The fll freqency range of the LBC 3200/00 makes it ideal for speech as well as msic reprodction. Its exceptionally narrow hosing (only 8 cm wide) makes it extremely nobtrsive. System overview A wall bracket for monting the line array onto walls and pillars is inclded with the lodspeaker. It is flly adjstable in two perpendiclar planes for accrate positioning. For temporary installations, the LBC 3200/00 can be monted on an LBC 1259/01 floor stand with an M10 threaded bolt withot additional accessories.

2 2 LBC 3200/00 Line Array Indoor Lodspeaker Detail monting bracket Monted on optional lodspeaker stand (LBC 1259/01) A three-way, ceramic terminal block with screw connections sitable for loop-throgh wiring is located in a compartment at the base of the lodspeaker. There is also a switch, which allows the selection of nominal fll power (30 W), half power (15 W), or qarter power (7.5 W). The compartment has knockot slots for cables. Fnctions Dimensions in mm Range of Application The LBC 3200/00 is part of the XLA 3200 (extended Listening Area) range of line array lodspeakers. The positioning of the lodspeaker drivers has reslted in greatly improved adio directivity. The specially developed high qality drivers enable reprodction of remarkably clear, natral sond, giving excellent intelligibility of both speech and msic. Greater coverage is achieved, so more people can be reached with perceptally perfect sond. All this makes this small line array lodspeaker very sitable for se in small to medim sized applications.

3 3 LBC 3200/00 Line Array Indoor Lodspeaker Easy Installation The positioning of the drivers in the array generates larger vertical opening angles for high freqencies, redcing 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 lodspeakers is easier becase they cover a wider area. An extremely wide horizontal opening angle of 130 at 4 khz means that a single lodspeaker can provide natral sond reprodction over an extensive listening area. Sppressed Side Lobes All conventional colmn lodspeakers prodce a main lobe of sond, which is directed at listeners, and a nmber of nwanted side lobes. The LBC 3200/00 has highly sppressed side lobes in the vertical plane, typically at least 8 db of sppression from the 500 Hz octave band at 90. This provides a mch clearer, less colored sond, and greatly redces the possibilities for acostic feedback. Sond Reprodction The positioning and very high qality of the 2 inch drivers contribte significantly in making the LBC 3200/00 a very efficient line array. With a sond pressre level of 106 db at 1 m, at 30 W, lod and clear sond reprodction is possible even at a significant distance from the lodspeaker. The high-qality lodspeaker drivers sed in the LBC 3200/00 give excellent, natral sond reprodction of freqencies ranging from 190 Hz to 18 khz. This ensres that all important freqencies for sperb speech intelligibility are heard in the listening area. Emergency Compliant The lodspeakers ceramic terminal block, thermal fse and heat-resistant, high-temperatre wiring ensres that, in the event of a fire, damage to the lodspeaker does not reslt in failre of the circit to which it is connected. This maintains system integrity, ensring that lodspeakers within the same lodspeaker zone in other areas can still be sed to inform people of the sitation. Certifications and approvals All Bosch lodspeakers are designed to withstand operation at their rated power for 100 hors in accordance with IEC Power Handling Capacity (PHC) standards. These lodspeakers also comply with the Simlated Acostical Feedback Exposre (SAFE) test, which demonstrates that they can withstand acostical feedback at fll power for short drations. This ensres extra reliability nder extreme conditions, leading to higher cstomer satisfaction, longer operating life, and mch less chance of failre or performance deterioration.
