D2AUDIO'S 'XRT' IS THE FIRST DIGITAL AMPLIFIER TO MEET THX ULTRA2 AMPLIFIER PERFORMANCE CRITERIA

This compact yet extremely powerful amplifier module meets the performance levels of today's best audio amplifiers.

AUSTIN (Texas) - November 10, 2004 - - -D2Audio, the technology leader in intelligent digital amplification, today announced that its 7 channel 125w/channel XRT125 -7 amplifier module is the world's first digital amplifier capable of meeting the stringent THX Ultra2 certification amplifier performance levels for Audio/Video Receivers. This compact yet extremely powerful amplifier module meets the performance levels of today's best audio amplifiers. This achievement was accomplished in combination with the new D2Audio CXT350 "Audio -Grade" switch mode power supply. This distinction underscores the outstanding audio performance and superior sound achieved by D2Audio's digital amplifiers and technology.


Across the globe, many top brands in consumer electronics demonstrate that their products will deliver end users a superior listening experience by achieving THX certification. Until now, all of these products have been relegated to using traditional linear amplifiers as no digital amplifiers could deliver the performance required to meet THX certification levels. Consumer electronic companies can leverage D2Audio's XRT125 -7 amplifier module to develop compelling Audio/Video Receivers enabled to achieve the highest levels of audio performance and quality, and with much lighter and lower profile end products. With D2Audio, they can also enjoy the many unique features and benefits delivered by D2Audio's all -digital intelligent technology.

"Appropriately, D2Audio is the first digital amplifier to achieve the high performance of THX Ultra2 amplifier specifications," said John Stiernberg principal consultant with Stiernberg Consulting, the Los Angeles -based business development firm. "D2Audio's amplifiers deliver market leading performance levels that will help accelerate the market transition from analog audio to the benefits of digital. Achieving THX amplifier performance levels is another star in their crown."

"While thousands of commercial cinemas, post -production studios, and home entertainment products have been certified by THX, D2Audio is the first digital audio amplifier to achieve the amplification performance levels required to be capable of THX certification," said Michael Franzi, vice president of sales at THX.

THX Ultra2 requires superior performance and the ability to:

· Deliver extreme levels of peak power under the toughest of conditions

· Maintain ultra -low levels of distortion (THD + N) at all power levels

· Maintain an exceptionally flat frequency response, regardless of the speaker impedance load

· Deliver a very superior Signal to Noise Ratio (SNR)

The D2Audio Corporation, maker of the world's only custom intelligent digital amps, supplies a full line of powerful, multi -channel amplifier modules to the manufacturers of high quality audio equipment in the consumer, commercial, professional and automotive industries. Their patented intelligence technology and custom controller IC gives D2Audio's digital amps market leading performance and superior sound quality, along with a wide range of customization features.
