QSC GX3 Professional Power Amplifier 2 Channels 300WithCh at 8Ohm 425WithCh at 4Ohm

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.

GX amplifiers deliver just the right amount of power to the most popular speakers used by entertainers. The GX3 is ideal for speakers in the 300 watt (Program) range. 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. The GX3 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.

As always, GX Series amplifiers are fully protected from the usual hazards of the trade, ensuring stable performance and long life. 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. GuardRail optimizes peak power into the sub and top individually, for greater musical impact and dynamic range. Power levels matched to the most popular speakers used by entertainers. Optimized for maximum real-world headroom into 4 ohm and 8 ohm speaker systems.

Inputs: XLR, 1/4 TRS and phono input connectors for compatibility with any source. Outputs: Speakon® combo accepts, 1/4 (TS) plugs or Speakon 2-pole and 4-pole plugs (connects 2 poles only). Binding posts support all other speaker wiring systems. Minimum depth chassis (10.1/257 mm) fits in compact, inexpensive effects racks. Lightweight - weighs less than 26 lbs (12.5 kg).

Detented gain controls for precise setting and matching of sensitivity. GuardRail automatically protects the amplifier and loudspeakers from damage due to temperature rise or overdrive without shutting down the show. Front panel LEDs monitor Power, Signal and Clipping.
