Mixer amp with output problems

Recommended Posts

We have a Behringer pmp1000 mixer amp with a problem on the sound output side and the whole thing cuts out we can sometimes get one speaker working , [ but we know all the input channels are working as all the lights flash showing the sound levels this is an intermittent fault therefore making it difficult to find, even the local electronics dealer keeps having trouble sorting this problem and of course this also attracts labour costs and is not sorting the problem.

 

We are wondering if we cold use the Behringer as a mixer and bypass the sound output by taking a line out from the mixer to a line in on another amplifier using this on the sound side. Hopefully somebody can give us some thoughts on this problem , As a very small amateur group we cant really afford to replace the mixer amp at the moment

If the problem is with the power amp, then the two outputs labeled "Main Out" should be able to send a signal a different amp.

 

You could try, if you've not already done so, a couple of short patch leads between the "Main Out" and "Power Amp Insert" sockets, as these will be switched jacks & a little dirt in these could be the cause of the problems. Use an unbalanced lead for this as these are inserts, not balanced inputs.
