This high-quality, professional-grade microphone, crafted by the reputable brand Audio-Technica, is designed specifically for surface-mount applications. It's perfect for a range of demanding sound pickup situations, including professional recording, television, conferencing, and high-quality sound reinforcement.
This stylish black microphone is phantom-powered and features a cardioid polar pattern, expertly capturing sound sources directly in front of the microphone while minimizing sound from other directions. This makes it an ideal choice for recording live performances, podcasting, or any application where you want to focus on a specific sound source.
The U851RB microphone is equipped with a PivotPoint rotating output connector, UniSteep filter, and UniGuard RFI-shielding technology, ensuring clear, transparent sound quality and outstanding speech intelligibility. It also accepts interchangeable condenser elements, available separately in hypercardioid and omnidirectional polar patterns, providing you with the flexibility to adapt to any recording situation.
Constructed with a durable, heavy die-cast case and silicon foam bottom pads, this microphone effectively minimizes the coupling of surface vibration, ensuring a stable and reliable performance. The self-contained electronics eliminate the need for an external power module, making it a convenient and efficient choice for your audio needs. Plus, the threaded inserts on the bottom of the microphone allow for secure mounting with screws, adding an extra layer of security.
