8.9. AMNOMAT -- Select NOM Attenuation on Each Output
This command enables, disables, or queries NOM attenuation for the specified output . (A, B, T). NOM
attenuation is calculated as 10*log(Number of Open Microphones).
Remember that even though there are no microphones on this device, other microphones can be
brought in via the W, X, Y, and Z busses. These signals will have NOM information carried with them
from the other devices, which is why NOM attenuation is provided at the outputs.
This command is a channel boolean command. See
Section 6.3 and Section 6.1 for more information on
this type of command.
This command is saved to non-volatile memory only as part of a preset. The state of this command will
