To set the EF2280 to operate as an independent automixer (or two), set the B
M parameter to 0, or to a number that is different from any other automixer group
IXER
on the EF Bus.
To set the EF2280 to operate as one automixer across several EF2280s, set the B
M parameter on all EF2280s to the same automixer group.

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
EF2280s will work together as one complete automixer.

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.

The following is a checklist for building a system with mutliple EF2280s:
1. Assign Inputs.
2. Assign Outputs.
3. Configure submatrix (the EF Bus).
4. Configure your echo canceller reference.
Assign each audio source to an input. Remember to include the conferencing equip-
ment such as the EF200 Phone Add or a video codec and any program audio.
Try to assign as many outputs as you can to each EF2280 to make a simpler subma-
trix. Remember that Outputs 1-8 can also be used as outputs of the matrix. The bus-
sing can get very complicated very quickly if you choose to spread your outputs over
several units.
To link multiple EF2280 devices together, use the submatrix on the EF Bus.
