Companies Demonstrate First All-Digital Loudspeaker Technology at CES

Avio Digital's MediaWire home network technology provides connectivity and interoperability, enabling systems to share multimedia data and control over standard home wiring at speeds of up to 100 Mbps. Apogee Technology's DDX® all-digital amplifiers allow direct conversion of network audio into speaker power. With Huff Loudspeaker's revolutionary driver design and direct drive provided by digital crossovers, consumers will hear uncompromised audio reproduction.

Along with its partners, Avio Digital will be demonstrating a variety of multimedia home networking technology solutions at the Consumer Electronics Show (CES) 2000 in Las Vegas, NV. MediaWire's ability to distribute high-quality digital audio throughout the home is the public focus of this CES network.

``Avio Digital is pleased that two of the most respected innovators in audio technology have embraced the capabilities of MediaWire,'' said Penny Johnson, director of marketing at Avio Digital, Inc. ``With MediaWire as the bridge between audio and other devices, users will now be able to experience high-quality multimedia and music throughout the home, regardless of its source.''

About MediaWire

The bandwidth of the MediaWire home network (up to 100 Mbps in the first-generation product) enables a single cable or telephone line to simultaneously deliver thirty-two 24-bit audio channels, eight MPEG-2 video channels (6 Mbps each), sixteen phone or ISDN lines and over 12 Mbps of serial control or TCP/IP (Internet) data. Using MediaWire home network technology, one connector provides all these services.

Avio Digital plans to broadly license the MediaWire home network technology to consumer electronics, cable/telecom, and PC manufacturers and develop MediaWire-enhanced products. Customer delivery of silicon is expected in the 2nd quarter of 2000 at an anticipated volume price of under $10.

MediaWire was originally conceived at Interval Research Corporation (Palo Alto, CA) -- Avio Digital is an Interval spin-out company chartered with the ongoing commercial development, deployment and marketing of the MediaWire technology.

Digital media is distributed by the MediaWire home with a range of 33 meters (over 100 feet) between devices using standard Category 3 telephone wiring, or 400 meters between devices using coax. With the ability to connect up to 100 devices of different types, the MediaWire home network is capable of supporting a total cable length of more than 4,000 meters (about 2.5 miles).

Huff Loudspeaker Co.

Using the world's finest drivers and filters, Huff Loudspeaker Co. is integrating new technologies at the forefront of high-end speaker design and manufacturing. After studying E.E. at Georgia Tech, design leader John Huff became a Warner Bros. recording artist, producer, studio musician, and engineer.

He has spent 20 years listening to music live, then immediately through the playback system after recording, gaining experience at detecting the coloration induced by audio systems, much of which comes from the speakers. This has resulted in several unique speaker technologies. The System Three Omnidirectional and the System One Ceramic/Ribbon are regarded as two of the most accurate speakers available at any price.
