Cardioid Condenser Boundary Microphone (white)

U851RWb
  • Cardioid condenser boundary microphone
  • Designed for surface-mount applications such as high-quality sound reinforcement, professional recording, television, conferencing and other demanding sound pickup situations
  • Superior off-axis rejection for maximum gain before feedback
  • PivotPoint™ rotating output connector allows cable to exit from either the rear or the bottom of the microphone
  • Small-diameter UniPoint™ capsule near boundary eliminates phase distortion and delivers clear, high-output performance
  • UniGuard™ RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)
  • 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
  • Threaded inserts on bottom of microphone allow it to be mounted with screws for increased security
  • White color case
