SOURCE: My qsc plx 3402 will not power up

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.

My QSC 1500 LOUD speaker won't turn on why?


I've had QSC power amps with internal fuses in the AC power section, and I have seen the fuse holders separate from the board. These were the 2-piece (per fuse) clips that solder to the board and the fuse clips into them. I'm not sure if you are talking about a speaker, a power amp, or a powered speaker, but if it doesn't power up at all, it's probably in the AC Power Supply area.

How to hook up 18"


Hello!
SO I am going to give you more of a signal layout from the turntables (or whatever you use to DJ) to the speakers.
Turn tables-> Mixer-> Eq-> Amp-> Sub and other speakers.
The part that I am not understanding is why do you need the QSC amp if you have a powered sub? The powered part of that means that there is a built in amp, which eliminates the need for the QSC amp unless you are sending that sound to main (non sub) speakers.
Hope that helps!

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.
