For most noise removal applications, set the
Threshold as low as is possible, so that none of
the desired signal is lost.
Attack Control
The Attack control sets the rate at which the
Gate opens from a closed state. Attack ranges
from 20 µS (about 1 sample) to 1.7 seconds.
A very fast attack time can sometimes produce
audible clicks on low frequency signals.
Hold Control
The Hold control determines the amount of
time the Gate is held open after the signal falls
below the Threshold setting. Hold range is from
2 ms to 2.2 seconds. Hold helps prevent spuri-
ous re-triggering of the Gate when using fast re-
lease times. It is also useful for creating the clas-
sic gated reverb sound often applied to drums.
The Hold cycle starts when the Threshold is
crossed. Audio material with slow attacks re-
quires the Hold setting to be at least as long as
the Attack setting for it to complete its attack cy-
cle.
Release Control
The Release control determines the speed at
which the Gate closes to the Range setting after
the input signal has fallen below the Threshold
level. Release range is from 1 ms to 9 seconds.
Longer releases help retain the original enve-
lopes of the gated audio.
Range Control
The Range control sets the level to which the
Gate closes after the input signal has fallen be-
low the Threshold setting.
The range is from 0 dB (no gating) to infinity
(fully gated, or no signal).
When Ducking is enabled, the Range control
sets the level to which the signal will be reduced
when open (triggered). For Ducking set this be-
tween –3 dB and –12 dB.
Gate/Duck Control
This toggle switch selects the Gate’s mode of op-
eration. In Gate mode, a signal above the
Threshold will cause the Gate to open. In Duck
mode, the audio passes unattenuated until the
signal exceeds the Threshold. Ducking is mainly
for applications such as voice-overs or removal
of pops and clicks.
Bypass Control
The Bypass control bypasses the Gate.
Gate Envelope LED Meter
This traffic light-style LED shows the active state
of the Gate envelope:
• When the Gate is closed, the red LED is lit.
• When the Gate is open, only the green and
yellow LEDs are lit.
• When the input signal falls below the
threshold, the yellow LED will light then
fade over the duration of the release time.
In Duck mode, the green LED indicates an un-
triggered (resting) state.
