Conications Systems LBC 347x/ Horn and Driver Lodspeaker Range LBC 347x/ Horn and Driver Lodspeaker Range High efficiency drivers Excellent speech reprodction Easy assembly Water- and dst protected to IP 65 Provision for side montg of optional spervision boards Bosch high efficiency horn lodspeakers provide excellent speech reprodction and sond distribtion for a wide scope of otdoor applications. They are ideal for sports gronds, parks, exhibitions, factories and swig pools. System overview This range cldes two circlar type horns with apertre diameters of 355 (14 ) and 49 (2 ) and three driver nits of 25 W, 35 W and 5 W. The assembly of the horn with the driver (separate ordered) reslts an tegrated horn lodspeaker. In this way the assembly of horn and driver, LBC3472/ and LBC3478/ is identical to the tegrated horn lodspeaker LBC3482/. The assembly of LBC3473/ and LBC3479/ is identical to the tegrated horn lodspeaker LBC3483/. The assembly of LBC3474/ and LBC3479/ is identical to the tegrated horn lodspeaker LBC3484/. The horns LBC3478/ and LBC3479/ are made from almm and the edges of the horns are covered with a PVC profile for protection agast impact damage. The driver nits LBC3472/, LBC3473/ and LBC 3474/ have an almm ner cone and are provided with steel montg brackets. The rear cover of the driver nits is made from self extgishg ABS (Acc. to class UL 94 V ). Both horns and drivers are fished light grey (RAL 735). Notice To redce packagg volme and cost, the drivers as well as the horns are packaged 6 per box. The mimm order qantity is therefore 6 drivers and 6 horns. Drivers and horns to be ordered separately.
2 LBC 347x/ Horn and Driver Lodspeaker Range Certifications and approvals Qality assrance All Bosch lodspeakers are designed to withstand operatg at their rated power for 1 hors accordance with IEC 268-5 Power Handlg Capacity (PHC) standards. Bosch has also developed the Simlated Acostical Feedback Exposre (SAFE) test to demonstrate that they can withstand two times their rated power for short drations. This ensres improved reliability nder extreme conditions, leadg to higher cstomer satisfaction, longer operatg life, and lessons the chance of failre or performance deterioration.

A steel montg bracket is standard fitted onto the driver nit, allowg the sond beam to be accrately directed. The connection cable is fed ot throgh an ABS cable gland (PG 13.5) the rear cover of the driver nit. For loop throgh connection, the rear cover is fitted with a second hole (covered as standard spplied). The drivers have provision for montg the optional le/lodspeaker spervision board. Simple power settg The horn driver has a three way termal block with screw connection (cldg earth). Three primary taps are provided on the matchg transformer to allow selection of nomal fll power, half power or qarter power radiation (i.e. 3 db steps). 1/4 LBC3472/ circit diagram (db) 1dB 9 31.5 63 125 25 5 1 2k 4k 8k 16k Freqency (Hz) LBC3472/ with LBC3478/ freqency response 3 3-1 6 6-2 9 9 12-2 -1 12 37 1.45 LBC3472/ with LBC3478/ dimensions () 15 25 Hz 5 Hz 1 Hz 18 18 15 2 Hz 4 Hz 8 Hz LBC3472/ with LBC3478/ polar diagram (measred pk noise)
