As simple example, we will set a system for a speaker with background music. When the speaker
is talking, the background music must decrease its level.
The speaking is using a standard dynamic microphone type SM58. The microphone is connected to
the channel 2 of the "Input A" component, with a input sensitivity at -40dB (set in the input A
component). Then the microphone is linked to the input (S) of the Ducker.
The music player (as a CD player) is connected to the input 1 of the "Input A" component. Then the
music is linked to the input (A) of the Ducker.
Elements:
Threshold
Set at -18dB, because less would active the attenuation when the speaker is not talking if the
microphone catch some unexpected noise.
Response Time
Set very short, because the background music must be attenuated as soon as the speaker is
talking.
Attack and Release Times
Which are the "fade in" and "fade out" on the background music. Set almost one second for the
hearing comfort, we want a kind music transition.
Hold Time
Set at 700(ms), enough to avoid the music back during the speech breaks.
Audio Depth
Set at -20dB, to hear the music during the speech, but at very low level (depending of the
context).
