6.2.6.2 MAM

'Moving Attenuation Mode' (MAM) enables the AVC value to be set up as a

follower. The measured level and a given AV offset value are used for the

calculation.

Fig. 62: AVC settings: Moving Attenuation Mode

In MAM mode, the 'Release' parameter is not valid and is used as an AV offset

value. The release rate corresponds to the 'Attack' parameter, meaning that the

release rate is the same as the attack rate.

Averaging time is multiplied by 100 to reach a resolution of 100 ms instead of the

standard resolution of 1 ms if MAM is not active. Therefore the range of averaging

time is 1…25.5 seconds.

'Skip Calls'

Used to skip the calculation of the AVC value while

announcements are running. The AVC value before the announcement started is

frozen and used

while the announcement is active.

'Skip use IO'

This flag is visible if the 'Skip Calls' function is active. Depending on the state of the

configured digital input, the calculation is skipped and the AVC value is frozen

while an announcement is running.

'IO Triggered'

Usable if 'IO Triggered' is active and 'Skip Calls' is deselected.

For the 'IO Triggered' setting, the digital input 1…8 is selected. Otherwise use the

fixed analog input 4 for the AVC microphone.

The meaning and behaviour of this flag is changed in the following manner if Skip

Calls flag is active: Additionally to present priority calls, the selected input is used

to freeze calculation of the AVC value.
