Noise Gate: Difference between revisions - Bose Portable PA Knowledge

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 '''Thresh'''old.

# Press the '''CHEDIT''' button on the channel you want to control

# Turn the Rotary Selector to '''COMP/GATE'''

# Under the display, turn the Type button so you can see the menu

# Select '''Noise Gate'''

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

# 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.

One cause of feedback is open microphones on the stage. You can use the T1 ToneMatch® audio engine <strong>Noise Gate</strong> to shut down microphones that are not actively being used.  Here's a quick video to show you how to do it.
