Audio-Technica Condenser Microphone (U873R) The U873R UniPoint hypercardioid condenser microphone offers smooth, accurate audio reproduction for handheld and fixed-mount applications. The microphone is equipped with A-Ts UniGuard technology for unsurpassed immunity from radio frequency interference. It also features an 80 Hz UniSteep filter that reduces pickup of unwanted low-frequency ambient noise. The microphones special internal shock mounting eliminates virtually all handling and cable noise. Designed for distortion-free output even in intense sound fields, interchangeable elements (cardioid, hypercardioid and omnidirectional) permit selection of angle-of-acceptance from 100 to 360. Features: Designed for high-quality sound reinforcement, professional recording and broadcasting Smooth, accurate reproduction for handheld and fixed-mount applications Superior off-axis rejection for maximum gain before feedback Hypercardioid polar pattern reduces pickup of sounds from the sides and rear, improving isolation of desired sound source Integral 80 Hz high-pass filter switch and 10 dB pad switch Accepts interchangeable elements to permit angle of acceptance from 100 to 360 Superior anti-shock engineering ensures low handling noise High sensitivity and high SPL capability Robust design for enduring dependability Specifications: Element: Fixed-charge back plate, permanently polarized condenser Polar Pattern: Hypercardioid Frequency Response: 70-20,000 Hz Low Frequency Roll-Off: 80 Hz, 18 dB/octave Open Circuit Sensitivity: -41 dB (8.9 mV) re 1V at 1 Pa Impedance: 200 ohms Maximum Input Sound Level: 155 dB SPL, 1 kHz at 1% T.H.D.
