Q-SYS DCA3022 2-Channel Digital Cinema Audio Amplifier

Crystal-clear, seat-shaking cinema sound is here with the DCA Series Digital Cinema Amplifiers. Five 21 lb (9.5kg), two rack space models offer power points from 200 to 1700 watts per channel. With QSC’s exclusive PowerLight™ switching technology you’ll hear ultra powerful bass and superior highs in every action scene. In addition to their superior performance, QSC packed these amplifiers with useful features and every input/output connector you’ll ever need.

With PowerLight technology, the Q-SYS DCA3022 DCA amplifier takes your soundtracks to a whole new level. Not only does it give your movies bigger bass and cleaner highs, PowerLight also cuts wasted heat and boosts reliability. PowerLight 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 amplifiers with conventional supplies, the audio signal is never starved prematurely, but remains crisp and clean.

DCA Series amplifiers like the Q-SYS DCA3022 also boast a set of useful features such as individually selectable clip limiters, subsonic filters and stereo, parallel, and bridged-mono operation. The amplifiers feature XLR, 1/4” TRS, and detachable terminal block input connectors, and outputs are both Neutrik Speakon® and safety shrouded barrier strips.
