Audio-TechnicaU891RCX Cardioid Condenser Boundary Microphone with Local or Remote Switch Audio-TechnicaU891RCX



 Description

A wide range condenser microphone with a cardioid polar pattern, the ultra-smart
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 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; 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 52V DC phantom power, which operates the
microphone and switch circuitry.

Features:
- Designed for surface-mount applications such as sound reinforcement
- Ultra-quiet electronic switch
- 3 operating modes: Touch-on/ touch-off ; Touch-to-talk and Touch-to-mute
- External contact closure capability permits control of remote devices
- UniGuard® RFI-shielding technology offers outstanding rejection
- External LED control allows for accurate depiction of the live status
