With LUCIA, Lab.gruppen brings significantly better audio performance and more flexibility to everyday AV applications, with real benefits for both the end-user and the audio contractor. LUCIA is a first for Lab.gruppen in providing an alternative solution to amplification and processing. This ‘decentralized’ approach to AV systems design puts power, processing, control and I/O exactly where it’s needed. Rather than conventional distributed (70 V / 100 V, often referred to as ‘constant voltage’) approach, where all amplifiers, processing and matrixes are located centrally in equipment room racks, often far removed from the end use (and the loudspeakers in those spaces), LUCIA packages all of that in one compact unit – designed to be installed locally, at the heart of any dedicated application.

The benefits include better sound reproduction (no transformers), greater user flexibility (giving local inputs and some zone control), and potentially avoiding the need (expense) for a separate AV equipment room, as well as being far easier to install and set-up for great results – saving time and money.

At the heart of LUCIA (Localized Utility Compact Intelligent Amplification) is its ingenious DSP and advanced limiter design – ensuring great sounding results, no matter what and providing a more dynamic listening experience, and more satisfying environment to be in. LUCIA is about simplicity. Removing the complications and compromises of traditional centralized audio systems, LUCIA brings truly exceptional sound quality, ease of use and flexibility to those everyday experiences where it matters most: restaurants and entertainment venues, retail, corporate boardrooms and classrooms.

LUCIA has been designed and engineered with quick install and very easy setup in mind. Each unit comes supplied with a wall-mount bracket allowing for discreet on-wall location (such as behind video displays) but can also be located close to wherever it needs to be in the room – such as next to projector or integrated into a reception counter, podium & lectern or bar area. All connections are via Euroblock screw terminals (also RCA phono inputs shared with channel 1 and 2), 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. The base models require no configuration whatsoever, with all DSP features fully automated (multi-band compressor, look-ahead limiter and load detection for optimized power output).


  • Restaurant/Entertainment: Multi-function/zoned restaurants and entertainment venues where high quality background and foreground music varies throughout certain hours of the day in defined areas (eg. bar/lounge in evening), and local inputs and control are important.
  • Retail: High quality music is a vital aspect of modern fashion retail, with flexible audio control and local input for in-store promos (eg. DJ). LUCIA provides the perfect tool to provide impact for these types of retail/mall applications.
  • Corporate: Modern high-end boardrooms and other corporate presentation spaces such as dedicated training rooms, multimedia, video-conferencing and meeting suites.
  • Education: Multimedia equipped learning – classrooms, presentation rooms, and performance spaces. The audio node is integrated with interactive whiteboard teaching environment.

Lab Gruppen LUCIA-240/2M Features:

  • Integrated Mix Matrix and DSP (LUCIA ’M’ modelsonly): The versatile 4 × 4 Mix Matrix and comprehensive DSP featuresincluding Automatic Dynamic Loudness Contouring (ADLC™), featured on theLUCIA240/2M and 120/2M eliminate the need for external mixers and processorsin many applications, saving time and money. A software wizard facilitatesfast setup, while the advanced editor allows offline configuration of commonpresets that can be quickly downloaded to multiple units via USB.
  • Green credentials: All LUCIA models are EnergyStar® qualified, making them an ideal choice for installation in projects seeking energy-efficient certifications. The amplifier automatically enters standby mode after 20 minutes of no signal input, consuming less than 1 watt.Automatic power-up requires less than two seconds of input signal presence.
  • What is LUCIA?: Designed with speed of install and flexibility in mind, the 2-channel LUCIA is an extremely compact and versatile Energy Star qualified Class D amplifier platform. Combining innovative low-impedance electronics with cutting-edge processing from the world of high-end broadcast audio, LUCIA delivers consistently great sound at any listening level.
  • LUCIA sits at the heart of almost any room or zone where high quality audio, ease of use and flexibility are requirements – providing industry-renowned amplification, innovative auto-configuring DSP, flexible input and routing control (M-models only) in one quiet-running device. It does all the hard work, providing better sounding results ‘out-of-the-box’, preventing audible clipping – even when subject to demanding operating conditions (eg. overdriven). LUCIA always sounds great.
