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.
