Crystal-clear, seat-shaking cinema sound is here with our DCA Series Digital Cinema Amplifiers. Five 21 lb (9.5kg), two rack space models offer power points from 200 to 1700W 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, we’ve packed these amplifiers with useful features and every input/output connector you’ll ever need. With PowerLight technology, DCA amplifiers take 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.
