CONFERENCE COMPOSER LAYOUT
Most of the default parameters of the EF2280 will satisfy our design. However, we will need to
change the Mic/Line Inputs, Automixer, Matrix Mixer, and Presets to satisfy our design goals.
Mic/Line Inputs
On Inputs 5-7, the AEC needs to be set to R2 as shown in Figure 25.
Figure 25. Setting the microphone inputs 5 – 7 to reference R2.
Matrix Mixer
The matrix mixer will need to be changed from the default settings in order use Outputs A and B
for the amplifier, and Outputs C and D for the VSX 8000.
