236 | Loudspeakers | XLA 3200 Line Array
Dimensions in mm
Mounted on optional loudspeaker stand (LBC 1259/01)
A three-way, ceramic terminal block with screw
connections suitable for loop-through wiring is located in
a compartment at the base of the loudspeaker. There is
also a switch, which allows the selection of nominal full
power (30 W), half power (15 W), or quarter power
(7.5 W). The compartment has knockout slots for cables.
Functions
Range of Application
The LBC 3200/00 is part of the XLA 3200 (eXtended
Listening Area) range of line array loudspeakers. The
positioning of the loudspeaker drivers* has resulted in
greatly improved audio directivity. The specially developed
high quality drivers enable reproduction of remarkably
clear, natural sound, giving excellent intelligibility of both
speech and music. Greater coverage is achieved, so more
people can be reached with perceptually perfect sound.
All this makes this small line array loudspeaker very
suitable for use in small to medium sized applications.

Easy Installation
The positioning of the drivers in the array generates larger
vertical opening angles for high frequencies, reducing the
narrow 'beaming' of higher tones. As an example, the
vertical opening angle is still 18° at 4 kHz. Having larger
vertical opening angles makes installation easier, as the
positioning of the loudspeakers is easier because they
cover a wider area. An extremely wide horizontal opening
angle of 130° at 4 kHz means that a single loudspeaker
can provide natural sound reproduction over an extensive
listening area.
Suppressed Side Lobes
All conventional column loudspeakers produce a main
lobe of sound, which is directed at listeners, and a
number of unwanted side lobes. The LBC 3200/00 has
highly suppressed side lobes in the vertical plane,
typically at least 8 dB of suppression from the 500 Hz
octave band at 90°. This provides a much clearer, less
colored sound, and greatly reduces the possibilities for
acoustic feedback.
Sound Reproduction
The positioning and very high quality of the 2 inch drivers
contribute significantly in making the LBC 3200/00 a very
efficient line array. With a sound pressure level of 106 dB
at 1 m, at 30 W, loud and clear sound reproduction is
possible even at a significant distance from the
loudspeaker.
The high-quality loudspeaker drivers used in the
LBC 3200/00 give excellent, natural sound reproduction
of frequencies ranging from 190 Hz to 18 kHz. This
ensures that all important frequencies for superb speech
intelligibility are heard in the listening area.
Emergency Compliant
The loudspeakers ceramic terminal block, thermal fuse
and heat-resistant, high-temperature wiring ensures that,
in the event of a fire, damage to the loudspeaker does not
result in failure of the circuit to which it is connected. This
maintains system integrity, ensuring that loudspeakers
within the same loudspeaker zone in other areas can still
be used to inform people of the situation.
