Audio Technica U851A Cardioid Condenser Boundary Microphone

Offering outstanding Audio-Technica sound for surface-mount applications, the U851A 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 microphone sets audio-quality standards in challenging acoustic environments.

Key Product Features:

• 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 rear or 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 silicone foam bottom pads 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
