Front Panel Audio Control
When front panel headphones are plugged
in, the back panel audio output is disabled.
This is done through the FP Audio header
(JC2). If the front panel interface card is
not connected to the front panel audio
header, jumpers should be installed on
the header (JC2) pin pairs: 1-2, 5-6, and
9-10. If these jumpers are not installed,
the back panel line out connector will
be disabled and microphone input Pin
1 will be left fl oating, which can lead to
excessive back panel microphone noise
and cross talk. See the table below for
pin defi nitions.
