QSC GXD 8

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. The power levels of the GXD amplifiers are matched to the most popular loudspeakers: GXD 8, per channel – 800 W into 8 Ω, and 1200 W into 4 Ω (4500 W peak). The Class-D amplifier topology is very efficient, making the GXD amplifiers small and light. In addition the Universal Power Supply used in the GXD helps to reduce weight. The GXD 8 comes in a handy 2U package with a depth of only 229 mm and a weight of  5.9 kg. 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. The GXD 9 has intergrated complete loudspeaker processing; Channel Gain & Polarity, 4th Order Linkwitz Riley Highpass and Lowpass Filters, 4-band Parametric EQ, 50 mSec of Alignment Delay and QSC Smart Speaker Protection limiters.
