Manufacturer's Description for Audio-Technica U891R Condenser Boundary Microphone

Designed to deliver easy, flexible control in conference and boardroom installations, the versatile U891R cardioid condenser boundary microphone features a touch-sensitive on-off 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

Ultra-quiet electronic 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

Heavy die-cast case and non-slip silicon foam bottom pads minimize coupling of surface vibration to the microphone
