Audio-Technica U857RLU

UniLine® Condenser Adapter-mount Gooseneck Microphone

370.00

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.

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
