3.3.9 Automatic Noise Suppression (ANS)
The Noise suppression module can remove noise from the microphone signal. To use the ANS, the direct routing of the
microphone input channel should be disabled, and the output of the ANS should be routed to the selected destination in the
matrix.
There is only one noise suppression module in the DSP Controller. Select the channels to be noise cancellation as shown in the
figure.
Suppression level:
There are three levels of noise reduction:
Mild(6dB), Medium(10dB) and Aggressive(15dB).
3.3.10 Matrix
The matrix is the core function for routing inputs and processing functions to the appropriate output. As shown in the figure, the
horizontal direction indicates the input channels, and the vertical direction indicates output channel. One-to-one input to outputs
is the default setting. Click a field to establish the new route and click again to remove it. Right-click to bring up the level control
for the crosspoint. When using automixing, echo cancellation and noise suppression modules use the matrix to route the
processed signal to the wanted output.
