QSC GX5 Stereo Power Amplifier
The QSC GX5 Stereo Power Amplifier is 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 of the rackmountable GX5 while reducing raw material cost and weight. The GX5 power amplifier provides full performance for 500 watt (Program) speakers and supplies 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 watt (4 ohm) power of the GX5 an ideal match.
