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 and MX393 models include an internal preamplifier.

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.


  • The MX393 feature programmable logic input and output. Additionally they provide following benefits:

  • Flat frequency response across the vocal range for uncolored sound

  • Interchangeable cartridges that provide a choice of polar pattern for each application

  • Sleek, low-profile design for surface mounting

  • Programmable mute button

  • LED indicator

  • Logic input/output for remote control or use with automatic mixers

  • RF filtering
