DescriptionFeaturing Audio-Technica’s UniLine™ line-cardioid element with a tightly focused 90º acceptance angle, the U857QU quick-mount gooseneck condenser microphone is designed to plug directly into a panel- or desk-mounted XLRF-type connector; it is 19.17” long. Its ultra-flexible, robust gooseneck permits easy adjustment into desired shape while resisting inadvertent repositioning. Featuring UniGuard® innovations that offer unsurpassed immunity from radio frequency interference, the U857QU 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.  |
FeaturesDesigned 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
Self-contained electronics eliminate need for external power module
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
Quick-mount design with 3-pin XLRM-type connector insert at base plugs into any standard XLRF-type surface or cable connector
Included shock mount attenuates noise, shock and vibration transmitted through the mounting surface
