Front Audio Connector : F_AUDIO
The audio interface provides two kinds of audio
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.
SP
The SPDIF out connector is capable of providing digital
audio to external speakers or compressed AC3 data to
an external Dolby digital decoder.
Note: The empty pin of SPDIF cable should be aligned
to empty pin of the S/PDIF_OUT connector.
The connectors connect to the chassis security switch on the case. The system
can detect the chassis intrusion through the status of this connector. If the
connector has been closed once, the system will send a message. To utilize
this function, you should enable the relevant item in the "Power Management
Setup" section of the CMOS Setup. Save and exit, then boot the operating sys-
tem once to make sure this function takes effect.
USB Headers: F_USB1, F_USB2
Besides four USB ports on the rear panel, the series of motherboards also have
two 10-pin headers on board which may connect to front panel USB cable
(optional) to provide additional four USB ports.
