The DCA 2422 is a DCA series digital cinema amplifier gives crystal-clear, breathtaking, seat-shaking cinema sound. Offer power points from 200 to 1700W per channel in a 2-rack, 21 pound amplifier. With QSC’s exclusive PowerLight switching technology you’ll hear ultra-powerful bass and superior highs in every scene. With PowerLight technology, DCA amplifiers take your soundtracks to a whole new level. Not only does it give your music 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 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.
