Tapco J1400 User Manual

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.”)

When using the Speakon outputs in stereo or 

mono modes, wire the Speakon connectors as 
shown below:

Stereo and Mono Speakon Connection

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.

Bridged Binding Post Connection

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.

When using bridge mode, wire the Speakon 

connector as follows:
