Product Description
QSC GX5 500-Watt Power Amplifier
QSC GX5 Stereo Power Amplifier
The QSC GX5 Stereo Power Amplifier is ideal for professional entertainers who require maximum performance and portability on a limited budget. 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 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.
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 - 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.

GX3 Power Amplifier
GX amplifiers deliver just the right amount of power to the most popular loudspeakers used by entertainers. Typically, loudspeaker manufacturers recommend an amplifier with power output equal to the loudspeaker's Program (Music) Power rating or two times (2x) the Continuous (RMS) Power rating.
The GX3 is ideal for loudspeakers in the 300 W range.
GX3 Power Amplifier
The 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.
Both 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 downsized chassis.

Very clean and clear
Played it for 8 hours straight with the clip light flickering very high volume and it didnt flinch
Great for small bars or clubs and even small outdoor concerts
Clean, quiet PA amplifier. But don't mistake using this amp for casual home listening. This is after-all, a professional entertainer series PA power amplifier geared toward use in a high decibel public entertainment environment. If QSC quality is desirable in a home listening application I would suggest consideration of the purchase of either a QSC studio-quality RMX Series or Cinema sound DCA Series amplifier. I'm using this gear for DJ dance music paired with Seismic Audio Dual 15-inch mains with a 100 decibel sensitivity of 1 watt @ 1 meter for a total kickin' max output of 134+ decibels! Not chamber music.
