noted in the following table. (Note that “advanced” controls are accessible only
from 6300 PC Remote software.)
These controls are explained in detail below.
Each Factory Preset has a
L
ESS
-M
ORE
control that adjusts loudness by altering the
amount of dynamics processing.
L
ESS
-M
ORE
simultaneously adjusts several of the
dynamics processing controls to optimize the trade-offs between unwanted side ef-
fects.
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 5-band structure is the sum of the gain
