Communications Systems | LBC 3201/00 Line Array Indoor LoudspeakerLBC 3201/00 Line Array IndoorLoudspeaker▶ Extended listening area▶ Excellent intelligibility of speech and music▶ Uniform distribution of natural sound throughout theroom▶ Excellent directivity for use in acoustically difficult,reverberant applications▶ Suitable for larger enclosures, such as meeting hallsand places of worship▶ Extremely slim▶ Voice evacuation compliant as standard▶ EN 54‐24 and EN 60849 compliantThis loudspeaker, with its excellent directivity and highpower output, can handle medium and large (reverberant)indoor environments, especially the more acousticallychallenging ones. It is typically used in congress venues,meeting halls and places of worship. The full frequencyrange of the LBC 3201/00 makes it ideal for speech aswell as music reproduction. Its exceptionally narrowhousing (only 8 cm wide) makes it extremely unobtrusive.System OverviewA time and labor-saving mounting method has beendeveloped for the LBC 3201/00. The loudspeaker comeswith a chart, which shows the ideal installation height forthe area that the loudspeaker has to cover. Once theappropriate height has been determined for a given area,the loudspeaker is mounted at an angle marked on themounting bracket. This procedure is much simpler andmore accurate than traditional trial and error installationmethods. The LBC 3201/00 can be mounted on a wall ordirectly onto a floor stand LBC 1259/01 with an M10threaded bolt without additional accessories.Dimensions in mm of included mounting bracket (withmarked angle)www.boschsecurity.com

The specially developed high quality drivers enablereproduction of remarkably clear, natural sound, whichgives excellent intelligibility of both speech and music.The difference between a conventional columnloudspeaker and this line array is noticeable in severalways. There is uniform sound distribution throughout thewhole listening area: not too loud at the front, not to quietat the back. All relevant frequencies are presenteverywhere in the listening area. Greater coverage isachieved, so more people can be reached with speechand music with a higher intelligibility level. All theseimportant features give the experience of a very naturalsound quality in the whole listening area.Dimensions in mm*patent pending

LBC 3201/00 Line Array Indoor Loudspeaker | 3Easy installationThe advanced filtering generates larger vertical openingangles for high frequencies, so there is less narrow'beaming' of higher tones in the vertical plane. As anexample, at 4 kHz the vertical opening angle is still 22°.Having more constant vertical opening angles makesinstallation easier, as the positioning of the loudspeakersis less critical because they cover a wider area. Anextremely wide horizontal opening angle of 132° at 4 kHzmeans that a single loudspeaker can provide naturalsound reproduction over an extensive listening area.Suppressed Side LobesAll conventional column loudspeakers produce a mainlobe of sound, which is directed at listeners, as well as anumber of unwanted side lobes. The LBC 3201/00 hashighly suppressed side lobes in the vertical plane,typically at least 10 dB suppression of the 250 Hz octaveband at 90°, resulting in a much clearer, less 'colored'sound, even when close to the loudspeakers. This givesthe line array superb speech intelligibility.Sound ReproductionThe positioning and very high quality of the 2-inch driverscontribute significantly towards making the LBC 3201/00a very efficient line array. With a sound pressure level of110 dB at 1 m, and at 60 W, loud and clear soundreproduction is possible even at considerable distancesfrom the loudspeaker.The high-quality loudspeaker drivers used in theLBC 3201/00 give excellent, natural sound reproductionof frequencies ranging from 190 Hz to 18 kHz. Togetherwith the constant directivity, this ensures that allimportant frequencies are heard in the listening area.Emergency CompliantThe loudspeaker has a ceramic terminal block, a thermalfuse, and heat-resistant, high-temperature wiring. Theseensure that, in the event of a fire, damage to theloudspeaker does not result in failure of the circuit towhich it is connected. Thus, system integrity ismaintained, and loudspeakers within the sameloudspeaker zone in other areas can still be used toinform people of the situation.The three-way ceramic terminal block with screwconnections is suitable for loop-through wiring, and islocated in a compartment at the base of the loudspeakercolumn. There is also a switch, which allows the selectionof nominal full power (60 W), half power (30 W) orquarter power (15 W). The compartment has knockoutslots for accommodating cables.Certifications and ApprovalsAll Bosch loudspeakers are designed to withstandoperation at their rated power for 100 hours inaccordance with IEC 268-5 Power Handling Capacity(PHC) standards. These loudspeakers also comply withthe Simulated Acoustical Feedback Exposure (SAFE) test,which demonstrates that they can withstand acousticalfeedback at full power for short durations. This ensuresextra reliability under extreme conditions, leading tohigher customer satisfaction, longer operating life, andmuch less chance of failure or performance deterioration.RegionCertificationEurope CE Declaration of ConformityPolandSafetyCNBOPDeclaration of conformity EN50102(IK07)acc. to EN 60065 and CEEmergency acc. to EN 54‐24 / EN 60849Water and dust protection acc. to IEC 60529, IP 32Impact acc. to EN 50102, IK 07Installation/Configuration Notes~ØCircuit diagramFrequency responsewww.boschsecurity.com
