The GX3 Stereo Power Amplifier from QSC is ideal for professional entertainers who require maximum performance and portability on a limited budget. QSC designers have optimized output and appearance of the GX3, while reducing raw material cost and weight. The rackmount GX3 power amp is ideal for speakers in the 300 watt (Program) range and supplies maximum possible power to 4 ohm and 8 ohm loads.

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.
