MX391W/C - Overview

The Shure The MX391WC is a supercardioid miniature white condenser boundary microphone with an in-line preamp and a 12 foot (4 meter) attached cable that terminates to a 4-pin mini xlr connector. Equipped with features like programmable, silent membrane switches, logic inputs and outputs, and LED indicators, Microflex™ Boundary Microphones are the high-quality solution for a range of applications such as altars, boardrooms and distance learning centers. Every Microflex Boundary microphone features a choice of interchangeable condenser cartridges.

  • Features:

    • Flat frequency response across the vocal range for uncolored sound.
    • Interchangeable cardioid, supercardioid, and omnidirectional cartridges that provide optimal choice for each application.
    • Sleek, low-profile design for unobtrusive appearance.
    • Balanced, transformerless output for increased immunity to noise over long cable runs.
