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 Rusing an iPad or PC browser. The control unit can be mounted in an EIA Standard rack with the use of optional rack-mounting brackets. (1-unit size)
