Asus Xonar D2 Manual

Asus Xonar D2 User Manual

Beyond cosmetics, the Xonar D2 is a 7.1-channel affair, based on the ASUS AV200 audio processor, which was 'developed in cooperation with C-Media', and boasts a stratospheric 118dB signal-to-noise ratio. If that wasn't enough, ASUS states that the 118dB spec is valid for all seven output channels, in addition to the LFE channel. ASUS further tells us that this is different from some other generic audio card manufacturers, who only give the SNR for the two front channels, and use cheaper signal components for the other channels.
