10. S/PDIF Connector
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.
