  • The Crown® MB-4 is a miniature boundary microphone for multi-miking applications such as teleconferencing, distance learning, boardrooms, courtrooms, and TV or theatrical applications. Double-sided sticky tape is provided for attaching the unit under shelves, on walls, etc. Thanks to its supercardioid pickup pattern, the MB-4 greatly reduces ambient noise and pickup of room reverberation. The result is a clearer sound.

    Features:

    • Ideal for teleconferencing, distance learning, boardrooms and courtrooms
    • Has a 15-foot attached cable leading to an XLR-type output connector with built-in mic electronics
    • Half-supercardioid polar pattern reduces feedback, room acoustics and background noise
    • Clear, natural sound
    • Small and inconspicuous
  • 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 mV/Pa* (–33 dB re 1 volt/Pa)
    Power sensitivity –30.5 dB re 1 mW/Pa.* EIA rating –125 dBm
    Equivalent noise level (self-noise) 22 dB SPL typical (0 dB=0.0002 dyne/cm2), A-weighted
    S/N ratio 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
