Lab.gruppen has moved into new territory once again with the launch of a new install-dedicated amplifier series – LUCIA.

Addressing the specific needs of the AV contractor market for high quality, localised audio systems, the two-channel LUCIA (Localised Utility Compact Intelligent Amplification) is a compact and versatile Energy Star-compliant Class D amplifier platform, packed with innovative features and high sonic performance. Designed with speed of install and easy configuration in mind, LUCIA combines cutting edge low-impedance amplifier electronics with advanced DSP in the smallest amplifier the company has ever produced.

For small-scale AV applications where high quality audio is required, without the complication and additional cost of a distributed system with centralised rack-mounted amplification, matrixing and processing, LUCIA offers systems designers a more logical and cost-efficient solution, one that is ideally suited for corporate boardrooms, classrooms and small lecture theatres, museum multi-media areas and retail units.

The range comprises four models across two power configurations – 2 x 60 W and 2 x 120 W – each available with either four-in, four-out matrix-mixer and configurable DSP features (LUCIA 120/2M, LUCIA 240/2M) or in a basic two-in two-out configuration (LUCIA 120/2 and LUCIA 240/2). While all models are equipped with DSP pre-configured ‘out of the box’, the Matrix variants also facilitate easy setup via USB connection (with Windows and Mac LUCIA configuration software) to unlock the full potential of the processing and mix-matrix to meet specific system requirements.

Featuring classic Lab.gruppen limiters and mastering-quality EQ and processing algorithms evolved from TC Electronic’s System 6000, LUCIA is a true synthesis of TC Group’s technologies. Among other advanced DSP features, the Enhanced Bass Profile delivers improved LF performance from standard full-range in-ceiling or surface mount loudspeakers, to the extent that a separate subwoofer may not be required.

The amplifiers also benefit from an Auto Load Sense feature, with the device automatically measuring the impedance of a connected loudspeaker load and adjusting itself accordingly to deliver full power at all impedances (2 – 8 ohm). All LUCIA models also come with intelligent fan control for silent operation at low volumes, and low noise even at high output when the fan is operational.

Klas Dalbjorn, product research manager for install products, said: “LUCIA breaks new ground for Lab.gruppen, at the same time drawing on our knowledge and expertise in powerful, energy efficient amplification. Like E Series, LUCIA is Energy Star compliant, and is built upon proven Class D technology. The ease of install, ease of use and relatively low through-life cost make this a very compelling choice in today’s marketplace.”

Conceivably, each LUCIA model could drive up to 16 speakers on a localised low-impedance system (eight per channel – if the loudspeakers were 16 ohms). Tailor made presets will also be available for Tannoy’s commercial loudspeaker ranges, along with additional hardware accessories to provide mounting flexibility.
