INSTALLATION ORBAN Model 6200
Temporarily set the ST CHASSIS to “no” so that the Analog and Digital Input
reference level alignment steps (below) will work correctly. After you have
finished with these steps, you will set the ST CHASSIS parameter appropri-
ately for your installation.
4. Adjust MONO/ST selector.
[STEREO], [MONO-L], [MONO-R], or [MONO-S] for Mono-Sum
This determines which input channel drives the 6200 processing. Normal
operation is
STEREO
. However, you can also drive both channels with the left
input channel, the right input channel, or the mono sum of both input chan-
nels.
Analog I/O Setup
[Skip this step if you will not be using the 6200’s analog input or output, but
will only be using the AES/EBU digital input and output. Continue to step 1 on
page 2-30.]
For the following
I/O CALIB
parameters, use the soft keys to select in-
put/output parameters. While holding down the appropriate soft key, use the
front panel control knob to adjust the parameter settings, as desired.
If a parameter is not visible and the Next and Prev buttons are flashing, use
these buttons to scroll horizontally to access the desired parameter.
The screen as shown above lists all of the controls available for adjustment.
1. Adjust Input selector.
[Skip steps 1-4 if you will not be using the 6200’s analog input. Continue to

The 6200 will automatically revert to analog input if no valid input is avail-
able at the AES/EBU input.
2. Adjust AI CLIP control.
[+5.0dBu to +27dBu] in 0.5dB steps
This step matches the level at which the 6200’s A-D (Analog-to-Digital) con-
verter clips to the absolute maximum peak level that your installation supplies
to the 6200’s analog input.
