Qsc usa 900 power amplifier coming on but no signal.what can be the problem.I check all outputs


Are you then saying you have no sound, yet the amp is on? If so, with the unit off, listen carefully to the top of the amp. When you first push the power button, you should hear one click, followed by another click, about 5-20 seconds later. I'm guessing you hear the first click, but not the second. Is that correct? If this is correct, and you are interested in having your QSC repaired, Please visit my website at audioserviceclinic.com. You may contact me there. Thank you.

My qsc plx 3402 will not power up. I believe I shorted it out with my speaker cables


Most likely...shorted speaker wires, defective speakers or too many cabinets wired together can blow a amplifier channel in an instant. Manufacturers use to mount protection fuses on the exterior of equipment but people started replacing 3 amp with 25 amp automobile fuses and destroying internal circuits. You could pop the cover to look for a power supply protection fuse (same value replacement please) BUT be careful as there are sustained voltages after the unit is disconnected from the AC outlet that hold enough power to make this type work dangerous. I recommend sending it to a professional repair shop for a checkout and estimate.

How do I bridge my QSC GX 3 amp to run one speaker cabinet?


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

I have a mx1500a qsc power amp and i was wondering do i need to rewire a tip/ ring/sleeve cable to make the proper connection to the input of the amp? coming from a snake can i just plug an instrument...


Hi,

The best way is to make a new cable and connect the tip and sleeve.
Thats the best way to run your QSC, then you're using the balanced input.
But thats only working when the rest of the system is also balanced (snake etc).
Offcourse you can use your instrumentcable, but that is unbalanced and you will loose some gain.

Regards,
Gerard

PLX 3402 MUDDYSOUND AFTER A FEW MINUTES OF USE


The amplifiers protection circuit when active will lower the volume significantly and sound poor. Is the amp driving an impedance it's happy with, not being overdriven and has adequate ventilation? Do the fans appear to work ok?
