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.
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.
