The Lexicon DD-8 is a multiroom amplifier featuring eight channels in a small form factor.


The Lexicon DD-8 delivers 125 watts into each of its eight channels, yet measures just 1.7 inches high (one rack space) x 17.3 inches wide x 14.9 inches deep and weighs only 9.2lbs.

Harman’s new DriveCore amplifier IC chip, which was co-developed with Texas Instruments Inc. exclusively for Harman, incorporates component integration into an IC that is smaller than a postage stamp.

“With the release of the DD-8, Lexicon establishes an entirely new design paradigm for consumer amplifiers,” noted Jim Garrett, market manager, Harman High Performance AV. “DriveCore technology advances amplifier design on several significant levels — smaller size, lighter weight, greater efficiency, more environmentally friendly manufacturing – and better sound. Thanks to its many advantages, Harman is also incorporating DriveCore into its automotive and pro audio products.”

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 and heat production are reduced, making the DD-8 much more energy efficient than typical amplifiers and eliminating the need for a fan, the company said. According to Harman, the DriveCore design also yields sonic benefits, thanks to tighter tolerances, better circuit matching and inherently lower noise.

The Lexicon DD-8 is intended for multiroom audio, custom installation, and home theater. It comes with Phoenix speaker connectors and offers flexible configuration options, including bus inputs and outputs, local-channel inputs, and mono/stereo selection for each channel output pair. The DD-8 features independent output level adjustment for each channel, as well as 5-15VDC trigger control ports. The DD-8 complies with the new half-watt standby power consumption standards, and uses less power during normal operation than most traditional amplifiers do at idle. The amplifier has feedback and protection circuits incorporated into the DriveCore chip, and will switch to low-power standby mode when not in use for even lower energy consumption.

The Lexicon DD-8 Multi-Room Amplifier is available at a suggested retail price of $2,500.
