The Automatic Volume Control (AVC) function is used to adapt the volume of a speaker line to the environmental noise. If the noise gets higher the volume will be increased. The goal is that the played messages can be recognized in all environmental noise situations. The message should be not too loud when the noise level is low and could be still heard with a high noise level.
The Cerberus PACE Compact modular system provides 2 components for the Automatic volume control (AVC) function:
- 'Automated volume control microphone', PCA2007-A1
- 'Automated volume control module', PCA2008-A1
