DCA Series

Built on a rugged tour-grade chassis, DCA 2-channel and 4-channel amps deliver heavyweight power in a light 2RU package. All models are equipped with our innovative DataPort interface, which facilitates a fast hook-up, enables control and monitoring via Q-SYS, and supports a range of useful accessories.

All are safeguarded by protective circuitry that keeps them going strong over the long haul.

Using a standard VGA-style connector that simplifies wiring and speeds up installation, the DCA DataPort interface provides single-cable integration with DCP, DXP, DCM and Q-SYS. Creating a smart, centrally controlled system that goes beyond simple audio connections, DataPort enables DSP crossovers, speaker-specific EQ, and monitoring and control of amplifier and loudspeaker functions.

A single DataPort connection includes two channels of audio, output voltage monitoring (VMON), current monitoring (IMON), clip/protect monitoring, and thermal monitoring. DataPort also enables AC standby control and provides a 15 volt DC power supply for rear-panel accessories.

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. This Ultra-fast charging of supply rails results in tighter bass and clean, transparent highs. 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
• Stereo, parallel, and bridged mono operation
• Extensive protection circuitry guarding against failures such as DC, infrasonic, thermal overload, and short circuits.
• Active Inrush Limiting allowing the amps to be turned on and off safely without expensive AC power sequencers
