Last week at CeBIT, ASUS demonstrated its upcoming Xonar-series sound cards, available in two variants: the D2 and D2K in PCI and PCIe x1 interfaces. Dolby Digital Live and DTS Connect multi-channel audio encoding technologies are available for digital multi-channel audio while 7.1-channel analog outputs are available for those that prefer analog to digital. Unconfirmed reports claim the ASUS Xonar-series feature an Analog Devices audio DSP. ASUS also touts Dolby Pro Logic IIx, Dolby Virtual Speaker and Dolby Virtual Headphone technologies for multi-channel upconverting and surround sound. ASUS rates the Xonar-series with an 118dB playback and 115dB recording signal-to-noise ratios. The upcoming Xonar-series sound cards support 24-bit/192 KHz playback and recording resolutions as well as ASIO 2.0. ASUS internal testing reveals the Xonar-series is capable of low total harmonic distortion rates: 0.000006% THD on all eight analog outputs and the single line input, between the frequencies of 20Hz to 20 kHz. ASUS also equips the Xonar-series with an EMI shield and touts it provides "stable audio quality."
