• “GAIN“: this enables you to apply a general gain to the signal. This entails a general
increase of the signal level, which will be especially noted at low input levels that are
under the threshold set. It ranges between 0 and 40dB.
• “OK”: allows you to accept the created or edited configuration. A double confirmation is
required.
• “Cancel”: allows you to reject the created or edited configuration. No change you may
have made is saved.
4.3.4.2. Advanced configuration of Noise Gate.
From the initial screen of the pre-sets advanced information menu (“Digital Sound Processes”)
you can configure and activate/deactivate the Noise Gate operation.
When you select the “Active” checkbox, the “Configure” button gets active and gives you
access to the graphic display where the Noise Gate associated parameters can be modified.
A noise gate is a dynamics processor that lets signals through whose level exceeds a certain
threshold, strongly attenuating the signal levels below that threshold and thus muting noise. It
enables its user to eliminate extraneous noise from a signal source, whether it is background
noise in the studio, in the case of a microphone, or the background noise generated by a
playback device, for example, a tape.
The available controls are:
• “THRESHOLD“: determines the level above which signal is allowed through the gate.
• “ATTACK TIME”: the time for the gate to react to a signal that is exceeding the
threshold.
• “RELEASE TIME”: the time that the gate should remain open once the signal exceeding
threshold has disappeared.
• “HOLD TIME”: the time that the gate should remain open when the signal falls below
the threshold.
• “RANGE”: the limit of dynamic range where created configuration will have effect.
