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.
