DUCKING
Ducking is commonly used for voice-over applications in which the background music
level is reduced automatically when an announcer speaks. When the KEY IN source signal
level exceeds the specified THRESHOLD, the output level is attenuated by a specified
amount (RANGE).

Description
This determines the level of trigger signal (KEY IN)
required to activate ducking.
This determines the amount of attenuation when
ducking is activated.
This determines how soon the signal is ducked
once the ducker has been triggered.
This determines how long ducking remains active
once the trigger signal has fallen below the
THRESHOLD level.
This determines how soon the ducker returns to its
normal gain once the trigger signal level drops
below the threshold. The value is expressed as the
duration required for the level to change by 6 dB.
