Audio Technica U891RWB Cardioid Condenser Microphone

The Audio Technica U891RWB is professionally designed to deliver flexible, easy control in boardroom and conference installations, the versatile U891RWb cardioid condenser boundary microphone comes with a touch-sensitive capacitive-type user switch designed to be able to be set to three modes: touch to mute, touch on/off, and touch to talk. The phantom-powered microphone is created with built-in unique PivotPoint® rotating output connector and a two-state RGB LED status indicator. UniGuard® innovations are offering unsurpassed immunity from radio frequency interference; also additional interchangeable elements are available separately in omnidirectional and hypercardioid polar patterns; an 80 Hz low-cut UniSteep® filter is designed for reducing the pickup of low-frequency ambient noise. The microphone’s silicon foam bottom pads and heavy die-cast case minimize coupling of surface vibration to the microphone, at the same time threaded inserts on the bottom of the microphone are allowing the mic's case to be mounted using screws for increased security. The unit’s self-contained electronics are intended for eliminating the need for an external power module.

FEATURES

  • Cardioid condenser boundary microphone with touch-sensitive capacitive-type user switch
  • Designed for surface-mount applications such as high-quality sound reinforcement, professional recording, television, conferencing and other demanding sound pickup situations
  • The capacitive touch switch can be set to any of three operating modes: touch on/off, touch to talk and touch to mute
  • Integral, phantom-powered, two-state RGB LED indicator displays on/off status of microphone
  • Superior off-axis rejection for maximum gain before feedback
  • PivotPoint® rotating output connector allows cable to exit from either the rear or the bottom of the microphone
  • Small-diameter UniPoint® element near boundary eliminates phase distortion and delivers clear, high-output performance
  • Available interchangeable elements permit angle of acceptance from 100° to 360°
  • 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 silicone foam bottom pads minimize coupling of surface vibration to the microphone
  • Low-profile design with low-reflectance finish for minimum visibility
  • Threaded inserts on bottom of microphone allow it to be mounted with screws for increased security
