This loudspeaker, with its good directivity, can handle small
and medium indoor environments such as congress venues,
meeting rooms, showrooms and canteens. The full
frequency range of the LBC 3200/00 makes it ideal for
speech as well as music reproduction. Its exceptionally
narrow housing (only 8 cm wide) makes it extremely
unobtrusive.

System Overview

A wall bracket for mounting the line array onto walls and
pillars is included with the loudspeaker. It is fully adjustable
in two perpendicular planes for accurate positioning. For
temporary installations, the LBC 3200/00 can be mounted
on an LBC 1259/00 floor stand with an M10 threaded bolt
without additional accessories.

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.

EVAC 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.

Certifications and Approvals

All Bosch loudspeakers are designed to withstand
operation at their rated power for 100 hours in accordance
with IEC 268-5 Power Handling Capacity (PHC) standards.
These loudspeakers also comply with the Simulated
Acoustical Feedback Exposure (SAFE) test, which
demonstrates that they can withstand acoustical feedback
at full power for short durations. This ensures extra
reliability under extreme conditions, leading to higher
customer satisfaction, longer operating life, and much less
chance of failure or performance deterioration.
