“Ducker” component editor
This function reduces the audio signal level (volume) of the input channel when an audio
signal is input to a specific channel. For example if this is used on background music and
the key-in source is assigned to a channel with a mic connected, the background music will
automatically diminish when an announcement is made into that mic, and automatically
return to the original volume when the announcement is over.
1 DUCKER[ON] button
Switches the DUCKER function between enabled and disabled.
2 Ducking curve
This shows the effect as a graph. The horizontal axis is the input signal level, and the
vertical axis is the output signal level.
