Figure 28. The sub-matrix for Vortex EF2280:00 which will feed the main matrix to create the local outputs for Vortex 0: Zone 1 output and Zone
3. Combination signals WM1 and XM1 contain the microphones from Zone 2 and 4 that need to be sent to the Zone 1 amplifier and combination
signals WM2 and XM2 contain the mixes of microphones that need to be sent to the Zone 3 amplifier.
