LAB GRUPPEN LUCIA 60/2_US1 Compact 2 x 30W Amplifier for Installation Applications (LUCIA 60/2_US1)

LUCIA 60/2 Incorporates Ease of Install with 2 X 30 W of Decentralized 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) redefines AV system design by delivering superior audio performance and exceptional flexibility. Its design strategically places power, processing, control, and I/O precisely where needed, heralding a decentralized approach. In numerous AV setups demanding consistently outstanding performance, LUCIA emerges as the logical, cost-effective, and scalable solution. Its decentralized nature often eradicates the complexities and added expenses associated with a centralized equipment room, simplifying AV setups. LUCIA amplifiers unite a digital, firmware-driven front end with Lab Gruppen's robust, efficient output stage, establishing it as the pinnacle of compact amplifier excellence. This fusion of superior sound and unwavering reliability positions LUCIA as the finest and most dependable compact amplifier in its category, setting a new benchmark for performance and reliability.

Integrated Mix-Matrix and DSP Front End

The LUCIA 60/2 is equipped with a digital front end featuring a 2 x 2 Mix Matrix and an extensive range of DSP capabilities. Among its offerings are the exclusive Automatic Dynamic Loudness Contouring (ADLCTM) and a comprehensive set of EQ filters, positioned before and after the matrix. These capabilities render external mixers and processors unnecessary in various applications, delivering not just cost savings but also time efficiency. To streamline setup, a software wizard expedites the process, while an advanced editor enables offline configuration of popular presets. These customized configurations can be swiftly transferred to multiple units via USB, ensuring efficiency in management and tailoring an optimized audio experience.

Green Credentials

LUCIA amplifiers are Energy Star qualified, making them an ideal choice for installation in projects seeking energy-efficient certifications. The amplifiers automatically enter standby mode after a 20-minute period with no signal input, consuming less than 1 watt. Automatic power-up occurs within two seconds after an input signal is sensed.

ADLC for Great Sound, Everytime

Automatic Dynamic Loudness Contouring ensures a fuller and more comfortable listening experience – especially at low perceived levels. Based on industry-leading technology from TC Electronic, ADLC ensures that LUCIA delivers optimum reproduction of the source signal regardless of output gain (or “volume”).

Auto Load Sense

Lab Gruppen’s innovative Auto Load Sense Technology detects the impedance load on each channel and self-configures the output stage 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, connected 8 per channel).

Third Party Control

Once installed the LUCIA can be controlled and monitored either via GPIO or more extensively using the RS232 interface that is included. The protocol used is open and free for anyone to implement. The list of companies supporting it is growing.

Energy Star Qualified

By maintaining very low current draw during operating cycles even at high output levels, and reduced power consumption during non-operational cycles, our Energy Star-qualified products harness impeccable Lab Gruppen sonic performance and robust power output while meeting the rigorous efficiency requirements of current Energy Star certification standards.

Low Impedance Amplification

There are many advantages to Lo-Z audio systems compared to constant voltage ‘distributed systems’. LUCIA harnesses all of these to give you the best sounding solution in the most cost-efficient package: Better sound, improved LF performance, save cost on loudspeakers without transformers and no need for long cable runs or conduit.
