I have a peavey cs800 power amp that works fine but is missing one of the jumpers on the back pannel, witch leaves two of the inputs unuseable. i need another jumper.
do you have a jumper or a diagram to jump manually. thanks very much. gary at gle music ([email protected])

Switch inputs, switch speakers, if not you need to open it up(unplugged from power) and do a visual inspection.. possible bad power/output transistor(s)
I just repaired a cs800 that was intermittant cutting out on one side only- The solder on the boards where the input/output jacks are connected had multiple cold solder joints and had cracked the solder around the pins- Just needed a resolder job.
The Peavey XR8600 is NOT just an amp, but a powered mixer.
To SAFELY use this with your powered speakers, connect those speakers to the MAIN and MONITOR outputs on the front of the unit with 1/4 inch INSTRUMENT rated cables (NOT speaker cables).
To safely leave the power amps in the XR8600 with no output loads, plug GROUNDING plugs into the POWER AMP 1 and 2 input jacks on the front. This will prevent the power amps in the XR8600 from running with no load which COULD damage them.
Make the grounding plugs from 1/4 inch mono plugs by jumpering the centr aand sleeve terminals of the plug.
The preamp section has a problem. It could be anything in the preamp but is OFTEN the input jack itself. They take a lot of abuse.
Also the insert jack contacts that forward the preamp to the power amp if no external FX are used can go bad.
Additional things are circuit board cracks caused by rough handling and also controls that have had the knobs mashed in which can destroy the potentiometers they are connected to.
I'm not quite sure of how the two amps are interacting here, so I'd like to request that you describe the entire hookup. Sending a higher signal from the mixer should not be a problem, but something is wrong in the setup (I think).
Please update this with a description of how you have the mixer and amps connected to the speakers.
Thanks,

If you have a pair, swap the woofers. If the other one works in the cabinet, then it's definitely the speaker. If it doesn't, then you've likely got a problem with the crossover inside the unit. I believe you can get a replacement crossover from Peavey. If it's the speaker, google speaker re-coning in your area, as it's cheaper to re-cone the speaker than replace it.
It could be a problem with the head units remote wire (blue wire) that connects to the amp. It turns on the amp when the head unit is turned on, Check that wire for 12+ volts when head unit is on.
Be sure the amp is properly grounded,and the input and output signal (speaker) wires are connected.
You could also use a temp. jumper wire at the amp by jumping the power and remote terminals, just to see if the amp works.
Note: Do not leave the temp. jumper in place, amps are not meant to be continuously powered up. Make sure it is in a well ventilated area so as to disperse its heat.
please leave it for a couple of days in sun exposure(not connected to power)-and then bring a box or carton bigger than the size of amp and put it in the box with good quantity of rice and leave it for a couple of days(rice absorb the humidity).
