WIRING THE AA120M
Speaker Outputs - Use 2 conductor unshielded wire of the appropriate gauge. If you are unsure
about this, contact Atlas Sound Tech Support at 1-800-876-3333. Make sure you know how many
speakers you need and what tap value you intend to use.
Mic/Line Input - Use 2 conductor w/ shield for low level signals of 20-22 gauge is best. Maintain the
proper polarity, + to +, – to –, and shield to ground. For unbalanced signals, connect the (G) to the (–)
terminal.
Unbalanced Inputs and Outputs - Pre-made RCA cables can be purchased from vendors to simplify
interconnection to external devices.
Zone 2 Out - Use 2 conductor, 20-22 gauge, shielded is best. Terminate the shield at the input to the
device if possible.
