Share

Details

Ideal for conference centers, boardrooms, courtrooms, houses of worship, and other installed applications, the U857Q is designed to plug directly into a panel- or desk-mounted XLRF-type connector. This cardioid condenser quick-mount gooseneck microphone offers unsurpassed immunity from radio frequency interference thanks to Audio-Technica’s UniGuard® innovations. The 14.47” long microphone features an ultra-flexible small-diameter gooseneck and accepts interchangeable elements, available in cardioid, hypercardioid, omnidirectional and UniLine® line cardioid polar patterns. Equipped with self-contained electronics, 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

 

    • 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
