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.
