The QSC GSX GX5 Power Amplifier is designed to provide power, portability and professional sound quality at an affordable price. The GX5 features 500 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 GX5 is a feature packed, lightweight amplifier that's suitable for mid-size venue installation, musicians, mobile DJs, etc.
