U891Rb

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.

Available configurations:

U891Rb: cardioid polar pattern (120° acceptance angle); black finish.

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

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

Eigenschappen

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
