The MX392BEO from Shure is a Microflex wired boundary microphone that is equipped with a programmable, silent membrane switch, logic inputs and outputs, and green LED indicators. It can be used in boardrooms, learning centers, houses of worship, and more.

The MX392BEO features a flat frequency response of 50 Hz to 17 kHz across the vocal range, and has a sleek, low-profile design for an inconspicuous appearance. There are LED logic-input and switch logic-output terminals, screw terminal connections, and an attached unterminated cable with a bottom-exit option available.

Finally, with a balanced, transformerless output for increased immunity to noise over long cable runs, and features like the LED on/off indicator, the MX392BEO is a suitable choice to capture audio for that special event.

*The TAA-compliant models are made-to-order with a typical delivery time of 2 to 4 weeks. The additional cost of producing separate model variations is reflected in higher pricing compared to standard SKUs.
