The Shure MX392 is a boundary microphone that builds upon the foundation of the MX391, offering a supercardioid polar pattern for applications requiring even greater directionality and feedback rejection. Designed for surface mounting on tables or integration into architectural elements, it utilizes boundary layer technology to enhance sensitivity and provide a wide, consistent pickup area from its low-profile position. The supercardioid pattern offers a tighter front pickup angle compared to a standard cardioid, with more aggressive rejection of sound arriving from the sides and rear. This makes it an excellent choice for environments with high ambient noise, challenging acoustics, or where gain-before-feedback is a primary concern, such as in large conference rooms, lecture halls, or stages.

Its discreet, low-profile housing minimizes visual intrusion, making it suitable for formal settings where aesthetics are important. The MX392 requires standard 48V phantom power for its internal condenser element and preamplifier, delivering a strong, clean signal capable of long cable runs. The semi-recessed design simplifies installation on flat surfaces and contributes to reduced mechanical noise transmission. By strategically placing one or more MX392 microphones, sound system designers can achieve clear audio pickup of targeted speaking areas while effectively minimizing the amplification of unwanted room noise, loudspeaker spill, and other off-axis distractions.

For installed sound professionals, the MX392 provides a valuable tool for optimizing speech intelligibility and system stability. Its directional characteristics allow for more precise zone coverage within a room, enabling better control over the sound field. Whether used for voice reinforcement, teleconferencing, or recording, this microphone delivers reliable, clear audio capture in a durable and unobtrusive package, addressing the specific acoustic challenges present in many fixed installation environments.
