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

How to I use 2 additional qsc 500 watt power amps to push 6 jbl225x (4) ohm cabinets. I am running unbalanced stereo. Thanks, William


You don't say which QSC Amp. Assuming it is one that can only drive down to 4 ohms you are going to have to run a pair of the jbls in series for each channel of one amp (making the impedance 8 ohms for the pair) and run the other pair from the channels of the other amp. Running unbalanced is not a problem except for interference but you don't say what the source is. If you have more than one output (aux or sub bus for example or poss even a monitor output if you're not using it) it may be beneficial to take one amp from there as you will have some control over the relative levels from the mixer. Otherwise you'll just have to parallel the amps.

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.

Our sound system runs two separate xl 5000 crowns individually to 2 srx728 subs(2241hpl speakers). Amps are run bridged and have been connected to "discrete" inputs on cabinets (I think this is...


More than likely you have lost the speakers... You sent TOO much power to them and likely the voice coils have heated and distorted and are rubbing the pole pieces and hanging up on them. If the voice coils now short some of the windings, next you will lose your amps as well. If you can access the cones, you can try gently moving them in and out with your fingers and you can feel the voice coils rubbing sometimes. REMEMBER ALWAYS check the RMS rating of the speakers against the RMS ratings of the amps... DO NOT fall for the "advertising" things of "peak power" and "program power" ratings... these numbers are to sell equipment... Use RMS continuous ratings when sizing amps to speakers. Typically the RMS continuous ratings are 1/3 of the peak or 1/2 of the program ratings. You will find amplifiers rated either way so you have to dig out the real ratings. In bridged mode the full output of both halves of the amp work together. Your speakers are rated at 1600 Watts continuous... I am not sure I believe that number even... you would be deaf in front of that quickly... Your amps appear to deliver 5000 Watts RMS in bridged mode... over three times what the speaker is rated at. Since you have the amps, set one aside and run each speaker from one side of a single amp NOT using full gain AFTER you get the speakers re-coned. I would recommend putting a fuse in the speaker lead to HELP protect the speakers when repaired.

I have the QSC PLX3602 connect from dbx pa as bridge mono to the sub woofer jbl mrx518. It works well. But now when I change it as stereo to the main jbl mrx515, I only hear the bass sound, no more...


Hi,

I don't think that there's anything wrong with the amp.
I'll think you're using a x-over, connected to the low-output.

Just a shot,

CS-800 buzz in channel a


First a couple of questions:

1) Is the level of buzz controlled by the volume control? Based upon your initial post I would think yes.

2)When you say you want to use the other amp as a regular amp, do you mean to drive a single speaker or more?
