Panasonic Chooses Tripath's 1-Bit Digital Audio Solution for High Power Professional Amplifier; TA3020 Powers 4-Channel, 800W Compact Professional Amplifier.

Business Editors/High-Tech Writers

Tripath Technology Inc. (Nasdaq:TRPH), creators of Digital Power Processing (DPP(R)), announced today that its Class-T(TM) advanced 1-bit digital audio amplifier has been chosen by Panasonic/ Matsushita Communication Industrial's (MCI) professional audio system brand, RAMSA (Research for Advanced Music Sound and Acoustics), for their new WP-D204 professional amplifier. Matsushita is best known for its Panasonic-brand of products.

Tripath's TA3020 1-bit digital audio amplifier device will enable a 4-channel x 200W (4 ohm) system in a compact 800W amplifier chassis. Due to an extraordinary light and thin chassis, multiple units of this product can be stacked on one another, which enables ease of system setup while saving space. By using the highly efficient Tripath TA3020 amplifier, which requires smaller power supplies and heat sinks than traditional amplifiers, RAMSA's new amplifier system provides clear sound, uses only half the energy consumption of a conventional professional amplifier, and allows for natural heat dissipation without a cooling fan.

Tripath's broad line of Class-T(TM) advanced 1-bit digital amplifiers are rapidly gaining market acceptance within high growth consumer electronics categories, such as home entertainment systems, DVD receivers, set-top boxes, personal computers, automotive head units, LCD TVs and flat panel displays. These tightly integrated Class-T(TM) based designs set a new standard for high power, exceptional sound quality and high efficiency. Panasonic/ Matsushita's RAMSA joins a list of other industry giants who have chosen Class-T(TM) as their digital amplifier technology such as Apex Digital, Fujitsu, Sony and Motorola.

"Panasonic/ Matsushita's choice is great news to Tripath, as we are expanding the adoption of our technology in professional applications as well as consumer products," said Dr. Adya Tripathi, Tripath's chairman, president and CEO. "The combination of high quality sound and high efficiency is the key to professional audio. Specifically, in the RAMSA amplifier, Tripath's amplifiers run so cool we eliminated the need for a cooling fan. We believe that Tripath's Class-T(TM) advanced 1-bit digital technology is able to meet the demands of compact, high power, high fidelity systems across a wide variety of audio entertainment product categories."

About Advanced Class-T(TM) 1-bit Sigma Delta Digital Audio Amplifiers

Tripath's advanced Class-T(TM) 1-bit digital audio amplifiers rely on a fundamentally new approach to amplifier design utilizing semiconductor-based amplifiers that provide significant performance, power efficiency, size and weight advantages over traditional amplifier technology. Instead of conventional pulse width modulation, Class-T(TM) employs multiple signal processing techniques, including adaptive/predicative processing, noise shaping, pre-distortion and sigma delta modulation.
