U891RCx

Cardioid Condenser Boundary Microphone with Local or Remote Switching

A wide range condenser microphone with a cardioid polar pattern, the ultra-smart U891RCx is equipped with local or remote switching options. For flexible control in conference and boardroom installations, the unit's external contact closure ability allows a user to trigger an external device - a camera, for instance - from a switch on the microphone. Another ease-of-use feature: the microphone's electronic on-off switch can be set to three operating modes: touch-on/touch-off, press to talk, and press to mute. The mic is also equipped an 80 Hz low-cut UniSteep® filter to reduce pickup of low-frequency ambient noise. Its red LED status indicator can be controlled remotely. UniGuard® innovations offer unsurpassed immunity from radio frequency interference; interchangeable elements are available in cardioid, hypercardioid and omnidirectional polar patterns; a unique rotating PivotPoint® connector changes the cable exit point - no tools required. It requires 11 to 52V DC phantom power, which operates the microphone and switch circuitry.

  • 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: "touch-on/ touch-off," "touch-to-talk" and "touch-to-mute"
  • External contact closure capability permits control of remote devices from microphone switch
  • External LED control allows for accurate depiction of the live status of the microphone
  • 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
