DTP CrossPoint 84 Series Matrix Switchers • Matrix Software 100
Group masters
Any of the gain, volume, trim, bass, 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) for single-fader control of the entire group
(see figure51) Mute controls within the blocks can also be grouped (see figure52). Up to
32 groups can be created, each can include up to 16 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 eight gain blocks total for a control group of stereo
gain controls. In figure51, the group 3 master consists of six members.

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 figure51).
