Crown 1160a Guía Del Usuario

2.5 Wire Your System
Typical input and output wiring for the 180A, 280A and 
1160A is shown in Figure 2.7. See Figure 2.8 for 660A 
wiring. 

INPUTS: Connect balanced line-level sources to amplifier 
balanced inputs. 

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.

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.
