Description
DriveCore Technology
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. More information about DriveCore™.
Energy Efficiency
Energy efficiency is an integral part of 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.
It's Time to Go Small
An ideal complement for the intimate spaces within a larger project, such as the high-end suites in a stadium, the ComTech DriveCore™ is a technological marvel. Small in size, big in performance, and competitively priced, it effortlessly demonstrates Crown's unmistakable command of installed sound applications.
