Finished wall-panel level control in EU single-gang enclosure format for LUCIA installation amplifiers. Complete assembly with glossy white face plate, white knob, and a protected label area behind a plastic screen so zone labelling stays legible and tamper-resistant. Euroblock receptacle and cable connector included; wires into the GPI port on any LUCIA model and can be configured for single-channel or ganged attenuation. Designed for retail, hospitality, and meeting-room installs where a discreet, ready-to-mount control is preferred over a DIY assembly.
