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.

For more application drawings, see the enclosed
Commercial Audio Mixer-Amplifier Quick-Start Guide.

NOTE: Crown provides a reference of wiring pin assign-
ments for commonly used connector types in the Crown
Amplifier Application Guide available at www.crownaudio.
