GX Series
GX Series amplifiers are ideal for professional entertainers who require maximum performance and portability on a limited budget. The hallmarks of the QSC brand – professional audio quality, meticulous engineering, precision manufacturing and long-term reliability – are all intrinsic to GX. Add contemporary styling, multiple input/output options, light weight, and advanced protection circuitry, and the GX Series clearly represents real value – something everyone can use.
Power levels matched to the most popular speakers used by entertainersOptimized for maximum real-world headroom into 4- and 8-ohm speaker systemsInputs: XLR, 1/4-inch TRS and phono input connectors for compatibility with any sourceOutputs: Speakon combo accepts 1/4-inch (TS) plugs or Speakon 2- and 4-pole plugs (connects 2 poles only). Binding posts support all other speaker wiring systemsMinimum depth chassis (10.1-inch / 257 mm) fits in compact, inexpensive effects racksDetented gain controls for precise setting and matching of sensitivityGuardRail automatically protects the amplifier and loudspeakers from damage due to temperature rise or overdrive without shutting down the showFront panel LEDs monitor power, signal, and clippingSubwoofer/satellite crossover built-in
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.

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.
GX3 Power Amplifier
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.

GX5 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 GX5 provides full performance for 500 W loudspeakers.
GX5 Power Amplifier
The GX5 uses a Class H system, almost doubling its output power compared to amplifiers 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.
