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, is provided in the NB76-EA/EC system board
package. It is optional in the NB60-EL/EC system board package.
Install the card-edge bracket to the system chassis then connect the
appropriate audio cable connectors to J1 and J4. Make sure pin 1 of
the cable connectors is aligned with pin 1 of J1 and J4. 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.
