The Lab Gruppen CA2401 is a single-channel 240 W commercial amplifier for distributed audio in bars, restaurants, retail, hotels, corporate and education spaces. It drives either low-impedance 4/8 Ω loudspeakers or high-impedance 70/100 V line systems, the standard approach for install runs where many ceiling speakers share one cable, and its direct drive design delivers constant power without an output transformer. Fanless convection cooling, active power factor correction, Energy Star certification and simple front-panel controls make it straightforward to install and operate.
