andone DB-9 connector mounted on the console’s motherboard. A pinoutdrawing on page 3-12 shows all wiring connections at a glance.

To Turn the Module ON & OFF from a Remote Location

In the case of stereo line input modules, “remote location” can alsorefer to a remote source machine that is feeding its audio to the module inquestion. A 5VDC signal, as indicated below, will activate the module’schannel ON and OFF switches.

ON SWITCH — Activates the module’s channel ON switch. Providea momentary 5VDC signal between Pins 14 and 15 (Remote On A) or Pins20 and 21 (Remote On B). This will latch the module ON. Be sure toobserve the polarity as indicated on the pinout diagram.

OFF SWITCH — Activates the module’s channel OFF switch. Pro-vide a momentary 5VDC signal between Pins 16 and 17 (Remote Off A)or Pins 18 and 19 (Remote Off B). This will latch the module OFF. Be sureto observe the polarity as indicated on the pinout diagram.

On Tally

Lets the module’s channel ON switch control an on-air light or otherindicator at a remote location. This control function provides a continuousvoltage between Pin 12 (On Tally) and Pin 11 (Digital Common) when-ever the module is ON. When the module is ON the voltage at Pin 12 is+5VDC.

This on-tally can be used to control an externally powered tally lightthat requires a continuous closure to function, or an external tally light (i.e.,LED) can be powered from the input module by connecting the externalLED to Digital Ground (Pin 11)* and the On Tally port (Pin 12). In eithercase, current should not exceed 30 milliamps.

To START and STOP Remote Source Machines Using Module ON/OFF Switches

EXTERNAL START — Hook up the remote machine’s “start” controlpins to the SL-7000 module’s lower DB-25 connector control pins: forSTART A wire to pins 3 and 5; for START B wire to pins 8 and 6.

EXTERNAL STOP — Hook up the remote machine’s “stop” controlpins to the SL-7000 module’s lower DB-25 connector control pins: forSTOP A wire to pins 4 and 5; for STOP B wire to pins 7 and 6.

Note that these are opto isolated outputs. START/STOP COM A (pin5) and START/STOP COM B (pin 6) are the opto emitters, while theremaining connections (START A, pin 3; START B, pin 8; STOP A, pin4; STOP B, pin 7) are the opto collectors. Correct polarity must beobserved in wiring to these connections.

We recommend a seriesresistor between the LEDand +5V digital when youare powering the externaltally from the console; avalue of 220Ω (1/4W 5%)is suggested.

page 3 – 11A-7000 / Sep 2002


To Control the Module’s OFF Switch LED with an External SourceMachine

READY — Hook up the remote machine’s “ready” control pins to theSL-7000 module’s lower DB-25 connector control pins: for READY Awire to pins 1 and 2; for READY B wire to pins 9 and 10. The module’sReady ports are looking for a 5VDC signal with pin 2 positive with respectto pin 1 (READY A) and pin 9 positive with respect to pin 8 (READY B).As long as the voltage is present in the correct polarity, the OFF switch LEDwill be illuminated.

Output Module (OM-7000)

Module OverviewEach A-7000 console has two output master modules: Master A

handles Program and Auxiliary, Mix-Minus A & B, Send 1 and Mono 1;Master B handles Audition and Utility, Mix-Minus C & D, Send 2 andMono 2. All outputs are calibrated with front panel multi-turn trimpots. Inaddition, each master module has selector switches to determine whichstereo signal will be summed (L+R) for that module's Mono output (PGMor AUX, AUD or UTL).

Output masters contain both Music and Speech insert patch points forPGM and AUD stereo outputs, allowing outboard signal processing to beeasily applied to these signals. Note the insert points may be internallybypassed via PCB-mounted slide switches.

All user wiring to and from output modules is done via two multi-pinDB-25 connectors located in the bottom of the console’s mainframe,directly underneath each individual module, and one DB-9 connectormounted on the console’s motherboard. Pinout drawings on pages 4-7and 4-8 show all wiring connections at a glance.

Internal Programming OptionsEach OM-7000 output module has three slide (double throw double

pole) PCB-mounted switches that perform the following functions.For programming purposes switches are described as viewed from the

component side of the module printed circuit board, with UP being towards themodule faceplate and RT pointing to the bottom of the module, where thechannel ON/OFF switches are located.

