UniLine® Condenser Adapter-mount Gooseneck Microphone (21.38" Long)
The 21.38" version of U857RU, the U857RLU UniLine condenser adapter-mount gooseneck microphone features Audio-Technica’s UniLine™ line-cardioid element. The microphone’s ultra-flexible, robust, small-diameter gooseneck permits easy adjustment into desired shape while resisting inadvertent repositioning. The microphone direct mounts to any 5/8"-27 stand. Equipped with UniGuard® innovations that offer unsurpassed immunity from radio frequency interference, the U857RLU 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.
