Audio-TechnicaU843R Three Channel Boundary Cardioid Condenser Microphone Audio-TechnicaU843R



 Description

With three cardioid condenser elements in a single housing, the phantom-powered
U843R offers a remarkably versatile tool for surface-mount installations. Levers
on the microphone base allow easy reorientation of two elements to offer 360° or
300° coverage. Since elements can be powered and used individually or in any
combination, further flexibility is easily achieved. For example, with two elements
powered, the microphone can provide a figure-of-eight polar pattern; with a single
element powered, the microphone functions as a standard cardioid boundary
microphone. Installation and repositioning are extremely quick, thanks to four
recessed pathways on the base of the microphone that enable the user to route
the cable as required to accommodate any installation requirements; no tools or
disassembly are needed. The microphone also offers Audio-Technica’s innovative
UniGuard® RFI-shielding technology.

Features:
- Each element can be powered and used individually or in any combination
- Designed for surface-mount applications such as highquality sound reinforce
- Ideal for a variety of video and audio conferencing application
- Small-diameter UniPoint capsule near boundary eliminates phase distortion
- Technology UniGuard™ offers outstanding rejection of RFI
- Low-profile design with low-reflectance finish for minimum visibility
