ComTech DriveCore amplifiers are stable for 2 to 16ohms loads. Flexible input routing. 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. 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.
