Priority
In some cases, multiple levels of ducking may be required enabling an input source to take
precedence over all but one other input.
In this example inputs 2-6 are set to duck when Input #1 has a signal above the ducking
threshold. Input #2 is set to duck inputs 5-6. Since Input #1 has previously been set to
duck Input #2, Input #1 is disabled (grayed out) to prevent contradictory priorities.
Figure 27. Ducker Configuration, Input Priority
Notice the priority tree on the right. The inputs are arranged by their priority status.
Input #1 has all other ducked inputs under it, therefore if a signal is detected, it will
trigger Inputs 2-6 to duck. If Input #2 detects a signal and there is no signal on Input
#1, Input #2 will trigger inputs 5-6 to duck. However if the Input #1 signal exceeds the
threshold, it will then duck all inputs including Input #2. Ducking attenuation is not
additive. When an input target is ducked, regardless of how far down the priority line it is,
the maximum attenuation is what is set in the "by:" column near the center of the dialog
box.
