The AT8031 is ideal for close-up
interviews, vocals, overheads,
piano, and strings. Its cardioid
polar pattern reduces pickup of
sounds from the sides and rear,
improving isolation of desired
sound source. The mic’s
proximity effect provides added
warmth when used close up.
Features include a large
protective screen that reduces
“popping” and sibilant
distortion. It operates on
battery or phantom power.
