Product Overview
Very versatile both in application and operation.
- Designed for surface-mount applications such as high-quality sound reinforcement, conferencing, distance learning and other demanding sound pickup situations
Ultra-quiet electronic 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 and delivers clear, high-output performance
UniGuard RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)
Small-diameter UniPoint capsule near boundary eliminates phase distortion and delivers clear, high-output performance
Heavy die-cast case and non-slip silicon foam bottom pads minimize coupling of surface vibration to the microphone
Low-profile design with low-reflectance finish for minimum visibility
Product Details
Audio-Technica U891RC UniPoint Cardioid Condenser Boundary Microphone with Local or Remote Switching
A wide range condenser microphone with a cardioid polar pattern, the ultra-smart Audio-Technica 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 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 and 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.
