Ducker
Ducker
The ducker provides an easy way to use the DFR22 in an audio system that requires paging. When a paging signal is
present, the ducker attenuates or “ducks” other signals.
Function
Place the ducker on an input channel strip to designate it as the paging signal. When the paging signal exceeds
the specified threshold, the ducker attenuates any other signals that are present at each output mix point to which
it is connected. It does not attenuate signals at a mix point to which the paging signal is not connected. You can
route the paging signal to output channels in the signal flow diagram, the “Matrix Mixer” window, or by checking the
[Paging Channel] check boxes in the “Ducker” window.

DUCK Ducker
Note:
The ducker can only be placed on an input channel strip. Do not place more than one
ducker on the same channel. To prevent extraneous noise on the paging input from
being audible, place a gate ahead of the ducker in the signal flow diagram.
