Maximum performance and portability with very flexible I/O.

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.

QSC GX5 Stereo Power Amplifier Features:

• Power levels matched to the most popular speakers used by entertainers
• Optimized for maximum real-world headroom into 4Ω and 8Ω speaker systems
