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.

What is your opinion of this product?
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

What is your opinion of this product?
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...
What is your opinion of this product?
...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.

Its more then I expected
What is your opinion of this product?
I bought a pair of Pevey 115 spks, and my fender power mixer did not driver them very well. So I called AMS. and ask what Amp would work well with my set up. I was told to go with the QSC GX5 It was shipped in 2 days, I hooked it up today and the damn thing is killer. It has all the power i need for my BBQ's out side. I'm very happy with the service From AMS. I will be buying more things soon. Thank you guys for all you have done.
