Shure MX392/O Microflex Omnidirectional Boundary Microphone

The Shure MX392/O is an omnidirectional boundary microphone designed specifically for installed sound systems in environments like conference rooms, courtrooms, and meeting spaces. It features an electret condenser element that delivers a flat frequency response from 50 Hz to 17 kHz, ensuring clear and natural speech pickup from all directions. This makes it ideal for capturing multiple speakers around a table without the need to reposition the microphone.

One of the key features of the MX392/O is its silent, programmable membrane switch. This switch can be set to operate in Push-to-Talk, Push-to-Mute, or Push-On/Push-Off modes, giving users flexible control over when the microphone is active. The switch also supports logic control through TTL LED input and switch output, allowing integration with remote systems or custom setups. The microphone comes with a 12-foot unterminated pigtail cable that exits from the back, enabling discreet, permanent installation with minimal visibility.

This microphone is powered by phantom power ranging from 11 to 52 volts, which is standard for professional audio equipment. Additionally, it features an interchangeable capsule system, allowing the microphone’s coverage pattern to be reconfigured if needed. This adaptability makes the MX392/O a versatile choice for various installed audio applications where clear voice pickup and unobtrusive design are important.

Whether you are outfitting a boardroom for clear conference calls, setting up a courtroom for accurate voice recording, or equipping any meeting space that requires reliable, wide-coverage audio capture, the Shure MX392/O offers a practical and professional solution.
