The BLU-6 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. This controllers connects to the control ports on the rear of any BLU-16, BLU-32 or BLU-80 device. The BLU-6 offers an eight-way switch, but instead of a rotary volume control has a pair of spin or up/down buttons, enabling the same level parameter to be mapped onto other controllers preventing a jump in audio level when the control is adjusted. The switches on the unit have blank areas for marking the switch functions, either directly onto the white area, or on self-adhesive labels.
