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 to protect a transmission link before OPTIMOD-PC.
However, in this case it is better to defeat the AGC globally in System Setup [see step
(3.C) on page 2-23].
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 five-band compressor. The total
system gain reduction determines how much the loudness of quiet passages will be
increased (and, therefore, how consistent overall loudness will be). It is determined
by the setting of the AGC D
or PPM is peaked, and by the setting of the M
