8. S/PDIF (Sony/Philips Digital Interface) Connector
S/PDIF (Sony/Philips Digital Interface) is a latest audio transfer file format that provides
impressive quality through optical fiber and allows you to enjoy digital audio instead of
analog. Normally there are two S/PDIF outputs as shown, one for RCA connector, the most
common one used for consumer audio products, and the other for optical connector with a
even better audio quality. Through a specific audio cable, you can connect the S/PDIF
connector to a S/PDIF audio module bearing S/PDIF digital output. However, you must have
a S/PDIF supported speaker with S/PDIF digital input to make the most of this function.
