8.10. 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 EF2280's, each of which has four microphones assigned to Automixer 1 and four
microphones assigned to Automixer 2. Now, if each of these EF2280's sets their Automixer 1 to have Bus ID 5,
then the three automixers (one from each EF2280) will work as a single automixer containing 12 (3 x 4)
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.
