The GX3 power amplifier is ideal for professional entertainers who require maximum performance and portability on a limited budget. The hallmarks of the QSC brand - professional audio quality, meticulous engineering, precision manufacturing and long-term reliability - are all intrinsic to GX. Add contemporary styling, multiple input/output options, light weight, and advanced protection circuitry, and the GX Series clearly represents real value - something everyone can use.
GX amplifiers deliver just the right amount of power to the most popular speakers used by entertainers. Typically, 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 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. It is ideal for speakers in the 300W range.

Took about ten minutes of talking with the sales engineer to figure out what I needed to fix old audio equipment in one of our business buildings. He was very informative and knowledgeable, didnt misinform me or try to sell me other bs that I didnt need. 5/5 will recommend this product and company for a spot on job at selling quality over quantity.
