6.9Adjusting Noise Gate Settings

A noise gate controls the volume of an audio signal by attenuating by a fixed amount the signals that register below the threshold.


To adjust the noise gate settings for a channel:

Step 1On the appliance Web UI’s main page, select DSP.

Step 2Select the Menu button for the channel.

Step 3From the drop-down menu, select Noise Gate.

Note: If you want to return to the factory settings, select the Reset icon that appears in the right corner.

Threshold

Sets the threshold level that the signal must be below for the noise gate to “close” (pre­vent the sound from getting through). Threshold range is -135 to +21 db.

Attack

Adjusts how long it takes for the gate to open once the signal falls below the thresh­old. Attack range is 1 to 500 ms.

Hold

Defines the length of time the gate will stay fully open after the signal falls below the threshold. Hold range is 1 to 500 ms.

Decay

Sets the rate for turn off of the gate after the signal is below the threshold. Decay range is 0 to 2000 ms.
