S/PDIF_Out Connector: SPDIF_OUT
The S/PDIF out connector is capable of provid-
ing digital audio to external speakers or com-
pressed AC3 data to an external Dolby digital
decoder.
Front Audio Connector : F_AUDIO
The audio interface provides two kinds of au-
dio output choices: the Front Audio, the Rear
Audio. Their priority is sequenced from high to
low (Front Audio to Rear Audio). If headphones
are plugged into the front panel of the chassis
(using the Front Audio), then the Line-out (Rear
Audio) on the rear panel will not work. If you do
not want to use the Front Audio, pin 5 and 6, pin
9 and 10 must be SHORT, and then the signal
will be sent to the rear audio port.
