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.
