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 speechand 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.
