12.4. NOM Attenuation Settings
NOM is an acronym of Number of Open Microphones, and represents the number of microphones in open
status (the number of input channels with open gates).
The NOM attenuation function automatically adjusts the open microphone's input channel gain depending on
the number of open microphones. The open microphone channel gain is attenuated by the gain set on the
following setting screen each time the number of open microphones doubles. The use of this function allows
an output level to be kept constant, thus helping to prevent feedback. Set each input channel to enable or
disable this function. (Refer to p. 39.)
This function operates in each of the auto-mixing groups, GROUP A through D (p. 37).
