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.
Please specify a bit more, does the rattle is physical(Enclosure structure) or electronically hear thru speaker(Power Amp Common Issue)? I have the solution for the amp issue, let me know.
A common issue with the QSC RMX series amp is faulty volume pots, so i would recommend go this way first of all, let me know a bit more to improve help.
Unless you are a qualified audio service technician, you should refer repair of this unit to an authorized Behringer service depot. The capacitors you refer to can store lethal amounts of electrical charge. Also, Behringer service manuals and schematics are notoriously difficult to get.
One side is in protect if your wired in stereo.The other side is working fine.You have to take that to an experienced electronics technichan that deals with pro audio.It will cost you 40+ dollars for a diagnosis but that amp is probably dead.I would suggest save up for a crown or qsc amp.
Got asilimar problemwit a behringer europower pmh 3000. my
The Right channel began to crack up and drizzle now it seems completely dead. Changed the cables both of input and seapkers , still the problem stays the same. Any suggestion before brigning for a month at the repair shop? And get out with a 200-400$ bill ?
Hello pare ko. EP2500 is a pro amp, manufacturer says that. Notorious to me. Got 5 of these for repair. Clip is of course cause by too much signal from source. If the amp is still clipped or on protect even w/out signal in, time to open and do repairs inside. usually a MOSFET inside P50N06 (50V-60A) is kaput. or MJE15033G and MJE15032G. Now if blowing main Fuse, main txistor 2SA1943/2SC5200 maybe gone. Read carefully the setting of your dip switches setting at the back. This amp can drive 750 watts/ch@4 ohms.
