This loudspeaker, with its excellent directivity and high
power output, can handle large (reverberant) indoor
environments like airport departure lounges, train stations
and congress venues. It is also suitable for outdoor use,
for instance in railway stations or sports stadiums. Its full
frequency range makes it ideal for speech as well as music
reproduction.
System Overview
A time- and labor-saving mounting method has been
developed for the LBC 3210/00. A chart is supplied with
the loudspeaker, which shows the ideal installation height
for the area the loudspeaker has to cover. Once the
appropriate height has been determined for a given area,
the loudspeaker is mounted at an angle marked on the
mounting bracket. This simple procedure is very much
simpler and more accurate than traditional trial and error
installation methods. The LBC 3210/00 can be mounted
on a wall or directly onto a floor stand LBC 1259/01 with
an M10 threaded bolt without additional accessories.
Mounting bracket (included) with marked angle.

Functions
Range of Application
The LBC 3210/00 is part of the XLA 3200 (eXtended
Listening Area) range of line array loudspeakers.
Advanced filtering and positioning of the loudspeaker
drivers* has resulted in greatly improved audio directivity.
Each speaker driver produces a dedicated frequency
range. The difference between a conventional column
loudspeaker and this line array is noticeable in several
ways. There is uniform sound distribution throughout the
whole listening area: not too loud at the front, not too
quiet at the back. All relevant frequencies are present
everywhere in the listening area. Greater coverage is
achieved, so more people can be reached with speech
and music with a higher intelligibility level. All these
important features will give the experience of a very
natural sound quality in the whole listening area.

Easy Installation
The advanced filtering generates larger vertical opening
angles for high frequencies, so there is less narrow
'beaming' of higher tones. Compared to conventional
column loudspeakers, this line array has a more constant
opening angle for all relevant frequencies. As an example,
at 4 kHz the vertical opening angle is still 18°. Having
more constant vertical opening angles makes installation
easier, as the positioning of the loudspeakers is less
critical because they cover a wider area. An excellent
horizontal opening angle of 90° 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 3210/00 has
highly suppressed side lobes in the vertical plane,
typically at least 10 dB from the 250 Hz octave band at
90°, resulting in a much clearer, less 'colored' sound, even
when close to the loudspeakers. This gives the line array
loudspeaker superb intelligibility of both speech and
music.
Sound Reproduction
The positioning and very high quality of the 4-inch drivers
contribute significantly in making the LBC 3210/00 a very
efficient line array. With a sound pressure level of 115 dB
at 1 m at 60 W, loud and clear sound reproduction is
possible even at considerable distances from the
loudspeaker.
The high-quality loudspeaker drivers used in the
LBC 3210/00 give excellent, natural sound reproduction
of frequencies ranging from 190 Hz to 20 kHz. Together
with the constant directivity this ensures that all
important frequencies are heard in the listening area.
Emergency Compliant
The loudspeakers ceramic terminal block, thermal fuse
and heat-resistant, high-temperature wiring, ensure that,
in the event of a fire, damage to the loudspeaker does not
result in failure of the circuit to which it is connected. In
this way, system integrity is maintained, ensuring
loudspeakers in other areas within the same loudspeaker
zone can still be used to inform people of the situation.
The line arrays have provision for mounting the optional
line/loudspeaker supervision board.
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 column.
There is also a switch which allows the selection of
nominal full power (60 W), half power (30 W) or quarter
power (15 W). The compartment has knock-out slots for
accommodating cables.
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.
