HARMAN’s Crown Showcases ComTech DriveCore™ Series Amplifiers At InfoComm 2011

ORLANDO, Florida — Underscoring the transformative capabilities of HARMAN Crown’s chip-based technology, the company today placed a central emphasis on its ComTech DriveCore™ Series Amplifiers at InfoComm 2011. The technology enables performance grade amplifiers to provide a smaller footprint for enhanced power in a range of fixed installations including executive boardrooms, education facilities, and luxury suites in hotels and stadiums.

The line, which consists of four models, offering up to eight channels at 150 watts per channel, are all one rack, fan-less and ultra-energy efficient. DriveCore chip technology offers greater than 90 percent efficiency with no compromise in performance, boasting a signal-to-noise ratio of 110dB. DriveCore also has patented feedback and protection circuits integrated into the silicon for fast and accurate response.

“Never before has there been an amplifier that systems integration professionals could look to as being specifically designed for smaller fixed installation environments,” said Marc Kellom, director of marketing for Crown. “We not only forever changed the way amplifiers will be engineered with our DriveCore chip technology but we also answered the call of our customers to design an amplifier that would meet the specific needs of projects that are a major aspect of their business.”

The DriveCore chip, which was co-developed with Texas Instruments, combines the amplifier drive stage into the power output stage (along with additional audio-signal functions) – circuits that are typically much larger in size and power requirements. As a result, power consumption is dramatically reduced, and the amplifiers are much more energy-efficient. The DriveCore design yields sonic benefits as well, thanks to tighter tolerances, better circuit matching and inherently lower noise.

Because of their greater efficiency and Class D design, ComTech DriveCore series amplifiers also produce less heat, a by-product of inefficient amplifier operation. As a result, the amplifiers do not need to use a fan or traditional large, heavy heat sinks, further reducing energy demands.
