Shure Microflex MX391 Wired Boundary, Condenser Microphone for Boardroom, E-learning - White

Designed for today’s collaborative spaces, the Shure Microflex MX391 boundary condenser microphone blends studio-grade sound with a discreet, professional presence. The white finish is ideal for modern boardrooms, classrooms, and e-learning environments where a clean, unobtrusive appearance matters as much as audio quality. The MX391 delivers a flat frequency response across the vocal range, ensuring an uncolored, natural sound that makes every speaker’s words clear and intelligible. Built for reliability in busy conference rooms and learning spaces, this boundary mic performs consistently across a variety of seating layouts and acoustic conditions. A standout feature is the interchangeable cartridge system, allowing you to choose the most appropriate pickup pattern—cardioid, supercardioid, or omnidirectional—to optimize coverage, minimize noise, and reduce echo. With a low-profile silhouette, balanced, transformerless output, and robust construction, the MX391 is a versatile solution for wired applications that demand clarity, durability, and ease of integration with existing AV systems.

• Uncolored, natural sound across the vocal range: The MX391 offers a flat frequency response designed to reproduce voice with minimal tonal coloration. This makes it ideal for meetings, lectures, and presentations where clear intelligibility is paramount, reducing fatigue during long sessions and ensuring every speaker is heard with accuracy.
• Interchangeable cardioid, supercardioid, and omnidirectional cartridges: Adapt the pickup pattern to your room. Cardioid helps reject ambient noise behind the mic, supercardioid tightens the pickup for focused speech, and omnidirectional captures sound from all directions—perfect for circular seating or rooms with dynamic movement.
• Sleek, low-profile design in a white finish: The MX391’s unobtrusive profile blends into conference tables and classrooms, minimizing visual distraction while maximizing voice pickup. The white color complements bright interiors and reflects a modern aesthetic without sacrificing performance.
• Balanced, transformerless output for immunity to noise: A transformerless design reduces the potential for hum and interference, supporting reliable performance over longer cable runs and in environments with multiple electronic devices, projectors, and displays.
• Versatile mounting and compatibility for boardrooms and e-learning: Built for wired deployments, the MX391 integrates easily with a wide range of conferencing systems, room controllers, and AV matrices. Its compact footprint and solid build make it suitable for desktop placement or discreet table mounting, ensuring dependable sound capture in busy meeting rooms and learning spaces.

How to Install Shure Microflex MX391

Installing the MX391 is straightforward and designed to minimize disruption in busy rooms. Follow these steps to achieve optimal placement and performance:

• Plan placement: Position the MX391 at the center of the table or on a command seating area where all participants have a clear line of sight to the microphone. If the room has a pronounced front row or podium, consider placing the MX391 slightly behind to capture voices from all directions while reducing direct proximity from speakers.
• Choose the capsule pattern: Select the interchangeable cartridge that best matches your room’s acoustics and seating arrangement. Use cardioid for environments with background noise on one side, supercardioid for focused speaking zones, or omnidirectional for rooms where participants surround the mic.
• Connect to the audio system: Run the cable from the MX391’s output to your mixer, preamp, or conference codec. Ensure phantom power is enabled on the host device to power the condenser capsule.
• Test and adjust: Conduct a quick test by having participants speak from various positions around the table. If the room exhibits echoes or handling noise, consider repositioning or swapping cartridges to improve pickup and reduce unwanted noise.
• Integrate with conferencing software: In your room’s AV system, route the MX391’s signal to the main audio bus and adjust levels to balance with other microphones, speakers, and multimedia sources. Label the mic input in your conferencing software for easy access during meetings.
• Maintenance and care: Wipe the housing with a soft, dry cloth to remove fingerprints. Avoid harsh cleaners. Periodically re-check the cartridge seating and cable connections to maintain a reliable signal path.
