we did a soundcheck saturday and our PA started to crap out you'd hit a high note and it would break up then it would get quiet (too quiet...lol) anyway then it would do ok then crap out ....took it to th local guy and of course it worked fine, said we were hooking it up wrong, (th same wrong way for 2 years) so we go back and guess what ,does it again ,they were kind enough to let us use an inhouse one FREE of charge (there's one for the GC haters)... so my question is anyone know what my troubles might be it's a Peavey XR680s...gonna send it off tomorrow just thought i'd get and idea from you guys ....thanks in advance
 
troubles with Peavey!! WOW :) It might be your amp, EQ, Crossover, Mixer. Did you try going direct from you mixer to the amp and see if it was the EQ or Crossover. Try a differant mixer. Then try a differant amp. Just take it one step at a time
 
If I'm mistaken, that's a powered mixer. When it's all-in-one, it's hard to troubleshoot. You did not mention it was only happening on one side vs. another or it was a specific channel. That makes me think the problem is possibly in the final power section or in the power supply. It could be anything from a component to a cold solder joint. The technician is going to have to wait until the output craps out to test it or start shot-gunning parts. Good luck.
 
Stop it :) Peavey makes very reliable gear. I worked for a retailer for six years and saw much more defective gear from Fender, Marshall, Mackie, Korg, and Roland than I ever saw from Peavey.

The xr680 is a powered mixer. Hard to t/s different parts. Like dw said, it could be any number of things. Usually I substitute cables first, then clean all the jacks, and check my speakers. Simple is first in troubleshooting. Intermittent stuff like that could be a bad ribbon cable or solder joint somewhere. Many is the time I pull something apart, resolder a couple things, and problem solved.
 
i have a yamaha emx 5000 p.a. head-mixer and the limiter circuit would come on and squash the volume especially when more than a couple things were plugged in. it also didnt like high impediance signals like electronic drums keys and line 6 pods. mics by themselves were o.k. but it cut out whenever there was a surge in vocal parts with alot of drum action and bass going on at once. yamaha admited to problems with the limiter circuit and did a mod for free. i also found that using the eq (the last band) and lowereing the real low stuff like under 80 hz and a little 250hz made the power amp in it work better because those built in power amps work real hard at processing the low stuff.
 
I'm a Crest dealer which is owned by Peavey and Crest has great reliablity. Peavey has turned it's self around in the last few years. I think it started when they bought Crest and saw how it should be done. I remember when you wanted it to hiss you bought Peavey. I haven't used anything Peavey in several years but have heard good things.
 
gemsbok....

may have something there it seems something with 250 k band was in play but th vox crapping out under a surge was just like what we had but only th one voc mike was being tested ...thanks for all the input ...and I'm not crapping on peavey if i don't fix this one i'll still buy peavey this is the first problem i've had with it and i've had it for almost 9 years and it may have been a year old and i gave 500$s for it so yeah i'm peavey sold thanks again
