Use the A.N.G
When the calibration green led lit, the system is ready.
In our example, the A.N.G has detected an ambient noise average of -12dB. We choose a medium
"response speed" and a short "sampling time" to be enough reactive quickly.
Now the A.N.G will automatically adjust the level on the (P.M) signal depending on the ambient noise
detected on the sensing microphone.
The A.N.G will working when the paging activity led will light, meaning that an audio signal is
detected on the (P.M) input.
Dead Zone:
If the sensing microphone doesn't detect more noise than during the calibration, the A.N.G works in
the "Dead Zone" which means that there is no need to adjust the gain.
As the noise level is near than during the calibration, the differential level is almost null.
