Gain
The Gain control lets you boost overall output
gain to compensate for heavily compressed or
limited signals.
This control ranges from 0 dB (no gain boost) to
+40 dB (loudest gain boost), with the default
value at 0 dB.
Side-Chain Section
The side-chain is the split-off signal used by the
plug-in’s detector to trigger dynamics process-
ing. The Side-Chain section lets you toggle the
side-chain between the internal input signal or
an external key input, and tailor the equaliza-
tion of the side-chain signal so that the trigger-
ing of dynamics processing becomes frequency-
sensitive. See “Using the Side-Chain Input in
Dynamics III” on page 76.
Expander/Gate III
The Expander/Gate plug-in applies expansion or
gating to audio material, depending on the ratio
setting.
About Expansion
Expansion decreases the gain of signals that fall
below a chosen threshold. They are particularly
useful for reducing noise or signal leakage that
creeps into recorded material as its level falls, as
often occurs in the case of headphone leakage.
About Gating
Gating silences signals that fall below a chosen
threshold. To enable gating, simply set the Ratio
and Range controls to their maximum values.
Expanders can be thought of as soft noise gates
since they provide a gentler way of reducing
noisy low-level signals than the typically abrupt
cutoff of a gate.
For more information on the LFE channel,
refer to the Pro Tools Reference Guide.
