Design Guide for the Polycom SoundStructure C16, C12, C8, and SR12
3 - 14
As an example of using physical channels, virtual channels, and virtual chan-
nel groups, consider a SoundStructure C12 device where there are ten
microphone inputs, a telephony interface, and a Polycom HDX system as
shown in the following figure.
In this example, there is a wireless microphone and a podium microphone,
both reinforced into the room, eight table top microphones, and a stereo VCR
for audio playback. As shown in this figure the system is wired with the wire-
less microphone in input 1, the podium mic on input 2, the table mics 1-8 on
inputs 3-10, a stereo VCR is connected to inputs 11 and 12 and a Polycom HDX
video codec is connected over the digital ConferenceLink interface.
