Precision Buss Compressor Controls
Control knobs for the Precision Buss Compressor behave the same way as
with all UAD plug-ins. Parameters with text values can be modified with text
entry. See “Text Entry” on page 92 for more information.
Filter Filter regulates the cutoff frequency of the filter on the compres-
sor's control signal sidechain. Removing low-frequency content
from the sidechain can reduce excessive gain reduction
and/or “pumping” on bass-heavy audio signals without reduc-
ing bass content of the audio signal itself.
The filter is an 18 dB per octave, coincident-pole high-pass filter. The avail-
able range is 20 Hz–500 Hz and Off.
Note: The Filter parameter affects the control signal (sidechain) of the com-
pressor only. It does not filter the audio signal.
Threshold This parameter determines the threshold level for the onset of
compression. Incoming signals that exceed this level are com-
pressed. Signals below the level are unaffected.
The available threshold range depends on ratio setting. At
higher Ratio values, more headroom is available. Since the
plug-in is designed primarily as a buss compressor, where signal levels typi-
cally run hotter than individual tracks, this feature increases the control reso-
lution for fine-tuning these higher levels.
