Vortex Media VTX 1000 - Manual (Page 68)

Let's look at the 8 signals WB0-WB7 in the above screenshot. These signals are from 7 other Vortex
devices. In this example, the Vortex EF2280 has a device ID of 00. As a result, the WB0 column is grayed
out because the EF Bus does an automatic mix-minus so that one cannot create a loopback on the EF Bus.
The WB1-WB7 inputs can be assigned to one of the three submixes that are available for each bus channel.
Here, we are creating three mixes for three different zones. These mixes will be available as inputs to the
Matrix Mixer of the Vortex EF2280 so that these signals can be sent to the appropriate reinforcement
zones.
