8.14. Auto-Mixing Group Settings
Both the Ducker function (next page) and the NOM Attenuation function (p. 39) are Auto-Mixing Functions that
automatically adjust individual input channel gains in response to input signal level.
The auto-mixing functions can operate in each of the 4 groups, GROUP A through D. Although all the input
channels are grouped into GROUP A by default, they can be individually assigned to the desired groups.
The figure below shows the block diagram of the Auto-Mixing (Auto MIX) section.
[Auto-mixing block diagram]
