Damp – signal attenuation control
Use the Damp knob to control how strongly
Sentry Noise Gate should attenuate the output
signal when the input signal falls below the set
Threshold.
►
Set the Damp knob to maximum position to
have the gate close completely (i.e., mute the
signal at the output) when the gate has been
triggered.
►
Set the Damp knob to a lower position to only
attenuate the signal at the output when the
gate is triggered. Lower settings will lead to
more organic, natural sounding results.
Now you might think that a noise gate should al-
ways have a maximum effect when triggered. Af-
ter all, you want to remove unwanted noise! But
consider that the transition between the "open"
stage and the "gated/attenuated" stage should
usually be imperceptible. The stronger the atten-
uation, the more obvious the effect of the noise
gate will be. Experiment to achieve the right bal-
ance between "effective" and "subtle".

Decay – gate decay control
Use the Decay knob to control how quickly Sen-
try Noise Gate should attenuate the output signal
when the input signal falls below the set Thresh-
old.
►
Turn the Decay knob to the right for a long
decay.
► Turn the Decay knob to the left for a short de-
cay.
A shorter decay will eliminate noise more effec-
tively, but also be more noticeable. Again, you
should experiment to find the right balance.
Inputs, outputs and controls
Gate type selector
Use the Gate type selector to select the desired
noise gate type.
Gate setting
To operate Sentry Noise Gate as a traditional
single band gate, set the Gate type selector to
"Gate".
TonePrint setting
To use TonePrint-based noise gate configura-
tions, set the Gate type selector to "TonePrint".
For more information, see "TonePrint".
Hiss setting
To operate Sentry Noise Gate in hard gate mode,
set the Gate type selector to "Hiss". This is a
multiband gate mode that is especially suited
(you guessed it) for eliminating hissing.
Why use multiband gating?
Splitting an audio signal into several frequency
bands before running it through a noise gate al-
lows the gate to work more effectively. Think of
a multiband noise gate as multiple units target-
ing and processing low, mid and high frequency
ranges independently and efficiently.
