  • MX392 and MX393 Microflex® Wired Boundary Microphones from Shure are equipped with features like programmable, silent membrane switches, logic inputs and outputs, and green LED indicators. The high-quality solution for a range of applications such as altars, boardrooms and distance learning centers, Microflex Boundary microphones feature interchangeable condenser cartridges.

    The MX393 is a surface-mount mic with miniature three pin connector and12' XLR cable.

    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
    • Programmable membrane on/off switch plus LED on/off indicator
    • LED logic input and switch logic output terminals for remote control or use with automatic mixers (MX392 models only)
