The 4-channel audio connector (J14) supports 4 audio output
signals: center channel, subwoofer, rear right channel and rear left
channel. The line-in and mic-in jacks (at the rear panel) together with
the 4-channel audio connector supports 6-channel audio output. One
card-edge bracket, mounted with a 4-channel audio output
connector, will be provided as an option. Install the card-edge
bracket to the system chassis then connect the audio cable
connector to J14. Make sure pin 1 of the cable connector is aligned
with pin 1 of J14. Now connect the external speakers’ cable
connector to the 4-channel audio output connector that is on the
bracket.
Note:
If, for any reason, you are not using the 4-channel audio
connector which is made possible by connecting a 4-channel
audio cable, the 6-channel audio output function can be
supported using software. Refer to chapter 4 for more
information.
