Trigger Button
This toggles the trigger source
between left and right channels,
right channel only, and left
channel only.
Use Right or Left Channel
as external key source
input. An external audio
source may be used to
control the gate action making it possible to gate one sound
according to the dynamics of another independent signal.
Key Listen (Noise Gate/Expander)
When this switch is set to Key Listen, the effect of the key
filters on the program material is heard at the output. In normal
operation (Key Listen Off), the filters only affect the way the
Noise Gate responds to the incoming program material—they do
not have a direct effect on the output signal e.g. try getting a
long sustained ‘strings’ sound with a highhat signal...
Active Button
The Active button enables the Noise Gate. The Active button
(when off) routes the input signal past the noise gate module
without processing.
Key Filter (Noise Gate/Expander)
The Low-Frequency filter is variable from 15.6Hz to
22.6kHz and works by severely attenuating frequencies below
the cut-off frequency selected.
The High-Frequency filter is variable from 15.6Hz to 22.6kHz.
This filter attenuates the frequencies above the selected cut-off
value. When both filters are set, the range between the two
settings is allowed to pass as through a band-pass filter.
Note: Any side-chain filtering which implements high-frequency attenuation will
also cause a slight delay in the time the gate takes to trigger. Under most circum-
stances this will be quite imperceptible, but when transient sounds are being
processed with the high-frequency control set to a very low value, some degrada-
tion of the attack transient may become apparent. For this reason, always set the
high-frequency control to the highest possible value practicable when processing
percussive sounds.
