Diagram 3:

DE-COMPRESSION mode

COMPRESS control is set to
three values: 2, 4, and 7

GAIN set to  0 dB

Diagram 4:

DE-COMPRESSION plus SOFT
LIMIT mode

COMPRESS control is set to
three values: 2, 4, and 7

GAIN set to  0 dB

Also the intonation of a Kick Drum is improved resulting in a

better grooving rhythm. Remember that the operation of the
GAIN control (4) is inverted when the DE-COMPRESSION mode is
active.Turning the GAIN control clockwise lowers the output level
to compensate for the level increase.

The DE-COMPRESSION mode has only a limited usability when

processing stereo sources, but it can be useful to create special
effects where the loudest sound elements practically jump out of
the mix! After reducing the GAIN to restore the original peak level,
you will naturally lose loudness.

The following measurements show various DE-COMPRESSION

characteristics:

You can easily see from diagram 4, how the processing intensity

is increased when the SOFT LIMIT mode is used at the same time
as the DE-COMPRESSION mode. Peak levels will be amplified even
more in this case.
