Marketing Information |

Engineered for versatile positioning and
extremely flexible performance in boardroom, school, government,
house-of-worship and other installed applications, the U857AL 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 gooseneck microphone
direct mounts to any 5/8"-27 stand; it is 16.58" long. Equipped with
UniGuard® innovations that offer unsurpassed immunity from radio
frequency interference, the U857AL accepts interchangeable elements,
available in cardioid, hypercardioid, omnidirectional and UniLine™ line
cardioid polar patterns. The battery- or phantom-powered microphone also
offers an 80 Hz low-cut UniSteep® filter that reduces pickup of
low-frequency ambient noise. |
