Enable AGC: Check the box to enable automatic volume control. Volume is adjusted according to the ambient noise level. The AVC will perform better if the loudspeaker volume is set to a fairly low level, as this will give the AVC a more dynamic range for adjustments. Note that the AVC adjustment is disabled while the speaker is playing audio. Adjustments are made in silent periods (min. 100 ms silence required).

AGC mode: Check to open for more advanced AVC settings
AGC gain profile: Threshold level for the AVC to start working. Valid range: 30-80 dBA. Default is 55 dBA.
AGC speed: Threshold level for the AVC to stop working. Valid range: 60-120 dBA. Default is 100 dBA.
