Product Description

GX Series amplifiers are ideal for professional entertainers who require maximum performance and portability on a limited budget. The hallmarks of the QSC brand - professional audio quality, meticulous engineering, precision manufacturing and long-term reliability - are all intrinsic to GX. Add contemporary styling, multiple input/output options, light weight, and advanced protection circuitry, and the GX Series clearly represents real value - 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 power output equal to the speaker's Program (Music) Power rating or two times (2 x) the Continuous (RMS) Power rating.

The GX7's 1000 watts will very capably power many of today's popular subwoofers or two typical 8 ohm speakers per channel.

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.

As always, GX Series amplifiers are fully protected from the usual hazards of the trade, ensuring stable performance and long life.

GuardRail(TM)

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. GuardRail optimizes peak power into the sub and top individually, for greater musical impact and dynamic range. zZounds is an authorized dealer of QSC products.

zZounds has verified that this customer bought this product from us. "Just buy the thing, no substitutes!! Don't hesitate!!!"
Sound: Good sound, being a mobile DJ play all types of music! Has a real full sound. Upgraded from a Behringer EPQ2000 was not real happy with the sound. Kind of muddy, plugged the QSC in, perfect, had to adjust the eq. Love the amp!! Feature: Real easy to hook up whatever you got. 1/4" speaker to speaker, got it. Any combination it's probably there. Ease of Use: It is easy to use, plug and go!!! No worries Quality: Built real tough, ready for the road!!! Value: Hell, $100.00 a year, is your gear worth that?? Manufacturer Support: 6 year warranty, nuff said The Wow Factor: perfect fit in my rack, no worries Overall: This is "The AMP" don't kid yourself. I started with the Behringer for the price. Had to buy new diaphragms and woofers, due to blowing them. Ran just as hard on the QSC no problems. Differences in machines. Plus 6 year warranty all good.
Style of Music: All types

zZounds offers a number of different installment payment plans that make it affordable and convenient for you to get the gear you really want today, without racking up risky credit card debt.

Other stores offer house credit cards that require you to fill out an application and pass a credit check--and, if you qualify, leave you vulnerable to exorbitant interest charges once the initial promotional period ends. zZounds payment plans are easy to get and simple to use; plus we'll never charge you interest!
