QSC GX5 500 Watt 8 Ohm Power Lightweight Amplifier with Class H System for Professional Quality

The QSC GX5 500 Watt 8 Ohm Power Amplifier is ideal for professional entertainers who require maximum performance and portability on a limited budget. Professional audio quality, meticulous engineering, precision manufacturing, and long-term reliability are all intrinsic to GX. Add contemporary styling, multiple input/output options, and lightweight, and advanced protection circuitry, and the GX5 clearly represents real value, something everyone can use.

500-Watt Range

It delivers just the right amount of power to the most popular speakers used by entertainers. Typically, loudspeaker manufacturers recommend an amplifier with a power output equal to the speaker’s ‘Program (Music) Power’ rating or two times (2x) the ‘Continuous (RMS) Power' rating. The GX5 provides full performance for 500-watt (Program) speakers.

Class H System

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.

Mid-Weight Performance

It features the use of 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.

GuardRail Protection

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. GX5 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.
