The Premim sond cabinet lodspeaker range consists of a W and 3 W model, available in a light or dark color. The lodspeakers have selectable 8 ohm, 7 V and V inpts. The ABS cabinets are fitted with alminm front grilles and standard spplied with alminm bracket. Typical applications are: theme bars, msic restarants, theme parks, retail otlets, adio visal, boardrooms and offices, exhibition areas, showrooms, fitness centre s and presentation environments. ertifications and approvals Qality assrance All Bosch lodspeakers are designed to withstand operating at their rated power for hors in accordance with IE 268 Power Handling apacity (PH) 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, leading to higher cstomer satisfaction, longer operating life, and lessons the chance of failre or performance deterioration.

2 2 Range Selection is done by a convenient switch on the rear enclosre. A two meter long twin core lodspeaker cable (in matching color with the cabinet) is connected to the lodspeaker. The core ends are stripped ready for se. The monting brackets are fitted with anti theft torx screws, covered with plastic covers in matching color of the cabinets. The cabinets can be monted horizontally to allow the lodspeaker to be directed p or down, or vertically to allow left and right rotation by means of a steel U- shaped wall bracket (standard spplied). The rotatable logo can be easily adjsted to match the monting orientation. LB2 U-D/L 2 [8.] 36 [.4] Front and top view mm (in).
