Description
Omnidirectional Condenser Boundary Microphone; Phantom Power Only, Built-In Power Module
The U841R delivers exceptionally intelligible audio reproduction in a super-compact, low-profile design. Equipped with UniGuard RFI-shielding technology, this omnidirectional condenser boundary microphone is designed for clear, highly intelligible sound quality in surface-mount applications. The phantom-powered U841R is equipped with self-contained electronics, eliminating the need for an external power module.
Features:
- Designed for surface-mount applications where highly intelligible sound quality is required
- Small-diameter omnidirectional capsule near boundary eliminates phase distortion and delivers clear, high-output performance
- Superior off-axis rejection for maximum gain before feedback
- UniGuard RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)
- Self-contained electronics eliminate need for external power module
- 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 finish for minimum visibility
