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.

• The GX3 is ideal for speakers in the 300 watt (Program) range, while the GX5 provides full performance for 500 watt (Program) speakers.
•  The GX7 outputs 725 watts into an 8 ohm load. Owners of popular 4 ohm loudspeakers (such as dual-woofer, two-way models) will find the 700 watt (4 ohm) power of the GX5 an ideal match while the GX7's 1000 watts will very capably power many of today's popular subwoofers or two typical 8 ohm speakers per channel.
• 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.
