Making Rear Panel Connections

When connecting the amplifier to your source equipment, match the output channel designations on the rear of your source equipment to the input jacks on the rear panel of your amplifier that have the same channel name.

Correct polarity connections are important to maintain proper speaker phasing. When making connections to the amp and speakers, adhere to a consistent pattern of using one side of the wire to the red terminals and the other side to the black terminals.

NOTE: The picture here is an AT1807 seven-channel model. Other models ranging from two to six channels will only have two to six sets of audio inputs and speaker outputs and will only hook up to two to six speakers correspondingly.

NOTE: This diagram shows the back of the amplifier, preamplifier and all speakers. Therefore, the right speakers are on the left side of the diagram, and the left speakers are on the right side of the diagram.
