INSTALLATION ORBAN MODEL
•
Analog Input Silent : Indicates that the level at either or both analog in-
put channels is below the threshold set in step 3 on page 2-24.
•
AES Input Silent : Indicates that the level at either or both digital input
channels is below the threshold set in step 3 on page 2-24.
•
AES Input Error : Indicates that the 8600Si’s AES input receiver chip has de-
tected a problem with the data being received such that the data is unus-
able. When the chip detects such an error, it automatically switches the in-
put to
A
NALOG
.
•
Sync Reference Input Error : Indicates that the 8600Si has detected a
problem with the signal being received at the sync reference input such
that the signal is unusable.
•
When pilot sync is specified (
S
ETUP
> I/O C
ALIB
> D
IG
O
UT
C
ALIB
> DO S
YNC
) and
such an error is detected, the 8600Si automatically switches the sync source to
the digital input.
•
If there is no valid digital input signal at the digital input, the sync source de-
faults to the 8600Si’s internal clock.
•
No Function : Tally output is disabled.
C) Program tally output #2 if you wish, following the procedure in step (B) above

The following material provides detailed instructions on how to set up the 8600Si. If
QUICK SETUP does not fully address your setup needs or if you wish to customize
your system beyond those provided with QUICK SETUP, then you may need the addi-
tional information in the sections below. However, for most users, this material is
only for reference because QUICK SETUP has enabled them to set up the 8600Si cor-
rectly.
Analog and Digital I/O Setup
For the following adjustments, use the appropriately labeled soft button to choose
the parameter to be adjusted. To change a parameter (like an output level), it is usu-
ally necessary to hold down the soft button while turning the knob.
1. Temporarily set the external AGC mode to “No.”
A) Navigate to Setup

> E
XT
AGC
and set
E
XT
AGC
to
N
O . (It may be
set to
N
O already.)
If you are using a external AGC like the Orban 6300, you should restore
this setting to
Y
ES after the setup procedure is complete.
