Audio Technica U857R
Designed for flexible performance in boardroom, school, government, house of worship and other installed applications, the high-performance Audio Technica 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 12.01" 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.
