Audix M40W12 Miniature Cardioid Ceiling Microphone

Cardioid Hanging Ceiling Microphone for Clear Speech Capture

The Audix M40W12 is a miniature high-output cardioid ceiling microphone with a 12-inch flexible gooseneck, designed to deliver focused, intelligible speech capture in conferencing, education, medical, and installed sound environments. Built for overhead installation, this condenser microphone provides accurate voice reproduction while remaining visually discreet, making it ideal for boardrooms, lecture halls, video conferencing systems, and distance learning applications.

Focused Cardioid Pickup for Speech and Voice Reinforcement

Equipped with a cardioid polar pattern, the M40W12 concentrates on sound directly in front of the capsule while reducing ambient noise from the sides and rear. This directional control improves speech clarity in meeting rooms and presentation spaces where background noise and room reflections can interfere with intelligibility. The tailored frequency response supports natural vocal tone, helping presenters and instructors sound clear and articulate.

12 Inch Flexible Gooseneck for Precise Positioning

The integrated 12-inch gooseneck allows installers to aim the microphone accurately toward the talker. This flexible positioning supports “point-and-shoot” directivity, ensuring optimal pickup in environments such as conference tables, hospital procedure rooms, and lecture spaces. The unobtrusive white finish blends with ceiling surfaces, maintaining a clean architectural appearance in professional AV installations.

Integrated Electronics with Low Noise and High Sensitivity

The M40W12 features a built-in preamp circuit designed for low self-noise and high sensitivity. Operating on standard 18–52V phantom power, the microphone does not require an external power adapter, simplifying installation and system integration. A 12mm gold vapor diaphragm supports consistent audio performance, delivering reliable signal output even when mounted at ceiling height for distance miking.

RF Immunity for Reliable Installed Sound Systems

Engineered with shielding to resist radio frequency interference, the M40W12 helps prevent noise caused by mobile devices and wireless electronics commonly found in conference and classroom environments. The integrated cable terminates with a Phoenix connector, supporting clean wiring and compatibility with professional DSP systems and installed audio equipment. An optional junction box is available for additional mounting flexibility.

Applications for Conferencing and Installed AV

This cardioid hanging ceiling microphone is well suited for video conferencing, distance learning, surveillance monitoring, medical procedures, ambient room miking, and corporate meeting rooms. Its combination of high output, controlled directivity, and streamlined installation makes it a dependable solution for integrators and AV professionals.
