Front Audio Connector: F_AUDIO1
(for -6 models)
The audio port includes two parts
–
the Front
Audio and Rear Audio. Their priority is se-
quenced 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.
