S-Track Microphone Array System with AEC

Description

NAJA A301 array microphones adopt beamforming algorithm to locate sound sources for accurate acquisition, long distance pickup system, also avoiding invalid noise entering the audio system.

·The array microphone unit is composed of six silicon microphones;

·Built in digital signal processor can perform unique echo cancellation, noise cancellation and beamforming Shape and reverberation elimination algorithm;

·The pickup distance can be up to 1-5m;

·The original non-stationary noise elimination can effectively suppress the environmental noise such as the sound of turning books and footsteps;

·Support ceiling installation and desktop installation;

·With standard network interface, support system upgrade;
