Audio-Technica U841R Omnidirectional Condenser Boundary Microphone

Omnidirectional Condenser Boundary Microphone; Phantom Power Only, Built-In Power Module The U841R delivers exceptionally intelligible audio reproduction in a super-compact, low-profile design. Equipped with UniGuard RFI-shielding technology, this omnidirectional condenser boundary microphone is designed for clear, highly intelligible sound quality in surface-mount applications. The phantom-powered U841R is equipped with self-contained electronics, eliminating the need for an external power module. Features: Designed for surface-mount applications where highly intelligible sound quality is required Small-diameter omnidirectional capsule near boundary eliminates phase distortion and delivers clear, high-output performance Superior off-axis rejection for maximum gain before feedback UniGuard RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI) Self-contained electronics eliminate need for external power module Heavy die-cast case and non-slip silicon 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: Omnidirectional in hemisphere above mounting surface Frequency Response: 40-20,000 Hz Low Frequency Roll-Off: 80 Hz, 18 dB/octave Open Circuit Sensitivity: -35 dB (17.7 mV) re 1V at 1 Pa Impedance: 200 ohms Maximum Input Sound Level: 130 dB, 1 kHz at 1% T.H.D. Dynamic Range (typical): 105 dB, 1 kHz at Max SPL Signal-to-Noise Ratio: 69 dB, 1 kHz at 1 Pa Phantom Power Requirements: 11-52V DC, 2 mA typical Weight (Microphone): 84 g (3.0 oz) Dimensions (Microphone): 65.0 mm (2.56") diameter, 15.1 mm (0.59") maximum height Output Connector: TB3M-type Cable: 7.6 m (25.0') long, 3.2 mm (0.13") diameter, 2-conductor, shielded cable with TA3F-type and XLRM-type connectors Accessory Furnished: Soft protective pouch
