b)
Hold down the
DI REF
soft key and use the 6200’s front panel control knob to
adjust for an average of 10dB gain reduction on the 6200’s AGC meter.
Also, observe the
Gate
indicator. It should go out when program is present.
If the
AGC
gain reduction meter averages less than 10dB gain reduction
(higher on the meter), or if the
Gate
indicator stays on when program mate-
rial is present, re-adjust the
DI REF
level to a lower level.
If the
AGC
gain reduction meter averages more gain reduction (lower on the
meter), re-adjust the
DI REF
level to a higher level.
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).
4. Adjust R CH BAL (Right Channel Balance).
[Skip this step if the channels are already satisfactorily balanced.]
[
−
2dB to +2dB] on right channel only, 0.1dB steps
This is not a balance control like those found in consumer audio products.
This control changes gain of the right channel only. Use this control if the
right analog input to the 6200 is not at exactly the same level as the left in-
put. Be certain that the imbalance is not from a certain program source, but
only through distribution between the console output and 6200 input.
