S/PDIF (Sony/Philips Digital Interface) is a newest audio transfer file 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 with S/PDIF digital input to connect to the
S/PDIF digital output to make the most out of this function.
