QSC GXD4 Amp

The GXD Class-D amplifiers have been engineered for high performance output and optimized for maximum real-world headroom into 4 Ω and 8 Ω loudspeaker systems. In addition the Universal Power Supply used in the GXD helps to reduce weight. Both amplifiers are 2RU and are only 229 mm (9 inches) deep. The GXD 4 weighs in at 5.1 kg (11 lbs), the GXD 8 is at 5.9 kg (13 lbs). The GXD amplifiers have an LCD for control and monitoring, with three buttons for menu navigation, and two knobs for adjusting parameters. There are 18 User Presets that can be edited, stored and recalled to match any configuration or system Each channel has parallel XLR and ¼” TRS connectors for inputs. The outputs are professional NL4 and binding post connectors for mono and bi-amp speaker connectivity.
