2.8.8 S/PDIF-out Connector
The system board is equipped with a digital audio interface -
S/PDIF-out. S/PDIF (Sony/Philips Digital Interface) is a standard audio
file transfer format that transfers digital audio signals to a device
without having to be converted first to an analog format. This
prevents the quality of the audio signal from degrading whenever it
is converted to analog.
Connect the appropriate end of the audio cable connector to J38.
Make sure pin 1 of the cable connector is aligned with pin 1 of J38.
Now connect external speakers or a device that supports digital
output to the S/PDIF-out connector that is on the other end of the
audio cable.
