Audio Technica U851A
Audio Technica U851A Description:
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.
Audio Technica U851A 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 silicon 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
