Audio-technica U857R Cardioid Condenser Adapter-mount Gooseneck
Microphone
Designed for flexible performance in boardroom, school, government, house of worship and other installed applications, the high-performance U857R from Audio-Technica 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 phantom-powered podium microphone also offers an 80 Hz low-cut UniSteep filter that reduces pickup of low-frequency ambient noise.
