Extron electronic DMP 44 LC manual FBy dB, Ducker Configuration, Input Priority

FBy (dB)

Individual attenuation settings for each duck target in dB. The default is 20.0 dB. If additional attenuation of the targets is required, increase this value.

The attenuation range is 80.0 to 0.0 dB in 0.1 dB increments.

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 the example below inputs 2 and 3 are set to duck when input 1 has a signal above the ducking threshold. Input 2 is set to duck input 4.

Notice the priority tree in the illustration below (D). The inputs are arranged by their priority status. Input 1 has inputs 2 and 3 under it, therefore, if input 1 exceeds the threshold, it will trigger inputs 2 and 3 to duck. Similarly, input 2 has input 4 under it. Therefore, if input 2 exceeds the threshold, it will trigger input 4 to duck. Since input 2 has input 4 under it, input 1 triggers inputs 2, 3 and 4.

Figure 17. Ducker Configuration, Input Priority

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.
