Marketing Information |
|
Designed for flexible performance in
boardroom, school, government, house of worship and other installed
applications, 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 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. |
