Audio Technica Microphone - Unipoint Gooseneck Microphone - U857R Cardioid Condenser Adapter-Mount, 3-Pin XLRM Connector, 250 ohms, phantom-power, Designed for high-quality sound reinforcement, Easy-to-adjust, rugged, small-diameter.

The high-performance U857R features a small-diameter gooseneck with virtually no “memory.” Its ultra-flexible, robust design permits easy adjustment into desired shape while resisting inadvertent repositioning. This cardioid condenser adapter-mount gooseneck microphone direct mounts to any 5/8"-27 stand; it is 16.58” long. Equipped with UniGuard™ innovations that offer unsurpassed immunity from radio frequency interference, the U857R 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.
