B)
Set the
I
NPUT
to Analog.
The 9400 will automatically switch to its analog input if signal lock is un-
available at its AES3 input.
4.
Adjust Analog Input Reference Level.
[
9dBu to +13dBu (VU), or –2 to +20dBu (PPM)] in 0.5 dB steps
[Skip this step if you will not be using the analog input.]
The reference level VU and PPM (Peak) 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 9400’s gain reduction range to the level to which
your studio operators peak their program material on the studio meters. This as-
sures that the 9400’s processing presets will operate in their preferred range.
You may adjust this level with a standard reference / line-up level tone from your
studio or with program material.
Note that in this step, you are calibrating to the normal indication of the studio
meters; this is quite different from the actual peak level.
If you know the reference VU or PPM level that will be presented to the 9400, set
the reference level to this level, but please verify it with the steps shown directly
below.
A)
Press the

your standard studio level.]

Refer to step 1 on page 2-23.
b)
Feed a tone at your reference level to the 9400
If you are not using a studio level controller, feed a tone through your
console at normal program levels (typically 0VU if your console uses VU
meters).
If you are using a studio level controller that performs an AGC function,
such as an Orban 8200ST OPTIMOD-Studio, adjust it for normal opera-
tion.
c)
Adjust the
