The QSC GX7 Power Amplifier - 725 Watts delivers just the right amount of power for the most popular speakers being produced today!

The GX series of amplifiers have been designed to offer maximum performance, reliability, and portability. Superb engineering and manufacturing along with the QSC name gives you everything your looking for in your amp. The GX7 offers the abiity to power two 8 ohm typical speakers with 725 watts @8 ohms, or power many of today's subwoofers with 1000 watts @ 4 ohms. Qsc includes the PowerLight supply to the class H output section. Allowing for more output power  and less weight. A variable speed fan, keeps it cool with a rear-to-front airflow circulation. QSC also has their GuardRailĂ– protection. This is a feature that will reduce the gain just enough when it senses overloading to save the speaker, but not take away from the overall sound. If you running it with a main speaker and subwoofer, they give you a crossover feature that directs the higher frequencies to your main speaker, and the lower ones to the subwoofer.
