System overview
The LBC 3481/12 is a circular horn loudspeaker, and
the LBC 3491/12 is a rectangular model. Both are
10 W, and are made from ABS.
The LBC 3492/12 is a circular, 20 W horn loudspeaker
with a large horn measuring 354 mm 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 a PVC profile for protection
against impact damage.
The LBC 3493/12 is a circular, 30 W horn loudspeaker
with a large horn measuring 400 mm 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.
Functions
All four models are for direct connection to a 100 V
line output and are finished in light grey (RAL 7035).
The horns are water and dust protected.
The horn loudspeakers include a 100 V 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 2 m 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.
