Audio Technica AT831CW Cardioid Lavalier Microphone

Product Description

The Audio Technica AT831CW is a cardioid lavalier microphone designed for wireless transmitter systems. It delivers directional audio pickup in a compact, clip-on form factor suited for broadcast, presentation, and live sound applications. The cardioid polar pattern focuses pickup on the sound source directly in front of the capsule, reducing ambient noise and feedback. Its small profile and low-profile clip allow discreet placement on clothing, making it a reliable choice for installers and audio technicians working in professional AV environments.

The AT831CW is intended for use with compatible wireless bodypack transmitters, making it well suited for presenters, performers, and on-camera talent in both fixed installation and touring scenarios. It fits residential and commercial AV applications including houses of worship, corporate presentation systems, and broadcast production. Audio technicians and AV integrators typically deploy this microphone as part of a complete wireless mic system where a discreet, hands-free solution is required.
