The Xonar DX is capable of delivering 35 times cleaner audio quality with 116dB SNR in comparison to most motherboard onboard audio with only 85dB SNR. While noise is unavoidable, the Xonar DX dramatically reduces the amount of background noise, and it is this distinction that allows the Xonar DX to produce as little as 1/32 (-105dB) of the total harmonics distortion versus traditional motherboard audio (-75dB). As most onboard audio only provide 80~86 dB SNR audio quality, background noises are easily heard while listening to music or playing games. By adopting the CirrusLogics CS4398 audio DAC (120dB SNR & 117dB THD+N) that is often used in Hi-Fi devices, the Xonar DX provides at least 30% better quality sounds than the average onboard audio.

With the new audio architecture in Vista, users will sometimes be unable to achieve multi-channel sounds, DirectSound; and EAX 5.0 sound effects in EAX 5.0 Titled PC games. With the ASUS Xonar DX, all these problems will be solved. With support for the innovative DS3D GX 2.0 technology, the Xonar DX automatically supports the latest EAX and DirectSound HW after installation without the need to search for additional drivers or OpenAL – as most games are DS3D/DirectX compatible.

VocalFX is an innovative voice processing technology for users’ voices to enter into the realistic gaming landscape (VoiceEX), or to emulate the background scenes in online chats (ChatEX). It also allows them to disguise their voice pitches (Magic Voice). With all these features, users will have boundless entertainment while utilizing voice communications on the PC.

Besides delivering impressive audio quality, the Xonar DX, like other members of the Xonar family of audio devices, is also packed with multiple sound technologies from Dolby to deliver outstanding entertainment experiences. These include Dolby Digital Live, which converts PC or game audio content into Dolby Digital in real-time; Dolby Headphone, which creates a surround sound listening experience when 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.
