  • Cardioid polar pattern
  • Crisp, full-sounding voice and instrument pickup
  • Excellent gain before feedback and suppression of background noise
  • Also excels in acoustic guitar applications with guitar adapter(adapter is included with model AT831R)

Achieve crisp and full-sounding voice pickup with one of the configurations of the lavalier microphone AT831 from Audio-Technica. Excellent gain before feedback and the mic’s ability to isolate background noise make it ideal in higher SPL applications. Cardioid pattern of the condenser mic delivers quality sound reinforcement in professional recording, TV, and other demanding sound pickup locations.

Cardioid polar pattern of this lav mic has a 120° angle of acceptance. This pattern and acceptance angle allow the mic to focus in on the desired sound source while minimizing background noises to the sides and rear of the mic. Lavalier adapts to the environment with a frequency response of 40-16,000 Hz and the ability to handle sound pressure levels up to 135 dB.

Lavalier has rugged construction to withstand damages in travel or when worn. Small enough to not get in the way or be noticeable, this mic delivers the sound quality you want without feeling like a mic is in place at all. Windscreen and clothing clip are included for further sound optimization and mounting convenience. Design and microphone features make lapel mic AT831 a great choice for many public speaking uses, as well as acoustic guitar pickup when paired with AT844 guitar mount*.

All AT831 models have the features detailed above, with termination styles, cable length and power module changing depending on the model. Models with a power module can switch between flat response or low-frequency roll-off positions for further sound control. 11V to 52V of phantom power is required to operate all models except AT831b (AT831b can use phantom power or battery).

*For use with guitar mount AT844, AT831R is the compatible model.
