Automixer
One of our design requirements was to make all Vortex devices operate as one 16-channel automixer in
order to limit the maximum number of open microphones to 4 across both units. In order to achieve that,
we need to set the G

NOM to 4 as well. The difference between the Local Max NOM and the Global Max NOM is that the Local
NOM refers to the number of microphones that can gated on within a single unit. The Global NOM refers
to the number of microphones that can be gate don across both units.

The Bus Mixer is set to 1 in each unit. The Bus Mixer refers to the ability of each unit to send and receive
the Automixing information from each unit over the EFBus. In order for both units to function as one
automixer, the Bus Mixer ID needs to be set to the same value. In this case, the default is 1. A Bus Mixer
ID of 0 means that each unit will function as a separate Automixer and that unit will not send its automixer
information to any other linked unit(s).

EFBus
The default routing of the EFBus will not satisfy our design. We will need to make our own custom mixes
to satisfy the requirement of reinforcing certain groups of microphones into different zones at different
levels.

Each Vortex EF2280 can place 4 different signals on the bus (W, X, Y, and Z), but each Vortex EF2280 can
retrieve signals from any of the P, W, X, Y, or Z buses; thus, there are 5 sub-matrices to allow flexibility in
how the signals from other devices get mixed together and get presented to the main matrix.

how the signals from other devices get mixed together and get presented to the main matrix.
Inputs to the Submatrix come from the top and outputs are on the left. The "B" part of the inputs stands for
bus and the "M" part of the output stands for mix. Any of the rows of the matrices can be configured as a
mix-minus which allows the user to work with a simple mix-minus sum of all the other devices. Each one of
the 8 inputs represents a signal from another unit that is maintained in its discrete form until this
submatrix. Here you decide which signals to pull off of the bus, what mixes to create, and what gain or
attenuation values to assign to each one of those signals.
