UAD Powered Plug-Ins Manual v5.2 - Just Music

Toggling the Fade switch causes an already active fade to reverse direction,
without a jump in output level. The Fade Set rate is constant even if an active
fade is interrupted. For example: If the Fade Set value is 30 seconds and a
fade out is initiated, then Fade is clicked again after 20 seconds, it will take
20 seconds to fade back in.
Note: Shift+click the Fade button to instantly return the level back to 0dB (this
feature cannot be automated).
Input Level
Input controls the signal level that is input to the plug-in. Increasing
the input may result in more compression, depending on
the values of the Threshold and Ratio parameters.
The default value is 0dB. The available range is ±20dB.
Mix
The Mix control determines the balance between the original
and the processed signal. The range is from 0% (dry unprocessed
signal only) to 100% (wet processed signal only). The
default value is 100%.
Output Level
Output controls the signal level that is output from the plug-in.
The default value is 0dB. The available range is ±20dB.
Output controls both the dry unprocessed and wet processed
signals (as determined by the Mix control).
Generally speaking, adjust the Output control after the desired amount of
compression is achieved with the Threshold and Ratio controls. Output does
not affect the amount of compression.
Level Meters
The stereo peak/hold Input
and Output Meters display the
signal level at the input and
output of the plug-in.
The range is from -30dB to 0dB. Signal peaks are held for 3 seconds before
resetting.
