Assigning Digital Microphone Array Channels To Physical Inputs - Polycom SoundStructure C16 Design Manual

associated with this project is shown in the following figure.
Notice that the digital microphone arrays are shown just as any other audio channel in the system. Although
the signal level meters are active for the Polycom microphones, one difference between an analog
microphone input and a digital microphone array input to SoundStructure is that the analog gain slider is not
present on the digital microphones as shown in the following figure. The slider is not present because it does
not affect the signal level coming in from the microphone array as the signal is already digitized in the
microphone array and does not pass through the SoundStructure's analog gain stage.

Assigning Digital Microphone Array Channels To Physical Inputs

When Polycom digital microphone arrays are used within SoundStructure Studio, SoundStructure Studio
assigns the processing for each digital microphone input from a physical analog input. SoundStructure
Studio reserves processing by starting with the last analog input channel and working towards the first
analog input.
For example, if a single Polycom digital microphone array is used with a SoundStructure C12, the
processing from physical analog inputs 12, 11, and 10 are used for the digital microphone elements A, B,
and C respectively and the physical inputs 12, 11, and 10 are not able to be used for any analog inputs. If
two digital microphones are used with a C12, the second digital microphone's elements A, B, and C utilize
the processing associated with analog physical inputs 9, 8, and 7 respectively. In this example, analog input
signals may not be connected to inputs 7-12.
