Digital Microphone Cabling Requirements - Polycom SoundStructure C16 Design Manual

Digital Microphone Cabling Requirements

are in a different room. The different microphone array elements may be
muted and used in the matrix independently as easily as if they were
traditional analog microphones.
Each digital microphone is represented as three microphones on a SoundStructure
device.
As shown in the following figure, the three microphone elements are labeled
as A, B, and C within SoundStructure Studio software environment. The
ceiling microphone arrays have an orientation dot on the band that indicates
element A. The orientation of the microphone array is only significant in stereo
or positional conferencing applications where it is important to have the
relative position of microphone elements with respect to the video
conferencing camera. See Chapter 14 for examples of stereo video
conferencing applications.
