Front Panel Audio
When front panel headphones are
plugged in, the back panel audio output
is disabled. This is done through the FP
Audio header (JC1). If the front panel in-
terface card is not connected to the Front
Panel Audio header, jumpers should be
put on the pin-pairs of 1/2, 5/6, and 9/10
on the FP Audio Header. 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 on the right for pin defi nitions.
