The Audio-Technica U851CW is a high quality surface-mounted boundary microphone designed for audio capturing in conference rooms, boardrooms, classrooms, stage performances, podiums, houses-of-worship and more. The sleek rugged enclosure provides a low-profile while housing a cardioid, condenser element.
The cardioid pattern is effective in minimizing noise and feedback at the off-axis sections of the microphone, resulting in greater signal to noise ratio. The UA851's capsules are interchangeable, omnidirectional and hyper-cardioid polar patterns are available. This version features an Audio-Technica CW connection for use with UniPak transmitters.
