2.5 Wire Your System

Typical input and output wiring is shown in Figure 2.7

INPUTS: Connect microphones or balanced line-level sources to mixer-amplifier balanced inputs. Set Mic/Line switches accordingly. Connect unbalanced line-level sig- nals to RCA input connectors.

OUTPUTS: Maintain proper polarity (+/–) on output con- nectors.

For each amplifier channel, connect the Amplifier Output screw terminals to the loudspeaker loads. Use terminals marked COM and 4 OHMS for a 4-ohm loudspeaker load, or use terminals marked COM and 70V or 100V for con- stant-voltage loudspeaker loads.

Connect the COM terminal to speaker negative (–) lead; connect one of the other terminals to speaker positive (+) lead.
