QSC GX3 Professional Stereo Power Amplifier
The QSC GX3 350W Amplifier is ideal for professional entertainers who require maximum performance and portability on a limited budget.
The QSC GX3 features dramatic styling, easy hookup and adjustments, excellent audio quality and QSC reliability. The GX3 delivers just the right amount of power to the most popular speakers used by entertainers. Most 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 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.
