Specs for wired version below:
The U841A delivers exceptionally intelligible audio reproduction in 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 360 degrees 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 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 silicon foam bottom pad minimize coupling of surface vibration to the microphone
– Low-profile design with low-reflectance black finish for minimum visibility
– Operates with Audio Technica Unipack transmitter also available with shorter cable just note desired length in order comments
