Audix M55WHC Hypercardioid Hanging Ceiling Microphone

Hanging Ceiling Microphone for Clear Overhead Speech Capture

The Audix M55WHC is a hypercardioid hanging ceiling condenser microphone designed to deliver focused, intelligible speech pickup in installed audio environments. It is built for overhead placement in spaces such as boardrooms, lecture halls, houses of worship, classrooms, and medical facilities where discreet mounting and consistent voice clarity are required.

Hypercardioid Pickup That Reduces Room Noise

The M55WHC features a hypercardioid polar pattern that tightly focuses audio capture on the sound source below the microphone. This directional response helps minimize reflections and ambient noise from surrounding areas, making it well suited for voice reinforcement, conferencing, and speech recognition systems in acoustically challenging rooms.

Integrated Electronics with High Sensitivity Performance

Fully integrated preamp circuitry inside the microphone provides high sensitivity with low self-noise, allowing it to capture spoken word clearly from a distance. The balanced output design helps prevent signal degradation while maintaining consistent performance across long cable runs commonly required in ceiling installations.

Adjustable Hanging Design for Precise Placement

The adjustable mounting hardware allows the microphone to hang up to four feet from the ceiling surface without removing ceiling tiles. Fingertip height adjustment and full 360-degree rotational control make it easy to position the microphone directly over presenters, tables, or audience areas. An optional aiming clip can be added for additional directional adjustment when needed.

Reliable Operation with RF Interference Protection

The M55WHC is engineered with immunity from RF interference caused by mobile phones, wireless devices, and GSM signals. This ensures stable performance in modern environments filled with wireless technology. Phantom power operation removes the need for external power supplies, simplifying system design.

Plenum-Rated Hardware for Permanent Installations

The microphone cable assembly terminates in a solderless Phoenix connector housed within a sealed, plenum-rated junction box suitable for commercial and institutional installations. A built-in seismic restraint and fire safety cable add an extra layer of security, making the M55WHC appropriate for regulated building environments.
