The Lab Gruppen LUCIA 120/1-70 is a single-channel install amplifier delivering 120 W into 70 V constant-voltage speaker lines, 60 W at 100 V, or 120 W into a 16 Ω load. Constant-voltage (70/100 V line) distribution lets one amplifier drive long chains of tapped ceiling and wall speakers, the standard approach for background music and paging in retail, hospitality and corporate spaces. Part of Lab Gruppen’s decentralised LUCIA platform, the half-rack 1U chassis ships with a wall-mount bracket so power, DSP and I/O sit exactly where the zone needs them, behind a display, above a ceiling tile or inside a counter.
