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/7/8 PCs. GX2.5 will automatically emulate
the latest EAX technologies without additional software.
High Signal-to-Noise Ratio (SNR)
A high SNR rating means less unwanted noise. Therefore the audio is
cleaner which translates to better sound quality. The Xonar DX
achieves a 116 dB SNR rating for clear audio in games, movies, and
A rich Dolby feature set is supported in order to enhance PC audio
with surround sound. A surround sound experience can be achieved with
as little as two speakers or even headphones.
GX2.5 automatically emulates the latest EAX technology – up to
EAX5.0, to offer advanced environmental audio effects. While enhancing
the feeling of actually being in the game, GX2.5 also improves on
directional audio information.
Low Profile The Xonar DX is bundled with a low profile bracket for compatibility with HTPC cases.
