Product Description

The AT831CW is terminated with locking 4-pin connector for AT UniPak bodypack wireless transmitters.  Featuring a miniature condenser microphone with a cardioid polar pattern, the AT831CW is designed for hands-free applications in sound reinforcement systems and for use by professional musicians. The AT831CW provides improved gain before feedback that normally cannot be achieved with miniature omnidirectional microphones. Close-up voice pickup is crisp and clean, yet full sounding, while suppression of background noise is significantly improved over that of stand-mounted full-size cardioid microphones. Audio-Technica design engineers have utilized the newest low-mass technology in the quest for superior performance.


  • Clip-on lavalier condenser cardioid microphone
  • Provides crisp, full-sounding voice
  • Excellent gain before feedback and suppression of background noise

The microphone can be attached to clothing using the clip provided. An open-pore foam windscreen simply slips over the head of the microphone, effectively reducing wind noise or popping when used extra close.
