Audio-TechnicaU891RWX Cardioid Condenser Boundary Microphone with Switch, White Audio-TechnicaU891RWX



 Description

Designed to deliver easy, flexible control in conference and boardroom
installations, the versatile U891R cardioid condenser boundary microphone
features an activation switch that can be set to three modes: press-on/press-off,
press to talk, and press to mute. The phantom-powered microphone is equipped
with a unique PivotPoint® rotating output connector and an LED status indicator.
UniGuard® innovations offer unsurpassed immunity from radio frequency
interference; interchangeable elements are available in cardioid, hypercardioid and
omnidirectional polar patterns; an 80 Hz low-cut UniSteep® filter reduces pickup
of low-frequency ambient noise. The microphone’s heavy die-cast case and
silicon foam bottom pads minimize coupling of surface vibration to the microphone.
The unit’s self-contained electronics eliminate the need for an external power
module.

Features:
- Designed for surface-mount applications such as high-quality sound
reinforcement, professional recording, television, conferencing and other
demanding sound pickup situations
-An activation switch can be set to any of three operating modes: “touch-on/
touch-off,” “touch-to-talk” and “touch-to-mute”
-PivotPoint® rotating output connector allows cable to exit from either the rear or
the bottom of the microphone
- Superior off-axis rejection for maximum gain before feedback
- 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
