AV2.2P AV2.4P PROFESSIONAL AUDIO AMPLIFIER OPERATION MANUAL AV2.2P AV2.
I M P O RTA N T SAF E TY INF ORMATION This operation manual contains important information regarding safety precautions, installation, performance, operation and maintenance of your AMAV power amplifier. You should familiarize yourself with the contents of this manual before operating your amplifier. 1. 2. Save the carton and packing material even if the equipment has 13. Do not block fan intake or exhaust ports. Do not operate equipment arrived in good condition.
INTRODUCTION AND CONTENTS Congratulations on choosing Australian Monitor for you professional amplification requirements. The AMAV stereo power amplifiers are designed for the demanding commercial audio-visual Market. Two amplifier models are available within the AMAV range. The AV2.2P delivers 100 watts per channel at 4 ohms from an elegant, 1RU slim line package. The AV2.4P delivers 200 watts per channel at 4 ohms from an elegant, 2RU package.

Figure 1 shows the panel layout of an AV2.2P. It is similar to the AV2.4P. The functions of the controls and indicators are as follows: Status Indicators for Channels A and B These are dual colour LEDs which indicate the status of the output stage.
C O N T R O L S , C O N N E C T O R S & I N D I C AT O R S 5 2 6 3 1 4 Rear Panel 1 Balanced Input (Channel-A) There is a pair of XLR connector provided for balanced signal input. A female XLR is wired in parallel with the male XLR for strapping/looping signal between amplifiers. 2 Signal GND Lift switch Pushing this switch IN disconnects signal ground from the input connectors on both channels.
I N S TA L L AT I O N Power Requirements Power consumption for your model AV2.2P / AV2.4P amplifier is indicated on the rear panel for maximum output. Ensure that mains voltage is the same as the rear panel mains voltage marker (+/- 10%). Mounting The amplifier is designed as a table top model as well as for standard 19” rack mounting. The AV2.2P occupies 1 EIA rack unit (1.75”/44.45mm). The AV2.4P occupies 2 EIA rack units (3.5”/88.9mm). The rack mounting ears are packed separately with the amplifier.
I N S TA L L AT I O N Hum Problems Signal Ground-Lift Switch Most equipment is designed for minimum hum when used under ideal conditions. When connected to other equipment, and to a safety earth in an electrically noisy environment, problems may occur. When proper system hook-up has been made, you may still have some hum or hum related noise. This may be due to any of the previously mentioned gremlins.
O P E R AT I O N IMPORTANT: All signal source equipment should be adequately earthed. This not only ensures your safety but everybody else’s as well. Faults can and do occur in mains connected equipment where the chassis can become “live” if it is not properly earthed. In these instances, the fault in a “floating” (ungrounded) piece of equipment will look for the shortest path to ground, which could possibly be your amplifier’s input.
MAINTENANCE Only competent or qualified persons should attempt any service or maintenance of your amplifier. Your AMAV amplifier will need minimal maintenance. No internal adjustments need to be made to the unit to maintain optimum performance. To provide years of unhindered operation we suggest a maintenance inspection be carried out on a regular basis, say every 12 months or so. Fuses Along with rear panel mains fuse, there are four (4) rail fuses provided internally in the unit.
