QSC DCA 3422 Description

DCA 3422 - 2U Rack Mount Power Amp 2 x 1100 W

Crystal-clear, breathtaking, seat-shaking cinema sound is here with our DCA Series Digital Cinema Amplifiers. Five 2-channel and two 4-channel models offer power points from 200 to 1700 watts per channel in a two rack, 21-pound amplifier. With QSC's exclusive PowerWave switching technology you'll hear ultra-powerful bass and superior highs in every scene.

With technology, DCA amplifiers take your soundtracks to a whole new level. Not only does it give your music bigger bass and cleaner highs, PowerWave also cuts wasted heat and boosts reliability. PowerWave is a switching power supply 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 high-powered amps with conventional supplies, the audio signal is never starved prematurely, but remains crisp and clean. It virtually eliminates hum and greatly reduces noise, providing a vast dynamic range that can handle the most demanding digital soundtracks without running out of headroom. DCA Series amps also boast a set of useful features such as individually selectable clip limiters and subsonic filters; and stereo, parallel, and bridged mono operation.
