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.
U841R features include:
- 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
- Low-profile design with low-reflectance black finish for minimum visibility
