Element Description
Bypass: Disable the Ducker's operations.
Active: Light up when the Ducker is activated while the signal has been detected on input S
channel(pin).
Thd.: The threshold of detection on input S channel. The input A channel is attenuated when the
input S channel goes above this threshold.
To avoid the unexpected attenuation, don't set a threshold level too low.
Response Time: Adjust the time between the level detection of input S and the beginning of the
Ducker’s operation on input A channel.
Don't set the "response time" too long, otherwise you won't hear the beginning of input S
channel(as the first word of a speech).
Attack Time: Adjust the fade-in time of input A channel when the Ducker is working.
Hold Time: Adjust the time between the end of level detection on Input S and the end of the
Ducker’s operation.
Set enough "Hold time" to avoid the unexpected background level during the speeches
breaks.
Release Time: Adjust the fade-out time of input A channel when the Ducker is no longer working.
Audio Depth: Adjust the level of input A channel when the Ducker is activated.
Speech Gain: Adjust the level of input S channel when the Ducker is activated.

balances out the signal to make it sound more professional.
