2 Setup

2.5 Wire Your System

Typical input and output wiring is shown in Figure 2.11.

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

OUTPUTS: Maintain proper polarity (+/–) on amplifier output connec- tors.

Connect the Amplifier Output screw terminals to loudspeakers. Use ter- minals marked COM and 25V or 70V for constant-voltage loudspeaker loads, such as the JBL Control 1ST speaker included with the 180MAx Pack. Use terminals marked 4-ohms for one 4-ohm speaker or two 8- ohm speakers in parallel. Connect 70V speakers or 4-8 ohm speakers to the 180MAx, but not both, as this would over- drive the amplifier.

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

2.6 Phantom Power

Condenser mics require phantom power to operate. If you are using a condenser microphone with the 180MAx on Input 1, turn on the Phan- tom Power Switch on the back of the mixer-amplifier. The microphone must be able to work on 15V phantom power, which the 180MAx mic input connector provides.

2.7 Link In/Out Switch

This switch (Figure 2.11) affects which signals are heard when another mixer is wired to the mixer-amplifier.

IN: Any signal applied to the AMP INPUT connector will be mixed with the input signal(s).

OUT: Only the signal from the AMP INPUT connector will appear at the amplifier output.

How to link another mixer to your mixer-amplifier:

Connect the extra mixer’s LINE OUT connector to the mixer-amplifier’s AMP INPUT connector. Set the Link switch to IN.

How to set up Music-On-Hold output:

Connect mixer-amp LINE OUT to Music-On-Hold input on telephone system interface/PBX. Set the LINK SWITCH to IN.

How to set up a processing loop:

Connect mixer-amp LINE OUT to processor input. Connect processor output to mixer-amp AMP INPUT connector. Set the Link switch to OUT.
