INPUTS: Connect input wiring for each channel.
OUTPUTS: Maintain proper polarity (+/–) on
output connectors.
Connect the Channel 1 speaker's positive (+) lead

for negative (–). Repeat each channel wir ing as
for Channel 1. Refer to Section 3.5 for output
connector pin assignments.

OUTPUTS: Connect the speaker across the
posi tive terminals of each channel pair. Do not
use the negative terminals of the channel pair
when the pair is being operated in Bridge-Mono
mode.
NOTe: When operating the channel pair in
Bridge-Mono mode, turn down (full CCW) the

channel of the channel pair. The lower (odd)-
numbered level control works both channels.
