BM-110

BM-110 - Wired Boundary Microphone

The BM-110 is a capacitive interface microphone. It is designed for ceiling or desktop fixed installation. All microphones have good RF shielding effect, which can effectively isolate the RF interference of various wireless communication devices (such as mobile phones).
