Q-SYS DCA2422 2-Channel Digital Cinema Audio Amplifier

Crystal-clear, seat-shaking cinema sound is here with our DCA Series Digital Cinema Amplifiers. Five 21 lb (9.5 kg), two rack space models offer power points from 200 to 1700 watts per channel. With QSC’s exclusive PowerLight™ switching technology, you’ll experience ultra-powerful bass and superior highs in every action scene. Alongside superior performance, these amplifiers include useful features and a variety of input/output connectors to meet all installation needs.

PowerLight technology elevates DCA amplifiers, delivering dynamic soundtracks with bigger bass and cleaner highs while reducing wasted heat and boosting reliability. PowerLight is a switching power supply that charges the supply rails 230,000 times per second via an ultra-low impedance circuit, ensuring the audio signal stays crisp and clear without premature drop-off, unlike conventional high-powered amplifiers.

DCA Series amplifiers also feature selectable clip limiters, subsonic filters, and multiple operational modes including stereo, parallel, and bridged-mono. They are equipped with XLR, 1/4” TRS, and detachable terminal block input connectors, with outputs available on both Neutrik Speakon® and safety-shrouded barrier strips.

With five models, the DCA Series offers a solution for every application. For example, the DCA1222 is ideal for surround applications with extra low impedance capability, driving 1.6 ohms per channel, while the DCA3422, with 1250 watts per channel at 4 ohms, is optimized for powering subwoofer systems.
