AT813a Cardioid Condenser Handheld Microphone (DISCONTINUED)

The AT813a has been updated. Click here for more information on the newest model.

The AT813a 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.
