SPDIFO1: S/PIF Out Header

S/PDIF (Sony/Plilips Digital Interface) is a standard audio transfer file format and

allows the transfer of digatal audio signals from one device to another without

having to be converted first to an analog format. Via a specific audio cable, you can

connect the SPDIFO1 header (S/PDIF output) on the motherboard to the S/PDIF

digital input on the external speakers or AC Decode devices.
