QSC GX7 Power Amplifier 725 Watts/ch at 8 ohms

The latest addition to QSC's workhorse GX Series, the GX7 takes this compact, high-value class of pro PA amp to a whole new level. Engineered for real-world conditions encountered by professional entertainers, the GX amplifiers match their performance and features to the 4 ohm speaker systems found commonly on stages everywhere. The GX7's 1,000 watts per channel will drive 4 ohm subwoofers or a pair of typical 8 ohm speakers -- cleanly and effortlessly. All this from an amp that weighs a mere 15.5 lbs. and is only 3.5" high by 10.1" deep!

The GX7 features QSC's road-proven PowerLight power supply, delivering plenty of output without the excessive weight and high current consumption of other, less advanced amplifiers. Additionally, a Class H output design -- similar to that of QSC's famous PLX Series -- almost doubles power in the same form factor, compared to "old style" amps. QSC design expertise shifts the output devices from low-power to high-power rails in less than a millionth of a second, ensuring that the output power is always right where it needs to be without excess loss.

QSC's exclusive GuardRail™ protection system allows 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 show going -- without noticeable distortion levels or intrusive shutdowns. A low-noise variable-speed fan with rear-to-front airflow moves hot air out of the amp rack instead of pumping more of it inside.

All GX Series amplifiers feature comprehensive protection circuits that make these hard working road warriors immune to most abuse, gig after gig.

Rated 5 out of 5 by from Powerfully Nice Amp!I use this amp to push a pair of Yorkville LS808 subwoofers. It will literally bring down the house with bass power and doesn't even get warm. Will most definitely buy QSC amps in the future.
