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.
