Gem sound xp-350 clipping

I have 2 Gem sound XP-350's I use with my PA. My intent was to use them for monitors. I run 4 monitor mixes. When I run the CD player the amps work fine. But when we perform live the amps keep cliping and sutting down. What am I doing wrong? I can't deal with this I want to toss them off a high rise.

Hi There,

You have given me a good clue to your problem....

You say that the CD player goes well and does not shut the system down like the Live connections. This is a single input configuration...

This means that there is sound levels coming in from the live multiple connections that are too strong (Loud) for the amp to handle...
Its a good amp you have as its shutting down to protect itself instead of blowing up....
So.... set up for the live show then disconnect all but one of the live inputs and start the live session if its OK, then connect another of the live connections, and see if its OK, if it is then connect another live one connecting each one progressively until the problem occurs again...this last live connection is the one that is too loud in signal strength for the amp to handle causing the shut down...

Solution is to reduce tha signal on that last cable source to a level that stops the shut down...I remember that groups of guitar players have volume controls on each guitar and if these are set too high then this can occur....specially if they are all using the same amp without a controlled "mixer man" monitoring each input signal.
Rember the small meters on the mixing panel which have a green painted area and a red painted area the "mixer man" must keep the each meter needle in the green zone for all the inputs otherwise a shut down occurs.
Hope this helps you...

Cheers From

Try going to the Dell or Microsoft Websites and loading a new display driver for Windows 7. When I first got Windows 7, both my monitor and printers required new drivers for Windows 7. It seems that Vista and XP drivers for a lot of things don't work on Win 7.

Good Luck

I have a GEM 17" with power issues!

Sounds like your power supply capacitors are causing the power supply to shut down. Or you have a short in the monitor loading the power supply. You should try a different power supply.

Gem Sound clipping problem

First of all the EXA-3940 is rated at 350watts per channel in to 8 ohms. The 1400 watts is bridged into a 4 ohm load. Second, the speakers can handle 1000Wats peak with an average of 600 continuous (i'm guessing). That tells me that the amp is underpowered for the speakers. The sensitivity of the amp is such that the mixer is overdriving the input stage. That is what is causing the clipping. If you are looking for more volume, you are probably better off purchasing another amp and running them in bridge mode, 1 per speaker cab. Be careful though, not to overdrive the speaker cabinets either.
