INSTALLATION GUIDELINES

1. Please read this owner’s manualcarefully before installing this ampli-fier.

2. Disconnect the battery groundterminal prior to making any elec-trical connections.

3. Check for any hazards or obstruc-tions such as gas tanks, fuel orbrake lines, and wiring harnessesbefore mounting the amplifier.

4. Pick a mounting location that willprovide adequate access and venti-lation and protect the amplifierfrom heat, moisture, and dirt.

5. Avoid sharp metal areas whenrouting cables to the amplifier, andrun RCA cables away from thepower cables and other potentiallynoisy car harnesses.

6. The amplifier should be groundedwith a short, heavy gauge wireconnected directly to the car at abare metal surface, preferablyscraped body sheet metal. Do notuse factory ground locations, seatbolts, or brackets that are spotwelded.

7. Always fuse your power connectionwithin 8 to 10 inches of the battery

terminal. Use a fuse or circuitbreaker rated slightly more than theon-board fuse(s) of theamplifier(s). The gauge of powerwire used should take into accountthe total current draw of thesystem, and the length of wireused. IASCA and other auto soundcompetition organizations havecharts available for this; you canalso find a chart in the MECP studyguide. Minimum wire gauge recom-mendations for the individual ampli-fiers are listed on the specificationpage. Always use the same gaugewire for the amplifier ground thatyou use for the power wire. Be sureto examine the battery groundcable of the vehicle, and if neces-sary, upgrade it by adding an addi-tional ground wire that is the samegauge as the amplifier’s powerwire. Remember, the amplifier canonly deliver its rated output when itis not current limited by the powerand ground supply wires.

8. This amplifier is designed to drive aspeaker load that measures from 1to 4 ohms (D600 2 to 4 ohms).Keep in mind that heat is the long-term enemy of automotive elec-


tronics and the lower your speakerload, the more heat is generated.For low impedance speaker applica-tions or restricted ventilation instal-lations, an external cooling fan maybe advisable.

9. Battery and ground connections tothe vehicle should be made withcrimped ring terminals of the appro-priate size (surface area is whatcounts); soldering the terminalsafter crimping is also recom-mended.

10. Due to the high-frequency MOSFETswitching power supply, filtering thepower cable is not generallyrequired (remember that the ampcan’t deliver full output if the powersupply is restricted). Propergrounding of the signal source ismandatory for the amplifier toreach its performance peak. If theRCA inputs are not groundedadequately via the signal source,electrical noise from the vehiclemay be picked up in the system.

NNOOTTEE:: The dual + and -- sub-out terminals of the D600/D800/D1200/D2400 are paralleled internally and the combined loadimpedance should be taken into consideration when connecting multiple subwoofers.


The Directed D1200/D2400 subwooferamplifiers have the capability ofconnecting two or more amplifiers of thesame power rating together in amaster/slave combination for increasedpower with accurate level matching. Theyare the Parallel Synced Gain and ExternalSynced Bridged combinations.

WWAARRNNIINNGG:: DO NOT attempt to combine amplifiers of differentpower ratings. These amplifier combinations workcorrectly only if the Master and Slave amplifiers areidentical models.

Parallel Synced GainIn this master/slave combination themaster amplifier pre-amp controls remainactive and the slave amplifier pre-amp isbypassed. This allows the master ampli-fier to control gain, filter, and sub-levelon both amplifiers.

This combination allows the amplifiers todrive their own separate subwoofer(s)while being synced together via an in-phase audio pre-amp signal from themaster amplifier. Wiring connections tothe amplifier subwoofer outputs in thiscombination should be standard in-phaseconfigurations, creating a parallelspeaker connection. (Refer to ParallelSynced Gain section of this guide foramplifier and speaker connectiondiagrams.)

NNOOTTEE:: One master amplifier can control up to three slaveamplifiers in this combination. Multiple identicalmaster/slave combinations can be added to anygiven system.

External Synced BridgedIn this master/slave combination themaster amplifier pre-amp controls remainactive and the slave amplifier pre-amp isbypassed. This allows the master amplifierto control gain, filter, and sub-level on bothamplifiers. This combination allows theamplifiers to drive common subwooferloads while being synced together via anout-of-phase audio pre-amp signal from themaster amplifier. In this subwoofer wiringconfiguration the master amplifier sends thepositive signal to the subwoofer while theslave amplifier sends the negative signal,making an externally bridged speakerconnection. (Refer to External SyncedBridged section of this guide for amplifierand speaker connection diagrams.)

