GX Series amplifiers are ideal for professional entertainers who require maximum performance and portability on a limited budget. The hallmarks of the QSC brand - professional audio quality meticulous engineering precision manufacturing and long-term reliability - are all intrinsic to GX. Add contemporary styling multiple input/output options light weight and advanced protection circuitry and the GX Series clearly represents real value - something everyone can use.
GX amplifiers deliver just the right amount of power to the most popular speakers used by entertainers. Typically loudspeaker manufacturers recommend an amplifier with power output equal to the speaker's Program (Music) Power rating or two times (2 x) the Continuous (RMS) Power rating.
The GX3 is ideal for speakers in the 300 watt (Program) range while the GX5 provides full performance for 500 watt (Program) speakers.
The GX5 uses a Class H system based on key elements of the PL Series (PLX PL3 CX DCA) 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 uses premium toroidal power transformers for reliable mid-weight performance. A variable-speed fan moves air crosswise through the amplifier drawing cool air in over the power transformer through the fan and then over the heat sink. This keeps the transformer cool and allows a full size heat sink to fit in a down-sized chassis.
As always GX Series amplifiers are fully protected from the usual hazards of the trade ensuring stable performance and long life.
