5.7 Setting up automatic volume control (AVC)
The ↑ AVC monitors the ambient noise level for a single zone. See also
Automatic Volume Control (AVC) settings [➙ 106].
The matrix that takes this measurement is referred to as a noise monitor.
For this feature, the following components are required:
● AVC microphones
● AVC monitoring module
● Speaker line in close proximity to the microphone
These components must be connected to the same 'Digital audio matrix (4/4/4)', or
'Digital audio matrix (4/4/16)', or Cerberus PACE Compact digital audio matrix
board. In case the environment noise exceeds a configurable threshold, a new
AVC attenuation value is calculated and shared in the whole network. Other
network participants can utilize this value to control their output volume.
For this feature to work perfectly, the following points must be
observed:
● Up to four AVC-MIC microphones can be used for a single zone.
● The speakers and microphones must be arranged close to each other.
● The microphones must all be located in a single zone, if possible in the same
room, without interference sound from other zones.
● The microphones must be connected via an AVC monitoring module.
● The AVC-monitoring module needs to be connected to the fourth audio input.
● The audio output which has the speaker line connected is free to choose.
● Only a 'Digital audio matrix (4/4/4)', or 'Digital audio matrix (4/4/16)', or
Cerberus PACE Compact digital audio matrix board is able to monitor the noise
level.
● The microphone input and audio output of the measurement zone need to be
connected to the same device.
● All audio outputs of all 'PACE-Net' devices can be controlled by the AVC values
of a 'Digital audio matrix (4/4/4)', or 'Digital audio matrix (4/4/16)', or Cerberus
PACE Compact digital audio matrix board noise monitor.
● A digital input is required to process errors detected by the AVC monitoring
module.
