Bosch LB2?UCxx?x Manuals

Communications Systems | LB2‑UCxx‑x Premium‑sound Cabinet Loudspeaker Range The LB2‑UCxx‑x Premium‑sound cabinet loudspeakers are intended for clear reproduction of speech, foreground and background music to be used in general indoor and outdoor applications. The Premium‑sound cabinet loudspeaker range consists of a 15 W and 30 W model, available in a light or dark color. The loudspeakers have selectable 8 ohm, 70 V and 100 V inputs. Typical applications are: theme bars, music restaurants, theme parks, retail outlets, audio visual, boardrooms and offices, exhibition areas, showrooms, fitness centre’s and presentation environments. Certifications and Approvals All Bosch loudspeakers are designed to withstand operating at their rated power for 100 hours in accordance with IEC 268‑5 Power Handling Capacity (PHC) standards. Bosch has also developed the Simulated Acoustical Feedback Exposure (SAFE) test to demonstrate that the speakers can withstand two times their rated power for short durations. This ensures extra reliability under extreme conditions, leading to greater customer satisfaction, longer operating life, and much less chance of failure or performance deterioration. Safety acc. to EN 60065 Water protection acc. to EN 60529 IP x4 Self extinguishing acc. to UL94 V 0 Installation/Configuration Notes The cabinets include a built‑in transformer that offers a selection of nominal full power, half power, quarter power or eight power radiation (i.e. in 3 dB steps) for 70 V, 100 V or 8 Ohm bypass. Selection is done by a convenient switch on the rear enclosure. A two meter long twin‑core loudspeaker cable (in matching color with the cabinet) is connected to the loudspeaker. The core ends are stripped ready for use. The cabinets can be mounted horizontally to allow the loudspeaker to be directed up or down, or vertically to allow left and right rotation by means of a steel U-shaped wall bracket (standard supplied). The rotatable logo can be easily adjusted to match the mounting orientation.
