QSC GX3 300 Watt 8 Ohm Power Lightweight Amplifier with Grounded Collector Output System

The QSC GX3 300 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 GX3 clearly represents real value, something everyone can use.

300-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 GX3 is ideal for speakers in the 300-watt (Program) range.

QSC Grounded Collector Output System

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.

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. GX3 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.
