Ducking Configuration Dialog

ACurrent 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 the following figure).

BEnable source mic/line 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.

CDuck

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).

DSettings

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 release time engages.

The range is 0 to 10000 milliseconds in 1 millisecond increments. Default is 1000 milliseconds (1 second).

Release — Determines the time, 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).

EPriority

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.
