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.

U891RbO: omnidirectional polar pattern (360° acceptance angle); black 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

Winner, Winner! say My Three Dogs
Size: 3.8 Ounce (Pack of 1), Style: Sweet Potato, Ring
I'm always looking for different treats for my three dogs (10, 20 and 30 pounds, I don't ever recall giving my dogs anything with a pumpkin flavor, so I decided to trythese i-paw pumpkin flavored treats (I got the rings). All three of my dogs took the treat immediately and went off into their separate corners to chew away (one of my dogs is pretty fussy, so I was surprised she took it without hesitation). I'm no expert in dog treat ingredients, but I didn't see anything on the ingredients list that looked objectionable. While advertised as a rawhyde replacement, these rings don't last anywhere near as long as a rawhide, so while my dogs didn't wolf them down as fast as a conventional treat, they weren't left occupied for the half hour that a rawhide of this size might have kept them entertained (except for one of my dogs, who took an hour to finish hers, but she only has 7 teeth left in her mouth, so that's not really a fair comparison). I wouldn't hesitate to order these treats again for my pups.

Lab tested. Lab approved. WAY too expensive.
Size: 3.8 Ounce (Pack of 1), Style: Sweet Potato, Ring
My dog likes these. But they don't really last all that long. And the package only included 5-6 rings. So that's an expensive treat, when I can get a bag of 40 dental treats (5" sticks) for the same price. Would I buy these again? No

Small ingredient list -- BIG taste!
Size: 3.8 Ounce (Pack of 1), Style: Sweet Potato, Ring
This snack is tasty, given its simple formula of sweet potatoes, turkey, coconut, and soy protein isolate. The bag arrived at the house, and the girls were instantly ready for the latest and newest snack. There were four treats total in my bag - one for each baby. The smallest one (20 lbs), ironically, disappeared her treat faster than her three larger siblings (40 lbs). The bigger dogs savored their treats with smelling, licking, tasting, and chomping with elation on these tasty new treats. These chewies satisfy your girls between meals, which I noticed by them not bugging me for food hours before dinner. These seemed to do the trick and hold them over. A great appetizer, in my opinion.
