OPERATION ORBAN MODEL 8382
Five of the AGC controls are common to the Full Modify and Advanced Modify
screens, with additional AGC controls available in the Advance Modify screen, as
noted in the following table. (Note that “advanced” controls are accessible only
from 8382 PC Remote software.)
These controls are explained in detail below.
Each Factory Preset has a L
ESS
-M
ORE
control that adjusts on-air loudness by altering
the amount of processing. L
ESS
-M
ORE
simultaneously adjusts all of the processing
controls to optimize the trade-offs between unwanted side effects.
If you wish, you may adjust the Advanced Modify parameters to your own taste. Al-
ways start with
L
ESS
-M
ORE
to get as close to your desired sound as possible. Then
edit the Advanced Modify parameters using the Advanced Modify screen, and save
those edits to a User Preset.
AGC (“AGC Off / On”)control activates or defeats the AGC.
It is usually used to defeat the AGC when you want to create a preset with minimal
processing (such as a
CLASSICAL preset). The AGC is also ordinarily defeated if you
are using a studio level controller (like Orban’s 8200ST). However, in this case it is
better to defeat the AGC globally in System Setup.
AGC DRIVE control adjusts signal level going into the slow dual-band AGC, there-
fore determining the amount of gain reduction in the AGC. This control also adjusts
the “idle gain”—the amount of gain reduction in the AGC section when the struc-
ture is gated. (It gates whenever the input level to the structure is below the thresh-
old of gating.)
The total amount of gain reduction in the Five-Band structure is the sum of the gain
reduction in the AGC and the gain reduction in the multiband compressor. The total