Music Insert Bypass

When the switch SW1 is UP the bypass is activated; when DOWN themusic insert patch points are in the module's signal chain. This applies tothe PGM bus on the Master A module or the AUD bus on the Master Bmodule.

Speech Insert Bypass

When the switch SW2 is UP the bypass is activated; when DOWN thespeech insert patch points are in the module's signal chain. This appliesto the PGM bus on the Master A module or the AUD bus on the MasterB module.

Bus-Minus Assign

When the switch SW3 is DOWN the module's MXM B (Master A) orMXM D (Master B) signal is assigned to the console's Bus-Minus ACN.

Control Room Module(CR-7000)

Module OverviewThe CR-7000 module is the heart of the console's monitoring

systems. It enables the console operator to monitor all of the A-7000'soutputs: Sends 1 & 2, the four Mix-Minus feeds (A, B, C & D), Mono1 & 2, PGM, AUD, AUX and UTL, plus four external stereo line inputs.Each source has its own lighted selector switch. The selected sourcefeeds both the console's stereo CR output and the built-in headphonecircuit.

All user wiring to and from the CR-7000 module is done via two DB-25 multi-pin connectors located in the bottom of the console’s mainframe,directly underneath the module, and one DB-9 connector mounted on theconsole’s motherboard. A pinout drawing on page 5-7 shows all wiringconnections at a glance.


MODE SELECTOR – The mode button determines how each signalwill be monitored. It illuminates red when set to STEREO. Four individualcolor-coded LED indicators show available settings: STEREO, MONO(L+R to both channels), LEFT to both channels, and RIGHT to bothchannels. Being electronic, mode selection is lossless and click-free.When in MONO mode automatic gain compensation occurs to offsetmono summation.

CUE – This is the master level control for the console's CUE/SOLOsignals. Whenever a Cue or Solo button is pushed anywhere on theconsole, the resulting signal automatically interrupts the regular monitorprogram source. Exactly what form this interruption takes is program-mable via PCB-mounted dipswitches. Note Cue/Solo signals also appearat the console's built-in stereo cue speakers (mounted left and right in theVU meterbridge) via a built-in power amplifier.

HEADPHONE – The built-in headphone circuit includes an on/offswitch, a level control, high and low EQ (continuously variable, ±16dB,with EQ in/out switch) and a unique phase switch (REV), which reversesthe phase of both the left and right channels to optimize audio clarity forthe announcer's voice by putting the headphone audio in phase with hisown internal auditory path. Note that Headphone normally listens to thesame source as the control room but automatically switches to Cue or Solowhen so selected (this feature may be internally defeated by dipswitch).External headphone jacks are provided on the left and right sides of theconsole mainframe (just below counter height, to keep cords away fromthe work surface).

CONTROL ROOM – A conductive plastic level pot (with on/offswitch) controls CR monitor signals.

page 5 – 4A-7000 / Sep 2002


Internal Programming OptionsThere are five PCB-mounted programming switches on the printed circuit

board of the control room monitor module. They may be user-programmed toprovide the following functions.

For programming purposes switches are described as viewed from the compo-nent side of the module printed circuit board, with UP being towards the modulefaceplate and RT pointing to the bottom of the module, where the channel ON/OFFswitches are located.

Meter Output Module(MO-7000)

Module OverviewThe console's meter output module contains VU driver circuitry and

controls for the digital timer. On those consoles with mainframes largeenough to accommodate them (i.e., 24 inputs or more) there are dedicatedVU meter pairs for Program, Audition and Auxiliary, plus a fourthswitched pair of VUs which can pick up (via front panel selector switches)Sends 1 & 2, Mix-Minus feeds A, B, C & D, Mono 1 & 2, and Utility (plusAuxiliary on smaller mainframes).

nal line inputs may also be selected. Note Cue/Solo is automaticallymetered on the switched pair whenever activated at any point on the console(A red LED lights when in Cue/Solo metering mode).

The MO-7000 module has front panel multi-turn VU trim controls forthe console's four meter pairs: PGM, AUD, AUX, and SWITCHED.

At the bottom of the module are the timer control buttons (the timerdisplay is mounted in the righthand end of the console meterbridge):

AUTO – enables timer restart functions from programmed input modules’ ONbuttons.

S/S - START/STOP - halts the timer, holds the last count, and then restarts andaccumulates the count when depressed again.

