About the QSC GX3: Power Amplifier

GX-series Amplifiers are ideal for professional entertainers who require maximum performance and portability on a limited budget.  QSC designers, headed by Pat Quilter, have optimized output and appearance while reducing raw material cost and weight.  It's all here – dramatic styling, easy hookup and adjustments, excellent audio quality and QSC reliability.

GX Amplifiers deliver just the right amount of Power to the most popular speakers used by entertainers.  Most loudspeaker manufacturers recommend an Amplifier including a Power output equal to the speaker's "program (music) Power" rating or two times the "continuous (RMS) Power" rating.

The GX3 is ideal for speakers in the 300 W (program) range, while the GX5 provides full performance for 500 W (program) speakers.  Both models supply maximum possible Power to 4 ohm and 8 ohm loads.  Owners of popular 4 ohm loudspeakers (dual-woofer, two-way models and many subwoofers) will find the 700 W (4 ohm) Power of the GX5 an ideal match.
