Priority
In some cases, multiple levels of ducking can be required to enable an input source to take
precedence over all but one other input.
In this example, Inputs 2 through 6 are set to duck when Input #1 has a signal above the
ducking threshold. Input #2 is set to duck inputs 5 and 6. Since Input #1 has previously
been set to duck Input #2, Input #1 is disabled to prevent contradictory priorities.
Figure 35. Ducker Configuration, Input Priority
Notice the priority tree on the right side of figure 35. 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 through 6 to duck. If Input #2 detects a signal and there is no signal on Input
#1, Input #2 will trigger inputs 5 and 6 to duck. However if the Input #1 signal exceeds the
threshold, it will then duck all inputs including Input #2.
NOTE: 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 that set
for the individual input and virtual send in the "by (dB):" column near the center of
the dialog box.
