Audio Technica U891Rx Cardioid Condenser Boundary Microphone

Audio Technica U891R Cardioid Condenser Boundary Microphone

Audio Technica U891R Cardioid Condenser Boundary Microphone Details
The Audio Technica U891R Cardioid Condenser Boundary Microphone is designed to deliver easy, flexible control in conference and boardroom installations. The versatile Audio Technica U891R Cardioid Condenser Boundary Microphone features a touch-sensitive on-off switch that can be set to three modes: press-on/press-off, press to talk, and press to mute. The phantom-powered microphone is equipped with a unique PivotPoint® rotating output connector and an LED status indicator. UniGuard® innovations offer unsurpassed immunity from radio frequency interference; interchangeable elements are available in cardioid, hypercardioid and omnidirectional polar patterns; an 80 Hz low-cut UniSteep® filter reduces pickup of low-frequency ambient noise. The Audio Technica U891R Cardioid Condenser Boundary Microphoneâ??s heavy die-cast case and silicon foam bottom pads minimize coupling of surface vibration to the microphone. The unitâ??s self-contained electronics eliminate the need for an external power module.
 
Audio Technica U891R Cardioid Condenser Boundary Microphone Features
  • Designed for surface-mount applications such as high-quality sound reinforcement, professional recording, television, conferencing and other demanding sound pickup situations
  • Ultra-quiet electronic switch can be set to any of three operating modes: â??touch-on/ touch-off,â?ť â??touch-to-talkâ?ť and â??touch-to-muteâ?ť
  • PivotPoint® rotating output connector allows cable to exit from either the rear or the bottom of the microphone
  • Superior off-axis rejection for maximum gain before feedback
  • UniGuard® RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)
  • Small-diameter UniPoint® capsule near boundary eliminates phase distortion and delivers clear, high-output performance
  • 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
  • Available in two colors: black (U891R) and white (U891RW)
