S/PDIF
The system board is equipped with the S/PDIF (Sony/Philips Digital
Interface) digital audio interface. S/PDIF is a standard audio file
transfer format that transfers digital audio signals to a device without
having to be converted first to an analog format. This prevents the
quality of the audio signal from degrading whenever it is conver ted
to analog.
