Adjust the R C
achieve correct left/right channel balance.
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 6300 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 instead is introduced through distribution between the
console output and 6300 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).
6. Adjust the Digital Input Reference Level and Right Balance controls.

This control is only relevant if you are using the AGC+LIM feed at one or
more 6300 outputs. The control determines whether the look-ahead lim-
iter after the AGC operates on a flat or preemphasized signal.
50S and 75S preemphasis are only useful if the 6300 is protecting a
transmission link that uses preemphasis (like certain satellite uplinks). Use

When operated pre-emphasized, the 6300's AGC look-ahead limiter
should only provide light protection limiting. If you use too much gain
reduction in the look-ahead limiter, you will hear pumping on material
with a lot of high frequency energy.
8. Set Multiband preemphasis.
A) Navigate to S
B) Select the desired multiband preemphasis (50S or 75S) by turning the knob.
This control is only relevant if you are using the MB+LIM feed at one or
more 6300 outputs. The control determines whether the look-ahead lim-
iter after the 2-band or 5-band compressor operates on a flat or preem-
phasized signal.
