WARNINGTO REDUCE THE RISK OF ELECTRIC

SHOCK, DO NOT EXPOSE THISEQUIPMENT TO RAIN OR MOISTURE!

Magnetic FieldCAUTION: Do not locate sensitive high-gain equipment such as preamplifiers or tape decks directly above or below this unit. Because this amplifier has a high power density, it has a strong magnetic field which can induce hum into unshielded devices that are located nearby. This field is strongest just above and below the unit. If an equipment rack is used, we recommend locating the amplifier(s) at the bottom of the rack and the preamplifier or other sensitive equipment at the top.

Complete protection against shorted outputs, mismatched loads, overheating and DC input/output.

Efficient heat sinks and self-contained forced air cooling system.

One year warranty and guarantee.

Precautions

Although your amplifier is protected from external faults, the following safety precautions are recommended:

1. Do not change the position of the stereo/mono mode switch unless the amplifier is first turned off.

2. There are important differences between the Stereo, Parallel and Bridge modes. Please refer to page 7 for a detailed description of the different modes and there uses.

3. Switch off the amplifier or turn down the inputs before connecting to the in/out XLR's.

4. Do not short the ground lead of an output cable to the input signal ground. This will form a ground loop and may cause oscillations.

5. Do not connect both channels positive outputs together in parallel or stereo modes. And never connect any channels positive output to chassis ground.

6. Do not operate the amplifier from AC mains in excess of 10% variation above or below the selected line voltage, and only at the specified line frequency.

Stereo, Parallel & Bridge Modes

Stereo mode

Input 1 is the input to CH1's output and input 2 is the input to CH2's output. Just like a normal stereo amp.

Bridge mode

Connect to input 1 only and use the two dedicated bridge output speakons. Minimum impedance in Bridge mode must be 4 ohms, so one 8 ohm load from each speakon. Be aware that each 8 ohm load will receive 3700 watts rms. The amplifier is mono when running in bridge mode and both CH1 and CH2 bridge output speakons output the same signal.

Parallel mode

Input 1 is linked to input 2. Connect to input 1 only, the same signal will output from both CH1 and CH2 outputs. The amplifier is mono in this mode. The same effect could be achieved by connecing to input 1 and connecting input 1's link out to input 2 with a short XLR lead.

In parallel mode CH 1's level control is used to control the level for both outputs.

Note the parallel mode on Infinite amplifers is not like the parallel mode on some amplifers that allow you to drive into very low impedances. Parallel mode on the Infinite series amps just makes both inputs receive the same signal.

LIMITED WARRANTY THE WARRANTYFor a period of one (1) years from the date of delivery to the original purchaser (as shown on the original invoice or sales receipt), Void Acoustics (hereinafter "Void") warrants to the ORIGINAL OWNER of each new Infinite Series product (provided it was purchased at an Authorised Void Dealer) that it is free of defects in materials and workmanship and that each product will meet or exceed all factory published specifications for each respective model. Void agrees to repair or replace (at its discretion) all defective parts at no charge for labour or materials; subject to following provisions:

WARRANTY VIOLATIONSVoid shall take no responsibility for repair or replacement as specified under this warranty, if the damaged product has been subject to misuse, accident, neglect or failure to comply with normal maintenance procedures; or if the serial number has been defaced, altered or removed. Nor will Void accept responsibility for, or resulting from, improper alterations or unauthorised parts or repairs. This warranty does not cover any damage to speakers or any other consequential damage resulting from breach of any written or implied warranty.

VOID WARRANTY PROVISIONSVoid will remedy any defect, regardless of the reason for failure (except as excluded ) by repair, or replacement. Void will remedy the defect and ship the product within a reasonable time after receipt of the defective product at an Void Authorised Service Centre.

TO OBTAIN WARRANTY SERVICEIn the event that a Void product requires service, the Owner must contact Void or an Authorised Void Service Centre to receive an R.A.N. (Return Authorisation Number) and instructions on how to return the product to the Void Authorised Service Centre, or to the factory. Void (or its Authorised Service Centre) will initiate corrective repairs upon receipt of the returned product. Please save the original carton and all the packing materials in case shipping is required. All products being returned to the factory or service centre for repairs must be shipped prepaid.

If the repairs made by Void or the Void Authorised Service Centre are not satisfactory, the Owner is instructed to give written notice to Void. If the defect or malfunction remains after a reasonable amount of attempts by Void to remedy the defect or malfunction, the Owner shall then have the option to elect either a refund or replacement of said Void product free of charge. The refund shall be an amount equal to but not greater than the actual purchase price, not including any taxes, interest, insurance, closing costs and other finance charges (minus reasonable depreciation on the product). If a refund is necessary, the Owner must make the defective or malfunctioning product available to Void free and clear of all liens or other restrictions.

MODIFICATIONS OF EQUIPMENTVoid reserves the right to modify or change equipment (in whole or part) at any time prior to delivery thereof, in order to include therein electrical or mechanical improvements deemed appropriate by Void, but without incurring any liability to modify or change any equipment previously delivered, or to supply new equipment in accordance with any earlier specifications.

DISCLAIMER OF CONSEQUENTIAL AND INCIDENTAL DAMAGES YOU, THE OWNER, ARE NOT ENTITLED TO RECOVER FROM VOID ANY INCIDENTAL DAMAGES RESULTING FROM ANY DEFECT IN THE VOID PRODUCT. THIS INCLUDES ANY DAMAGE TO ANOTHER PRODUCT OR PRODUCTS RESULTING FROM SUCH A DEFECT.

WARRANTY ALTERATIONSNo person has the authority to enlarge, amend, or modify this Warranty. This Warranty is not extended by the length of time which the Owner is deprived of the use of product. Repairs and replacement parts provided pursuant to the Warranty shall carry only the non-expired portion of the Warranty.
