Design Guide for the Polycom SoundStructure C16, C12, C8, and SR12
In this example, up to six analog inputs can be used (three analog inputs are
presently in use) in addition to the two HDX ceiling microphones.
The digital microphone array elements can be moved on the wiring page to
different physical inputs if desired by clicking and dragging the microphone
to move it to a different physical input. The following figure shows moving
Ceiling Mic 1 A from input 12 to input 5 to make it possible to connect an
analog input to input 12.
If any changes are made to the wiring page, please make sure to save the file
from the File Save menu option so that the updated virtual channel definitions
are saved in the configuration.
