Communications Systems | LBC 3011/x1 Panel Loudspeakers
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 quarter-power radiation (in 3 dB steps) by
connecting the 100 V line to the appropriate primary taps
on the matching transformer via a 3-pole screw connector.
The off-white (RAL 9010) panels are injection-molded
from self-extinguishing, high-impact ABS material
(according to UL 94V0). They are finished with an
attractive perforated metal grill.
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 a ceramic
terminal block, thermal fuse, and heat-resistant, high-
temperature wiring.
