Ducking parameters
Ducking lowers the level of microphone or program material (based on a source signal from
another microphone) for the duration of the signal that is present at the source microphone.
It restores the original level after the source signal ceases and after the hold and release
times are met. This is useful when:
• Program material must be attenuated in order to accentuate the voice of a narrator.
• One microphone is used by a chairman or master of ceremonies and must have priority
over other microphones and program material.
A paging microphone must attenuate all other signals.
•
To apply ducking for microphone inputs:
1. Click the
Mic/Line Input
2. From the desired
Mic/Line
The following ducking options become available:
Threshold — Sets the input signal level in dB that the ducking source must exceed
•
before ducking begins. The default is -30 dBFS.
Hold time — Determines the time in milliseconds after a ducking source signal
•
drops below the threshold before ducking ceases. The default value is 1000 ms.
Release time — Determines how long in milliseconds the ducking targets take to
•
restore signal levels after the ducking source level is below the threshold and the
hold time is met.
Duck (targets) — Shows all potential targets to be attenuated when ducking is
•
enabled.
Duck by (attenuation) — Attenuates the corresponding duck target in dB.

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.
