Audio-Technica Condenser Microphone (U851RO) Featuring breakthrough audio and mechanical design innovations, the phantom-powered U851RO offers outstanding speech intelligibility and transparent sound quality for surface-mount applications. The omnidirectional microphone is equipped with a Pivot Point rotating output connector, Unsteer filter and Unfigured RFI-shielding technology. It accepts interchangeable condenser elements in cardioid and hyper cardioid polar patterns. With a heavy die-cast case and silicon foam bottom pads to minimize coupling of surface vibration to the microphone, the U851RO is equipped with self-contained electronics, eliminating the need for an external power module. Features: Designed for surface-mount applications such as high-quality sound reinforcement, professional recording, television, conferencing and other demanding sound pickup situations Low-profile element provides uniform omnidirectional polar pattern with 360 acceptance angle Pivot Point rotating output connector allows cable to exit from either the rear or the bottom of the microphone 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 Self-contained electronics eliminate need for external power module Small-diameter Unpoint capsule near boundary eliminates phase distortion and delivers clear, high-output performance Heavy die-cast case and non-slip silicone foam bottom pads minimize coupling of surface vibration to the microphone Low-profile design with low-reflectance finish for minimum visibility Specifications: Element: Fixed-charge back plate, permanently polarized condenser Polar Pattern: Half-cardioid (cardioid in hemisphere above mounting surface) Frequency Response: 30-20,000 Hz Low Frequency Roll-Off: 80 Hz, 18 dB/octave Open Circuit Sensitivity: -31 dB (28.2 mV) re 1V at 1 Pa Impedance: 200 ohms Maximum Input Sound Level: 132 dB SPL, 1 kHz at 1% T.H.D.
