Product file
Clip-on microphone for amplified, crisp vocals. Also provides excellent results as an instrument microphone, especially for use with acoustic guitar, with the included AT8444 instrument adapter. Excellent pre-hook gain and background noise suppression. UniSteep® filter provides excellent low-frequency rolloff, improving recording quality without compromising vocal quality. For use as a lapel microphone, attach the microphone about six inches below your chin. Position it so that when the wearer moves, it is not covered by or rubbing against clothing.
