The Lexicon DD-8 redefines the state-of-the-art multi-room distributed audio applications. Taking advantage of HARMAN’s pioneering DriveCore amplifier technology, the DD-8 delivers eight channels of 125W each from a chassis only 1U high. The revolutionary DriveCore circuit integrates the amplifier drive stage with the power output stage on a compact chip. Five patents apply to the advanced feedback, modulation and output stage technologies. DriveCore’s front-end drive circuits utilise the inherent efficiencies of Class D amplification while delivering the audiophile performance of advanced A/B designs.

The 90%+ efficiency of the DriveCore stage means that the DD8 operates at a low temperature without a fan meaning that your equipment racks stay cool and ultra-quiet. In fact as many as five DD8s may be ‘flat stacked’ without requring spacing. The DD-8 was designed with future eco power regulations in mind, and uses less power during full operation than many amplifiers do in standby. It delivers a full-complement of control features as well, including local and bus inputs, stereo/mono selection, channel output level controls and system triggers.
