Overview

LUCIA 120/1-70

LUCIA 120/1-70 Incorporates Ease of Install with 120 W of Decentralised Power in a Compact Energy Star Compliant Amplifier.

Great Sound, Flexibility and Ease of Use

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 consistently outstanding performance, LUCIA offers a logical, cost-efficient and scalable solution that often eliminates the complications and added expense of a centralized equipment room. 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 LUCIA the best-sounding and most reliable compact amplifier in its category.

Fits in Anywhere

LUCIA 120/1-70 has been designed and engineered for quick installation and easy setup. The supplied wall-mount bracket enables discreet on-wall location (such as behind video displays), but the ultra-compact form factor also allows easy placement virtually anyplace – whether next to a projector or integrated into a reception counter, podium & lectern or bar area. All input and output connections are on Euroblock screw terminals (with parallel unbalanced RCA connectors), and level setting is available on front-panel potentiometers. Advanced circuitry protects the amplifier and connected loudspeakers from potential damage caused by clipping, thermal overload, or extreme low line voltage.

Integrated Mix-Matrix and DSP Front End

The LUCIA 120/1-70 incorporates a digital front end with a 2 x 1 Mix Matrix and comprehensive DSP features, including proprietary Automatic Dynamic Loudness Contouring (ADLCTM) and a full selection of EQ filters both before and after the matrix – features that eliminate the need for external mixers and processors in many applications, saving time and money. A software wizard facilitates fast setup, while the advanced editor allows offline configuration of common presets that can be quickly downloaded to multiple units via USB.