RESET - return to zero (if the timer is stopped it will hold at zero; if it is runningit will reset to zero and immediately begin counting up).

HOLD – when held down freezes the timer display (the counter keeps on going);when released the display catches up to the current count.

All user wiring to and from the MO-7000 module takes place at thelower DB-25 multi-pin connector mounted directly beneath the module onthe console mainframe’s bottom pan. This lower connector (near theconsole armrest) inputs the module’s two external stereo line signals. Seethe pinout drawing on page 7-4.

While there are two DB-25 connectors, the upper one (towards the consolemeterbridge) is for factory use only. It sends the module’s VU to the meterbridge(a factory-provided cable runs from this upper DB-25 to a matching connectormounted at the back of the meterbridge, in the center of the console). The DB-9connector, mounted on the console’s motherboard, sends timer control signals tothe meterbridge.

Internal Programming OptionsThere are no internal programming options on the MO-7000 module.

Hook-UpsAs stated before, the only user wiring into the MO-7000 module is two

external stereo line inputs (analog +4dBu balanced) on the module’sLOWER DB-25 connector.

Superphone Input(SPN-7000; optional)

Module OverviewThe optional superphone module SPN-7000 allows complete phone seg-

ment operation directly from one module panel. It handles two callers, automaticannouncer mic functions, selection of callers feeds, caller cue and level adjust-ments, and multitrack recorder operations.

All audio and control input and output signals are connected via twoDB-25 multi-pin connectors located in the bottom of the console’s mainframe,directly underneath the module. A pinout drawing on page 8-7 shows all wiringconnections at a glance.

EXTERNAL FEEDS – These line level inputs (+4dBu) may be usedto bring in two external mono signal feeds.

RECORD READY – See "ON" switch below.MIX-MINUS CALLER FEED – These switches select which of the

console's four mix-minus busses will be used to feed the callers.FEED TRIM – Sets the level for mix-minus and external caller feeds.ASSIGN – Assigns the module signal to the console's four output

busses: PGM (program), AUD (audition), AUX (auxiliary) and UTL(utility). An On-Air LED lights whenever the module's channel ON buttonis pressed and PGM assign is activated.

CUE – PGM Cue picks up the module's pre ON/OFF signal and sendsit to the console's cue bus. Caller Cue buttons 1 & 2 (pre-fader) send callerinput to the same bus. NOTE: while both caller cue buttons may beactivated at the same time, caller cues and PGM cue are mutuallyexclusive.

CALLER INPUT – Caller 1 and 2 fader level controls.CHANNEL ON/OFF – The module's channel ON (red) and OFF

(amber) switches at the bottom of the module may be programmed tocontrol a remote reel-to-reel tape recorder (i.e., remote START/STOPfunctions). NOTE: if the RECORD READY switch at the top of thesuperphone module is activated ("Ready" LED), pressing the module'sSTART button will automatically start the reel-to-reel recording.

Internal Programming OptionsThere are 8 individual switches and one 7-position switch mounted on

the printed circuit board of the superphone module. They may be user-programmed to provide a variety of signal routing and control functions.(Individual switches are ON when the slider is positioned towards thewhite dot.)

For programming purposes switches are described as viewed from thecomponent side of the module printed circuit board, with UP being towards themodule faceplate and RT pointing to the bottom of the module, where thechannel ON/OFF switches are located.

CUE Dropout

When the dipswitch SW1 is ON, whenever the module's channel ONswitch is pressed, CUE functions will be automatically deactivated.

AUX Enable

When slide switch SW2 is OFF, AUX assign follows channel ON.When SW2 is ON, AUX assign operates independently of channel ON.

Utility Enable

When slide switch SW3 is OFF, UTL assign follows channel ON.When SW3 is ON, UTL assign operates independently of channel ON.

page 8 – 4A-7000 / Sep 2002


MICs to Assign

When slide switch SW6 is ON the module's External inputs andMix-Minus feeds are available for Cue and Output Assignment.

Output Assign

The four slide switches SW7-SW10 determine which of the console'soutput busses will be heard by callers:

SW7 activates UTL switch controlSW8 activates AUX switch controlSW9 activates AUD switch controlSW10 activates PGM switch control

Mutes

When the SPN-7000 phone channel ON switch is pressed, it can activateconsole mute functions. The first four positions of the seven-positiondipswitch SW11 determines which of console’s four mute lines will beactivated.

