Accepts optional elements.
Offering outstanding Audio-Technica sound for surface-mount applications, the U851A UniPoint Boundary Microphone features a PivotPoint rotating output connector, UniSteep filter and UniGuard RFI-shielding technology. This battery or phantom powered condenser microphone accepts interchangeable condenser elements--available for boundary microphones in cardioid, hypercardioid and omnidirectional polar patterns. 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 flat microphone sets audio-quality standards in challenging acoustic environments.
Designed for surface-mount applications such as high-quality sound reinforcement, professional recording, television, conferencing and other demanding sound pickup situations
PivotPoint rotating output connector allows cable to exit from either the rearor the bottom of the microphone
Superior off-axis rejection for maximum gain before feedback
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 non-slip silicon foam bottom pads minimize coupling of surface vibration to the microphone
Low-profile design with low-reflectance black finish for minimum visibility
