Do you need a high powered, low-priced amp with professional performance while also being light in weight? Look no further than the QSC GX7 Power Amplifier! Like all QSC power amps, the GX7 was built to deliver professional audio quality, meticulous engineering, precision manufacturing and long-term reliability. Add contemporary styling, multiple input/output options, extreme light weight (only 15.5 lbs!), and advanced protection circuitry, and the QSC GX7 clearly represents real value! QSC GX7 Stereo Power Amplifier Features
Power levels matched to the most popular speakers used by entertainersOptimized for maximum real-world headroom into 4 ohm and 8 ohm speaker systems Versatile XLR, 1/4 inch TRS and phono input connectors for compatibility with any sourceSpeakon combo outputs accept 1/4 inch TS plugs or Speakon 2-pole and 4-pole plugsBinding posts support all other speaker wiring systemsLoads of power and it still only weighs 15.5 poundsThe GX7 amplifier is powerful enough to handle most PA speakers on the market. Typically, loudspeaker manufacturers recommend an amplifier with power output equal to the speaker's Program (Music) Power rating or two times (2 x) the Continuous (RMS) Power rating. The GX7 outputs 725 watts into an 8 ohm load. Owners of popular 4 ohm loudspeakers (such as dual-woofer, two-way models) will find the 700 watt (4 ohm) power of the GX5 an ideal match while the GX7's 1000 watts will very capably power many of today's popular subwoofers or two typical 8 ohm speakers per channel. The QSC GX7 adds the road-proven PowerLight supply to the Class H output section, for more overall output power and additional weight savings. The result is one of the highest power-to-weight ratios in the industry. A low-noise variable-speed fan with rear-to-front airflow keeps amplifiers and racks cool. As always, GX Series amplifiers are fully protected from the usual hazards of the trade, ensuring stable performance and long life. GuardRail 
GuardRail protection delivers full peak power while preventing detrimental overloads. During excessive clipping, or extreme overheating, GuardRail reduces gain just enough to preserve the integrity of the music, protect the speakers and keep the audience excited, without unprofessional distortion levels or shutdowns.Subwoofer/Satellite Crossover 
A subwoofer reduces strain on the full-range speaker, allowing it to play louder, or letting a smaller speaker do the same job. The GX Series supports this mode with a Crossover switch that splits the full-range input entering Ch 1, sending 20 Hz -100 Hz to the sub (Ch 1) and 100 Hz - 20 kHz to the top box (Ch 2). The front panel gain controls balance the sub and top box, while GuardRail optimizes peak power into the sub and top individually, for greater musical impact and dynamic range.
