Shure Microflex MX391/C Wired Electret Condenser Microphone - Black

The Shure Microflex MX391/C is a premium boundary microphone designed for professional environments where clear, natural sound is essential. Encased in a discreet black housing, this wired electret condenser microphone blends seamlessly into boardrooms, altars, distance learning spaces, and a variety of meeting environments. Built to deliver reliable performance under demanding usage, the MX391/C combines accuracy, durability, and flexible control to meet the needs of modern collaboration spaces. With programmable, silent membrane switches, logic inputs and outputs, and LED indicators, it provides intuitive local control while integrating smoothly with room automation systems. Whether you’re equipping a high-profile conference room, a faith-based sanctuary, or a university lecture hall, the MX391/C is engineered to capture every important voice with minimal noise, feedback, or setup complexity.

• Superior boundary-mound sound with low-profile design: The MX391/C’s boundary microphone architecture positions a high-quality electret condenser capsule close to the sound source, delivering natural, gaze-friendly pickup across the room while maintaining a discreet, tabletop footprint that won’t interfere with presenters or seating. This makes it ideal for boardrooms, small auditoriums, and collaborative learning spaces where unobtrusive audio is as important as clarity.
• Programmable silent membrane switches for instant control: Equipped with silent membrane switches, the MX391/C enables quick muting, mic on/off, and other functions without audible clicking noise. This feature is particularly valuable during sensitive presentations, worship services, or executive briefings where silence is essential, yet fast action is required.
• Logic inputs and outputs for seamless integration: The MX391/C supports logic I/O capabilities that allow integration with room automation, touch panels, and external control systems. This enables centralized control of multiple microphones, presets for different room configurations, and streamlined management of audio during dynamic meetings or hybrid sessions.
• LED indicators for clear status at a glance: Built-in LED indicators provide immediate visual feedback on mute status, power, and fault conditions. In busy environments, these indicators help operators and presenters verify the mic’s state without interrupting the proceedings, ensuring consistent communication across the room.
• Versatile applications and rugged reliability: Designed for altars, boardrooms, distance learning centers, and other professional spaces, the MX391/C offers the performance, durability, and adaptability required for frequent use. Its robust construction and professional-grade components are built to stand up to daily abuse while maintaining consistent sound quality across a wide range of room sizes and acoustic environments.

How to install Shure Microflex MX391/C

Installing the MX391/C is straightforward, with a focus on placing the microphone for optimal coverage and easy integration with existing AV systems. Follow these steps to set up quickly and achieve reliable performance in most meeting or teaching spaces:

• Step 1: Choose a placement that places the microphone near the speaking area while remaining unobtrusive. Position the boundary microphone on the table surface toward the center of the room or where the primary speakers will be seated to maximize pickup and minimize edge reflections.
• Step 2: Connect the MX391/C to your audio system using the appropriate wired interface. Ensure the connection is compatible with your mixer, conferencing system, or DSP. If required by your setup, supply the necessary power through the professional audio path specified by your equipment manual.
• Step 3: Configure control features. If you plan to use the programmable silent switches, set the mute, record, or other preferred functions on the device or through your control system. Verify that logic inputs and outputs are properly mapped to the corresponding room automation or external controllers.
• Step 4: Calibrate gain and levels. Engage the mic and adjust the preamp level so that voices are clear without clipping or excessive noise. Test with multiple speakers and in typical room conditions to establish a stable, balanced sound across the audience area.
• Step 5: Verify LED indicators and status. Confirm that mute indicators, power status, and fault indicators (if any) reflect the expected states during operation. Use the built-in cues to monitor mic health and performance during live sessions.
• Step 6: Implement room integration. If your space uses a central control system or a network of devices, ensure the MX391/C communicates correctly with the rest of the equipment. Document settings for future reference and to simplify future reconfigurations when room layouts change.