NNOOTTEE:: Amplifiers in this combination can only be connectedin matched pairs. Multiple matched pairs may beadded to drive separate subwoofer loads in a givensystem.

Combined Amplifiers Gainand Filter Settings

NNOOTTEE:: You MMUUSSTT set the Subsonic, EQ, and other filtersettings on the master amplifier to the same posi-tions to achieve safe, optimal results. Adjustmentguidelines are discussed in the Crossover and GainAdjustment section of this guide.

MULTIPLE AMPLIFIER COMBINATIONS

The Directed D1200/D2400 subwooferamplifiers can also be used in multiplesof the master/slave combinationsallowing for unlimited expansion to asystems subwoofer section. To usemultiples of amplifier combinations thefollowing directions must be adhered tofor best results.

AAuuddiioo ssiiggnnaall - Divide the head unitor processor audio signal to themaster amplifiers by using RCA Yadapters. Be sure to divide them aneven number of times to ensure theinput level at each master amplifieris matched.

AAmmpplliiffiieerr ccoonnffiigguurraattiioonn - Set upeach master/slave amplifier combi-nation as described for the combi-nation type being used. (Refer tothe Parallel Synced Gain or theExternal Synced Bridged section ofthis guide for amplifier and speakerconnection descriptions.)


CROSSOVER SETTINGS AND GAIN ADJUSTMENT

Your Directed Audio power amplifier needs to be adjusted carefully to achievemaximum performance. These are some guidelines to follow when fine-tuning theamplifier.

Because this amplifier is only designed for subwoofer applications, the low-passcrossover is active at all times. The crossover point is adjustable to allow moreprecise system operation.

Try and keep the setting low enough to prevent image smearing (you should notbe able to hear male voices from the subwoofer) but not so low as to create a gapbetween the subwoofer and the mid-bass/midrange speakers. It will be to youradvantage to spend some extra time with this adjustment, listening to familiarmusic or system set-up discs to achieve the kind of musical reproduction that youprefer.

The gain adjustment allows you to set proper signal match for clean, quiet ampli-fier operation. Start by playing some music you are familiar with. With the gainadjustment on the amplifier in the middle of its rotation, bring up the volume onyour head unit to the 3/4 volume setting or until you start to hear distortion orclipping. If you hear distortion before you reach the 3/4 volume setting of yourhead unit, reduce the gain setting on the amplifier and start to raise the head unitvolume again. When you can listen to the music at or slightly above 3/4 on yourhead unit without audible distortion, slowly raise the gain of the amplifier untildistortion is heard, then back off the gain until the distortion is not audible. Thissetting will allow you to reach full output with all but the quietest of source mate-rial, while avoiding excessive noise in the system.

For systems using the Remote Sub Level Adjustment, increase the subwoofer gainon the amplifier by 25% and set the Remote Sub Level knob to the center positionafter making all system gain and filter adjustments. This will give the Remote SubLevel Control a wider range of adjustment to the subwoofer output.

You should take into consideration the effect that gain adjustment has on systemfrequency response and staging. Again, plan on spending some time with musicthat you know getting the gain and crossover settings the way you like. Test discsand analyzers may help with this process, but in the end it's your ears that count--listen to the music!


LED TUBE INSTALLATION (OPTIONAL)

This Directed Audio amplifier has been designed with a custom heat sink that canaccommodate two (optional—not supplied) VARAD LED tubes.

1. Before installing the LED tubes, remove and discard the mounting feet from theVARAD LED tubes.

2. Slide each LED tube assembly into your Directed Audio amplifier heat sink. Ensurethat the LEDs are facing out for optimal visibility. The wires from the LED tubeassembly should be on the signal input end of the amplifier. The Black wire fromthe LED tube is ground and the Black/White wire from the LED tube is power.

4. Run the two wires from the tube assembly and connect them to the 4-pinLED/FAN input connector. Refer to the LED/FAN harness diagram given earlier inthis manual.

NNOOTTEE:: If the optional fan IS NOT being used, it is recommended that the second LED tube be wired to this circuit. If the optionalfan is being used, it is recommended that the second LED tube be wired in parallel with the first LED tube.
