QSC’s GX Series amplifiers are perfect for musicians and professional entertainers who require reliability and great sound quality oat a value price. QSC’s reputation for solid engineering, great build quality and ultimate reliability is upheld in every GX amplifier. Add fresh styling, a choice of I/O options, light weight, and solid protection circuitry, and the GX Series clearly represents a great deal for everyone who needs solid dependable power.
GX amplifiers have just the right amount of power for most popular speakers used by musicians and entertainers. Typically, loudspeaker manufacturers say an amplifier should have power output equal to the speaker’s Program (Music) Power rating or two times (2 x) the Continuous (RMS) Power rating.
The GX5 delivers optimal performance for 500 watt (Program) speakers. Owners of popular 4 ohm speakers (such as dual-woofer, two-way models) will find a perfect match in the 700 watt (4 ohm) power of the GX5
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.
GX Series 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, GX Series amplifiers are fully protected from the usual hazards of the trade, ensuring stable performance and long life.
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.
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.
