This is not a balance control like those found in consumer audio prod-
ucts. This control changes the gain of the right channel only. Use this
control if the right analog input to the 8500S is not at exactly the same
level as the left input. Be certain that the imbalance is not caused by one
program source, but is instead introduced through distribution between
the console output and 8500S input. This adjustment is best accomplished
by playing program material that is known to be monophonic or by set-
ting 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.]
A) Navigate to Setup > I/O C
B) Repeat steps 1 through 4 (starting on page 2-26), but use the DI R
PPM) and R CH BAL controls for the digital section.
6. Set response to an invalid or missing analog or digital input signal. (op-
tional)
Refer to step 3 on page 2-24
7. Defeat final clipper (optional).
If you are using the 8500S to drive a network with protection audio processors
(like Orban's Optimod-FM 8500S) at each transmitter, you may wish to defeat the
8500S's final clipper to prevent double clipping, which will unnecessarily increase
distortion on-air. To do this:
A) Navigate to the Setup > F
press the Next button until it does.
In PC Remote, this control is located in I/O > U
B) Set F

This will also defeat the overshoot compensator.
Note that defeating the final clipper and overshoot compensator will in-
crease peak output levels, possibly to the point where the 8500S's output
amplifier and/or digital output clips. It is wise to customize any presets
you are using by reducing the F
controls to their minimum values. This will greatly reduce the probability
of inadvertently clipping the 8500S's output.
Unless defeated, the 8500S's composite limiter will continue to control
the composite output level. However, you should not use the composite
output when the 8500S's final clipper is defeated because this will re-
control to achieve correct left/right channel balance.
