The AT4047MP is a large-diaphragm side-address externally polarized (DC bias) condenser microphone with three switchable polar patterns: omnidirectional, cardioid, and figure-of-eight. It is designed to meet the most critical acoustic requirements of professional recording, broadcast and sound reinforcement.

• The omnidirectional polar pattern is sensitive to sound coming from all directions. Select the omni pattern to pick up several voices or instruments on the same microphone, to diminish proximity effect, and to preserve the location’s ambient sound.
• The cardioid polar pattern is more sensitive to sound originating directly in front of the element, making it useful in controlling feedback, reducing pickup of unwanted sounds and providing isolation between performers.
• The figure-of-eight polar pattern is more sensitive to sound originating in the front and back of the microphone, rejecting sounds from the sides. It is often used in conjunction with advanced stereo miking techniques.
