# Select '''Noise Gate'''

# Set the Thresh to '''-40.0dB'''

# Leave Ramp/Speed at '''50%'''

# (T4S/T8S) Leave Ramp/Speed at '''50%''' (T4S/T8S)

If you find this cuts off the microphone even while you are speaking directly into the microphone try setting the Thresh to -50.0dB. You may have to experiment with the Thresh to get the Noise Gate to work with different vocalists.

If you find this cuts off the microphone even while you are speaking directly into the microphone try setting the Thresh to -50.0dB. You may have to experiment with the Thresh and Speed to get the Noise Gate to work with different vocalists.

Notes

:Noise Gate: Rotate the Thresh control to adjust the input threshold (trigger) level from –90 dB to –30 dB.

:Rotate the Speed control to set the gate closing speed to any value from 0% (fastest) to 100% (slowest).

:Rotate the Ramp control to adjust the slope of the gate from 0% (horizontal) to 100% (vertical).

:(T4S/T8S) Rotate the Ramp control to adjust the slope of the gate from 0% (horizontal) to 100% (vertical). The Ramp parameter is the slope of the opening gate allowing signal through. It can be thought of and perceived through time. A steep ramp (100%) will open quick and aggressively, while a shallow ramp (0%) opens slow and more gradually. This is different than Speed which affects how quickly the gate clamps down after the signal has passed.

<!--

<br>The Ramp/Speed describes a ratio of how the noise gate attenuates the sound once the threshold has been reached (how quickly the reduction is applied).
