6.7Ducker
Ducking is an audio effect in which the level of one audio signal is reduced by the presence of another signal. For example, if background music is playing when a page is made, the ducker will sense the presence of audio from a paging microphone and trigger a reduction in the output of the music signal for the duration of the page. The ducker restores the original level for the background music once the page is over.
To adjust the ducker settings for a channel:
Step 1On the appliance Web UI’s main page, select DSP.
Step 2Select the Menu button for the channel or select the Menu button for the Output.
Step 3From the drop-down menu, select Ducker.
Note: If you want to return to the factory settings, select the Reset icon that appears in the right corner. |
Step 4Make desired adjustments using the controls described in the following table:
Threshold |
Sets the threshold level, or how loud the signal has to be, before ducking is enabled. The range is -135 to +20 dB. |
Hold |
Sets how long the master continues to duck the signal after the signal is below the threshold. The range is 1 to 500ms. |
Master |
Select the channel that serves as the master, or unducked, channel. The audio on this channel has priority; audio for all other channels is ducked. |
Ducked |
Select the channel or channels that will be ducked when the threshold is reached on the master channel. |
