A pass filter like the Noise Gate is described by its cut-off point and slope. The cut-off point is the frequency where high or low-frequencies will be removed. The slope, given in decibels per octave, describes a ratio of how the filter attenuates frequencies past the cut-off point (eg. 12 dB per octave).

One cause of feedback is open microphones on the stage. You can use the Noise Gate in ToneMatch mixer to shut down microphones that are not actively being used.

You can use the Comp/Gate Noise Gate to automatically turn off a microphone when it is not being used. This can reduce unwanted background noise and increase the gain-before-feedback of your system. The Noise Gate prevents signals below a certain volume level from reaching the outputs of the mixer. You set that certain volume level by setting the Threshold.


  1. Press the CHEDIT button on the channel you want to control
  2. Turn the Rotary Selector to COMP/GATE
  3. Under the display, turn the Type button so you can see the menu
  4. Select Noise Gate
  5. Set the Thresh to -40.0dB
  6. Leave Ramp/Speed at 50%

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.

Here's a quick video to show you how to do it.

A pass filter like the Noise Gate is described by its cut-off point and slope. The cut-off point is the frequency where high or low-frequencies will be removed. The slope, given in decibels per octave, describes a ratio of how the filter attenuates frequencies past the cut-off point (eg. 12 dB per octave).
