Front Panel Audio Control Header
When front panel headphones are plugged in,
the back panel audio output is disabled. This
is done through the FP Audio header (AUDIO
FP). If the front panel interface card is not con-
nected to the front panel audio header, jumpers
should be installed on the header 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 oating, which can lead to excessive back
panel microphone noise and cross talk. See
the table below for pin denitions.
