MuxLab MXL AC-404 USB Conference Microphone — USB conference mic, omnidirectional pickup

The MuxLab MXL AC-404 USB Conference Microphone is a compact omnidirectional microphone designed for meetings, teleconferencing and simple voice recording. It connects via USB for immediate plug-and-play operation with most modern computers and conferencing platforms. The omnidirectional pickup captures voices around a 360° radius, making it suitable for small to medium conference tables and remote collaboration settings.

Advantages

The MuxLab MXL AC-404 offers straightforward USB connectivity that requires no additional drivers on most operating systems, and omnidirectional pickup that helps ensure participants seated around a table are captured evenly. Its compact form factor fits on conference tables without taking significant space, and it is compatible with common conferencing applications for easy integration into existing meeting setups.

Suitable for

• Small to medium conference rooms and huddle spaces
• Remote meetings and video conferencing with a single-table microphone
• Voice recording for interviews, podcasts or minutes in an office environment
• Classrooms or training rooms where multiple speakers are seated around a table

When it may not be suitable

This USB omnidirectional microphone is not intended for large meeting rooms where microphone coverage needs to extend across a wide area; in larger spaces, multiple microphones or ceiling/array systems are typically required. It is also not a specialist broadcast microphone—users seeking advanced directional control, high-end studio quality or isolated single-voice pickup may require a different microphone type.

Key specifications

• Pickup pattern: Omnidirectional (360° voice capture)
• Connection: USB (plug-and-play with most computers)
• Intended use: Conference, teleconferencing, voice recording
• Physical form: Compact tabletop microphone suitable for conference tables
• Compatibility: Works with standard conferencing software on common operating systems

How to use

Place the microphone at the center of the table or within clear line of sight of participants to ensure even voice pickup. Connect the device to a computer using the USB cable; the system should recognise it as an audio input device without additional drivers in most cases. Select the MuxLab USB microphone in your operating system or conferencing application audio settings. Adjust the computer input level if necessary and run a quick test to confirm all participants are audible before starting the meeting.

What to consider before purchase

• Room size and number of participants — best for small to medium tables
• Requirement for directional versus omnidirectional pickup
• Compatibility with your operating system and conferencing software
• Need for multiple microphones or an integrated AV solution in larger rooms

Usage recommendations

For optimal performance, position the MuxLab MXL AC-404 in the centre of the participant group, avoid placing it near noisy equipment, and test input levels before a call. For rooms with more participants or higher ambient noise, consider supplementing with additional microphones or a dedicated AV system.
