Dynamics
Separate “soft-knee” compressor/limiter and expansion/gate modules are
available in the dynamics section. Each module has their own set of controls.
Important: Dynamics are not processed unless enabled by the Dynamics
selector buttons ( “Dynamics In (DYN IN)” on page 529 ).
Compressor/Limiter
Link When UAD SSL E Channel Strip is used in a stereo-in/stereo-out
configuration, two separate dynamics processors are active (one
for each stereo channel). When Link is engaged, the two compres-
sors are constrained so that they both compress by the same
amount at any instant.
This prevents transients which appear only on one channel from shifting the
stereo image of the output. Any big transient on either channel will cause both
channels to compress.
Link is active when its amber LED is illuminated. When the plug-in is used in
a mono-input configuration, Link has no affect.
Compress Ratio Ratio defines the amount of gain reduction to be processed
by the compressor. For example, a value of 2 (expressed as
a 2:1 ratio) reduces the signal above the threshold by half,
with an input signal of 20 dB being attenuated to 10 dB.
The UAD SSL E Channel Strip compressor offers a continu-
ously variable ratio between 1:1 (no compression) and infin-
ity:1 (limiting).
Note: Signals must exceed the Threshold value before they are attenuated by
the Ratio amount.
Compress
Threshold
Threshold defines the signal level at which the onset of com-
pression occurs. Incoming signals that exceed this level are
compressed. Signals below the level are unaffected.
The available range is +10 dB to –20 dB. Rotate the control
clockwise for more compression.
