Audio Technica U857AU
Gooseneck Micropohone

Audio Technica U857AU
G&G Price: $257
UniLine™ Condenser Gooseneck Microphone.
16.81″ length
Includes windscreen and A-Mount flange,
power module and
A-Mount cable pass-through adapter

Description:

Audio-Technica’s U857AU incorporates the most essential ingredients for quality sound reproduction for a wide range of installed applications. Equipped with A-T’s UniLine™ line-cardioid element with a tightly focused 90º acceptance angle, the U857AU features a small-diameter gooseneck with virtually no “memory.” Its ultra-flexible, robust design permits easy adjustment into desired shape while resisting inadvertent repositioning. The 16.81"-long UniLine condenser direct mounts to any 5/8"-27 stand. Featuring UniGuard™ innovations that offer unsurpassed immunity from radio frequency interference, the U857AU 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.

Features:

Designed for high-quality sound reinforcement, professional recording and broadcasting
UniLine™ polar pattern provides narrow 90º acceptance angle
Superior off-axis rejection for maximum gain before feedback
UniGuard™ RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)
Easy-to-adjust, rugged, small-diameter, alternating gooseneck with virtually no “memory” permits quick positioning into desired shape
UniSteep® filter provides a steep low-frequency attenuation to improve sound pickup without affecting voice quality
Accepts interchangeable elements to permit angle of acceptance from 90° to 360°
Two-stage foam windscreen yields dramatically improved resistance to P-pops and other breath blasts
Direct mounts to any 5/8"-27 stand, or to included threaded mounting flange
Operates on battery or phantom power
