The MXL FR-401M is a professional, supercardioid condenser boundary microphone designed for high-quality audio capture in conference rooms, boardrooms, courtrooms, and teleconferencing applications where a discreet, low-profile presence is essential. Utilizing boundary layer (or pressure zone) technology, the microphone is engineered to be placed directly on a flat surface—such as a table, podium, or wall—where it leverages the acoustical characteristics of that surface to achieve a wider, more uniform frequency response and increased sensitivity. The supercardioid polar pattern provides focused, directional pickup, effectively capturing sound from participants seated around the table while offering superior rejection of ambient noise, room reverberation, and sound sources originating from the sides and rear, such as HVAC systems or projector fans.

Housed in a compact, low-profile metal casing, the FR-401M is designed to be unobtrusive, often blending seamlessly into the meeting environment. Its flat, disk-like shape allows it to lay flush on a surface or be discreetly mounted. The microphone features a built-in, low-noise preamplifier that requires standard phantom power (48V) from a connected mixer, interface, or conferencing system to operate. This active design ensures a strong, clean signal that can be transmitted over long cable runs without significant noise or signal loss. The included gooseneck adapter provides additional flexibility, allowing the microphone to be angled slightly for optimal positioning, which can be particularly useful when mounting on a wall or when the primary talkers are in a fixed location.

The utility of this microphone lies in its combination of excellent audio quality, effective noise rejection, and visual discretion. It solves the common challenge of capturing clear, intelligible speech from multiple participants in a reverberant room without the visual distraction and potential feedback issues associated with multiple stand-mounted microphones. By placing it at the center of a conference table, it can effectively pick up voices from all directions within its pickup pattern, making it an ideal solution for teleconferencing, video conferencing, and recording meetings where natural, hands-free communication is critical. The MXL FR-401M provides a professional, reliable audio solution that supports clear communication and collaboration in modern business and institutional settings.
