ASUS Xonar DX Audio Card

The ASUS Xonar DX Audio card is impeccably designed for fine-tuned audio quality with 116dB SNR (Signal-to-Noise Ratio) in comparison to most Motherboard onboard audio with only 85dB SNR. It is equipped with innovative technologies like Dolby Home Theater Technologies and DS3D GX to provide crisp and clear audio quality and rich gaming Sound effects. The Xonar DX dramatically reduces the amount of background noise, producing as little as 1/32 (-105dB) of the total harmonics Distortion versus traditional motherboard audio (-75dB). 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. 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.
