QSC Amplifier GX3

Engineered to fulfill the practical demands of mobile performers, this lightweight amplifier line provides power levels optimized directly for the market\’s most common entertainment speakers. It ensures maximum real-world headroom for 4-ohm and 8-ohm loads, accepting any audio source via its array of XLR, 1/4-inch TRS, and phono inputs. Loudspeaker connections are made easy using either traditional binding posts or the integrated Speakon® combo jack, which accepts standard 1/4-inch TS or 2- and 4-pole Speakon plugs (driving 2 poles only). The physical footprint is kept strictly minimal, employing a shallow 10.1-inch (257 mm) depth to fit into budget-friendly, portable gear racks. Despite its rugged capabilities, the lineup is easy to transport—the GX3 and GX5 weigh less than 26 lbs (12.5 kg), and the specialized GX7 weighs only 15.5 lbs (7 kg). System adjustments remain accurate thanks to detented gain dials, an onboard subwoofer/satellite crossover network, and front-panel status LEDs. To keep your system running safely, built-in GuardRail™ protection automatically regulates overheating and overdrive, preventing equipment damage without dropping the audio mid-event.
