Ideal for executive boardrooms, training spaces, classrooms, and collaborative work environments, the MX391W-A/O is engineered to disappear into your furniture while standing up to daily use. Its electret condenser element provides accurate vocal pickup and wide dynamic range, while a suite of intelligent features makes it easy to integrate, configure, and control within professional AV systems.

Whether you’re outfitting a single meeting room or a network of conference spaces, this boundary microphone offers a practical, future-ready solution for clear, intelligible voice pickup in real-world environments.

  • Slim, boundary-style design that sits flush on tables and podiums, providing unobtrusive placement without sacrificing pickup area or coverage.
  • Electret condenser element for accurate vocal reproduction, low self-noise, and a broad, natural-sounding frequency response that supports clear discussion and intelligible transcription.
  • Programmable, silent membrane switches for discreet control of essential functions such as mute, hold, or room actions—without audible clicks that can disrupt a meeting.
  • Interchangeable cartridges and modular architecture enable quick upgrades or reconfigurations to suit different room layouts, seating arrangements, or coverage needs.
  • LED indicators and integrated logic inputs/outputs facilitate straightforward integration with control systems, DSPs, and other AV equipment for synchronized room management.

Technical Details of Shure Microflex MX391W-A/O

  • Microphone type: Boundary microphone with electret condenser element, designed for table-top use and boundary pickup efficiency.
  • Finish: White — a slim, low-profile housing intended to blend with modern office interiors and match other Microflex components.
  • Connectivity: Wired interface compatible with standard conference room AV ecosystems and Shure Microflex networked configurations.
  • Key features: Programmable silent membrane switches, interchangeable cartridge capability, built-in LED indicators, and logic I/O for flexible control and integration.
  • Durability and reliability: Rugged construction designed for frequent use in professional environments, with components chosen to maintain performance over time.

How to install Shure Microflex MX391W-A/O

  • Plan placement carefully: Position the MX391W-A/O on the table or a flat surface where participants’ voices will be closest to the microphone, while avoiding direct sources of noise and reflecting surfaces that could affect sound quality.
  • Prepare integration: Verify compatibility with your conference system, DSP, and control processor. Make sure the wiring path accommodates your room’s cabling plan and that any required control software is ready for configuration of the microphone’s I/O, LED indicators, and mute/memory functions.
  • Mount and connect: Secure the boundary microphone to its intended surface using the recommended mounting hardware. Connect the wired interface to the system’s audio input and to the control network as specified by the manufacturer’s installation guide.
  • Configure the microphone: If you plan to use the programmable membrane switches, set up their functions (mute, hold, or other room actions) via the control system or software provided by Shure or your AV integrator. Enable LED status indicators to reflect mic activity, mute status, and any programmable states for quick at-a-glance feedback during meetings.
  • Test and balance: Power on the system and perform a thorough test, speaking from typical seating positions to ensure consistent pickup across the room. Adjust gain, EQ, and any DSP routing to optimize intelligibility, while confirming that LED indicators reflect the correct states and that the device responds to logic I/O as intended.

Frequently asked questions

  • What is the MX391W-A/O best used for? It is designed for professional conference rooms, boardrooms, training spaces, and collaborative classrooms where clear, natural voice pickup is essential. The boundary form factor suits table-top installations, while its features support flexible control and easy integration with existing AV systems.
  • Can I replace or upgrade the cartridge on the MX391W-A/O? Yes. The MX391W-A/O supports interchangeable cartridges, allowing you to tailor pickup characteristics or replace a worn or damaged cartridge without replacing the entire mic. Consult your installer or Shure documentation for compatible cartridge options and procedures.
  • How do the silent membrane switches work? The switches provide mute and other control functions with quiet operation, avoiding audible clicking that can disrupt meetings. They can be programmed to perform common room actions in coordination with your control system, enabling smoother and more discreet room management.
  • Is the MX391W-A/O compatible with non-Shure equipment? Yes. The MX391W-A/O is designed to work within standard AV and conferencing ecosystems. It supports integration with digital signal processors, control systems, and other equipment common in corporate, educational, and government environments.
  • How should I care for and clean the microphone? Gently wipe the enclosure with a soft, dry cloth. Avoid liquids and harsh cleaners that could affect the finish or internal electronics. Do not disassemble the microphone unless you are an authorized technician, as this can void warranties and affect performance.

Excellent value and has saved me from the sun!
Fit Type: Regular Fit, Color: White, Size: Large
I ordered this large mans shirt because it was 100% cotton and long sleeve. I am a woman and use it to protect myself from the sun walking my dog, very stiff at first, but comes out with several washes. I love the shirt!

NICE Shirt that SHRINKS!!
Fit Type: Regular Fit, Color: Blue, Size: X-Large
Loved this shirt right out of the package. Put a little steam pressing on it and it was perfect. Has a thicker softer feel than most casual dress shirts. Ordered XL with the "regular" fit and it could be worn tucked or out without it looking overly blousy. SADLY, after a first wash on cold and tumble dry low, and pulled it out early and it shrunk by almost a full size!!! The sleeves, length of shirt and overall fittage shrunk so that now it fits like a snug large. I've never had a shirt shrink like this, hence, the one star off. I would have given it 2 stars off, but the original quality of the shirt is nice, just beware of the shrinkage factor. Don't put it in the dryer at all, only air dry it. I'm tempted to reorder another but just then never put it in the dryer.
