FP Audio
When front panel headphones are plugged in, the back panel audio output is disabled.
This is done through the FP Audio header (J12). If the front panel interface card is
not connected to the front panel audio header, jumpers should be installed on the
header (J12) 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.

(headphone drive capable)
6 FP_RETURN_R
Right channel audio signal return from front
panel (when headphones unplugged)
