Easy installation
The advanced filtering generates larger vertical
opening angles for high frequencies, so there is less
narrow 'beaming' of higher tones in the vertical plane.
As an example, at 4 kHz the vertical opening angle is
still 22°. 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 extremely wide horizontal opening
angle of 132° 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, as well as
a number of unwanted side lobes. The LBC 3201/00
has highly suppressed side lobes in the vertical plane,
typically at least 10 dB suppression of 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 superb speech intelligibility.

Sound Reproduction
The positioning and very high quality of the 2-inch
drivers contribute significantly towards making the
LBC 3201/00 a very efficient line array. With a sound
pressure level of 110 dB at 1 m, and 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 3201/00 give excellent, natural sound
reproduction of frequencies ranging from 190 Hz to
18 kHz. Together with the constant directivity, this
ensures that all important frequencies are heard in the
listening area.

Emergency Compliant
The loudspeaker has a ceramic terminal block, a
thermal fuse, and heat-resistant, high-temperature
wiring. These 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. Thus, system
integrity is maintained, and loudspeakers within the
same loudspeaker zone in other areas can still be used
to inform people of the situation.

The three-way ceramic terminal block with screw
connections is suitable for loop-through wiring, and 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 knockout 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
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.
