Level:
There are six level options. The amount of noises suppressed by Level 1 is -9dB. For Level
2/3/4, the amount of noises suppressed by each level decreases by 3dB progressively. For Level
5/6, the amount of noises suppressed by each level decreases by 6dB progressively. The
maximum suppression is -30dB.
7.2.2.13 Ducker
The Ducker has two main signal sources, one is the control signal is also called the dodge
signal, the call signal, one is the controlled signal also called the flash signal, the background
signal. The main function of the dodge is to select a certain input signal as a control signal, it
will reduce the effect of the controlled signal, mainly used in conference rooms, shopping
malls and other occasions.
Scenario 1:
Select the sound input from the rostrum as a control signal. When the main
speaker speaks, it will reduce the volume output (controlled signal) of other personnel, so as
to achieve the effect of only one speech. Scenario 2: Play the background music, but when
there is a notice or prompted the need to play, the concert in the vocal (call signal) inserted
automatically shut down, after the disappearance of human voice and then automatically
resume, then the Ducker in the work.
The control signal (flash signal, background signal) of the dodge shown in the figure above is
the default output signal of the feedback cancellation module as the source of the signal.
The simplified operation in the figure is not directly displayed.
In the above dodge input, select the input channel as the dodge signal (eg, the above
control signal, dodge signal, call signal).
Bypass:
The input signal is bypassed and no dodge processing is performed.
Threshold:
Dodge the starting level, when the control signal is higher than this limit, it will
start dodge processing module, the controlled signal to dodge.
Depth:
When the control signal exceeds the set threshold, the range of this value can be
