March 27, 2023

OVERVIEW: Noise cancellation/reduction/denoise is an essential function of microphones. It can help you to get clearer audio, but in some scenes, you may need to record the ambient sounds. A button is designed to turn on/off the Active Noise Cancellation(ANC) function on Lark M1.

(1) Short press the button  to turn on the ANC function, and TX’s indicator will turn green from blue.

(2) Short press this button ① again to turn off the ANC function, and TX’s indicator will turn back to blue from green.
