With its low power consumption and Energy Star certification, the Lucia 120/1-70 is optimized for both exceptional performance and environmental responsibility, making it perfect for venues such as conference rooms, retail spaces, hotels, and lecture halls. This amplifier delivers 120W of reliable power while maintaining an ultra-compact form factor, making it easy to integrate into spaces with limited room for equipment.

What sets the Lucia 120/1-70 apart is its robust DSP capabilities, which provide advanced loudspeaker processing and protection for optimal performance. The amplifier includes a digital front-end with a 2 x 1 Mix Matrix, offering comprehensive signal routing and mixing capabilities. The DSP features automatic dynamic loudness contouring (ADLC), which ensures a consistent, full-range listening experience even at lower output levels. The DSP also includes high-pass filters, parametric EQ, multi-band compression, and look-ahead limiting, all of which can be configured easily through the amplifier's intuitive setup process.

The Lucia 120/1-70's versatility is enhanced by its multiple input options, including balanced XLR inputs and unbalanced RCA connectors. These allow for easy integration into existing audio systems, with a selectable sensitivity range for both input types. The amplifier also includes an advanced software wizard for quick configuration and a powerful offline editor for creating presets that can be downloaded to multiple units via USB. Additionally, the Lucia 120/1-70's speaker protection features ensure that loudspeakers are safe from damage caused by clipping, thermal overload, or extreme line voltage fluctuations.

For energy-efficient operation, the Lucia 120/1-70 is equipped with a power-saving standby mode that automatically activates after 20 minutes of inactivity, consuming less than 1 watt of power. When a signal is detected, the amplifier powers back on within two seconds, ensuring minimal power loss and reliable system performance. The amplifier's fanless design and intelligent thermal management system further enhance its energy efficiency and ensure silent operation even at high output levels.

With its flexible mounting options, the Lucia 120/1-70 can be easily installed in a wide range of environments. The supplied wall-mount bracket enables discrete placement behind video displays or other fixtures, while its compact size allows installation in tight spaces such as podiums, reception counters, or AV racks. The unit's durability and extensive protection features, including short-circuit, thermal, and undervoltage protection, ensure long-term reliability and minimal maintenance needs.

Overall, the Lab Gruppen Lucia 120/1-70 is a highly efficient, compact, and feature-rich amplifier designed to provide outstanding performance for 70V/100V audio distribution systems. With its DSP capabilities, energy-saving features, and advanced protection mechanisms, it is the perfect choice for installations requiring high-quality sound, reliable performance, and energy efficiency.
