The Praesideo system uses a unique loudspeaker line monitoring principle without the need to install additional cables. The loudspeaker line itself can be used to communicate with the auxiliary monitoring equipment installed at the end of the loudspeaker line. The LBB 4442 / 00 contains the main and auxiliary equipment for monitoring a single speaker line. If you want to monitor multiple speaker line branches and speakers, it is recommended to use the lbb4440 / 00 monitoring control board with LBB 4441 / 00 and LBB 4443 / 00 monitoring boards.
basic function
Each amplifier channel in the LBB 442x / x0 power amplifier unit provides internal mechanical and electrical support for the lbb4442 / 00 main monitoring board. The auxiliary monitoring board is suitable for Bosch series loudspeakers and can be installed in the last speaker on the line or in a separate housing at the end of the line. The power amplifier has built-in short-circuit grounding and short-circuit detection functions. The system can detect and report line faults within 100 seconds. The pilot tone generator used to monitor the loudspeaker is generated in the amplifier, which enhances the function of the auxiliary monitoring equipment. Users can turn off and turn on the line monitoring function through the configuration software.
