8.12. AMAUTO -- Select Automatic or Manual Gating for
each Automixer Input
This command selects or queries the state of automatic or manual automixer gating thresholds for the
specified input channel. Automatic thresholds mean that the automixer adaptively determines the
gating thresholds based on current speech and noise levels using the gating ratio specified by the
AMGATER command. Manual thresholds mean that the automixer uses the absolute threshold set via
the
AMGATET command.
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 be restored after power-up only if a preset is saved and that preset is set to be the power-on
preset.

8.13. AMBUSID -- Set Automixer Groupings for EF Bus
This command is used to assign the internal automixer to one of the EF Bus automixer groups. For
example, consider three EF2211's, each of which has its automixer enabled for its microphone input
(input 1). Now, if each of these EF2211's sets its automixer to have Bus ID 5, then the three
automixers (one from each EF2211) will work as a single automixer containing 3 (3 x 1) microphones.
Setting AMBUSID to 0 means that the specified automixer is not grouped on the bus. For compatibility
with EF2280 and EF2241 commands, the AMBUSID command requires you to specify the automixer
number with the command. On the EF2280 and EF2241, there are two internal automixers. However,
the EF2211 only has one internal automixer, so 1 is always specified.
The first argument in the AMBUSID command is the automixer number (always 1 for the EF2211) 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.
