SAN JOSE, Calif.--(BUSINESS WIRE)--April 17, 2003

Tripath Technology Inc. (Nasdaq:TRPH), creators of Class-T advanced 1-bit Digital Audio Amplifiers, announced today that its advanced 1-bit digital amplifier, TA2022, has been selected to power Denon's latest sub-woofer, DSW-7L. This sub-woofer is the second Denon product powered by Tripath's Class-T patented technology after their home theater system, DHT-1000DV-S.

Denon's DSW-7L, a stylish sub-woofer with three-color variations, utilizes the highly efficient and high fidelity TA2022 amplifier to provide up to 200 watts of power. Tripath's patented signal processing techniques are combined with a switch mode approach that generates high fidelity sound with significantly lower heat dissipation making it ideal for compact design applications such as a sophisticated sub-woofer.

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

"We are very pleased that Denon, a world leader in the high quality audio market, has released the second product with Tripath Technology's proprietary and leading-edge technology," said Graham Wright, vice president of Sales and Marketing for Tripath.
