Board BRS 23 External audio signal reception system

The Board BRS 23 system provides reception and processing of audio signals coming from different directions and their transmission to the wheelhouse with information about the direction to the sound source. It retransmits the received audio signal, while simultaneously displaying the direction to its source relative to the bow of the vessel. The signals received by the receiver are processed, digitized and transmitted through the built-in and external loudspeakers. The processing module processes the signal according to a given algorithm, displaying the direction to the source on the indicator in the form of an illuminated sector.
