The Audio-Technica U857Q is a flexible gooseneck microphone designed for outstanding performance in schools, houses-of-worship, boardrooms, government facilities, etc. The microphone capsule features a cardioid polar pattern for superb rejection of off-axis noise and ambiance.
The wide, linear frequency response delivers smooth, accurate reproduction of speech without noise, artifacts or colorization. The ultra flexible gooseneck enables flexible positioning while resisting inadvertent repositioning. Optional interchangeable capsules provide cardioid, hyper-cardioid, omni-directional and UniLine cardioid polar patterns for added flexibility.
