The Powertech  Series is a high performance line of amplifiers designed exclusively for the touring and live sound professional. Four models range in power from 1200 watts to 2250 watts per channel, all in two-rack space chassis that are only 14" deep and 21 lbs.

With PowerWave technology, PowerTech amplifiers take your sound to a whole new level. Not only does it give you tighter bass and clean transparent highs, PowerWave also cuts waste heat, boosts reliability and gets rid of unwanted noise and hum. PowerWave is a revolutionary switching power supply technology that provides ample current to the audio power circuitry by charging the supply rails 230,000 times a second through an ultra-low impedance circuit. So unlike amplifiers that use conventional supplies, the audio signal is never starved prematurely and remains crisp and clean.
