LUCIA Operation Manual rev 1.0.0
5. Introduction
5.1. Welcome
Thank you for purchasing a Lab.gruppen LUCIA compact installation amplifier. We are confident it will provide
outstanding performance, reliable operation and a long service life in any type of commercial sound or general AV
application.
Lab.gruppen’s innovative LUCIA (Localized Utility Compact Intelligent Amplification) brings superior audio
performance and extraordinary flexibility to a decentralized approach in AV systems design. Power, processing,
control and I/O are conveniently placed exactly where they are needed. In many AV applications requiring
consistent, high quality audio output, LUCIA offers a logical, cost-efficient and scalable solution that eliminates the
complications and added expense of a centralized equipment room for amplification, matrixing and processing.
All LUCIA amplifiers incorporate a digital, firmware-controlled front end coupled to a robust, durable and highly
efficient Lab.gruppen output stage, all of which make it the best sounding compact amplifier in its category.
LUCIA amplifiers install quickly and easily, with the supplied wall-mount bracket enabling discreet on-wall
placement behind video displays. All connections are via Euroblock screw terminals, and level setting is
available on front-panel potentiometers. An advanced protection scheme protects the amplifier and connected
loudspeakers from potential damage caused by clipping, thermal overload, or extreme low line voltage.
