25.3.3 Dynamics
A click on D opens the
Dynamics panel with Compressor, Expander and Auto Level. They are
available in all input and output channels, and affects all routings of the respective channel.
Dynamics. Activated by this button.
Thresh. Threshold where Compressor or Expander start to
work. The Compressor is adjustable from -60 dB to 0 dB,
the Expander is adjustable from -99 dB to -20 dB.
Ratio. Ratio of input to output signal. Defines the intensity
of the signal processing. Adjustable from 1 to 10.
Gain. Gain stage to compensate a loss in level caused by
the Compressor. Adjustable from -30 to +30 dB. With inac-
tive Compressor (Threshold 0 dB, Ratio 1:1) this function
can also be used as universal digital gain stage.
Attack. Defines the rise time for the control voltage of
Compressor/Expander. Adjustable from 0 ms to 200 ms.
Release. Defines the release time for the control voltage of
Compressor and Expander. Adjustable from 100 ms to 999 ms.
The amplitude graphics give a precise overview of the level changes caused by the current set-
tings of Compressor and Expander. The white dot shows the level of the input signal and with
this whether the signal is within the processing range or not. The small light blue lines in the level
meter show the currently active gain reduction. Settings for these
Dynamic Meters are found in
the Preferences dialog (F2).
Auto Level. Activated by this button.
Max. Gain. Defines the maximum amplification of the input signal. Adjustable from 0 dB to 18
dB.
Headroom. To minimize short-time overloads
and clipping of the signal peaks Auto Level can
be set to operate at a fixed offset to 0 dBFS.
Adjustable from 3 dB to 12 dB.
Rise Time. Defines the speed of a level increase
after a level reduction. Adjustable from 0.1 s to
9.9 s.
Preset. Includes the same functions as de-
scribed on the previous page for the Equalizer.
The names of the Factory Presets make clear
whether Compressor, Auto Level or both (C+A)
have to be switched on.
