audio-technica U857RU | Threadmount Condenser, 17" CardiodSKU: U857RU
Features
UniLine™ Condenser Adapter-mount Gooseneck Microphone
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.
