The white version of U853RU, the U853RWU Aniline condenser hanging microphone features Audio-Technician's Aniline line-cardioid element and is equipped with Unfigured innovations that offer unsurpassed immunity from radio frequency interference. The phantom-powered microphone accepts interchangeable elements, available in cardioid, hyper cardioid, omnidirectional and Aniline line cardioid polar patterns. Its 80 Hz low-cut Unsteer filter reduces pickup of low-frequency ambient noise. Features: Designed for suspension over choirs, instrumental groups and theater stages Aniline polar pattern provides narrow 90° acceptance angle Superior off-axis rejection for maximum gain before feedback Unfigured RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI) Unsteer 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° Low-profile design with low-reflectance finish for minimum visibility 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.
