  • Page 5: General Description

    The AM Series is a Real-time Steering Array Microphone that efficiently picks up targeted sound by using a unique algorithm to detect the position of the sound source and control the microphone’s directivity. This microphone system consists of an array microphone unit and its control unit. The array microphone is available in two different versions: AM-1B (black) and AM-1W (white). 4. FeATUReS • The array microphone utilizes eight microphone elements to realize an array effect by means of its narrow 50° horizontal angle of directivity.
