Description
The U841A 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 for clear, highly intelligible sound reinforcement, professional recording, television and conferencing in surface-mount applications. The U841A has a 360° pickup angle and operates on battery or phantom power.Designed for surface-mount applications such as high-quality sound reinforcement, professional recording, television, conferencing and other demanding sound pickup situations
UniGuard® RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)
UniSteep® filter provides a steep low-frequency attenuation to improve sound pickup without affecting voice quality
Small-diameter UniPoint® 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
Operates on battery or phantom power
