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 You may contact me there. Thank you.

I have a QSC RMX 2450 in which both channels are driven even though the amp is in stereo mode and I am only sending a signal into input channel one. It acts as if the amp is in parallel mode but I have...

My thoughts are that the amp has a poor channel separation but usually you can only hear a very quiet trace of the sound through the undriven channel. I agree with Taurus and make sure that the switch is making contact and moving all the pins to the proper points. This is a Home stereo amp, it comes with an extended 6 year warranty if you register it, I would check into getting a warranty repair before doing anything to it! Looks like a nice quality piece, those dip switches are a little bit confusing but the way it's built it is necessary to have them. It has a Dual Mono amp section so there is no way that any sound can be crossing over unless the swithches are directing it. The only way that can happen is in Parallel or in Mono. You could be in Stereo / Mono which would input both channels and output 3 settings a 1, 2 in Stereo & a Mono, Try hooking a speaker up to the Mono/ Bridge outputs and see if it's louder than just hooked up to 1 or 2. Parallel inputs will give you Mono 1 & 2 with Bridge off, and might give you Mono 1 & 2 with a bridged Mono if the bridge is on, like 3 channels all mono with one getting twice as much power as the 1 & 2 will put out. Although they have it labeled to not use it in those settings it's possible to do. I can see why you would be checking the switches.
It may actually be labeled incorrectly , as strange as it seems, many Chinese products have been made with labeling errors. Plus and minus have been wrong on Asian Made car amps so it's not that inconceivable that this may have some incorrect settings shown?

MAckie 1604 VLZ Pro Mixer, running QSC 1850 with jbl's from main outs. I would like to hook up powered subwoofers. What is the correct pathway?

The best way is to use a two-way crossover between the mixer and the amplifiers. In your case, the low output from teh crossover would go to the powered subs, the highs to the QSC. Use the crossover adjustment to set the frequency crossover point to get the sound quality you require.


Mackie 1604 ---> Crossover --- Highs ---> QSC --->Speakers
-----> Crossover --- Lows ---> Powered Subs.

My QSC GX3 has a red light that turned on (on the front panel). The channel is not working. Is this a fuse or something else?

You should check the speaker set, maybe it's short circuit.
Try remove the speaker set from the unit, than switch on the amplifier again, if the red light still on, surely the final drive is damages( Transistors or IC's).
Replace it with new ones.
