FRUSTRATED - please help!

using a DJM 800. I will be playing through two channels, not clipping just clean signals. Out of nowhere randomly my left output will have a small pop then instantly decrease in volume compared to the right. The signal master output LEDs still show a balanced signal going out. I narrowed the problem to be coming down to the left XLR output. Its not cables or anything like that. The sound will return to normal volume randomly varying in time. Sometimes it will come back in a minute other times half an hour. I dont want to send this out for repairs before I have an idea what the problem is first.

How old is your mixer?.It is a common problem with live sound mixers when with the time and a combination of moist the inputs or outputs become oxidized and even you can not see it at bare eye. You would need either to clean deeply or change your Xlr outputs or the RCA inputs, because you got like a virtual impedance gain by the rust.

my mixer is less than 6 months old. i definitely cannot see any rust of oxidation.

Is it in a coffin?, the only other problem I can see it is a heat one otherwise use your warranty and change it.

You sure it’s not the cables? Did you switch them, play for a while and the problem stayed on the same channel? Sounds like a short somewhere.

its not in a coffin

positive its not cables. once the sound in the left speakers drops, ill switch right to left and the problem moves to the right speaker.

Uh, I would say that’s the cable then.

Exactly my thought :smiley:

If original poster is determind it’s not cable (which it sounds like it is), is the mixer backed up against a wall or something wedging the cable in at a slightly awkward angle?

nope its not being wedged against anything. the strange thing is the audio drop will happen randomly without correlation to anything. Then the audio will come back randomly again.

Check whether the cables are fraying at the joins and that the sheath is across the whole wire. Swap out the cable and see if it fixes it.

Open up the XLR jack and rewire it. Or, if you don’t now how to, buy new good quality XLRs. I’d pretty much guarantee your problem will sdisappear then.

I always buy ones with Neutrik connectors and Van Damme cabling. Can’t go wrong with this combo in my experience.

Something like this:

That, to me Screams bad cable. Do what was suggested and or buy new ones. As for the audio dropping out with no discernable pattern, that’s indicative of a shorted cable.

I think its the XLR port on my mixer… I have switched cables without solving the problem.
