The Bosch panel loudspeakers and matching mounting boxes
are ideal for built-in sound installations in shops, department
stores, schools, offices, hotels and restaurants. They are
manufactured and finished to the same exacting standards as
all Bosch public address systems and components,
guaranteeing high-quality and compatibility throughout the
range.

Functions

The 9 W (max. power) panel is equipped with a woofer and
tweeter, enabling excellent quality speech- and music
reproduction. They are available with or without an integral
volume control (LBC 3011/51 and LBC 3011/41 respectively).
Nominal output power can be preset to full, half or quarter­power radiation (i.e. in 3 dB steps) by connecting the 100 V
line to the appropriate primary taps on the matching
transformer. Connections are made via a 2-pole screw
connector.
The off-white (RAL 9010) panels are injection-moulded from
self-extinguishing, high-impact ABS material (according to
UL 94V0). They are finished with an attractive perforated
metal grille.

The panel loudspeakers flush-mount into rectangular cut­outs in cavity walls, ceilings, furniture or custom-made
cabinets. The panels have provision on the rear side for
mounting an optional line/loudspeaker supervision board.
The loudspeaker has built-in protection to ensure that, in the
event of a fire, damage to the loudspeaker does not result in
failure of the circuit to which it is connected. In this way,
system integrity is maintained, ensuring loudspeakers in other
areas can still be used to inform people of the situation. The
loudspeaker has ceramic terminal blocks, thermal fuse and
heat-resistant, high-temperature wiring.
