Product Description
GX Series amplifiers are ideal for professional entertainers who require maximum performance and portability on a limited budget. QSC designers, headed by Pat Quilter, have optimized output and appearance while reducing raw material cost and weight. It's all here dramatic styling, easy hookup and adjustments, excellent audio quality and QSC reliability. GX amplifiers deliver just the right amount of power to the most popular speakers used by entertainers. Most loudspeaker manufacturers recommend an amplifier with power output equal to the speaker's "Program (Music) Power" rating or two times (2 x) the "Continuous (RMS) Power" rating. The GX3 is ideal for speakers in the 300 watt (Program) range, supplying maximum possible power to 4 ohm and 8 ohm loads.Technical NotesThe GX3 uses the latest evolution of the QSC Grounded Collector output system, for optimum cooling of the critical power transistors. A true Class B biasing system combines maximum thermal efficiency with excellent audio performance. GuardRailGuardRail protection delivers full peak power while preventing detrimental overloads. During excessive clipping, or extreme overheating, GuardRail reduces gain just enough to preserve the integrity of the music, protect the speakers and keep the audience excited, without unprofessional distortion levels or shutdowns. Subwoofer/Satellite Crossover A subwoofer reduces strain on the full-range speaker, allowing it to play louder, or letting a smaller speaker do the same job. The GX Series supports this mode with a Crossover switch that splits the full-range input entering Ch 1, sending 20 Hz - 100 Hz to the sub (Ch 1) and 100 Hz - 20 kHz to the top box (Ch 2). The front panel gain controls balance the sub and top box, while GuardRail optimizes peak power into the sub and top individually, for greater musical impact and dynamic range.Features:Power levels matched to the most popular speakers used by entertainers Optimized for maxi...

I started looking around for a performance power amp that was in between crown and Behringer. Now while I consider Crown the holy grail of power amps, I didn't feel like spending the cash for the Harley-Davidson of power amps. So when looking, I actually took a look at parts express and their most popular power amps. To me, the majority of the people that visit that site have their head screwed on straight and care about quality products. While a lot of the reviews showed promise for Behringer, my cousin and I currently employ a tube based preamp in my studio, and while it worked flawlessly in the beginning, all the pot's on my preamp are now fuzzy and buzzy. His preamp sucked from day one, buzzing at 60Hz, requiring post process filtering which saps the nuances out of the recording. To sum up my opposition to Behringer, I didn't feel like getting a product that worked well for a year or two, though I just bought a Behringer 8-channel mixer to go with it ($60 and not regretting it yet, but we'll see)
Hooking it up to my 6.5" jbl studio s26-ii's, I was blown away by its punch and clarity. Mind you, its normally being driven by an 80W/ch Onkyo (0.08%THD). The speakers had more dynamic to the sound, and it was absolutely fantastic. I had done this while I awaited the arrival of my MTX PA speakers.
I bought a pair of MTX TP2400 to go along with it. They are definitely not the greatest speaker out there, but they put out the high SPL sound I was looking for in a live performance. The amplifier drives them pretty well, though I cant help but be slightly disappointed with the result. I am confident that the amp is not the culprit though due to how well it has driven my other smaller studio speakers.
I think these cheap PA speakers really show the beauty of the amp though, Its speaker/clipping protection made the music stay at uninterrupted high levels. The other great thing is the 6 year transferable warranty. While I don't really care too much about warranties, Behringer's abysmal 1 year warranty pushed me over to QSC. That's pretty much saying what I think about my current products, they know its too risky to warranty a product longer than a year.
I hope you find this info useful, because these guys deserve every sale they get.

Fan noise is very audible. Otherwise does the job. Maybe OK for a gig but not if you play at home in a room. The noise is pretty loud and very audible. I am returning this item...

Positives:
QSC name - rock solid
Construction - rock solid
Power - very solid
Technology - this is a cool "True Type B" amp - rare, slick, something to talk about, sounds great
Warranty - 6yrs
Operation - fast start-up and shut-down. No pops. Starts up in 1sec or less, no waiting.
Inputs/Outputs: very flexible, including RCA, great for home use
Value - tremendous value for the money
Negative
Noisy fan - can replace or mod if you desire. Or turn up the volume
Overall, I have no qualms recommending this amp for any type of use as long as you realize that yes the fan is noisy. Very solid amp, I use it everyday to drive hi-end home speakers and really enjoy it.
