Key Listen When enabled, this lets you listen to
the reference track controlling the side-chain in-
put. This is often useful for fine tuning the Lim-
iter’s settings to the Key Input. Key Listen audi-
tions the right audio channel on RTAS and
AudioSuite versions of the Limiter.
Gate II
The Gate (also known as a noise gate) lets a sig-
nal above the selected threshold pass through to
the output at unity gain, without dynamic pro-
cessing. Once the input signal falls below the
threshold level, the gating shuts down the sig-
nal by fully or partially attenuating the output.
In this way, the desired signal is allowed to pass,
but unwanted signal is not. The Gate is useful
for noise removal on individual tracks, and can
be used for special effects such as cutting off a re-
verb tail.
Gate Controls
Phase Invert Inverts the phase (polarity) of the
input signal to change the frequency response
characteristics between multi-miked sources or
to correct for miswired microphone cables.
Gating Indicates the amount of reduction in dB.
Threshold Sets the threshold level. Signals that
exceed this level will pass through. Signals that
are below it will be gated, depending on the set-
tings of the Attack, Hold, Decay, and Range con-
trols (explained below).
Attack Sets the attack time of the Gate.
Hold Specifies a duration (in seconds or millisec-
onds) that the Gate will stay open after the ini-
tial attack cycle. This can be used as a one-shot
function to keep the Gate open for longer peri-
ods of time with a single crossing of the thresh-
old. It can also be used to prevent gate chatter
that may occur if varying input levels near the
threshold cause the Gate to open and close very
rapidly.
Decay Controls how long it takes for the Gate to
close after the signal falls below the threshold
level.
Range Sets the depth of the Gate when closed. It
has a maximum depth of –80 dB. Setting the
gate to higher range levels allows more of the
gated audio that falls below the threshold to
peek through the gate at all times. This is useful
for things such as drum leakage, where you may
want to suppress the overall drum kit sound by
a specific amount, while emphasizing the gated
instrument such as a snare.
Graph Displays the response curve set by the
Gate’s Threshold and Range settings. As you ad-
just these controls, refer to the graph to see how
the shape of this curve changes.
Key Listen settings are not saved with other
plug-in settings.
