Bosch LBB4440/00

Praesidio Supervision Control Board

The board controls the communication between the Praesideo system and the loudspeaker or loudspeaker line supervision boards.
The LBB4440/04 is functionally equivalent to the LBB4440/00. It is intended for situations where multiwire loudspeaker cabling or shielded cabling must be used, prohibiting the use of the regular LBB4440/00 supervision control board. The LBB4440/04 offers faster fault reporting than the LBB4440/00 at the expense of a slightly increased risk of false faults.

Each amplifier channel in an LBB442x/10 or PRS-xPxxx Power amplifier unit has an internal mechanical and electrical provision for an LBB4440/0x 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.

• Multiple speaker and line monitoring without additional cabling
• Mounted inside the power amplifier
• Controls up to 80 speaker and line supervision boards
• Direct replacement of LBB4440/00 with faster fault reporting
• Compatible with 100 V and 70 V loudspeaker lines
