Audio Technica U891R Condenser Boundary Microphone with Switch

The Audio Technica U891R Condenser Boundary Microphone delivers easy, flexible control in conference and boardroom installations.
The U891R cardioid condenser boundary microphone features a touch-sensitive on-off switch that can be set to three modes: press-on/press-off, press to talk, and press to mute. The phantom-powered microphone is equipped with a unique PivotPoint rotating output connector and an LED status indicator. UniGuard innovations offer unsurpassed immunity from radio frequency interference and an 80 Hz low-cut UniSteep filter that reduces pickup of low-frequency ambient noise. The microphone’s heavy die-cast case and silicon foam bottom pads minimize coupling of surface vibration to the microphone. The unit’s self-contained electronics eliminate the need for an external power module.

Audio Technica U891R Features

  • Designed for surface-mount applications such as high-quality sound reinforcement, professional recording, television, conferencing and other demanding sound pickup situations
  • Ultra-quiet electronic switch can be set to any of three operating modes: touch-on/ touch-off, touch-to-talk and touch-to-mute
  • 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)
  • 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 finish for minimum visibility
