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 GX5 supplies maximum possible power to 4 ohm and 8 ohm loads. Owners of popular 4 ohm loudspeakers (dual-woofer, two-way models and many subwoofers) will find the 700 watt (4 ohm) power of the GX5 an ideal match.

Technical Notes
The GX5 uses a Class H system, based on key elements of the PL Series, (PLX, PL3, CX, DCA) almost doubling power in the same size and weight. QSC design expertise allows the output devices to shift from low-power to high-power rails in less than a millionth of a second, ensuring that the output power is always right where it needs to be without excess loss.

QSC GX5 uses premium toroidal power transformers for reliable mid-weight performance. A variable-speed fan moves air crosswise through the amplifier, drawing cool air in over the power transformer, through the fan, and then over the heat sink. This keeps the transformer cool and allows a full size heat sink to fit in a down-sized chassis.br />
GuardRail
GuardRail 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.

One of the best amps I’ve ever used!!

Product Review

Looking for the proper power amp is quite a chore. So I checked the website looking for a power amp that would fit the needs of my band. I wanted something that could easily be used for smaller to medium venues and occasionally for a few bigger venues. I needed something that could push our sound and not worry about it cutting out during the middle of a show. I happened to come across the QSC power amp. I always knew that QSC was a professional brand, but I had never tried QSC before. I pulled the trigger and I can say I have not been disappointed! We have played smaller and medium venues and the QSC has not let us down. We have plenty of power, and even some to spare. So if you’re looking for a power amp that can carry your sound, then look no further!

I bought this amp to power my EV Elx 112 tops. This amp has exceeded performance I expected. This amp is replacing my crown XLS602. I would definitely buy another. You really can’t find a better amp for the price

Product Review

I purchased this amp to run monitors for the church PA. The church is small. As soon as I hook it up you can hear it running. I was hoping during service you wouldn’t be able to hear it. Well you can. Other than that it works.

Does what it's supposed to do...

Product Review

...Powers my speakers to ear bleeding levels!! Saw some other amps at this power level that did NOT have cooling fans... My uneducated logic figured I'd rather have the cooling at the volume I was planning on listening to. Read some whining about fan noise but I don't get it....once the music starts, you don't hear it. Price was reasonable, IMHO, and AMS "rocks" with their billing option. Pay off your card every month and ZERO interest. A simple 2 channel amp to listen to pure stereo at levels that a 7/9/11 channel A/V receiver can't reach.
