What are the most important benefits of the Xonar Essence ST for

musicians?

in/out for the cleanest sound production.

Duplex HD: Supports audio sampling rates up to 24bit/192KHz for all

inputs and outputs.

ASIO 2.0: Xonar Essence ST includes an ASIO 2.0 driver for low-latency,

low-distortion music creation application.

Will PCM sound output through S/PDIF be limited to 2 channels even with

different analog output channels?
The S/PDIF protocol specification (IEC-60958) only carries the 2-channel PCM

data or non-PCM AC3/DTS data. Hence, when a user selects PCM output for

S/PDIF, the Xonar sound card always deliver a 2-channel PCM data through the

S/PDIF output port. For attaining 5.1 channel surround sounds, you can select

Dolby Digital Live encoding output from the S/PDIF out menu, which allows the

Xonar Essence ST to deliver 5.1 surround sound for DVD movies, and even stereo

music.
