The LB2-UC30-D1 Premium‑sound cabinet loudspeaker IS intended for clear reproduction of speech, foreground and background music to be used in general indoor and outdoor applications. The Premium‑sound cabinet loudspeaker consists of a 30 W model, available in a dark color. The loudspeaker has selectable 8 ohm, 70 V and 100 V inputs. The ABS cabinets are fitted with aluminum front‑grilles and standard supplied with aluminum bracket. Typical applications are: theme bars, music restaurants, theme parks, retail outlets, audio visual, boardrooms and offices, exhibition areas, showrooms, fitness centers and presentation environments. Certifications and approvals Quality assurance All Bosch loudspeakers are designed to withstand operating at their rated power for 100 hours in accordance with IEC 60268-5 Power Handling Capacity (PHC) standards. Bosch has also developed the Simulated Acoustical Feedback Exposure (SAFE) test to demonstrate that they can withstand two times their rated power for short durations. This ensures improved reliability under extreme conditions, leading to higher customer satisfaction, longer operating life, and lessons the chance of failure or performance deterioration.
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 mounting brackets are fitted with anti‑theft torx screws, covered with plastic covers in matching color of the cabinets. 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 Ushaped wall bracket (standard supplied). The rotatable logo can be easily adjusted to match the mounting orientation.
