GX amplifiers deliver just the correct amount of power to the preferred 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 conceivable 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 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 at all times right where it must be without excess loss.

GuardRail protection delivers full peak power at the same time as preventing detrimental overloads. All through 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 – 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, at the same time as GuardRail optimizes peak power into the sub and top individually, for greater musical have an effect on and dynamic range.
