Ducking Configuration Dialog
a
Current source indicator
Shows the selected input. Ducker settings affect the input channel shown here. When a ducker
dialog is opened for a channel, the current source defaults to that channel. The current source can
also be selected via the priority readout/source selector (see below).
b
Enable mic/line source checkbox
When checked, ducking is enabled for the current source and the ducker processor block is lit. When
unchecked, ducking is disabled for the current source and the ducker processor block is unlit.
c
Duck Targets:
Shows all potential input targets. Only inputs that are checked will be ducked. The current source is
not available as a target (a source cannot duck itself). If the current source has been designated as a
target of another input channel, that input channel is not available (a target cannot be the source).
d
Settings:
Used to configure the parameter settings for the ducker source. When a ducker block is copied,
these settings are transferred.
Threshold — Sets the input signal level, in dB, the ducking source must exceed before ducking
begins. If ducking does not occur soon enough to avoid loss of speech or program material from
the ducking source, decrease this setting. If ducking occurs too soon, allowing background noise to
trigger ducking, increase the setting.
The range is -60 to 0 dB in 1 dB increments. Default is -30 dB.
Attack Time — Adjusts the time to duck the targets once the threshold is exceeded.
The range is 0 to 3000 milliseconds in 1 millisecond increments. Default is 1 millisecond.
Hold Time — Determines the time, in milliseconds, after a ducking source signal drops below the
threshold before ducking ceases.
The range is 0 to 10000 milliseconds in 1 millisecond increments. Default is 1000 milliseconds
(1 second).
Release — Determines how long, in milliseconds, after the ducking source level is below the
threshold and the hold time is met, the ducking targets take to restore signal levels.
The range is 10 to 10000 milliseconds in 1 millisecond increments. Default is 1000 milliseconds
(1 second).
e
Priority
Displays the hierarchy of ducking source to duck targets. Priority levels are displayed in tree fashion.
Input channels that are targets being ducked by a source are shown as indented below the source.
Any input channel displayed in the tree is an active link. Click any input channel to select that
channel as the current source. The current source indicator ( a ) reflects the selected input channel.
f
By: (Target gain reduction amount)
Individual attenuation settings for each duck target in dB. The default is 20.0 dB. If additional
attenuation of the target(s) is required, increase this value.
The attenuation range is 80.0 to 0.0 dB in 0.1 dB increments.
g
Mix Status (for virtual returns):
Indicates whether the source is being routed to the virtual sends. This is a readout value only, shown
for convenience during ducking configuration.
