Frequently Asked Questions
What are the advantages of a three-channel boundary microphone in conference rooms?
Three-channel models like the U851Rb allow flexible coverage across large conference tables with each channel independently routable. This gives you precise control over audio from different sections of the table and enables selective mixing.
What does 360° or 300° coverage mean for a boundary microphone?
360° coverage means the microphone picks up sound in all directions on the mounting surface, while 300° coverage excludes a focused rejection zone. This adjustable coverage allows you to tailor the microphone's pickup pattern to match your room layout.
How does off-axis rejection improve audio quality in theaters and studios?
Off-axis rejection minimizes pickup of unwanted sounds coming from outside the desired coverage area. This allows theater productions and recording studios to isolate the intended source (e.g., an actor or orchestra) from audience noise or stage reflections.
Is the U851Rb suitable for television broadcast environments?
Yes, the U851Rb is designed for surface-mount applications in professional broadcast settings. Its adjustable elements and rejection characteristics make it ideal for TV studio panels, talk shows, and broadcast conference applications.
What is the difference between the U851Rb and U851RbO models?
The U851Rb has adjustable cardioid elements, while the U851RbO adds omnidirectional capability to its element options. This makes the U851RbO more flexible for applications requiring both directional and omnidirectional coverage.
Does the white U851RWb perform differently from the black U851Rb model?
The U851RWb is functionally identical to the U851Rb, with the same audio performance and professional specifications. The white finish is chosen purely for aesthetic purposes in installations where visual discretion is important.
