Featuring 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. Features: 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 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 Specifications: Element: Fixed-charge back plate, permanently polarized condenser Polar Pattern: Line Cardioid Frequency Response: 30-20,000 Hz Low Frequency Roll-Off: 80 Hz, 18 dB/octave Open Circuit Sensitivity: -35 dB (17.7 mV) re 1V at 1 Pa Impedance: 250 ohms Maximum Input Sound Level: 135 dB SPL, 1 kHz at 1% T.H.D.
