Shure MX392/C Low Profile, Professional Boundary Condenser Microphone (Cardioid)

    The Shure MX392 Microflex™ Wired Boundary Microphone from Shure is equipped with features like programmable, silent membrane switches, logic inputs and outputs, and green LED indicators. It is a high-quality solution for a range of applications such as altars, boardrooms and distance learning centers. Includes LED logic input/switch logic output terminals, screw terminal connections, and attached unterminated cable.

    Shure MX392 Microphone 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

    All measurements taken with microphone mounted on a wooden surface 76.2 cm x 76.2 cm (30 in. x 30 in.).
