QSC GX3 Power Amplifier (300W @ 8ohms)

Professional entertainers on a budget no longer need to compromise on audio quality with QSC's GX3 amplifier, which brings the brand's renowned engineering excellence into an affordable, portable package. This 2RU powerhouse combines contemporary styling with multiple input/output options and advanced protection circuitry, making it an exceptional value proposition for serious performers. The GX3 utilises QSC's latest Grounded Collector output system alongside true Class B biasing, ensuring optimal cooling of power transistors while maintaining excellent thermal efficiency and audio performance.

Designed specifically for speakers in the 300-watt program range, the GX3 outputs 300W into 8 ohms with both channels driven, or 350W single channel. For 4-ohm loads, it provides 425W with both channels driven and 500W single channel. The amplifier maintains impressive specifications with distortion levels below 0.02% at 8 ohms and 0.05% at 4 ohms, plus a signal-to-noise ratio of 100dB across the 20Hz-20kHz frequency range.

Premium toroidal power transformers provide reliable mid-weight performance, while the variable-speed crosswise fan system draws cool air over the transformer and through the heat sink for optimal thermal management. Connectivity options include 3-pin XLR and 1/4" TRS balanced inputs on each channel, with Speakon®, 1/4" and binding post outputs. At just 12.1kg net weight and measuring 89mm x 483mm x 257mm, the GX3 offers professional-grade power in a compact, tour-ready chassis.
