With a name synonymous with powerful, reliable performance, the 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 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. More

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.
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.
