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 (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 oating, which can

lead to excessive back panel microphone

noise and cross talk. See the table below

for pin denitions.

JLED. This connection is used to pro-

vide LED Indication of power supplied to

the system. See the table on the right

for pin denitions.
