Description

Bosch high-efficiency horn loudspeakers provide excellent speech reproduction and sound distribution for a wide scope of outdoor applications. They are ideal for sports grounds, parks, exhibitions, factories and swimming pools.

The Bosch LBC3481/12 is a circular horn loudspeaker, and the LBC3491/12 is a rectangular model. Both are 10W, and are made from ABS. The LBC3492/12 is a circular, 20W horn loudspeaker with a large horn measuring 354mm in diameter. The Bosch LBC3481/12 is made from a combination of aluminum with ABS for optimum strength and low weight. The edge of the horn is covered with a PVC profile for protection against impact damage. The LBC3493/12 is a circular, 30W horn loudspeaker with a large horn measuring 400mm in diameter. It is made from a combination of aluminum with ABS for optimum strength and low weight. The edge of the horn is covered with PVC for protection against impact damage.

All four models are for direct connection to a 100V line output and are finished in light grey (RAL 7035). The horns are water and dust protected. The horn loudspeakers include a 100V transformer with taps on the primary winding to allow different power settings. Nominal full-power, half-power or quarter-power radiation (in 3 dB steps) can easily be selected by connecting the amplifier output to the appropriate tap. A 2m four-core cable is fitted to the horns. Each core is a different color, and is connected to one of the primary taps on the transformer. The horn loudspeakers are supplied complete with sturdy adjustable mounting brackets, allowing the sound beam to be accurately directed.
