Auto Noise Gain
Adjust the audio level of the paging input (P.M.) depending of the ambient noise.
The ambient noise is measured with a sensing microphone connected to the sensing microphone
input (S.M.). Our advice is to use the sensing microphone MSN (Ateïs), but you can also use another
one.
•
S.M: sensing microphone input
•
P.M: paging input

Over Indicates the calibration result:
The white noise level needed is over the range.
A pop-up window will shows you what to do.
Under Indicates the calibration result:
The white noise level needed is under the range.
A pop-up window will show you what to do :
Response speed Selector Select here the reaction speed of the A.N.G.
That's means the speed to adapt the P.M. audio level depending of
the ambient noise.
Min Gain -15 to 0 dB The minimum AGC level compensation
Max Gain 0 to 15 dB The maximum AGC level compensation
Sampling time 0.5 to 60 sec Determine the period time between two ambient noise measures
Noise generator Meter White noise level, automatically Adjusted by the calibration
