The ASUS Xonar DX is a PCI-E sound card with a 116 dB Signal-to-Noise Ratio (SNR), which provides audio that is 35 times cleaner than onboard audio. With the support of Dolby technologies and GX2.5, the Xonar DX provides rich audio effects in games and theater quality audio in movies.

Dolby is globally recognized for their innovations in audio for cinemas, home theaters, PCs, and games. With Dolby technologies, your PC is upgraded to surround sound and transformed into an immersive digital entertainment center. These include Dolby Digital Live (Real-time 5.1 Dolby Digital surround sound encoding), Dolby Pro-Logic IIx (Converts stereo or 5.1 sounds to a seamless 7.1 surround sound field), Dolby Headphone (Delivers a realistic and spacious 2-to-5.1 surround or 3D positional sound field over any set of stereo headphones), and Dolby Virtual Speaker which simulates a highly realistic 5.1 speaker surround sound listening environment from as few as 2 speakers.

ASUS designed GX2.5 to simulate EAX game effects and makes them available on Windows Vista/7 PCs. GX2.5 will automatically emulate the latest EAX technologies without additional software.
