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 converted

to analog.
