Description

Cardioid Condenser Boundary Microphone with Local or Remote Switching

A wide-range condenser microphone with a cardioid polar pattern, the U891RCb is equipped with local and remote switching options. Locally, the microphone’s touch-sensitive capacitive-type user switch can be set to three operating modes: touch-on/touch-off, press to talk, and press to mute. For enhanced control in conference and boardroom installations, the unit’s external contact closure capability allows a user to trigger an external device – a camera, for instance – from the microphone’s user switch. The phantom-powered mic is also equipped with an 80 Hz low-cut UniSteep® filter to reduce pickup of low-frequency ambient noise. Its two-state RGB LED status indicator can be controlled remotely. UniGuard® innovations offer unsurpassed immunity from radio frequency interference; additional interchangeable elements are available separately in hypercardioid and omnidirectional polar patterns; a unique PivotPoint® rotating connector changes the cable exit point – no tools required. The microphone’s heavy die-cast case and silicon foam bottom pads minimize coupling of surface vibration to the microphone, while threaded inserts on the bottom of the microphone allow it to be mounted with screws for increased security. The unit’s self-contained electronics eliminate the need for an external power module.

Key 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
  • Logic I/O capability permits control of remote devices from the microphone’s touch-sensitive capacitive-type user switch
  • 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, which can be controlled locally or remotely, 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
