Design Guide for the Polycom SoundStructure C16, C12, C8, and SR12
6 - 26
A summary of the cables is shown in the following table. The pin outs for the
RJ45 terminated cables 2457-24008-001 and 2457-24009-001 are shown in Chap-
ter 14 - Specifications. Both of these cables have the same pin out and differ
only in length.
Summary
This chapter has described how the Polycom HDX video conferencing system
can be connected to SoundStructure devices over the Conference Link2 inter-
face including a description of the signals and available processing.
In addition, up to four digital microphone arrays may be used with the Sound-
Structure devices to simplify any audio or video conferencing design.
The digital microphone arrays take up the processing of three analog inputs.
The following table shows the number of analog inputs that are available
based on the number of microphones that are used in a system. As an example,
a SoundStructure C16 supports 16 analog inputs. When used with two
microphone arrays, 10 analog inputs are still available for use with other
analog inputs including microphones, program audio, etc.
