Designed for surface-mount applications such as high-quality sound reinforcement, professional recording, television, conferencing and other demanding sound pickup situations, the U851cW features a PivotPoint rotating output connector, UniSteep filter and UniGuard RFI-shielding (Radio Frequency Interference) technology. This battery or phantom powered condenser microphone accepts interchangeable condenser elements - available for boundary microphones in cardioid, hypercardioid and omnidirectional polar patterns. The small-diameter UniPoint capsule near boundary eliminates phase distortion and delivers clear, high-output performance. Its heavy die-cast case and silicon foam bottom pads minimize coupling of surface vibration to the microphone. With superior off-axis rejection and maximum gain-before-feedback, this professional microphone sets audio-quality standards in challenging acoustic environments.
