Great Sound, Flexibility and Ease of Use

Enter Lab Gruppen's ingenious LUCIA (Localized Utility Compact Intelligent Amplification), revolutionizing AV system design by delivering unparalleled audio performance and unprecedented adaptability. This innovation strategically places power, processing, control, and I/O precisely where they're needed, eliminating the constraints of a centralized equipment room. In countless AV applications demanding consistent excellence, LUCIA emerges as the logical, cost-effective, and scalable solution. Its decentralized approach streamlines complexity, reducing unnecessary expenses while ensuring top-tier performance. LUCIA amplifiers merge a digital, firmware-controlled front end with Lab Gruppen's robust, enduring, and highly efficient output stage, elevating it as the epitome of compact amplifier excellence—delivering not just superior sound but also unmatched reliability within its category.

Fits in Anywhere

The LUCIA 120/2M embodies a design that transcends mere creation—it's a meticulous engineering marvel crafted for swift installation and effortless setup. Its wall-mount bracket discreetly positions it behind video displays, yet its ultra-compact form factor facilitates seamless placement in any environment. Whether nestled beside a projector or seamlessly integrated into reception counters, podiums, lecterns, or the vibrant atmosphere of a bar area, its versatility knows no bounds. Every connection point, meticulously designed on Euroblock screw terminals with parallel unbalanced RCA connectors, ensures seamless integration. Fine-tuning becomes an art with front-panel potentiometers for effortless level adjustments. The amplifier's advanced circuitry stands sentinel, shielding both the amplifier and connected loudspeakers from potential damage due to clipping, thermal overload, or extremely low line voltage, ensuring an unrivaled audio experience.

Integrated Mix-Matrix and DSP Front End

The LUCIA 120/2M incorporates a digital front end with a 4 x 4 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.

Green Credentials

LUCIA amplifiers proudly sport the Energy Star accreditation, positioning them as the prime choice for projects aiming for energy efficiency certifications. These amplifiers seamlessly transition into standby mode, sipping less than a single watt of power after 20 minutes of silence—a testament to their eco-conscious design without compromising responsiveness. Their agility shines through as they swiftly power up within a mere two seconds upon detecting an incoming signal. This blend of energy efficiency and rapid responsiveness ensures not just eco-friendliness but also readiness and efficiency when the audio signal calls.

Third-Party Control​

Once in place, the LUCIA stands ready for seamless control and monitoring through GPIO or, for a more comprehensive approach, the included RS232 interface. What sets it apart is the open and freely accessible protocol, inviting anyone to implement and harness its capabilities. Notably, an expanding roster of companies lends their support to this protocol, showcasing its growing adoption within the industry. This openness not only empowers users but also fosters a collaborative ecosystem where the possibilities for control and integration are virtually limitless.

Energy Star Qualified

Our Energy Star qualified products deliver exceptional Lab Gruppen sonic performance and robust power output without compromising efficiency. Through maintaining remarkably low current draw during operation, even at high output levels, and minimizing power consumption during non-operational cycles, these products excel in meeting the stringent efficiency standards of Energy Star certification. This harmony between impeccable sonic performance, formidable power output, and adherence to the demanding Energy Star efficiency benchmarks ensures a superior audio experience while minimizing energy consumption, marking a remarkable achievement in both performance and sustainability.

ADLC for Great Sound, Everytime

Automatic Dynamic Loudness Contouring ensures a fuller and comfortable listening experience – especially at low perceived levels. Based on industry leading technology from TC Electronic, ADLC ensures that LUCIA makes the best of what comes into the system regardless of output gain (or “volume”).

Auto Load Sense

Innovative Auto Load Sense technology which detects the impedance load on each channel and self-configures for optimal performance, allowing it to deliver maximum power output on all loads from 2-8 ohms. This means a single LUCIA amplifier can be used to effectively drive up to 16 loudspeakers (if 16 ohm devices, 8 per channel).

Low Impedance Amplification

LUCIA capitalizes on the numerous benefits of Lo-Z audio systems, presenting a superior sound solution in a cost-efficient package. By leveraging these advantages, it achieves unparalleled audio quality, enhanced low-frequency performance, and substantial cost savings. With Lo-Z systems, you benefit from superior sound quality, amplified low-frequency performance, and cost reductions by eliminating the need for transformers in loudspeakers. Additionally, the system eliminates the necessity for extensive cable runs or conduits, streamlining installation and further contributing to cost savings. This amalgamation of advantages makes LUCIA a standout choice, delivering exceptional audio performance while optimizing both quality and economy.
