Featuring breakthrough audio and mechanical design innovations, the phantom-powered BM 100 offers outstanding speech intelligibility and transparent sound quality for surface-mount applications. The microphone is equipped with a rotating output connector, Noise filter, and RFI-shielding technology. It accepts interchangeable condenser elements—available for boundary microphones in cardioid, hypercardioid, and omnidirectional polar patterns. With a heavy die-cast case and silicon foam bottom pads to minimize the coupling of surface vibration to the microphone, the ES961 is equipped with self-contained electronics, eliminating the need for an external power module.
