Designed to deliver easy, flexible control in conference and boardroom installations, the versatile U891Rb condenser boundary microphone features a touch-sensitive capacitive-type user switch that can be set to three modes: touch on/off, touch to talk, and touch to mute. The phantom-powered microphone is equipped with a unique PivotPoint® rotating output connector and a two-state RGB LED status indicator. UniGuard® innovations offer unsurpassed immunity from radio frequency interference; additional interchangeable elements are available separately in omnidirectional (360°), cardioid (120°), and hypercardioid (100°) polar patterns; an 80 Hz low-cut UniSteep® filter reduces pickup of low-frequency ambient noise. 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.

U891RWb: cardioid polar pattern (120° acceptance angle); white finish.

  • 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

Built to Last
Color: Black
When purchasing little practical and intentional pieces... it's easy to pick something of lesser value. Looking at all other styles and options, you see buttons and Velcro and magnets and they look enticing. But at the end of the day, you want the satisfaction of knowing you made the right choice. Pay a little extra and get what you want. This little tray will be in your possession for years to come. It's clean and sturdy and classy. Maybe a 2-tone color palette would be a nice option for future builds.

Light Weight CarryAll
Color: Brown
Being Retired I'm always home and throughout my day i settle in different spots in my house to do different tasks or activities like exercise. I found myself either carrying a bunch of small things from room to room or having to walk all the way back to my previous, I call "perch," to fetch my phone, reading glasses, stylus, pillbox, tumbler of tea, and yes, pen & paper! Now with this catch all, I just load it up in seconds and I'm good to go!!!
