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 (Audio FP). If the front

panel interface card is not connected to

the front panel audio header, jumpers

should be installed on pin pairs 1-2,

5-6, and 9-10 of the Audio FP header.

If these jumpers are not installed, the

back panel line out connector will be

disabled, and pin 1 of the microphone

in will be left ﬂ oating, which can lead

to excessive back panel microphone

noise and crosstalk. See the table at

right for pin deﬁ nitions.
