Power Requirements
Mounting
Power consumption for your model AV2.2P 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%).
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: 1.26" (32mm)
Horizontal: 18.4" (467.36mm)
The slots in the mounting flange will accept bolt diameters up to 1/4" (6.35mm).
We recommend that you provide additional support for the amplifier, especially if road use is planned, as the
weight could bend some rack frames. This support can be provided by secure shelving, support rails or a rear
rack mounting strip to match up with the rear rack mount ears provided on your AV 2.2P amplifier.

Cooling
Input Wiring
The AV2.2P uses a convection cooling system. The cabinet is designed to it allow the heat sink surface to cool
efficiently. One rack space should be provided above and below the amplifier for maximum cooling.
An unrestricted airflow to the unit must be provided. Any restriction of the air flow will cause heat to build up within
the amplifier.
If the amplifier is to be operated in an environment where the airflow is restricted (such as in sealed racks) cooling
should be supplemented by cooling fans to evacuate the heated air and boost the flow of cool air.
Do not directly connect pin 1 on the amplifier’s input or strapping XLR to the amplifier’s chassis, speaker ground
or power ground!
.
The input to the amplifier is a balanced 3-pin configuration and requires all three pins to be connected. Only high
quality twin-core shielded cable should be used.
When wiring for a balanced source, the connector going to the input of the amplifier should be wired as follows:
Pin 1 = GROUND / SHIELD.
Pin 2 = HOT (In Phase - non inverting).
Pin 3 = COLD (Reverse Phase - inverting).
When wiring from an unbalanced source you ensure that pin 3 is connected to pin 1 (input ground), either
by linking the pins in the input connector or by the source equipment's output wiring.
