Group masters
Any of the gain, volume, trim, bass, loudness, and treble fader controls for one or more
gain blocks can be grouped with other gain blocks of the same type (in the same location
in the audio signal path but for different inputs or outputs). This creates single-fader control
of the entire group (see figure 62). Mute controls within the blocks can also be grouped
(see figure 63). Up to 32 groups can be created, each can include up to 64 group members.
NOTE: Stereo gain blocks have two, left and right, signal paths. Each path counts as a
group member, limiting you to up to 32 gain blocks total for a control group of stereo
gain controls. In figure 62, the group 3 master consists of six members (
1
through
6
).

As an example, assume that your system has several audio outputs dedicated to a single
room. You want all outputs to receive the same audio input, but there are different audio
dynamics in different parts of the room. Front row audience members need less mic audio
mixed in, and you want to insert varying degrees of delay for different audience rows.
The output 1 through output 3 analog volume controls can be grouped into a master that
controls the volume throughout the room (see figure 63).
