Automixer and
Bus Mixer
Settings
To operate the Vortex device in any of the above possibilites, two global parameters
need to be changed: the A
need to be changed: the A
UTOMIXER
and the B
US
M
IXER
(see Figure 14). The A
UTO
-
MIXER
parameter chooses which automixer the input channel will be on (this is
changed either on the A
UTOMIXER
page in Conference Composer or on the M
ATRIX
M
IXER
page).
The B
US
M
IXER
parameter is used to assign one of the two internal automixers to one
of the EF Bus automixer groups. For example, consider three Vortex devices, each of
which has 2 microphones assigned to Automixer 1 and 2 microphones assigned to
Automixer 2. Now, if each of these devices sets their Automixer 1 to have Bus ID 5,
then the three automixers (one from each device) will work as a single automixer con-
taining 6 (3 x 2) microphones. Setting B
which has 2 microphones assigned to Automixer 1 and 2 microphones assigned to
Automixer 2. Now, if each of these devices sets their Automixer 1 to have Bus ID 5,
then the three automixers (one from each device) will work as a single automixer con-
taining 6 (3 x 2) microphones. Setting B
US
M
IXER
to 0 means that the automixer is
not grouped on the EF Bus.
Operating as an
Independent
Automixer
To set the Vortex device to operate as an independent automixer (or two), set the B
US
M
IXER
parameter to 0, or to a number that is different from any other automixer group
on the EF Bus.
Operating as One
Automixer with
Multiple Vortex
Devices
To set the Vortex device to operate as one automixer across several devices, set the
B
B
US
M
IXER
parameter on all devices to the same automixer group.
Default Settings
In the default preset (Preset 0), the Bus Mixer for Automixer 1 is set to 1 and the Bus
Mixer for Automixer 2 is set to 2. This means that in the default mode, all linked
devices will work together as one complete automixer.

The following is a checklist for building a system with mutliple devices:
1. Assign Inputs.
2. Assign Outputs.
3. Configure submatrix (the EF Bus).
4. Configure your echo canceller reference.
