S/PDIF (Sony/Philips Digital Interface) is a newest audio transfer format, which provides impressive
quality through optical fiber
and allows you to enjoy digital audio instead of analog audio. 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 better audio quality.
Through a specific audio cable, you can connect the S/PDIF connector to other end of the S/PDIF audio module, which bears
S/PDIF digital output. However, you must have a S/PDIF supported speaker/amplifier/decoder with S/PDIF digital input to
connect to the S/PDIF digital output to make the most out of this function.
