Group masters

Any of the gain blocks’ gain, volume, and trim fader controls 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) for single-fader control of the entire group (figure 5-9). Mute controls within the blocks can also be grouped (figure 5-10). Up to 32 groups can be created, each can include up to 16 group members.

NStereo gain blocks have two, left and right, signal paths; each path counts as a group member, limiting you to up to eight gain blocks total for a control group of stereo gain controls. In figure 5-9, the group 2 master consists of six members

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 rows of the audience. The outputs 1 through 3 volume controls can be grouped into a master (figure 5-9) that controls the volume throughout the room.

Each individual volume control in the group can be set for that output, but when you move the group fader, all three output controls’ faders move in tandem, retaining their relative levels.
