Audio-Technica is now shipping its new U841R Omnidirectional Condenser Boundary Microphone. A new addition to Audio-Technica’s acclaimed UniPoint® line of microphones, the U841R is an update to and replacement of A-T’s highly popular U841A microphone.

Audio Technica U841R 400pxWhile retaining the feature set that has made the U841A such a successful tool, the new U841R microphone is enhanced with the addition of internal electronics that do not require an external power module. The mic features an integral TA3M output connector and includes a 25' TA3F-to-XLRM cable. 

The U841R delivers exceptionally intelligible audio reproduction in a super-compact, low-profile design. Equipped with UniGuard® RFI-shielding technology, this omnidirectional condenser boundary microphone is designed to capture audio for clear, highly intelligible sound reinforcement, professional recording, television and conferencing in surface-mount applications. The U841R has a 360° pickup angle and operates on phantom power.

  • UniGuard® RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)
  • Small-diameter capsule near boundary eliminates phase distortion and delivers clear, high-output performance
  • Heavy die-cast case and silicone foam bottom pad minimize coupling of surface vibration to the microphone
