QSC GX3 Power Amplifier
Maximum performance at a modest price plus flexible I/O. The QSC GX3 Stereo Power Amplifier 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 power amp while reducing raw material cost and weight. The rackmount GX3 power amplifier is ideal for speakers in the 300W (Program) range and supplies maximum possible power to 4 ohm and 8 ohm loads. The GX3 power amp uses the latest QSC Grounded Collector output system for optimum cooling of the critical power transistors. The GX3 power amp's true Class B biasing system combines maximum thermal efficiency with excellent audio performance.
