Is my power amps broken? Please help diagnose!


One side of my amps racked in my PA system is broken (i think)

When I put signal through it (a vocal) the output from the amp is very low and cuts in and out. If i shout and put lots of signal through, it suddenly leaps into life and sounds normal, but only for a couple of seconds and then dies down again.

It's seems if you put lots of signal through it, it almost kicks into action. If you put a normal amount through, the sound it puts out is crackly and very quiet?

Please help!!!!

Probably a bad contact on a strip connector, or bad potentiometer.

i've tried using different channels on my desk. all other amps and graphics etc and have isolated he problem to either the output from my graphic eq, the input to the left side of my amp or the amp itself.
