Question about QSC MX1500A 2-Channel Amplifier

1 Answer

QSC 1420 pwr amp

Using this pwr amp to power a berringer 8 channel mixer. Channel 2 was giving a weaker signal than channel one and then channel two stopped working all together. Had a professional sound shop work on amp and after a $200.00 charge the tech said he had to re sodder the connections in channel two. Got it home...hooked it up and now same exact problem on channel 1. What's the chances it's the same thing? Wouldn't a tech person charging $200 check out all the connections?

The weaker signal caused by leaky capacitor and change value resistor is need to replaced with a new one so it's works normal again. Your tech did is re soldering the cold solder he did not replaced some defected parts.

Hope it may help you;

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.

Where do you have the gain control set on the Mic channel ?
If you have no issues with either the speakers or the Mic, and the gain control for the channel you have the Mic plugged into is set at a somewhat "normal" position, you might have a problem with the mixer itself.

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!

I use a Mackie 1604vlz board. I have Passive EV Speakers that I use a QSC power amp for. I want to add one Powered Subwoofer to this. How can I hook up without buying a crossover? Can I run out frome the...


You can, but I would not suggest it. Depending upon the input design of the powered sub, the highs might not get filtered out. Many subs assume that they are only receiving the lows. You are better off using a crossover between the mixer and the amp for highs and the powered sub for the lows. Please note that the crossover will give you much more control over the sound quality.

How can I use my Marantz 4070, Quadro Integrated Amplifier as an amp for guitar, microfons and so on?


you need to buy a small mixer like the 4 channel beringer (about 90 bucks) you would plug its output into the inpur of your Marantz and will then be using it as a power amp. It should work great and the little berringer even has phantom power I believe.

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.
