BM-113

Overhead Microphones (BM-113)

The BM-113 microphone is designed for ceiling installations. The BM-113 has a flexible short gooseneck, suitable for lower ceiling installations. The terminals are mounted on standard boxes and use a 1G panel. The small and flexible gooseneck can be easily positioned. The BM-113 is widely used for telephone/video conferencing, choir performance, distance learning and any application requiring high quality voice or music playback/recording. All microphones have good RF shielding effect and can effectively isolate RF interference from various wireless communication devices (such as mobile phones).
