QSC GX3 2 channels, 300 watts/ch at 8Ω, 425 watts/ch at 4Ω

For those who require maximum performance and portability on a limited budget the GX Series amplifiers are ideal for those professional entertainers. The QSC's hallmarks and trademarks brand are all intrinsic to GX, it crafted in precision manufacturing, meticulous engineering, long-term reliability and professional audio quality. Add contemporary styling, light weight, advanced protection circuitry, multiple input/output options, and the GX Series clearly represents real value - something everyone can use. The GX amplifiers is designed to deliver just the perfect amount of power to the most popular speakers used by entertainers. Most of the time, loudspeaker manufacturers recommend an amplifier with power output equal to the speaker’s “Program (Music) Power” rating or two times (2 x) the “Continuous (RMS) Power” rating.

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 system combines maximum thermal efficiency with excellent audio performance. Power levels matched to the most popular speakers. Inputs: XLR, 1/4" TRS and phono. Outputs: Speakon® combo and binding posts.
