A wide range condenser microphone with a cardioid polar pattern, the Audio-Technica U891RCx Cardioid Condenser Boundary Microphone is equipped with local or remote switching options. For flexible control in conference and boardroom installations, the unit's external contact closure ability allows the user to trigger an external device-a camera, for instance, from 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 point-no tools required. It requires 11 to 52 V DC phantom power, which operates the microphone and switch circuitry.
