If a performer needs a different headphone balance from the one you are hearing through the speakers, you can use Mix A or Mix B, within iD Control. Each Independent Mix can have its own channel levels alongside the Main Mix.
To make a separate performer mix, expand Mix A or Mix B in the Mixer and adjust the channel faders and pan settings for that mix.
Then open Headphone Settings and select the same mix as the HP1 source.
Changes to this cue balance leave the Main Mix unchanged. For example, if a singer needs more vocal in the headphones than you need through the speakers, raise the vocal level in Mix A and select Mix A for HP1. Both headphone sockets share that same HP1 mix.
Only one mix can be expanded at a time. Main Mix is expanded by default, while Mix A and Mix B are collapsed. Expand a mix to view its Volume control, Solo, output meters and Histograph. When collapsed, only the mix name and Solo control are shown.
Use Solo on Mix A or Mix B to audition the performer mix through the Monitor Output.
The first time you open an Independent Mix, its channel controls start from their default state. Any changes you make are then saved automatically for recall.
