Crown Audio 160MA Manual De Usuario

Typical input and output wiring is shown in Figure 2.9.

INPUTS: For Input 1, connect a microphone or balanced line-level 
signal to the Input 1 balanced input. Set the Mic/Line switch (DIP 
switch #1) accordingly. For the other inputs, connect unbalanced 
line-level signals to the RCA input connectors.

OUTPUTS: Maintain proper polarity (+/–) on amplifi er output 
connectors.

Connect the Amplifi er Output screw terminals to the loudspeaker 
loads. Use terminals marked COM and 70V or 100V for constant-
voltage loudspeaker loads. Use terminals marked COM and 8 
ohms for an 8-ohm speaker.

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

Cover the output connections with the supplied clear non-touch 
cover by sliding the cover on.

Condenser mics require phantom power to operate. If you are 
using a condenser microphone on Input 1, turn on DIP switch #8 
on the back of the mixer-amp. The microphone must be able to 
work on 15V phantom power, which the mixer-amp’s mic input 
connector provides.
