Whether you are coordinating hybrid meetings, streaming live content, or coordinating team discussions, this boundary microphone provides consistent, natural-sounding voice capture that keeps every participant heard with precision. The combination of a wide pickup pattern and a generous 25-foot range means you’ll capture voices clearly from across the table, even in larger rooms, without needing multiple mics or complicated spacing. In short, the AC-404-LED is designed to modernize your space with high-fidelity sound, simple setup, and a look that matches contemporary interiors.

• Signature 3-capsule design for crystal-clear intelligibility: The Marshall AC-404-LED uses a tri-capacitive approach to capture nuanced vocal details, reducing noise and ambient interference while preserving the natural timbre of voices in conversations, meetings, and collaborative sessions.
• Wide pickup pattern with a 25-foot range: Designed to perform in group settings, the microphone provides broad coverage so participants across the table are heard clearly. This makes it ideal for boardrooms, classrooms, and streaming setups where multiple speakers may contribute from varying distances.
• LED indicator for quick status checks: The built-in LED provides immediate visual feedback on activity and connection status, helping operators and presenters know at a glance when the mic is live and ready for action during calls, broadcasts, or gaming sessions.
• Wired boundary design for reliable placement: Engineered to sit flush on desks or conference tables, the AC-404-LED minimizes mic visibility while maximizing audio pickup from the boundary, reducing the likelihood of occlusion and ensuring stable placement in dynamic environments.
• Professional finish with versatile use cases: The classic black enclosure pairs with existing conference furniture, studio setups, and gaming rigs. Its understated, professional look makes it suitable for executive spaces, classrooms, and hybrid work environments where consistent audio quality matters most.

The AC-404-LED isn’t just a microphone; it’s a complete solution for modern audio capture. The three-capsule arrangement helps balance sensitivity and directional control, so voices are picked up clearly without pulling in excessive room noise. This is particularly valuable in hybrid meetings where participants join from different locations and equipment quality varies. In such scenarios, consistent vocal levels matter more than ever, and the AC-404-LED helps maintain that consistency. The LED indicator complements this by providing a clear, at-a-glance signal during busy conferencing sessions. The boundary design also contributes to ease of use: you can simply drop the mic onto the table surface, align it with the centerline of your group, and begin speaking. There’s no need for complex ceiling mounts or elaborate booth setups, which makes this microphone a practical upgrade for offices, education spaces, and home studios alike.

For users who demand a blend of professional audio and everyday practicality, the AC-404-LED delivers. Its construction is built to withstand the routine wear and tear of busy environments, while its sound characteristics are tuned to preserve the fidelity of human speech. Whether you’re moderating a roundtable discussion, hosting a panel, or coordinating a remote team, the microphone’s pickup efficiency helps ensure that every voice is present, clear, and easy to understand. The wired design minimizes latency and potential wireless interference, making it a dependable choice for real-time communication, live streams, and production workflows. Additionally, the neutral black finish ensures it complements a broad range of interior designs and equipment setups without drawing unnecessary attention, allowing the camera and screen to remain the focal points of the room.

In terms of versatility, the AC-404-LED shines in environments where flexible placement and reliable power are paramount. It works well with a wide array of conferencing systems, soundboards, and recording interfaces, enabling straightforward integration into existing gear inventories. The absence of batteries or external power requirements keeps the setup simple and clutter-free. For equipment managers and IT coordinators, this means fewer moving parts to manage and fewer compatibility headaches, which translates into faster deployments and lower total cost of ownership. As a result, whether your goal is to improve meeting productivity, support hybrid learning, or enhance your live-streaming audio, the AC-404-LED is a robust, user-friendly choice that respects the value of clear, intelligible speech across a variety of use cases.

how to install Marshall AC-404-LED

• Choose a stable, unobstructed boundary position on the table where the speakers are most likely to be seated. Place the microphone so its capsule array faces the area where voices will originate, ensuring coverage across the group.
• Connect the microphone to your conferencing system, audio interface, mixer, or other compatible devices using the wired connection provided. If your setup requires specific cabling (for example, XLR or 3.5 mm), use the appropriate interface as dictated by your gear, and verify that all connections are snug and secure.
• Power on the connected equipment and test the microphone by speaking from various positions around the table. The LED indicator should illuminate to show the mic is active and receiving signal.
• Adjust gain or input levels on your connected device to achieve clear, natural-sounding voice levels without clipping. Aim for consistent vocal levels across participants by testing at typical speaking distances.
• Run a quick test with other participants, checking for any room reverberation or pickup gaps. If necessary, reposition the microphone slightly toward areas with higher vocal activity to optimize coverage, or use any provided mounting or stabilizing features to maintain the boundary’s alignment.
