The 4-channel audio connector (J8) supports 4 audio output signals:
center channel, subwoofer, rear right channel and rear left channel. The
4-channel audio connector together with the line-in and mic-in jacks
(at the rear panel) 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 J8. Make sure pin
1 of the cable connector is aligned with pin 1 of J8. 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.
