Description
The Audio-Technica U891R is a flexible boundary microphone designed to accurately capture audio in conference hall, boardroom and classroom installations. The U891R features a half-cardioid pick up pattern, providing a generous pick up area at the surface and perimeter while eliminating structure noise and reflections off the desktop surface. The polar pattern and even frequency response results in detailed signal reproduction, regardless of the relationship between the talker and microphone positions.
A programmable membrane switch can be set for one of three functions. Push On / Push Off, Push to Mute and Push to Talk modes are all programmable by the user and add to the flexibility of the U891R. In addition to the outstanding sonic character, the U891R features a heavy die-cast case and silicon foam bottom pads that minimise vibration and surface noise. A low frequency roll-off switch eliminates proximity effect noise, low frequency hum, ambiance noise and wind noise. A pivoting output connector reveals a TB3-male connection and enables flexible surface installation. A 7.62 m TB3-female to standard XLR male cable is supplied.
Features
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) are eliminated due to specialised 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.
