DESCRIPTION
Audio-Technica delivers reliable 360° pickup from a single, low-profile surface-mount unit with the U843R three-element boundary condenser microphone. Featuring three precision UniPoint cardioid capsules spaced at 120° intervals, this microphone provides seamless hemispherical coverage — making it an ideal centerpiece for conference tables, boardrooms, and courtroom installations where multiple talkers must be captured from a single pickup point.
The U843R eliminates the need for multiple discrete microphones, reducing channel count and simplifying system design for integrators and installers. Its permanently attached cable terminates in a professional 3-pin XLR connector, and the included in-line power module provides a switchable 80 Hz low-cut filter to manage HVAC rumble and table vibration common in real-world installed environments.
- Three cardioid condenser elements arranged at 120° for full 360° boundary coverage
- UniGuard® RFI-shielding technology for rejection of radio frequency interference
- Local touch mute switch with LED status indicator ring for intuitive user control
- Phantom powered (11–52V DC) for universal compatibility with mixing consoles and DSPs
- Low-profile housing designed to sit unobtrusively on conference surfaces
- Switchable low-cut filter (80 Hz) on the included power module
A proven solution for AV integrators seeking clean, consistent voice capture across demanding conferencing and installed sound applications.
