The Sennheiser MEB 104 B is a professional boundary layer condenser microphone engineered for permanent, flush-mount installation in environments demanding high audio quality with a discreet visual presence. Utilizing the boundary effect principle, the microphone is designed to be installed directly onto a large, flat surface such as a conference table, lectern, or wall, where the surface acts as an acoustic extension of the diaphragm. This configuration minimizes phase cancellations and comb filtering, resulting in a remarkably natural and open sound with enhanced low-frequency response and a wide, hemispherical pickup pattern. Its half-cardioid polar pattern provides excellent coverage for capturing multiple speakers or general room ambiance with clarity, making it a premier choice for executive boardrooms, courtrooms, legislative chambers, and high-end teleconferencing systems.

This microphone incorporates a high-quality condenser capsule that delivers a smooth, extended frequency response optimized for speech intelligibility and natural vocal reproduction. It operates on standard 48-volt phantom power supplied through the connected balanced audio cable, which also carries the clean, low-noise signal to the mixer or digital signal processor. The unit's housing is a low-profile, rectangular enclosure finished in a matte black to blend seamlessly into professional interiors, and it includes a threaded insert for secure and stable mounting. A subtle LED indicator provides visual feedback for operating status, which can be integrated with room control systems for mute functions, adding user control without compromising the minimalist aesthetic.

Installation flexibility is a core feature, as the MEB 104 B can be surface-mounted, semi-recessed, or fully recessed into a custom cutout, allowing system integrators to achieve the desired visual profile for any space. The included mounting template and hardware facilitate a professional and clean installation. The microphone's performance is characterized by very low self-noise and high maximum sound pressure level handling, ensuring pristine audio capture from quiet conversations to forceful presentations. As a dedicated installed solution, it provides a reliable, set-and-forget audio source that delivers superior, natural-sounding pickup for voice reinforcement, recording, and conferencing, enhancing communication without any visible microphone presence to distract participants.
