I have never repaired a power amp and I wondered if I could get some
pointers for troubleshooting this unit. It's a QSC CX4T. The symptom
written on the ticket is no audio output. I plugged the unit in and it
DOES power on so I assume that power suppy and fan are operating
properly. QSC faxed me a schematic, but their fax machine is so crappy
that I can't make out any of the component numbers.
Can someone describe to me the basic flow of the signal in a power
amp and give me some starting points to go after? The only tools I
have is a scope and a digital multimeter. I don't have a signal
generator so if you have any "poor man ideas" please let me know.
Here is a link to the pdf for the unit if it will help you any:

Thanks for any possible help!
