Crown MB3 Boundary MicrophoneThe Crown MB 3 is a miniature boundary microphone for multi miking applications such as teleconferencing, distance learning, boardrooms, courtrooms, and security applications. This low profile, circular mic permanently installs into a hole drilled in a table, lectern, or ceiling. Thanks to its supercardioid pickup pattern, the MB 3 greatly reduces ambient noise and pickup of room reverberation. The result is a clearer, more intelligible sound. On the bottom of the mic is a tubular power module with a 3 pin XLR type output connector. It is powered by 12 48V phantom power, and has a low impedance balanced mic level output. Specifications Type Phase Coherent Cardioid. Element Electret condenser. Frequency response typical 50 Hz to 15,000 Hz at 30 degrees incidence to surface. Polar pattern Half supercardioid supercardioid in the hemisphere above the primary boundary. Impedance 150 ohms, balanced recommended load impedance 1000 ohms or greater. Open circuit sensitivity typical 22 mVPa 33 dB re 1 voltPa. Power sensitivity 30.5 dB re 1 mWPa. EIA rating 125 dBm. Equivalent noise level self noise 22 dB SPL typical 0 dB0.0002 dynecm2, A weighted. SN rati 72 dB at 94 dB SPL. Maximum SPL 120 dB SPL at 3 THD. Polarity Positive inward pressure on the diaphragm produces positive voltage on pin 2 with respect to pin 3. Operating voltage Phantom power, 12 48 volts DC on pins 2 and 3 with respect to pin 1 of output connector. Current drain 4 mA nominal. Connector 3 pin pro audio, XLR M type.
