Audio Technica U857RU

With a UniLine line cardioid element, the Audio Technica 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 inch - 27 stand; it is 16.81inch 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.
