8.13. AMBUSID -- Set Automixer Groupings for EF Bus
This command is used to assign one of the two internal automixers to one of the EF Bus automixer groups. 
For example, consider three EF2241's, each of which has two microphones assigned to Automixer 1 and two 
microphones assigned to Automixer 2. Now, if each of these EF2241's sets their Automixer 1 to have Bus ID 
5, then the three automixers (one from each EF2241) will work as a single automixer containing 6 (3 x 2) 
microphones. Setting AMBUSID to 0 means that the specified automixer is not grouped on the bus. 
The first argument in the AMBUSID command is the automixer number (1 or 2) and the second argument is 
the Bus ID (0 for none, or 1 through 8). Although this command is a channel integer command, use of the 
wildcard character for the automixer number is not supported. 
This command is a channel integer command. See 
Section 6.3 and Section 6.2 for more information on this 
type of command. The minimum and maximum values for this command are 0 and 8, respectively. 
This command is saved to non-volatile memory only as part of a preset. The state of this command will be 
restored after power-up only if a preset is saved and that preset is set to be the power-on preset. 
Example Description Status Message

Bus Automixer having Bus ID 2. 
B01AMBUSID12
B01AMBUSID20

Bus Automixer having Bus D 0. This 
means that the automixer is not part of 
any Bus Automixer.
