You can turn the AGC off globally for all presets, which is convenient if
you don't expect to use it in the future. See step (3.C) on page 2-23.

If you are using the Five-Band structure, you can use the D
controls to fine-tune the release time of each band independently.
The release characteristic is always "automatic" (i.e., with program-
dependent time constants) and the R
cess. This, combined with multiband operation, makes the compression
remarkably resistant to the usual compressor pumping and squashing.

The K
control automatically and invisibly changes a given band's in-

ternal compression threshold to keep the compressor's output level con-
stant whenever the drive level is high enough to move the gain reduction
into the ∞:1 range. This means that the internal threshold decreases with
softer knee settings (higher settings of the K
