AM-1B

Real-time Steering Array Microphone

Discontinued

AM-1B

The AM-1B is a high sound quality microphone system that features automatic adjustment capability in a slim configuration. Composed of an array microphone connected to a separate control unit, it is ideal for installations and use on lecterns. The array microphone unit's eight internal microphones detect and track the location of the sound source, picking up audio clearly and without interruption, allowing speakers to conduct presentations more naturally without worrying about the location of the microphone. In addition, setup of operation can be performed using a PC browser. The control unit can be mounted in an EIA Standard rack with the use of optional rack-mounting brackets. (1-unit size)

Built-in voice detection sensor captures voice from up to 3 m and to tracking range angles up to 180°
Level compensation for reduced volume variations
Narrow (50°) directivity assuring minimal acoustic feedback
Innovative pad-like form permitting unobtrusive placement
Removal of barrier between speaker and audience
Freedom to adopt a comfortable speaking posture
Ability to move and gesture naturally
Adjustment by PC is also possible
Tracking distance/range, sensitivity/speed, Mute on/off
