Audio-Technica U851R Cardioid Condenser Boundary Microphone - Black

Audio-Technica U851R Cardioid Condenser Boundary Microphone Overview: Featuring breakthrough audio and mechanical design innovations, the phantom-powered U851R offers outstanding speech intelligibility and transparent sound quality for surface-mount applications The microphone is equipped with a PivotPoint® rotating output connector, UniSteep filter and UniGuard RFI-shielding technology.

It accepts interchangeable condenser elements—available for boundary microphones in cardioid, hypercardioid and omnidirectional polar patterns With a heavy die-cast case and silicon foam bottom pads to minimize coupling of surface vibration to the microphone, the U851R 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 PivotPoint rotating output connector allows cable to exit from either the rear or the bottom of the microphone 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 Small-diameter UniPoint 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 Available in two colors: black (U851R) and white (U851RW) 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: –34 dB (19.9 mV) re 1V at 1 Pa IMPEDANCE: 200 ohms MAXIMUM INPUT SOUND LEVEL: 134 dB SPL, 1 kHz at 1% T.H.D DYNAMIC RANGE (typical): 108 dB, 1 kHz at Max SPL SIGNAL-TO-NOISE RATIO: 68 dB, 1 kHz at 1 Pa PHANTOM POWER REQUIREMENTS: 11-52V DC, 4 mA typical SWITCH: Flat, roll-off WEIGHT: 9.2 oz (262 g) DIMENSIONS: 4.25" (108.0 mm) long, 3.31" (84.0 mm) maximum width, 0.91" (23.0 mm) height \n OUTPUT CONNECTOR: TB3M-type \n CABLE: 25.0' (7.6 m) long, 0.13" (3.2 mm) diameter, 2-conductor, shielded cable with TA3F and XLRM-type connectors OPTIONAL INTERCHANGEABLE ELEMENTS: UE-H hypercardioid (100°); UE-O omnidirectional (360°) ACCESSORY FURNISHED: Soft protective pouch.
