Traditional Pitfalls of Audio Radio Frequency Technologies Avoided with New Technology

Digital Harmony intends to sell and license WireFree modules and designs to leading speaker manufacturers. A preview of this breakthrough new technology will be demonstrated at the Digital Harmony Technologies booth LVCC No. 2327 at the Consumer Electronics Show (CES) in Las Vegas, January 6th through 9th, 2000.

Wireless speaker solutions based on various radio frequency (RF) standards have been available to consumers for some time. However, most suffer from quality issues due to the inherent limitations of existing RF technology. The most common limitation is reliable sound quality, since magnetic fields -- from microwave ovens to the minor fields created when a human walks by a speaker -- disturb and distort radio transmissions, resulting in speaker crackling and, at worst, a complete loss of transmission. In addition, the FCC's recent allocation of UHF channels 60 through 69 to support digital TV will eliminate this spectrum from previously introduced RF speaker systems. Digital Harmony's WireFree technology does not suffer from these limitations.

``WireFree finally overcomes the biggest drawback of today's wireless audio technologies -- reliable sound quality,'' said the president and CEO of Digital Harmony, Greg Bartlett. ``Consumers purchasing high-end audio systems refuse to accept the limitations of today's wireless systems. Digital Harmony now can help manufacturers virtually eliminate these issues for next-generation speaker systems.''

The WireFree system transfers, securely and reliably, eight channels of CD-quality audio data at a rate of ten megabits per second. WireFree speakers can be placed more than 60 feet from an audio source, which is especially beneficial for rear speakers in home theater environments. Upcoming modules are being designed to work seamlessly with Digital Harmony's DHIVA(TM) interface modules, used to interconnect audio/video devices using the IEEE 1394 high-speed interface.

The world's first 1394-compliant wireless speaker system, designed and manufactured by Music Sciences Inc., will be showcased as part of the Digital Harmony Reference System 2000(TM), a multi-vendor system of 1394-compliant home entertainment devices. Music Sciences' digital WireFree wall speakers include 24-bit, 96kHz converters, digital equalization, and patent-pending phase-matrix time alignment. The system includes a Cinema 501 subwoofer with an integrated Digital Harmony DHIVA 1394 interface module.

For new and existing home entertainment systems, Digital Harmony technology guarantees cross-manufacturer interoperability, provides easy system set-up and control, and delivers reliable, high-quality audio and video in single- or multiple-room environments.

``Through years of advanced R&D, we have finally designed a wireless technology that meets the high expectations of audiophiles,'' said Don Wadia Moses, co-inventor of the technology and president of Music Sciences. ``Speaker cables running across the floor are not only ugly, they are abhorred by most people I know.''
