Vaddio U891R UniPoint Condenser Boundary Microphone

Distributed by Vaddio, the Audio-Technica U891R UniPoint Condenser Boundary Microphone
is identical to the standard Audio-Technica distributed model and is
recommended for use with the Vaddio MicVIEW Teleconference Switcher /
Mixer system. The U891R features a half-cardioid polar pattern, LED
status indicator, programmable membrane switch and is impervious to RF
(Radio Frequency) interference.


Half-Cardioid Polar Pattern
The half-cardioid polar pattern provides a generous pick up at
the top and perimeter sections while eliminating off-axis surface noise
due to reflections.

Programmable Switch
A programmable membrane switch provides push On/push Off, push-to-talk and push-to-mute modes.

Low Frequency Roll-Off
A low frequency roll-off switch eliminates low frequency noise at 80Hz.

RFI Shielding
Noise due to Radio Frequency Interference (RFI) is eliminated
due to specialized shielding within the structure of the microphone and
cable.

Interchangeable Capsules
Optional microphone capsules are available and provide different
polar patterns. An omni-directional capsule provides a 360 degree pick
up range while the hyper-cardioid features a 100 degree area.

Vibration Resistant Base
The die-cast metal and foam pads combine to reduce noise caused by surface vibration.

Pivoting Output Connection
The pivoting output connector enables flexible surface installation, a standard XLR output cable is supplied.
