U857RLU

Overview

U857RLU

Designed for high-quality sound reinforcement, professional recording and broadcasting
UniLine® polar pattern provides narrow 90° 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

Features

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.
