by (dB): — Individual attenuation settings for each duck target indB.
The default is 20.0dB. If additional attenuation of a target is required, increase
this value. The current source setting is not available.
The attenuation range is 80.0 to 0.0dB in 0.1dB increments.
5
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 (see
1
on the previous
page) reflects the selected input channel.
6
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 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.
Range: -60 to 0dB in 1dB increments.
Default: -30dB.
• Attack Time — Adjusts the time to duck the targets once the threshold is
exceeded.
Range: 0 to 3000 milliseconds in 1 millisecond increments.
Default: 1millisecond.
• Hold Time — Determines the time, in milliseconds, after a ducking source signal
drops below the threshold before ducking ceases.
Range: 0 to 10000milliseconds in 1 millisecond increments.
Default: 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.
Range: 10 to 10000 milliseconds in 1 millisecond increments.
Default:1000milliseconds (1second).

AM Group — Assign the channel to a gating group.
Selections are 1 through 8. Default is None.

Show AM Group Details — Opens a dialog box
that details current groups and the parameter member
assignments to each (see Automix Group Details on page 144 for particulars).
