Asus Xonar D2X is the world's first PCI-E interface high end audio card featuring SNR up to 118dB. Xonar D2 provides intuitive DS3D GX to solve Vista gaming audio issues, and Acoustic Echo Cancellation (AEC) for best voice communication quality, the Xonar D2X will undoubtedly provide the best gaming experience ever. With the introduction of Windows Vista, the whole audio architecture landscaped has been changed. This has resulted in teething problems for gamers - with the possibility of losing all surround sound or hardware accelerated Direct3D and EAX while gaming in the Windows Vista environment. To circumvent this problem, the ASUS Xonar family of audio cards utilizes an ASUS exclusive technology - the DS3D GX extension in the Xonar D2X driver; to provide full support for surround sound and hardware accelerated features by translating DirectX to the DS3D GX. While other solutions like OpenAL requires special installation and game support, DS3D GX doesn't. Gamers can enjoy DirectX gaming with hardware enhanced surround sound and EAX effects automatically and immediately after installation. The Xonar D2X also includes the innovative "Acoustics Echo Cancellation" (AEC) technology to facilitate the best online voice communication quality. AEC can eliminate up-to-40dB speaker echo return and suppress noises that would otherwise enter the users' microphone - making the Xonar D2X the best audio card choice for online chatting in VOIP applications (Skype, MSN, Google, QQ, etc.) or online gaming. Besides delivering impressive audio quality, the Xonar D2X is also packed with multiple sound technologies from Dolby and DTS to deliver outstanding entertainment experiences.
