Lab Gruppen – CA2402 – Amplifier 2 x 240 Watt – 4/8 Ohm – 70/100 Volt c/w Wall – Rack Mount Brackets

The Lab.Gruppen LUCIA 240/2 is a compact, 2-channel 240W amplifier for A/V installation applications. Localized Utility Compact Intelligent Amplification (LUCIA) offers advanced audio performance and flexibility to a decentralized approach in AV systems design. Power, processing, control, and I/O are conveniently placed exactly where they are needed. In many AV applications requiring consistent performance, LUCIA offers a logical, cost-efficient, and scalable solution that often eliminates the complications and added expense of a centralized equipment room.

The half-rack space enclosure provides fast and easy installation. The supplied wall-mount bracket allows for deployment in discrete locations, such as behind video displays or next to a projector or podium. The Lab.Gruppen LUCIA 240/2 includes Euroblock input and output screw terminals, a power cord, and mounting hardware.
