3.6 Wire Your System

CAUTION: Never change the position of 
the Mode Switch while the amplifier 
power is on. See Section 5.2.2 for more 
information.

3.6.1 Dual 8/4 Mode

Typical input and output wiring, along with level 
control and Mode Switch settings are shown in 
Figure 3.6. Make sure the Mode switch is set to 
the “Dual 8/4” position.

INPUTS: Connect input wiring for each channel.

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

Connect the Channel 1 speaker’s positive (+) 
lead to amplifier Channel 1 positive terminal; 
repeat for negative (–). Repeat each channel wir-
ing as for Channel 1. Refer to Section 3.5 for 
output connector pin assignments.

3.6.2 Dual 70V Mode

CAUTION: Never change the position of 
the Mode Switch while the amplifier 
power is on. See Section 5.2.2 for more 
information.

Typical input and output wiring, along with level 
control and Mode Switch settings are shown in 
Figure 3.7. Make sure the Mode switch is set to 
the “Dual 70V” position.

INPUTS: Connect input wiring for each channel.

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

Connect Channel 1 positive (+) speaker load to 
Channel 1 positive terminal of amp; repeat for
