To create a zoned reinforcement system with the reinforcement levels shown in the table, the matrix
crosspoints for the zones must be adjusted to match the designed reinforcement matrix. The first step is to
create the zone groups and then map the zone groups to the amplifier outputs with the desired crosspoints
and sound reinforcement version of the input processing.
To create the different zones, select the Edit Groups... button and follow the instructions in the section
Creating Virtual Channel Groups
of microphones that include the microphones shown in the drawing of the room. Once the zones have been
created into virtual channel groups, the groups may be collapsed so that the matrix operates at the group
level - hiding the detail of the underlying microphones as shown in the following figure.
In this example Zone 1 includes the microphones shown in the following table.
