It is not passing it's self test. check the usual suspects (shorted output transistors, blown mini fuse, and that annoying pcb mount fuse in the power supply (looks like a resistor with one stipe)) if they all check out, test the relay coil for continuity. if it is open then replace the relay, but if it reads below 200 ohms the relay is ok, and i'd bring it to the shop for more extensive testing and repair.

For QSC amps the GX series are not bridgeable. You will have to run one speaker to each channel.

My QSC GX3 has a red light that turned on (on the front panel). The channel is not working. Is this a fuse or something else?


You should check the speaker set, maybe it's short circuit.
Try remove the speaker set from the unit, than switch on the amplifier again, if the red light still on, surely the final drive is damages( Transistors or IC's).
Replace it with new ones.

Peavey cs800x a channel drive board what goes bad?


Hi,

A bit late, but I'll give it a try.
You can measure the outputsignal before the relay.
Often there's a coil, measure if you've got a DC level at that point.
If so, you're power amp is down.
Normally when the relay doesn't switch there's a DC level in your amp.

Cheers, Gerard

There is a bad connection in the other channel or the speaker relay has a bad contact in it.
