ASUS Xonar DX 7.1 Channels PCI Express x1 Interface Sound Card. 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.
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 music.
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.
The Xonar DX is bundled with a low profile bracket for compatibility with HTPC cases.
VocalFX is an innovative voice processing technology to let your voice get into the realistic game landscape (VoiceEX) or to emulate the background scenes in online chat (ChatEX). It also allows you to change your voice pitch to disguise who you are (Magic Voice).
