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 in-
terface 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 micro-
phone input Pin 1 will be left fl oating,
which can lead to excessive back panel
microphone noise and cross talk. See
the table at right for pin defi nitions.
