Features
The 16.58″ version of U857R, the U857RL cardioid condenser adapter-mount gooseneck microphone 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. 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.
