ComTech DriveCore CT 4150 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 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.
