System Sound reception Unicont NS-201

External signals received by the receiving unit , enter the processing module , digitized and relayed through the built-in ( and external , if available) loudspeaker. Processing module analyzes the received audio signal for a given algorithm and illuminates the display sector , indicating the direction to the signal source . Sector width , indicating the direction is determined by calculation and depends on the quality of the received signal microphones . system

highlights the sector for 5 seconds before and after until a signal (sound pressure at the microphone ) subsides below the threshold of sensitivity of the microphone. The central module NS-201CU is an electronic module ( with microcontroller ) , equipped with built- in speaker , LED display and buttons to perform basic system configuration ( dimming , volume, sensitivity of the receiving unit , etc.). The receiving unit of NS-201M is a set of electrodynamic microphones grouped into a single structure from water intended for mounting on the open deck .
