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
DI REF
level to this level, but do verify it with the steps shown
directly below.
B)
Press the
Recall
button.
C)
Turn the knob until you see
next: GENERAL–MEDIUM
.
D) Press the RECALL NEXT soft key.
E) Calibrate using Tone — feed a tone at your reference level to the 6200.
[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
TEST
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.
a) Verify ST CHASSIS is set to no .
Refer to step 3 on page 2-23 above.
b)
Hold down the
DI REF
soft key and use the 6200’s front panel control knob to
adjust for 10.0dB on the 6200’s AGC meter.
This control has no effect on the AES/EBU digital input.
c) When finished, reset ST CHASSIS to yes , if required (e.g., if that was its setting
prior to setting the
DI REF
level).
d)
Skip to step 4.
F) Calibrate using Program — feed normal Program material to the 6200.
[Skip this step if you are using Tone to calibrate the 6200 to your standard
studio level — see step (E) above.]
Play program material from your studio, peaking at the level to which you
normally peak program material (typically 0VU if your console uses VU
meters).
a)
Verify
ST CHASSIS
is set to
no
.
Refer to step 3 on page 2-23 above.
