Get An Ultra Efficient One Piece Audio Amp With The Crown Audio CT475 Comtech Drivecore 4 x 75W Install Amplifier

With a name synonymous with powerful, reliable performance, the Crown Audio ComTech DriveCore family of amplifiers firmly establishes new standards in innovation. Performance is exemplary in every respect with Signal-to-Noise of better than 110dB and Total Harmonic Distortion below 0.05% across the full audio bandwidth, delivering studio-grade sound in one rack-space with up to 8 channels of 125W. ComTech DriveCore is ideal for installations that require premium sound quality, multi-channel configurations, compact dimensions, and quite often zero ambient fan noise. Typical applications include boardrooms, video and teleconferencing, VIP suites in stadiums and arenas, and upscale restaurants and retail outlets to name just a few. Representing next generation technology available today, the Crown ComTech DriveCore proves without a doubt that big things really do come in small packages.

Powering this remarkable amplifier is the pioneering technology of DriveCore, which seamlessly integrates the amplifier drive stage into the power output stage fusing everything into a chip the size of a dime. The foundational DriveCore circuitry is based on breakthroughs by Crown's own Gerald Stanley with five patents applying to the advanced feedback, modulation and output stage technologies. DriveCore's front-end drive circuits leverage the inherent efficiency of Class D output stages while also maintaining superb sonic characteristics. The end result is an ultra-efficient one-piece audio amplifier circuit that exhibits the exemplary audio quality of a highly evolved Class AB design.

Energy efficiency is an integral part of Crown ComTech DriveCore. This series debuts a new four-stage universal power supply that adapts to operating demands to assure peak efficiency. Normal, Green, Sleep, and Deep Sleep modes combine to provide everything from full voltage to the supply rails for instant response to limiting power consumption, to less than 1W when not in use. And, because it's over 90% efficient in the DriveCore stage, no fan is required, allowing for ultra-quiet operation.
