GX5 amplifier delivers just the right amount of power to the most popular speakers used by entertainers. The GX5 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. The GX5 provides full performance for 500 watt (Program) speakers.
