An activation switch offers 3-mode operation: press-on/press-off, press to talk, and press to mute. An 80 Hz low-cut UniSteep filter reduces pickup of low-frequency ambient noise. UniGuard innovations offer immunity from radio frequency interference; available in cardioid, hypercardioid and omnidirectional polar patterns: a PivotPoint connector changes the cable exit point. Requires phantom power. A wide-range condenser microphone with a cardioid polar pattern, the U891RCx 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 devicea camera, for instancefrom a switch on the microphone.

Another ease-of-use feature: the microphone's activation switch can be set to three operating modes: touch-on/touch-off, press to talk, and press to mute. The mic is also equipped 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; interchangeable elements are available in cardioid, hypercardioid and omnidirectional polar patterns; a unique rotating PivotPoint connector changes the cable exit pointno tools required.

It requires 11 to 52V DC phantom power, which operates the microphone and switch circuitry.

An activation switch can be set to any of three operating modes: "touch-on/ touch-off," "touch-to-talk" and "touch-to-mute" External contact closure capability permits control of remote devices from microphone switch External LED control allows for accurate depiction of the live status of the microphone PivotPoint rotating output connector allows cable to exit from either the rear or the bottom of the microphone Small-diameter UniPoint capsule near boundary eliminates phase distortion.
