Dear Forum users,
I have recently bought an old PA-400 mixer power amplifier (see attached pictures). I intend to send a stereo signal from a guitar effects board to the amplifier (either through A B inputs or AUX input), however, I can only get a mono signal to the speakers. Does anyone know if the PA-400 does not support stereo signal out? I have read the manual, which does not mention mono or stereo output at all.
Best,
Rikki

Re: PA-400 mixer power amplifier
It is a mono amp.
You will note that each channel does not have a pan or balance control. There is only one power amp in the thing.

Re: PA-400 mixer power amplifier
To put a bit of perspective on it: stereo does not make much sense with long-throw speakers (too much cancellation and/or too little spatialisation) and 400W does not make much sense with short-throw speakers. So there is a point in using one or several mono amps without shared instrumental sources on stage. Stereo effects and mixes are more useful for recording/broadcasting or for comparatively small venues. But for the latter, going by instrument amps may be simplest again unless you prefer giving a sound guy the last word on your acoustic footprint.

Hi.
I have bought recently a PEAVEY PA 400.
I used it as bass amp, ans it's pretty powerfull!
Does anyone know how to use the low scan or the high scan pots, properly?
Have a nice day!
Sincerely

Re: PA-400 mixer power amplifier
You have master bass, middle, and treble controls The scan controls are simply the crossover point between them. Look at the printed scale under each knob. Lke a parametric.
