QSC GX3 300W 2-Channel Power Amp

The QSC GX3 professional power amplifier 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. The GX3 power amplifier is ideal for professional entertainers who require maximum performance and portability on a limited budget. This power amp is ideal for speakers in the 300W (Program) range, supplies maximum possible power to 4-ohm and 8-ohm loads, and features easy hookup and adjustments. The GX3 uses 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 delivers full peak power while preventing detrimental overloads. Dur
