GX Series amplifiers are 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 while reducing raw material cost and weight. It's all here – dramatic styling, easy hookup and adjustments, excellent audio quality and QSC reliability.

 

The QSC GSX GX3 Power Amplifier is designed to provide power, portability and professional sound quality at an affordable price. The GX3 features 300 watts of power at 8 ohms (both channels driven) in a design that's easy to install and delivers flexible features. The rear panel features balanced XLR and 1/4" phone inputs, as well as unbalanced RCA phono inputs for complete compatibility with professional and consumer audio gear.

The outputs feature speaker binding posts and Speakon® connections. Detented gain controls provide precise level settings. QSC's GuardRail protection delivers full peak power while preventing detrimental overloads due to excessive clipping or overheating. In addition, a built-in 180Hz crossover splits low and mid frequency signal between the left and right channel. This is ideal for driving sub-woofers. The GX3 is a feature packed, lightweight amplifier that's suitable for mid-size venue installation, musicians, mobile DJs, etc.
