Introduction 1. INTRODUCTION The AMAV AV2.2P is a 1 RU stereo power amplifier. Designed for the demanding commercial audio-visual market, the AV2.2P delivers 100 watts per channel at 4 ohms from an elegant, slim line package. The AV2.2P features front panel dual colour status LEDs, on board limiter, ground lift switch and the option of bridged operation delivering 200 watts at 8 ohms. Add to this the AV2.

They indicate three levels of operation: Below 1 watt( unlit ) 1 watt and above( green ) 1dB below actual clipping( red ) 2. Power ON indicator This LED will illuminate Blue to indicate that the amplifier is ON and is receiving the mains power. 3.

Installation 7 4. INSTALLATION Power Requirements Power consumption for your model AV2.2P amplifier is indicated on the rear panel for maximum output. Ensure that your 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 and occupies 1 EIA rack unit (1.75"/44.45mm). The rack mounting ears are packed separately with the amplifier. The mounting centres are: Vertical: 1.
Installation When wiring for an unbalanced source: Pin 1 =GROUND/SHIELD, Pin 2 = HOT (in phase with the amplifier’s output), Pin 3 = GROUND/SHIELD (joins to pin 1). NOTE: In-line XLR connectors often have a termination lug that connects directly to the chassis of the connector. Do not link this lug to pin 1 at the amplifier’s input as it will defeat the amplifier’s input grounding scheme. Output Wiring When wiring to your speakers, always use the largest gauge wire your connector will accept.
Operation 9 5. OPERATION 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 the amplifier's input.
Operation + 2.2 dBu (1.0 Volts) for rated Power into a 4 ohm load. The signal source (i.e. the equipment feeding signal to the amplifier) should have an output impedance of 600 Ohms or lower to avoid unwanted high frequency loss in the cabling. Input overload occurs at +19.10dBu (7.00 volts). Hum Problems 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.
Operation 11 NOTE If the input ground lift switch is used, you must ensure adequate shielding of the input wiring. If the signal source equipment does not provide adequate shielding (i.e. a definitive connection to ground), you must disconnect the shield from the input connector's ground pin (Pin-1) and re-connect it to the "drain" contact on the input connector. This will ensure the shield on your input wiring actually goes to the amplifier chassis and subsequently to earth.
Maintenance 6. MAINTENANCE Only competent or qualified persons should attempt any service or maintenance of the amplifier. Your AV2.2P needs minimal maintenance. No internal adjustments need to be made to the amplifier to maintain optimum performance. To provide years of reliable operation, we suggest a maintenance inspection be carried out every 12 months. Heat Sink The surface of the Heat Sink may become covered with dust over time, reducing it’s efficiency.
