The latest advances in sound system technology such as Dolby Digital Surround-EX and tri-amplification require more amplifier channels than ever before. That’s why we designed our newest DCA amplifiers to give you four channels of power in a compact package that doesn’t eat up precious rack space. And, compared to the cost of two stereo amplifiers, you’ll find they leave more room in your budget as well. In addition to their superior performance we’ve packed these amps with useful features designed specifically for the cinema market.
QSC DCA1644 Amplifer
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.
