    Product Description

    Designed to deliver easy, flexible control in conference and boardroom installations, the versatile Audio-Technica U891RX 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. This 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 U891RX'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.
