You can apply this command anytime after the 8600 boots up. The 30-minute
timeout does not apply.

In HD Radio installations, this command is useful when switching the 8600 be-
tween transmitters if the transmitters’ exciters produce opposite FM modulation
polarities when driven by identical digital audio input signals. This setting affects
any output emitting the analog FM processed signal, including the composite
output.
5. To select the analog or digital input as the audio source:
Note: When the input is set to
D
IGITAL
and no valid digital signal is present at the
input, the setting of the
DI A
NALOG
F
ALLBACK
control will determine whether the
Optimod automatically switches to its analog input. See step 6 on page 2-29.
Command Response

(valid passcode and argument)
INPUT: [ANALOG, DIGITAL] (for each
output)
(invalid passcode)
[no error message is issued]
In the above table:
X = A, D
where A = analog input, D = digital input
PASSCODE = ANY VALID PASSCODE
.
•
If a non-existent control value and/or an invalid passcode is entered, the 8500
will ignore the command.

You can apply this command anytime after the 8500 boots up. The 30-minute
