Crown Audio ComTech Drive Core series amplifiers are among a new generation of products included in Harman International's GreenEdge environmental initiative. Crown DriveCore series amplifiers are designed to be energy-efficient and use fewer resources in manufacturing.
At the heart of the amplifiers is Harman's new DriveCore amplifier IC chip. This chip, co-developed by with Texas Instruments, incorporates a new level of component integration into an IC that is smaller than the size of a postage stamp. Harman supplied the amplifier expertise, while TI provided the high-voltage process technology.
The DriveCore chip 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 reduced. The DriveCore is designed for sonic benefits as well, including tighter tolerances, better circuit matching and lower noise. The use of fewer internal components also means reduced strain on environmental resources from raw materials usage and manufacturing processes.
ComTech DriveCore series amplifiers also produce less heat. They do not need to use a fan and also reduce energy demands for cooling.
The four models in the Crown ComTech DriveCore series deliver output with greater than 90 percent efficiency, yet are compact and weigh less than 10 lbs. This reduced weight means lower shipping and fuel costs when transporting the amplifiers.
The amplifiers' Green Mode technology also automatically adjusts their operating level according to the input signal, and places the amplifiers into either Sleep or Deep Sleep Mode after an extended absence of input signal.
