QSC GX3

GX Series amplifiers are 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.

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