AT831CW Beltpack Lavaliere Instrument Mic
The Audio-Technica AT831cW is a miniature cardioid condenser microphone engineered for close-miking instruments in live sound, broadcast, and installed audio environments. Its compact, low-profile design allows unobtrusive placement on a wide range of acoustic instruments â from guitar, piano, and strings to brass, woodwinds, and percussion â without impeding the performer.
The cardioid polar pattern provides excellent off-axis rejection, minimising bleed from adjacent sources and enhancing gain-before-feedback in demanding stage environments. A smooth, extended frequency response of 40 Hz â 20 kHz captures the full tonal character of acoustic instruments with clarity and natural detail.
Terminated with a 4-pin HRS-type connector, the AT831cW is purpose-built for direct connection to Audio-Technica UniPak body-pack wireless transmitters, making it an ideal choice for performers who require cable-free mobility. The included UniMount clothing clip and AT8444 violin mount provide versatile, secure attachment options for a variety of deployment scenarios.
