Design Guide for the Polycom SoundStructure C16, C12, C8, and SR12
Input Channels From The Polycom HDX
6 - 4
Once the Polycom HDX video system is selected, four SoundStructure input
virtual channels are automatically added to the input channels as shown in the
next figure. If a particular input channel is not going to be used, for example
the HDX PSTN In channel, that channel may be removed from the input chan-
nels without affecting the other input channels from the Polycom HDX video
system.
