Audio Technica U851RO Omnidirectional Condenser Boundary Microphone
Product Code: U851RO
Features
• Designed for surface-mount applications
• Low-profile element provides uniform omnidirectional polar pattern with 360º acceptance angle
• PivotPoint® rotating output connector
• UniGuard® RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)
• Self-contained electronics eliminate need for external power module
• Small-diameter UniPoint® capsule near boundary
• Heavy die-cast case and non-slip silicone foam bottom pads
• Low-profile design with low-reflectance finish for minimum visibility
Featuring breakthrough audio and mechanical design innovations, the phantom-powered U851RO offers outstanding speech intelligibility and transparent sound quality for
surface-mount applications. The omnidirectional microphone is equipped with a PivotPoint® rotating output connector, UniSteep® filter and UniGuard® RFI-shielding technology. It accepts
interchangeable condenser elements in cardioid and hypercardioid polar patterns. With a heavy die-cast case and silicon foam bottom pads to minimize coupling of surface vibration to the microphone, the
U851RO is equipped with self-contained electronics, eliminating the need for an external power module. |
