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.