Position 1: CONTROL ROOM MUTE - When activated, automati-cally mutes the console's control room output whenever the module isturned ON.

Position 2: CONTROL ROOM MUTE WITH PROGRAM - Whenactivated, automatically mutes the console's control room output wheneverthe module is turned ON and the PGM ASSIGN button is activated.

Position 3: STUDIO MUTE - When activated, automatically mutes theconsole's studio output whenever the module is turned ON.

Position 4: STUDIO MUTE WITH PROGRAM - When activated,automatically mutes the console's studio output whenever the module isturned ON and the PGM ASSIGN button is activated.

On-Air Tally

When the module is turned ON, the dipswitch SW11 position 5 activatesthe on-air tally control line.

Cue Enable

Dipswitch SW11 position 6 - when activated, whenever a Caller CUEor PGM CUE switch is pressed, the caller signal will appear on the console'sCUE bus.

Timer Restart

When the module is turned ON, the console’s digital timer can beprogrammed to automatically reset to zero and begin counting up.

SW11 position 7 activates timer restart when the phone module’sON/START switch is pressed.

page 8 – 5A-7000 / Sep 2002


Hook-UpsAll audio and control input and output signals are connected via two

DB-25 multi-pin connectors located in the bottom of the console’s main-frame, directly underneath each individual module. The DB-9 connector isnot used. A pinout drawing on page 8-7 shows all wiring connections at aglance.

MeterbridgeOverview

The console’s meterbridge houses up to four pairs of left-right VU meters(Program, Audition, Auxiliary and Switched; see “Meter Output Module”Chapter 7), the digital timer display, the cue speakers, and the console clock.

The meterbridge assembly hinges open for easy access (VU meter lampreplacement, setting the clock). Simply swing the bridge up and back until itrests in a fully opened position.

Digital TimerThe console timer control buttons are located on the MO-7000 Meter

Output Module (see page 7-3).The timer is provided with an AUTO-RESTART function so programmed

input modules can automatically reset the timer display to zero and start a newcount, allowing the announcer to easily track his own pace. The AUTO buttontoggles this function on and off.

The START/STOP button halts the timer, holds the last count, and thenrestarts and accumulates the count when depressed again—perfect forcompiling tapes of desired duration.

RESET has a dual-mode capability:- if you depress it while the timer is counting, the display will instantly reset

to zero and start a fresh count;- if the timer is already stopped, depressing this button will reset the timer

to zero, where it will hold until start is pressed, or until an auto restart isactivated.

HOLD button allows you to hold the display for a longer viewing duration,while still allowing the counter to continue in the background. Releasing thebutton will then display the current count.

Console ClockThe Wheatstone digital clock is a six-digit time-of-day clock with LED

display. The clock is designed with CMOS circuits and an on-board crystal-controlled time base oscillator. There are two basic parts to the clock: a mainPCB containing the clock circuits and clock set controls (also may includecapacitor backup) and a second PCB containing displays. Clock set controlsmay be accessed by opening the meterbridge cover.

page 11 – 3


A-7000 / Sep 2002

Controls

The clock is controlled by a trimmer and two switches; the trimmer andswitches are mounted on the main clock PCB assembly.

The trimmer alters the frequency of the quartz-controlled oscillator,which in turn causes the clock to run slightly slower or faster. In order to keepaccurate time, the oscillator must run at 4.096 MHz. The oscillator is set to thisfrequency at the factory. However, due to the nature of quartz/crystal-controlled oscillators, there may be a slight change in the frequency of theoscillator during the first few months of operation due to the aging effect ofquartz crystals. A minor readjustment of the trimmer will compensate for thiseffect.

A buffered output of the oscillator is available at TP1 to assist in adjusting theoscillator.

Setting the Time

The setting controls consist of two switches: MODE and SET. To set theclock, open the meterbridge cover:

1) The control switches (mounted on the main clock PCB assembly) arelabelled "M" and "S". "M" (Mode) is used to scroll from seconds to minutesto hours; "S" is used to Set the time. The procedure is to set the clock slightlyahead of the current time, hold the second count at "00" until the current timecatches up, and then release the count.

2) Press the MODE button until the hour digits blink. Depress the SET buttonuntil the desired hour is displayed.

3) Press the MODE button until the minute digits blink. Depress the SET buttonuntil the desired minute count is displayed.

