A Lightweight Power Amp That Really Packs a Punch!The QSC GX5 700-watt power amplifier gives your speakers the power they need while giving you the efficiency and protective features you want for easy operation and peace of mind. The GX5 uses advanced components for both light weight and reliability. Its Guardrail protection allows delivery of peak power while preventing overloads. It's equipped with a crossover switch, so adding a subwoofer to your system is a snap. Optimized for 4- and 8-ohm speakers, this amp also fits perfectly into popular racks, and its lightweight design (less than 30 lbs.) makes the GX5 incredibly easy to transport.
QSC GX5 700-watt Power Amplifier at a Glance:
The right amount of power for your application
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 the "Continuous (RMS) Power" rating.
The GX5 provides full performance for 500 watt (Program) speakers. It 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.
The GX5 uses a Class H system, based on key elements of the PLX Series, 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.
Both the 700-watt GX5 and 425-watt GX3 amplifiers use 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. As always, the amplifiers are fully protected from the usual hazards of the trade, ensuring stable performance and long life.
GuardRail: protection from overloads
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-ready when you are
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 20Hz-100Hz to the sub (Ch 1) and 100Hz-20kHz 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.

QSC- The only choice!
by Scott from Findlay, OHThis is one of the QSC amps that I own. I am completely satisfied with this amp and it's quality, features, and pristine sound! I have used this both in stereo mode and also in the crossover mode an... read more [+]d it performs exceptionally well under both conditions. Drives subs without any problems and runs cool for hours and hours all while maintaining that great sound that I love from QSC amps. I have used many different brand amps over the years (running live sound) and I much prefer QSC over Crown ANYDAY! I feel QSC's are more dynamic and have better sound quality and they hold up longer (proven to me many times). They are used by many sound companies for that very reason. This is truly a great amp for live sound as well as DJing. QSC has done it, again! close [-]
