QSC GX5 Power Amplifier 700W/ch
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.
The GX5
power amp uses a Class H system based on key elements of the PLX Series
almost doubling power in the same size and weight. QSC design expertise
allows the output devices to shift from low-power to high-power rails
in less than a millionth of a second ensuring that the output power is
always right where it needs to be without excess loss.