4) Press the MODE button until the second digits blink. Depress and hold theSET button; the seconds display will hold at "00". When the current timecatches up to the display, release the SET button. The clock will startcounting. Hit the MODE button three more times to place the clock intoworking mode.

Capacitor Backup

With the meterbridge open note the super capacitor at C25. This supercapacitor is self charging. Note that the super capacitor does NOT light up theclock display; it powers the clock crystal to keep it from losing count (it willdo this for about one hour).

Operational Modes

The standard factory default clock configuration is crystal-controlled, 12hour mode, stand-alone operation. However, the clock will operate eitherfrom the internal crystal controlled time base or from an ESE master (TC-76,TC-89, TC-90, autodetect) signal. Because crystal time bases are subject todrift over time, Wheatstone recommends operating the clock in the ESE slavemode for those applications where the exact time is critical. Connect an ESEmaster at connector CT3 (Pin 1 - Signal, Pin 2 - Shield). Switch #4 on SW3sets 12/24 hour mode (Off - 12 hour, On - 24 hour).

The clock can also be programmed to count in either 12 hour or 24 hourmodes, controlled by SW3 position 4.

Balanced vs. Unbalanced ConnectionsBy now everyone knows (or should know) that balanced inputs and

outputs are highly desirable - they have an intrinsic ability to reject hum,noise, crosstalk, and RF, even if the shielding and grounding leavesomething to be desired. Telephone companies routinely pack hundreds ofbalanced lines into one cable, with no shielding, next to AC power linesand street lights, and if good balance is maintained, the individual circuitsare completely free of noise and crosstalk.

Not all equipment used in stations is balanced, however, and the mostcost-effective devices often don’t have +4 dBu output levels, either.Because of these realities, all Wheatstone consoles are designed to acceptbalanced or unbalanced sources with levels as low as -10 dBu.

Connecting unbalanced inputs is simple—wire to the console withtypical shielded two conductor cable (like Belden 9451), just as if you wereconnecting a balanced source. At the unbalanced machine’s output,connect the black wire (LOW) to the shield. This “pseudo-balanced”connection has proven to be the simplest and most trouble-free way to go.Another plus is that the wiring need not be changed out if a balanced outputmachine is subsequently installed in that position. If the machine has a -10 dBu output, don’t hesitate to turn your input trimmers as high as isneeded.

A-7000 consoles use a balanced output circuit which behaves exactlylike the secondary of a high-quality transformer, with no center tap—thisoutput is both balanced and floating. Either the HIGH or LOW side of theoutput should be strapped to ground, with the output taken from the otherside. (Normally you’d strap LOW to ground, and take HIGH to feed yourunbalanced equipment.)

This type of self-compensating active-balanced output has been triedbefore, but it required costly hand-matching of resistors to maintainstability and low distortion. The 2142 balanced line driver IC uses laser-trimming of the on-chip resistors, under computer control, to achieve thedesired results. A major advantage over the discrete component designs isthe ability to replace the IC without the need for hand-picking resistors torestore the performance of the circuit. If lightning ever strikes in yourneighborhood, you know that nothing is totally immune to a close hit. It’scomforting to know that you can simply unplug the left or right Programoutput stage, and swap in another (let’s say, for example, from an Auditionoutput or a CR module control room output), and be back up and runningin minutes.

The ability to use outputHIGH or LOW permits aneasy phase reversal of theconsole's output signals,should this be desired.

Typical unbalanced input and output connections to the A-7000 console.

Notes on Level MeasurementAudio levels today are commonly referred to as voltage equivalents of

power levels in 600 ohm circuits. One milliwatt (0 dBm) in 600 ohms isa voltage of .775 V. The corresponding unit for use in circuits where theexact impedance is unknown or irrelevant is the dBu (the "u" stands for"unloaded"). Thus, 0 dBu is .775 V regardless of the impedance of thecircuit where it is measured. (Note the dBu should not be confused with thedBV; 0 dBV = 1 volt.)

For your convenience, here are some commonly encountered levelmeasurement values:

0 dBm in 600 ohms = .775 V = 0 dBu in any impedance

+4 dBu = 1.23 V

+8 dBu = 1.95 V

-10 dBu = .245 V

-20 dBu = 77.4 mV

-50 dBu = 2.45 mV

When checking out a system, remember to measure the input voltageat the connector, as variations in input impedance and generator sourceimpedance can invalidate your results.

