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.
Note that in this step, we are calibrating to the normal indication of the stu-
dio meters; this is quite different from the actual peak level or actual average
or RMS level.
If you know the reference VU or PPM level that will be presented to the
6200, set the

[Skip this step if you are using Program material to calibrate the 6200 to
your standard studio level. Skip to step (F).]
If you are not using a studio level controller, feed a tone through your con-
sole at the level to which you normally peak program material (typically
0VU if your console uses VU meters).
If you are using an Orban 4000 Transmission Limiter, press its two
buttons. Feed a tone through your console at the level to which you normally
peak program material (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 or 464A, adjust it for normal
operation.
