Ducking (DUCK)
Ducking provideds a means to duck, or lower, the level of one or more
input signals when a specified source must take precedence. The
ducking processor block, when inserted, provides a means to duck one
or more mics and program material (ducking targets) when the processor detects a signal
from the ducking source. Ducking lasts for the duration of the intertrupting signal (ducking
source) determined by the threshold setting (plus hold and release time) and restores the
original levels of the ducked inputs once the other signal has ceased.
Ducking can be useful when:
• Program material needs to be attenuated in order to more clearly hear a narrator
voice.
• One microphone, such as one used by a master of ceremonies, needs to have priority
over other mics, program material, or both.
• A paging mic needs to attenuate all other signals.
All ducking processor blocks are controlled by a common dialog box that opens when any
of the ducking blocks are selected (see figure 37). All empty ducking processsor blocks
have no ducking source or target settings by default.
When the first ducking processor is inserted, that input is automatically set to
Enable
Mic/Line Source . All inactive ducking processor blocks have Enable Mic/Line
Source unchecked by default.
Figure 37. Ducker Configuration Dialog
Any of the six inputs can be ducking sources. Any or all of the remaining inputs and virtual
sends can be targets.
