D) Navigate to S

NALOG
C
ALIB
> AI R
EF
(VU or PPM, depending on which
metering system you use ) .
E) Calibrate using tone.
[Skip to step (F) if you are using Program material to calibrate the 6300 to
your standard studio level.]
a) Verify E
XT
AGC is set to N
O
.
Refer to step 2 on page 2-21.
b) Feed a tone at your reference level to the 6300
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
AI R
EF
(VU or PPM
)
control to make the 6300’s
AGC
meter
indicate 10 dB gain reduction.
d) Skip to step (G).
F) Calibrate using program.
[Skip this step if you are using Tone to calibrate the 6300 to your stan-
dard studio level—see step (E) above.]
a) Verify E
XT
AGC is set to NO .
Refer to step 2 on page 2-21.
b) Feed normal program material to the 6300
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).
c) Adjust the AI R
EF
(VU or PPM) control to make the 6300’s AGC meters
indicate an average of 10 dB gain reduction when the console’s VU meter
or PPM is peaking at its normal level.
If the
AGC
gain reduction meter averages less than 10 dB gain reduction
(higher on the meter), re-adjust the AI R
EF
(VU or PPM) to a lower level.
If the
AGC
gain reduction meter averages more gain reduction (lower on
the meter), re-adjust the AI R
EF
(VU or PPM) to a higher level.
G) When finished, reset E
XT
AGC to Y
ES
, if required (e.g., if that was its setting
prior to setting AI R
EF
(VU or PPM) level).
Refer to step 2 on page 2-21.
5. Adjust Right Channel Balance.
[Skip this step if the channels are already satisfactorily balanced.]
