The AVC basic principle is using one or more microphone(s) to measure the ambient noise level and compensate the speaker output.
This will ensure that the volume of the message will be over the ambient noise level.
The reason for using AVC is to adjust the output audio from an amplifier based on ambient noise in the area. This is typically used on railway stations, metro stations, ropax and cruise vessels.
Availability
This function is available from Exigo 1.3.3.1 and newer.
