Description The BM-111 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). Output impedance: <200 ohms Signal-to-noise ratio: 68dB, 1KHz at 1Pa Frequency Response: 80-18,000 Hz Specifications Item Model Number BM-111 Radio Head Backplane polarized electrostatic capacitive type Pointing Characteristics Hemispherical (unidirectional) Frequency Response 80-18,000 Hz Turn-On Sensitivity 18 mV/Pa =-34.4 dBV Output Impedance <200 ohms Maximum Withstand Sound Pressure 106 dB [SPL@1%THD] Signal-To-Noise Ratio 68dB, 1KHz at 1Pa Noise Voltage 6.0 μV [A] Phantom Power DC 12-52V Current Consumption 4mA (typ.)
