The following is a checklist for building a system with multiple Vortexes:
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 Vortex to make a simpler submatrix.
Remember that Outputs 1-8 can also be used as outputs of the matrix. The bussing
can get very complicated very quickly if you choose to spread your outputs over sev-
eral units.
To link multiple Vortex devices together, use the submatrix on the EF Bus.
The EF Bus is a high speed, low delay digital bus that includes the W, X, Y, and Z
audio busses as well as the echo canceller reference and remote control information
(for other Vortexes) and can link up to 8 Vortex devices. All busses include NOM
information and can be used for sharing microphone inputs, or for sharing mono or
stereo program information.

output mixes (W, X, Y, and Z) and place them on the bus. Each device also can create
three input mixes each from the W, X, Y, and Z busses of the other devices (for a total
of 12 mixes). The mixes can have crosspoint gains on the signals from the other
devices. See Figure 1 below. All 12 mixes become inputs to the main matrix and can
