Front Audio
The front audio connector (J1) allows you to connect to the
line-out and mic-in jacks that are at the front panel of your sys-
tem. Using this connector will disable the rear audio's line-out
and mic-in functions.
Remove the jumper caps from pins 5-6 and pins 9-10 of J1 prior
to connecting the front audio cable connector. Make sure pin 1
of the cable connector is aligned with pin 1 of J1. If you are not
using this connector, make sure to replace the jumper caps back
to their original pin locations.
Pins 5-6 and 9-10 short
(default)
Pins 5-6 and 9-10 open
