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

The crossover frequencies in three-band mode are 200Hz and 2.45kHz.
Click the Bands button to change the mode. Alternately, you can click+hold
the LED area and drag like a slider to change the value.
Note: UAD DSP usage is increased when three-band mode is active.
Limit
The Limit function provides a second stage of soft-saturation just before
the output control for the plug-in. It prevents digital “overs” by
protecting the plug-in output from exceeding 0dBFS. Limit enters into
clipping range gradually instead of hard-clipping at 0dB.
The Limit function has the same saturation form as the Shape parameter, but
the effect is milder. Limit is especially useful for three-band mode, where output
peaks over 0dB (and clipping) can occur. However, great results can also
be obtained in one-band mode when Limit is engaged.
If Limit is used to reduce levels by a significant amount, it is usually best to
have Mix set to 100% in order to minimize audio artifacts (aliasing).
Click the Limit button to engage Limit. Alternately, you can click+hold the LED
area and drag like a slider to change the value.
Note: UAD DSP usage is slightly decreased when Limit mode is inactive.
Mix
The Mix knob is a mix control for the plug-in. Mix determines
the balance between the original and the processed
signal.
The range is from 0% (no processing) to 100% (wet, processed
signal only).
Note that when Mix is at 0%, the signal is still processed
by the Limit control if it is enabled, and by the band splitter
when in three-band mode. For a true bypass, the Power
switch should be used.
