INSTALLATION ORBAN Model 6200
Digital I/O Setup
[Skip these steps if you will not be using the 6200’s digital input and output.
Refer to page 2-24 to set the 6200’s analog I/O.]
For the following I/O Calibration 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.
1. Adjust Input selector.
[Skip steps 1-4 if you will not be using the 6200’s digital input. Continue to
step 6 on page 2-32.]
A) Press
Setup
button to access Setup screen.
B) Press
I/O CALIB
soft key, then press
DIG IN CALIB
soft key to access Analog In-
put/Output calibration controls.
C) Set the
INPUT
control to
digital
.
The 6200 will automatically revert to analog input if no valid input is avail-
able at the AES/EBU input.
2. Set DI MODE.
[normal], [J.17].
If your STL is pre-emphasized with J.17 pre-emphasis, set
DI MODE
to J.17.
This will apply J.17 de-emphasis to the digital input.
Ordinarily only NICAM links will be pre-emphasized to
J.17
.
Otherwise set
DI MODE
to
normal.
3. Adjust Digital Input Calibration.
A) Adjust
DI REF
(Digital Input Reference) level.
[−30 to –10dBfs (VU), or –22 to –2dBfs (PPM)] in 0.5dB steps.
The
DI REF VU
and
DI REF PPM
settings track each other with an offset of
8dB. This compensates for the typical indications with program material of a
VU meter versus the higher indications on a PPM.
This step sets the center of the 6200’s gain reduction range to the level to
which your studio operators peak their program material on the studio me-
ters. This assures that the 6200’s processing presets will operate in their pre-
ferred range.
You may adjust this level with a standard reference/line-up level tone from
your studio or with program material.
