  • SHUR-MX392C is a Surface-mount microphone; includes a programmable membrane on/off switch, logic input/ output terminals, an on/off indicator LED, screw terminal connections,and attached unterminated cable.

    Shure Microflex MX300 Series microphones are surface-mounted electret condenser microphones designed primarily for mounting on conference tables, stage floors, and lecterns. Their high sensitivity and wide frequency range make them especially suitable for picking up speech and vocals in sound reinforcement and recording applications. Interchangeable cartridges provide the installer with greater flexibility and make it possible to easily reconfigure microphone coverage as the need arises. The MX392 model include an internal pre amplifier. MX300 Series microphones take advantage of the principle that, at a barrier or boundary, the sound pressure level doubles. When placed near a sufficiently large boundary surface, the microphone has 6 dB higher sensitivity and approximately 3 dB greater direct-to-reverberant sound ratio.Features:
    • Flat frequency response across the vocal range for uncolored sound
    • Interchangeable cardioid, supercardioid, and omnidirectional cartridges that provide choices for applications
    • Sleek, low-profile design for unobtrusive appearance
    • Balanced transformerless output for increased immunity to noise over long cable runs
    • Low susceptibility to electromagnetic hum and RFI
    • Programmable on/off switch and LED on/off indicator
    • Logic input/output terminals for remote control or use with automatic mixers (MX392 model only)
  • Frequency Response50 to 17,000 Hz
