  • Overview


    The U891RW has been updated. Click here for more information on the newest model.

    The white-finished version of U891R, the versatile U891RW 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 an innovative 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. A heavy die-cast case and silicon foam bottom pads minimize coupling of surface vibration to the microphone. The unit’s self-contained electronics eliminate the need for an external power module.
  • 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: “touch-on/ touch-off,” “touch-to-talk” and “touch-to-mute”

    • 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 silicone 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)
