Because the three channels are the same and custom panelization often costs extra, the current idea is to have some separate schematics and layouts for:

Channel strip: pre-amp + gain stage, headphone mix and VU meter (including their potentiometers and buttons)
Headphone I/O: Microphone and headphone jacks, headphone amp and gain potentiometer
Line I/O: XLR jacks and signal conversion for stage input and line output + microphone summing
Power supply

For a full interpreter unit, 3 channel strip and headphone modules are needed, as well as one line I/O and power supply module.

To accomodate the actual UI layout draft, a full re-design of the PCB is needed. This should also incorporate the mission on-air button (with a separate LED now), but otherwise the schematic will stay more or less the same.
