The QSC 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 audio amplifier system combines maximum thermal efficiency with excellent audio performance. The GX3 is ideal for speakers in the 300 watt (Program) range. It supplies maximum possible power to 4 ohm and 8 ohm loads. QSC designers have optimized output and appearance while reducing raw material cost and weight. It's all here in this audio amplifier - dramatic styling, easy hookup and adjustments, excellent audio quality and QSC reliability.
