INSTALLATION
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
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 5500 to your stan-
dard studio level — see step (D) above.]
a) Verify E AGC is set to NO.
XT
Refer to step 1 on page 2-28.
b) Feed normal program material to the 5500
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
indicate an average of 10 dB gain reduction when the console's VU meter
or PPM is peaking at its normal level.

4. Adjust Right Channel Balance.
[Skip this step if the channels are already satisfactorily balanced.]
[3 dB to +3 dB] on right channel only, 0.1 dB steps

This is not a balance control like those found in consumer audio prod-
ucts. This control changes gain of the right channel only. Use this control
if the right analog input to the 5500 is not at exactly the same level as
the left input. Be certain that the imbalance is not caused by one pro-
gram source, but is instead introduced through distribution between the
console output and 5500 input. This adjustment is best accomplished by
playing program material that is known to be monophonic or by setting
the mixing console into mono mode (if available).
5. Adjust the Digital Input Reference Level and Right Balance controls.
[Skip this step if you will not be using the digital input.]
