Omnidirectional Hanging Ceiling Microphone for Clear Room Coverage
The Audix M55WO is an omnidirectional hanging ceiling condenser microphone designed to capture clear, natural speech from above in installed audio environments. Built for overhead signal pickup, it provides consistent coverage for boardrooms, lecture halls, houses of worship, classrooms, healthcare spaces, and distance learning facilities. Its hanging design keeps work surfaces clear while placing the microphone exactly where speech intelligibility is strongest.
Omnidirectional Pickup Optimized for Voice Recognition
With an omnidirectional polar pattern, the M55WO captures voices evenly from all directions beneath the microphone, making it well suited for group discussions and collaborative spaces. This pickup pattern supports voice recognition systems, video conferencing, and ambient room miking by maintaining natural tonal balance without requiring precise speaker positioning.
Integrated Low-Noise Electronics with High Sensitivity
The M55WO features a fully integrated preamp circuit engineered for high sensitivity and low self-noise. This allows effective distance miking while preserving speech clarity and detail. Balanced signal output and internal shielding provide immunity from RF interference caused by mobile phones and wireless devices, ensuring stable performance in modern AV installations.
Adjustable Hanging Length and Full Rotation Control
Designed for flexible installation, the M55WO includes adjustable mounting hardware that allows the microphone to hang up to 4 feet from the ceiling surface. Fingertip height adjustment and full 360-degree rotational control make it easy to fine-tune placement without removing ceiling tiles. An optional aiming clip is available for applications that require additional directional control.
Simple Installation with Plenum Rated Safety Design
Installation requires only a single 5/8-inch ceiling hole and no specialized tools. The microphone’s cable assembly terminates in a solderless Phoenix connector housed inside an airtight, plenum-rated metal junction box. A seismic restraint and fire safety cable are included, making the M55WO suitable for commercial buildings, educational facilities, and medical environments with strict safety codes.
Expandable System with Interchangeable Capsule Support
The M55WO supports optional interchangeable capsules, allowing users to adapt the microphone system to cardioid, hypercardioid, omnidirectional, or supercardioid pickup patterns as system needs change. This flexibility makes it a long-term solution for evolving conference, surveillance, ambient audio, and instructional applications.
