Ducking Configuration Dialog
Ducking is configured in a dialog box which opens when an active ducking processor block is
double-clicked.
a
Current source indicator
Shows the input selected as the ducking
source. 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 cleared, 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
by: (Target gain reduction amount)
Individual attenuation settings for each duck
target indB. The default is 20.0dB. If additional
attenuation of a target is required, increase this
value.
The attenuation range is 80.0 to 0.0dB in 0.1dB increments.
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 an input
channel to select that channel as the current source. The current source indicator (
a
) reflects
the selected input channel.
f
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, indB, the ducking source must exceed before
ducking begins. If ducking does not occur quickly 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 0dB in 1dB increments. Default is -30dB.
