Stereo and Mono Modes
Binding Posts
When using the binding post
outputs in stereo or mono modes,
you can terminate your speaker
cables with single or double banana
plugs, spade lugs, or leave them
unterminated (bare wires): unscrew
the amp’s binding posts enough to
reveal the holes on their sides, then
insert your stripped wires (stripped
about 3/8" back) into the holes and
retighten the posts (finger tight is
fine). Be careful that no runaway
strands touch the chassis or other
terminal.
The red posts are labeled “+,”
which means positive. The black
posts are labeled “–” for negative.
You probably know the importance
of getting these correct — if one
speaker is hooked up “in phase” and
the other speaker is “out of phase,”
you’ll be “out of work.” (By the way,
although everyone says “phase” in
this situation, the correct word is
“polarity.”)
Speakons
When using the Speakon outputs in stereo or
mono modes, wire the Speakon connectors as

Bridged Mode
Binding Posts
When using the binding posts in bridge mode,
connect the positive side of the speaker cable to
the CHANNEL 1 red (+) binding post, and connect
the negative side of the speaker cable to the
CHANNEL 2 red (+) binding post. No, that’s not a
typo. You only use the red binding posts in Bridged
mode. Do not use the black posts.

Since bridged mode is a type of mono mode,
turning a stereo amplifier into a single channel
amplifier, use only the CHANNEL 1 input. Turn the
CHANNEL 2 level control all the way down.
