The BLU-3 wall panel is a simple controller which allows the designer to provide level control and source selection or preset recall in a simple wall-mounted panel. These controllers connect to the control ports on the rear of any BLU-16, BLU-32 or BLU-80 device.
The BLU-3 offers a rotary fader and a five-way switch. The switch could select system presets (configurations specific to times of the day for example) while the rotary control could be assigned to act as a zone volume control. The switches on both units have blank areas for marking the switch functions, either directly onto the white area, or on self-adhesive labels.
