Shure MX395AL/BI Microflex Low Profile Boundary Microphone (Brushed Aluminum, Bidirectional)

Product Overview

The Shure MX395AL/BI is a low-profile bidirectional boundary microphone designed for flush installation on conference tables, podiums, and meeting room surfaces where minimal visual footprint is essential. At just 1.25 inches (3.8 cm) in diameter, the MX395AL/BI in brushed aluminum virtually disappears on any surface while capturing speech from both sides of the microphone—making it the correct specification for conference tables where participants face each other across the table. CommShield technology provides immunity to RF interference from smartphones and wireless devices commonly present in commercial meeting environments, and phantom power operation ensures compatibility with professional mixing, DSP, and conferencing systems. For the same microphone with an integrated bi-color status LED, see the Shure MX395AL/BI-LED.

Product Description

The bidirectional (figure-8) polar pattern of the MX395AL/BI makes it the appropriate boundary microphone for conference table applications where AV system designers need a single microphone to capture participants on both sides of a table without installing two separate microphones. The pattern rejects sound from the microphone’s sides (the ends of the table), providing natural acoustic separation between the near-table pickup zone and the room environment. The brushed aluminum housing matches commercial-grade table surfaces and AV furniture commonly specified in corporate, government, and executive meeting environments. Because the microphone sits flat on the surface, it requires no stands or mounting hardware beyond the base—simplifying installation and maintaining a clean sightline across the table. CommShield technology maintains audio integrity in environments with high wireless device traffic, a practical requirement in any modern commercial meeting room.

Key Features

• Bidirectional (Figure-8) Polar Pattern — Captures speech from both sides of a conference table with a single microphone, reducing the number of microphones required for standard conference table installations and minimizing cable runs.
• Ultra-Low Profile Design — At 1.25 inches (3.8 cm) in diameter, the MX395AL/BI installs flat on any surface with minimal visual presence, preserving sightlines in boardrooms, executive suites, and government meeting rooms.
• Brushed Aluminum Finish — Professional aluminum housing coordinates with commercial AV furniture, conference tables, and boardroom aesthetics specified in corporate and government meeting environments.
• CommShield RF Interference Immunity — Guards against interference from smartphones and other portable wireless devices, maintaining consistent audio quality in modern commercial meeting environments where wireless device density is high.
• Wide Frequency Response — 50 Hz to 17 kHz frequency response captures full-bandwidth speech intelligibility for conferencing, recording, and sound reinforcement applications.
• 123 dB Maximum SPL — High SPL handling supports use in louder environments without distortion, providing headroom for meetings with poor acoustic control or adjacent noise sources.
• Logic Input for Remote LED Control — Accepts external logic control signals for remote mute status indication, enabling integration with room control systems and AV automation platforms in commercial installations.
• Phantom Power Operation — Operates on standard 11–52 V DC phantom power, compatible with professional mixing consoles, DSP processors, and digital conferencing systems.
