U851A Cardioid Condenser Boundary Microphone description:

Offering outstanding Audio-Technica sound for surface-mount applications, the Audio-Technica U851A features a PivotPoint rotating output connector, UniSteep filter and UniGuard RFI-shielding technology. Designed for surface-mount applications such as high-quality sound reinforcement, professional recording, television, conferencing and other demanding sound pickup situations.

The battery- or phantom-powered U851A condenser microphone accepts interchangeable condenser elements - available for boundary microphones in cardioid, hypercardioid and omnidirectional polar patterns. Its heavy die-cast case and silicon foam bottom pads minimize coupling of surface vibration to the microphone. With superior off-axis rejection and maximum gain-before-feedback, this professional microphone sets audio-quality standards in challenging acoustic environments.

The main features of the U851A include:

  • 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)
  • UniSteep filter provides a steep low-frequency attenuation to improve sound pickup without affecting voice quality
  • Small-diameter UniPoint capsule near boundary eliminates phase distortion and delivers clear, high-output performance
  • 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 black finish for minimum visibility
  • Operates on battery or phantom power
  • 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
  • Signal to Noise Ratio: 72 dB, 1 kHz at 1 Pa
  • Battery Type: 1.5V AA/UM3
  • Battery Current Life: 0.4 mA / 1200 hours typical (alkaline)
  • Switch: Off, on-flat, on-roll-off
  • Cable: 25.0' (7.6 m) long (permanently attached to microphone), 0.13" (3.2 mm) diameter, 2-conductor, shielded cable with TA3F-type connector
