The 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.
\nAs always, GX Series amplifiers are fully protected from the usual hazards of the trade, ensuring stable performance and long life.<\/p>\n
GX Series amplifiers are ideal for professional entertainers who require maximum performance and portability on a limited budget. The hallmarks of the QSC brand \u2013 professional audio quality, meticulous engineering, precision manufacturing, and long-term reliability – are all intrinsic to GX. Add contemporary styling, multiple input\/output options, and lightweight, and advanced protection circuitry, and the GX Series clearly represents real value \u2013 something everyone can use. GX amplifiers deliver just the right amount of power to the most popular speakers used by entertainers. Typically, loudspeaker manufacturers recommend an amplifier with a power output equal to the speaker\u2019s \u201cProgram (Music) Power\u201d rating or two times (2 x) the \u201cContinuous (RMS) Power\u201d rating.<\/p>\n
The GX3 is ideal for speakers in the 300-watt (Program) range, while the GX5 provides full performance for 500-watt (Program) speakers. The GX7 outputs 725 watts into an 8-ohm load.
\nOwners of popular 4-ohm loudspeakers (such as dual-woofer, two-way models) will find the 700-watt (4 ohms) power of the GX5 an ideal match while the GX7 1000 watts will very capably power many of today\u2019s popular subwoofers or two typical 8-ohm speakers per channel.<\/p>\n
Technical Notes<\/strong><\/p>\n GuardRail\u2122 Subwoofer\/Satellite Crossover
\nGuardRail 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.<\/p>\n
\nA 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.<\/p>\n","protected":false},"excerpt":{"rendered":"\n
