Microphone

Audio-Technica's U857AU incorporates the most essential ingredients for quality sound reproduction for a wide range of installed applications. Equipped with Audio-Technica'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.

  • 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 threadedmounting flange
  • Operates on battery or phantom power