TroubleshootingBasic Procedures

If you have encountered difficulty in testing your installation, check theitems listed below before opening the console. Note that some items mayseem very obvious; it is often the most obvious things that we overlook.

1) Are the console power supply systems properly installed and operatingcorrectly?

2) Are the sources you are using to test the console installation producingnormal, line level signals? For example, if a cart machine is the source, is thecart playing? Is the output of it connected to the console?

3) When checking for sound from the control room speakers, is theexternal monitor amplifier on? Is the amplifier volume turned up to a normallevel? Are the speakers connected to the amplifier outputs? Are the console’sSOLO and CUE functions deactivated? (Under normal programming theywill interrupt the regular monitor signal.)

4) If you have checked external devices and connections, and feel that theproblem is within the console, double check all wiring before attempting totroubleshoot the console itself.

Testing a "Live" (Powered-Up) Console – Precautions

(1) If a module must be removed, but remain connected while trouble-shooting (using the extender ribbons that come with the console), place apiece of cardboard or other non-conducting material across the consolewhere the module will be placed. This will prevent shorting, and also avoidscratching or marring the faceplates.

(2) Be extremely careful when using meter or oscilloscope test probes, toavoid shorting a test point to an adjacent connection. This is especiallyimportant when probing a pin 7 op-amp output, since the adjacent pin 8 is at18 volts.

(3) NEVER remove or insert an integrated circuit while the console ispowered up.

Integrated Circuits

The audio circuits of the console consist almost entirely of plug-in IC op-amps. The types called out in the schematic drawings and parts lists arechosen for optimum performance; in an emergency situation other types ofknown matching pinout and capability can be temporarily substituted. Someuseful troubleshooting hints for these circuits follow.

(1) Resistors and capacitors, including electrolytic capacitors, have avanishingly small failure rate in this equipment.

(2) Do not attempt to put any significance to the fact that you can measurevery low signal levels on the inverting or "minus" input of an op-amp stage.Due to the large open-loop gain of the typical op-amp, the inverting input ofan amplifier, configured as an inverter with its non-inverting input grounded,acts as a “virtual ground,” and signal levels at this point can be expected to

A P P E N D I X

A-7000 / Sep 2002 page A – 5

be extremely low. However, a circuit fault could result in a large signal levelat the inverting input, so it may be worth checking.

(3) When one of these ICs fails, it commonly swings its output to one ofthe power supply rails. This should be a first check when a bad IC issuspected. Measure the output pin of the IC directly (as opposed tomeasuring after a coupling capacitor) under a no-signal condition and lookfor a large DC offset at the output. Note that this test is not valid for thoseop-amps used in non-audio circuits such as integrators and relay drivers.

(4) The capacitive loading effect of a test probe may occasionally causeoscillations in a high gain amplifier circuit. For this reason it is advisable,when using meter probes to measure DC voltage in an amplifier circuit, toisolate the “hot” lead from the circuit under test with a 10K resistor. Thisintroduces a slight measurement error, depending on the meter inputimpedance, but this error is slight compared to the error that occurs if theamplifier is oscillating. If signal tracing with an oscilloscope, use a lowcapacity probe.

(5) Because of the feedback loop in the op-amp circuit, sometimes asignal can be measured or heard even when the IC is defective or evenremoved. Generally this signal will become more and more distorted as thelevel increases; also the gain of the affected path will be incorrect. Don’tassume that because you can observe an output signal the IC must beworking properly.

Other Details(1) In general, A-7000 consoles are rugged and user friendly. I/O

connections can be unplugged or plugged in while powered up with nodamage, provided the precautions described above concerning removal andreplacement of modules are carefully followed. Occasionally, this willcause a transient in the logic system that may be sufficient to affect achannel’s ON/OFF or CUE status, but this is rare.

(2) If the power cable is being unplugged from the mainframe or thepower supply, be sure to first turn the power off to avoid arcing theconnector pins.

(3) The module faceplate Lexan panel overlays are very durable, and canbe easily cleaned with Windex. If they should become damaged or tornthrough carelessness they can be replaced—consult Wheatstone for details.

(4) Care should be taken with the plexiglas covering the VU meters, asit is easily scratched.

(5) Fader knobs should be removed or installed only when the fader isat the end of its travel, to avoid "bowing" the internal fader structure.
