Audio Technica AT831R
The Audio Technica AT831R is a clip-on lavalier mic that provides a crisp, full-sounding voice pickup and also excels as an instrument mic, especially for pickup of acoustic guitar with included AT8444 guitar adapter. It offers excellent gain before feedback and suppression of background noise. An integral 80 Hz high-pass filter provides easy switching from a flat frequency response to a low-end roll-off.
