Outstanding speech intelligibility and transparent sound quality for surface-mount applications.

    Audio-Technica is 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)
