- Tech Report Editor's Choice (http://www.techreport.com/articles.x/14500)

• Powered by complete Dolby Home Theater technologies
• Supports latest DS3D GX 2.0 for gaming on Vista & XP
• VocalFX voice processing technologies to make gaming and online chat more lively and attractive
• Delivers up tp 35 times cleaner audio quality (116dB SNR) than most motherboard audio (85dB SNR)

• 35 Times Cleaner Audio Quality
Today's motherboards feature onboard audio solutions rated between 80-86 dB SNR. Low quality components and electrical interference introduce unintentional noise and distortion to the overall audio experience. Adopting CirrusLogics CS4398 Digital Analog Convertors (120 dB SNR & 117 dB THD+N), the Xonar DX achieves 30% cleaner sound. The Xonar DX dramatically minimizes the output of background noise, as little as 1/32 (-105dB) of the total harmonics distortion versus traditional motherboard audio (-75dB). Listeners can now enjoy clean audio as it was meant to be heard.

• Latest DirectSound & EAX 5.0 Compatibility
With Windows Vista's new audio architecture, many gamers are unable to take advantage of multi-channel sound, DirectSound; and EAX 5.0 sound effects in PC games. The Xonar DX solves all these problems. With DS3D GX 2.0 technology, the Xonar DX supports the latest EAX effects and DirectSound out of the box. Gamers can dive into a truly engaging sonic experience.

• Innovative VocalFX Enliven Online Chat
VocalFX applies voice processing technology to gaming landscapes (VoiceEX), and emulates background scenes in online chat (ChatEX). It also allows users to disguise or modify the pitch of their voice (MagicVoice). With VocalFX, online voices are a part of the game.

• Low Profile Design and Front Panel Header
The Xonar DX's low profile design and its bundled mini-bracket offers compatibility with small form factor and home theater PC chassis. A front-panel header makes headphones and microphones conveniently accessible from the front.

• Dolby Sound Technologies
Similar to other ASUS Xonar audio solutions, the Xonar DX card is packed with multiple Dolby sound technologies to deliver outstanding multimedia entertainment. Special features include Dolby Digital Live, which converts PC or game audio content into Dolby Digital in real-time; Dolby Headphone, which simulates a surround sound listening experience using any set of headphones; Dolby Virtual Speaker, which delivers a vibrant surround sound listening experience from stereo speakers and Dolby Pro Logic IIx, which creates up to 7.1-channel surround sounds from stereo or 5.1 sources.
