PlayStation Application Further Strengthens Tripath's Expansion In the Integrated Home Entertainment Market Segment

Tripath's digital amplifier technology enabled Sony to incorporate six, high-powered amplifiers into a module small enough to be contained in the subwoofer speaker cabinet, eliminating the need for a separate audio/video amplifier. With two optical and two analog inputs, Dolby Digital®/DTS® (Digital Theater Systems) decoding and Sony's ``Digital Cinema Sound,'' the SA-PSD5 can also connect directly to standard DVD players to provide a powerful home theater experience. The lack of significant heat dissipation from the Tripath amplifiers allowed Sony to deliver this performance inside the one-foot cube sized subwoofer. Combined with five compact satellite speakers this system offers a unique combination of power, fidelity and size for owners of the 10 million PS2 systems that have been shipped to date and consumers upgrading their DVD systems to Dolby Digital 5.1 Surround Sound. The SA-PSD5 was recently announced in Japan and will available in stores there on April 21.

``Tripath's efficient, 1-bit digital amplifiers were the key to integrating Sony's sound processing and 5.1 audio channels delivering 330W of power into the sub woofer cabinet. This compact and powerful surround sound system will compliment the PlayStation 2's real life graphics with an equally impressive audio experience,'' said Mr. Masahiro Tamura, General Manager Audio Entertainment Group, Sony Corporation.

``Once again Sony has created a truly innovative product that not only increases their leadership in game entertainment systems with PlayStation 2 but also provides an attractive, compact, Dolby Digital 5.1, home theater system to compliment standard DVD players. Tripath is delighted Sony selected our Class-T digital amplifiers to deliver the high fidelity sound experience Sony customers expect,'' said Dr. Adya Tripathi, president and CEO of Tripath.

The Sony system uses the new Tripath TA-2022 Class-T, stereo, digital amplifier. Its patented Class-T digital architecture delivers up to 100W of power per channel in a single integrated package. Achieving less than 0.1% total harmonic distortion at 90W with greater than 90% efficiency, the TA 2022 provides the power, fidelity and compact size for new integrated home entertainment systems. By not wasting power these amplifiers minimize heat sinks and reduce the size and cost of power supplies to the point where the audio power amplifier function can be integrated with other elements of home entertainment systems.
