QSC GX5 Stereo Power AmplifierThe 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.
