The Bosch Praesideo LBB4440/00 supervision control board. Controls up to 80 speaker and line supervision boards (LBB 4441/00 and LBB4443/00). Open circuit fault detection.


The board controls the communication between the Praesideo system and the loudspeaker or loudspeaker line supervision boards.

The LBB 4440/00 is the supervision control board, monitoring multiple supervision-slave boards (LBB 4441/00 and LBB 4443/00), which are mounted inside the loudspeakers on the line. With these boards working together, it is possible to supervise 16, 64, or up to 80 loudspeakers or loudspeaker lines on a 500- watt amplifier.

Each amplifier channel in an LBB 442x/10 Power Amplifier unit has an internal mechanical and electrical provision for an LBB 4440/00 control board. Communication between the supervision boards takes place inaudibly over the loudspeaker line, requiring no additional wiring. The audio signals on the lines do not affect communication. Monitoring can be switched on and off from the configuration software. The monitoring of the presence of supervisor boards is continuous.

Loudspeaker faults are detected and reported within 300 s, and line faults are detected and reported within 100 s.

LBB4440/00 - line and loudspeaker supervision master PCB for mounting in a Praesideo network connected power amplifier, one board is needed per channel.
