The GX7 professional power amplifier continues in the tradition of QSC's top-selling GX Series professional power amplifiers by offering an attractive combination of power, fidelity, configurability, long-term reliability, and overall value. At the heart of the GX7 is an all-new, advanced power supply based on the road-proven PowerLight Series technology. The result is a more overall power output in a lightweight casing compared to previous GX models—without any sacrifice in audio quality. At 1000W per channel at 4 ohms, the GX7 provides more than ample power to connect up to four 500W 15" 2-way speakers or two 1000W subwoofers at a time. This will help to keep your overall system cost down while still maintaining maximum performance levels. The 8 ohm output is 725 watts per channel which yields considerable headroom and increased dynamic range for today's popular loudspeakers.
