Audio Technica U891R
Audio Technica U891R Description:
Cardioid Condenser Boundary Microphone with Switch.
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.
Audio Technica U891R 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
- Low-profile design with low-reflectance finish for minimum visibility
- Available in two colors: black (U891R) and white (U891RW)
