S/PDIF (Sony/Philips Digital Interface) is a newest audio transfer file format, which provides impressive audio 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.
