  • Overview


    Featuring Audio-Technica’s UniLine™ line-cardioid element, the U857RU adapter-mount gooseneck condenser microphone has a small-diameter gooseneck with virtually no “memory.” Its ultra-flexible, robust design permits easy adjustment into desired shape while resisting inadvertent repositioning. The microphone direct mounts to any 5/8"-27 stand; it is 16.81” long. Equipped with UniGuard® innovations that offer unsurpassed immunity from radio frequency interference, the U857RU accepts interchangeable elements, available in cardioid, hypercardioid, omnidirectional and UniLine® line cardioid polar patterns. The phantom-powered microphone also offers an 80 Hz low-cut UniSteep® filter that reduces pickup of low-frequency ambient noise.
