A wide range condenser microphone with a cardioid polar pattern, the ultra-smart U891RC is equipped with local or remote switching options. For flexible control in conference and boardroom installations, the unit's external contact closure ability allows a user to trigger an external device-a camera, for instance-from a switch on the microphone. Another ease-of-use feature: the microphone's electronic on-off switch can be set to three operating modes: touch-on/touch-off, press to talk, and press to mute. The mic is also equipped with an 80 Hz low-cut UniSteep® filter to reduce pickup of low-frequency ambient noise. Its red LED status indicator can be controlled remotely. UniGuard® innovations offer unsurpassed immunity from radio frequency interference; a unique rotating PivotPoint® connector changes the cable exit point-no tools required. It requires 11 to 52V DC phantom power, which operates the microphone and switch circuitry. Included furnished accessory: soft protective pouch.
