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 SPDIF connector to a S/PDIF audio module bearing S/PDIF digital output. However,
you must have a S/PDIF supported speaker with SPDIF digital input to make the most of this function.
