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.

Re: gem sound xp-350 clipping
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...

Without hearing it it is difficult to be sure what is going on. What happens if you plug the main PA into the monitor channels, do you get the same? Are you trying to get too much into the monitors? static and popping are not the same to my ears, popping sounds more like you are hearing something that's there through the monitors that you're not hearing through the main mix as it may be masked. What frequency is the popping? Does it only happen when levels are high or when the singers are doing 'p' and 'b's etc? do you get it if you put the monitors on the main mix? Are you running the monitors into clipping (although I wouldn't expect this to create a popping? It sounds like a mix issue rather than a fault with hardware.
This mixer will run 2 8 ohm cabinets per side, if this is an older unit, it has only one NL2/combo jack per channel....with the button on the front panel in the Main Monitor position you can run 2 main cabinets and 2 monitor cabinets, you will have to daisy chain your speakers.All speakers powered from the back of the unit must be passive, no powered speakers.....if you want to use this head just to run moitors and run a pair of powered mains then connect the jack on the front that says main out to input of your powered speakers, hopefully your powered speakers can be daisy chained at low level, then if you want to use the 8600 to power only monitors, get a 1/4 in y cable and plug it into monitor out on the front of the mixer and then plug it into PA 1 and PA 2 to the right there and both sides will now be the monitor mix from this mixer and it will run 2 speakers per side, as long as the cabinets are 8 ohms.
Yes you can,you will need 2 run ,1\4 in 2 jack 1\4 in imput too the mic\line imput your chaing your signal so you will need too preset vol levels on the 120 too your desired max peak out put buy first putting you output slide too max on your mixer (running a signal from a cd player or other divice into mixer)then turn vol up 2 disered max loudness you want to run sound at then lower the vol using out put from main power slide on your mixer. Its called chaining your componets .better way of hooking up a band on a small system.ywc Rev bob dj 25yrs exp
A high-pitch squeal is common in CRT TV sets and monitors. I've never run across this in an LCD monitor, but there's a first time for everything. If the sound isn't coming through built-in speakers (if this model has them) and is being caused by the computer, I would suspect the inverter circuitry. This provides power for the backlight, and there are transformers that may have become noisy. Because of their construction, it's possible for them to vibrate internally, and at a frequency that you hear as the high-pitched noise. There isn't a lot you can do to quiet them. When I worked on TV sets, I had mixed success using hot-melt glue to muffle the noise, but usually the only way to completely cure the problem was to replace the parts. It's unlikely you'll find the parts available for a monitor, so all I can suggest is to bear with the noise as long as the monitor is otherwise working properly. Or use this as an excuse to buy a new LCD monitor; they are quite reasonably priced these days.
There are a number of configurations for a mixer like the 1832, the most common are PA system and Recording system.
There are Main output jacks which carry the mix as summed in the main faders. These in a PA system would feed the pa amplifiers which drive the house speaker system for the audience. These connectors are XLR 3 pin type on the rear, intended for professional pa amplifiers which use balanced +4dbv line input level. Amplifier which have 3 pin XLR connectors for input signals can accept that high level signal. For home style HiFi amplifiers, the signal level is nominally -10DBv and balanced or unbalanced signal lines with 1/4in diameter phone plugs which are connected to the mixer by way of a second set of Main output connectors which are 1/4in phone jacks. Use whichever amplifier input level your amp has.
If you are not using it as a main PA house mixer, but using it for recording, the main output connectors go to a 2 channel recorder or computer sound card recorder.
The power amp and your monitor speakers are connected to the connectors labeled "Control Room" (CTRL Rm). These output are useful for recording because the signal through the mixer can be monitored from several buses, Solo, main mix, selected by buttons provided. The buttons only affect the signal heard through the control room monitors, and not the main output which only sees the main mix so selecting "solo" does not interrupt the signal going to the recorder while the engineer in the control can be checking other signal paths through the board.
