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
UTOMIXER and the BUS MIXER (see Figure 14). The AUTO-
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 MATRIX
M
IXER page).
The B
US MIXER 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
US MIXER 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 BUS
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
US MIXER 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.
C ONFIGURE THE M ATRIX M IXER
The matrix mixer allows arbitrary crosspoint gains in 1 dB increments between any
input and output signal.
If you have a PC, use the Conference Composer software (See the Conference Com-
poser User Guide) to set the matrix parameters. If you would like to set matrix
parameters from the LCD menus, see “Matrix Menu” on page 34 for descriptions and
instructions on setting matrix mixer parameters.
B UILDING Y OUR S YSTEM WITH M ULTIPLE V ORTEX D EVICES
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.
