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.

Two possibilities here, one is a cracked pin on one of the power supply UF diodes and the other one that the power output devices got fried.

My QSC PLX 2502 amp completely blew. Channel 1 has been giving me problems for a year and I have had the amp about 3 years. This past week it drove into the red so much and I could not stop it. Well now...


You should NOT drive the amplifier into the clipping mode continuously. There is a possibility that you have fried your speakers or that they are the real problem. You haven't told us what you were driving, however this amp will deliver 450 Watts per side RMS at 8 ohms which means your speakers have to be rated at least that much RMS power for continuous. When speaker voice coils fry, they can wipe out amplifiers. Let us know what speakers you are using and how they are configured. This amp is going to be expensive to repair I can tell by looking at the schematic: Here is the schematic:

http://elektrotanya.com/qsc_plx2502.pdf/download.html

Scroll down to "get manual" and click to download it. IGNORE other download links.

This amp has circuits to boost the power supplies to the amps to handle the peaks. It is rather complex but the schematics are complete and have good explanations... some of the best I have seen. There are going to be a lot of destroyed components and great care has to be used after repair to "cold start" the unit to make sure nothing else is bad or it will blow up again. Most people do NOT have trouble with the QSC amps... so do tell me what speakers you are using and how they are configured so we can verify the design is correct. This amp is rated for 8 ohms so USUALLY only ONE speaker can be connected per side... and finding an 8 ohm speaker that can take 450 watts continuous RMS isn't easy. People fall for the advertising claiming "Peak" and "Program" power which are FAKE advertising... ONLY use continuous RMS power when sizing amps and speakers. There are MANY ways to cook out equipment... One is to boost the bass or the treble way up. Another is to NOT use balanced interconnect lines between mixers and your amps. Yet another is to NOT power ALL interconnected equipment from a single receptacle or power conditioning module. Please describe your setup further so I can help you more!

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? kenshireman@msn.com


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.
