15 W acoustic column in 100 V line, with 15, 7.5, 3.5, 2.5, 1.2 and 0.75 W sockets, EN 54-24 certified. It is a device with a small enclosure, very narrow (92 x 210 x 70 mm) and with a swivel joint, all made of ABS Ronfalin, for wall or ceiling anchoring. In addition to the usual uses of acoustic columns, such as places of worship, meeting rooms and lobbies of hotels or transport stations, its EN 54-24 certificate allows the column to be used in any public address and voice alarm systems that must comply the EN 54 standard. Its small size also allows it to be mounted on luminaires (station platforms, fashion stores, lobbies ...).
