Local RCA Input and Output

Each pair of amplifier channels have their own input and output RCA connectors. The inputs are designed to
accept line level audio from a preamplifier's RCA unbalanced output connectors. Output expansion is accom-
modated with the RCA output connectors. These outputs are effectively a direct pass through from the inputs.

Amplified Output

The AV1230 connects to speakers via six plug-in Phoenix connectors. Simply unplug the connector from the
rear of the AV1230, strip the speaker wire approximately ¼" and insert the bare end into the gate on the con-
nector. Use a small flat blade screwdriver to tighten the connection to each conductor. Phoenix adapters can
accommodate up to 12 gauge speaker wire. Make sure the connector is held upside down to connect Left
and Right as shown:

Level Control

Each pair of amplifier channels have their own Local level control. It may be used to equally attenuate the
level for both amplifiers pairs.
Default from the factory, the level controls are set to full clockwise (no attenuation). Note, on the AV1230
there is a set of level controls for each pair of amplifiers (1-2, 3-4, 5-6, 7-8, 9-10, and 11-12) allowing for sep-
arate control of the left and right signals. The outer level control adjusts the volume of the right channel. The
inner level control adjusts the volume of the left channel.
