The AT4047/SV is a large-diaphragm side-address externally polarized (DC bias) condenser microphone with a cardioid polar pattern. It is designed to meet the most critical acoustic requirements of professional recording, broadcast and sound reinforcement.The microphone requires 48V phantom power for operation.The cardioid polar pattern of the microphone 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 output of the microphone is a 3-pin XLRM-type connector.The microphone is equipped with a switchable 10 dB pad and a switch that permits choice of flat response or low-frequency roll-off (via integral 80 Hz high-pass filter).The microphone is enclosed in a rugged housing. The included AT8449/SV shock mount provides superior isolation and permits mounting on any microphone stand with 5/8"-27 threads. A dust cover and a protective carrying case are also included.
