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 connected 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 floating,
which can lead to excessive back panel
microphone noise and cross talk..
