Creating An Eight Microphones And Stereo Video Conferencing System - Polycom SoundStructure C16 Design Manual

Creating an Eight Microphones and Stereo Video
Conferencing System
This example creates a stereo video conferencing system with eight table microphones, stereo program
audio, a VSX8000 stereo video codec, and a stereo audio amplifier. This application is similar to the 8
microphone mono example shown previously with the addition of the stereo video codec that enables both
a positional "receive" signal from the remote site and enables a positional "transmit" signal with the local
microphones that can be panned to the two output channels to encode the position of the local talker to the
remote participants.
The block diagram of this system is shown in the following figure. The channel names are labeled with the
virtual channel names that are created by default by the SoundStructure Studio software.

The steps to design this configuration are similar to the mono case with the exception of selecting stereo
program audio, a stereo VSX8000, and a stereo amplifier.
Once the design is completed, the matrix looks very similar to the mono conferencing case with the
exception that the "Program Audio", "VSX8000 In", "VSX8000 Out", and "Amplifier" virtual channels have
the stereo graphic symbol next to their names signifying they are stereo virtual channels as shown in the
following figure.
