T he gate threshold level is also indicated by the green arrow
above the gate input meter. You can adjust the threshold
level using this indicator as well as by using the “Thres”
knob.
A TTACK CONTROL
T he “Attack” knob allows you to adjust how quickly the gain
reduction is decreased to 0 dB when the detector level goes
above the threshold level. When this control is set to Auto,
the attack rate is controlled by how much the detector level
is above the threshold. When you set the attack to another
value other than “Auto” that value, measured in millisec-
onds, will control how quickly the gate opens. The maxi-
mum value is 100 milliseconds. Attack times other than auto
are especially useful when using the gate as a trigger. If the
key signal is a little early you can use the attack to delay the
trigger slightly. It is also useful to remove the initial transients
of impulsive sounds.
R ELEASE CONTROL
The “Release” knob controls the release time of the gate. This
parameter is measured in milliseconds and can range from 5
ms to 5 sec. The release time controls how quickly the gate
closes after the detector drops below the threshold value. For
settings below 90 ms or so the gate closes pretty abruptly
and may introduce unwanted artifacts into your audio,
depending on the signal.
U SING THE S IDECHAIN K EY INPUT W / SELECTABLE FILTER
The gate provides a sidechain that processes audio before
the detector determines the current level. The sidechain can
