Thanks to its compact design and superior sound reproduction, the Shure Microflex MX393/O boundary hemisphere is the ideal solution for any conference room. The integrated preamplifier, programmable diaphragm switches, interchangeable capsules, logical inputs and outputs, and LED indicators equip this microphone for a wide variety of applications.
Half-cardioid (C), semi-supercardioid (S) and hemispherical (O) capsules provide solutions for a wide variety of sound requirements. DIP switch programmable buttons can be used either as talk button, mute button or on/off button.
With the help of the enclosed paint covers, the MX393 can be customized in color as needed.
