question about behringer mixer

[TLS Guy]

i think it's this mixer:
BEHRINGER: SX3282

i hope it's not the mixer, it's new. the old mixer did this as well, and does not in the new location.

could this be some sort of short/ground? if i had to guess, it might not be the wiggle per se, touching/pushing the socket with a finger might work?

That piece of information pretty well clinches it as being due to external cabling.

From what you say it is likely on the main out wiring on the affected channel.

I would disconnect those first. From your pictures and the online manual, it looks as if you are using the xlr main outs.

If the main outs were shorted then it probably would kill the meter, as they usually get the feed at the end of the chain for obvious reasons.

I would then disconnect any other outputs on the affected channel and use headphones to see which it is. My guess is you have a short somewhere between the main out and the power amp on the affected channel.

This is something that would be easy if you where there, but tricky at long range.

However I would go for the output connections of the affected channel.

I don't see how it could be on the input side.

so our suspect is the XLR cable on the output side to the power amp?
i was not the one who made it, so i will point it out to the person who had that made.

Yes, but you can confirm it. When that channel is out, listening with headphones, pull that main out and see if the channel comes back. I think it will.

Then open the connectors and see which one you have to resolder.
