The system board is equipped with a digital audio interface - S/PDIF
(Sony/Philips Digital Interface). S/PDIF is a standard audio file transfer
format that transfers digital audio signals to a device without having
to be conver ted first to an analog format. This prevents the quality
of the audio signal from degrading whenever it is conver ted to
analog.
One card-edge bracket, mounted with 1 S/PDIF-in connector and 1
S/PDIF-out connector, will be provided as an option. Install the card-
edge bracket to the system chassis then connect the appropriate
audio cable connectors to J26 and J27. Make sure pin 1 of the
cable connectors is aligned with pin 1 of J26 and J27. Now connect
external speakers or a device that suppor ts digital output to the
S/PDIF-in and S/PDIF-out connectors for digital audio output.
