More about Crown's DCi DriveCore Power Amplifiers
From meeting rooms to massive stadiums, save time with the streamlined and highly efficient DCi series. Ideal for analog or network installations, DCi is great for system integrators looking for amping solutions that are quick to configure, simple to use, and deliver reliable, uncompromising signal-to-noise performance. And, with its “minimum size, maximum power” design, DCi features a compact, lightweight build that makes it easy to install even in cramped quarters.
With DCi, it’s what’s inside that counts. Front-end drive circuits put Class D output stage efficiency to good use to yield superb sonic characteristics. The “DC” of DCi stands for DriveCore® technology, which utilizes patented feedback and PWM circuits to deliver fast recovery on peak transients, accurate reproduction of low-level details, and precise tracking of low frequencies at all power levels. DCi also boasts a proprietary hybrid analog-digital circuit.
