Polycom soundstructure C8 Application Note

Application Note
Integrating Polycom SoundStructure with the ATX
and ATX SDK Immersive Telepresence Systems
Introduction
This application note describes how to integrate a SoundStructure C-series device with an ATX 300 and
the ATX 200, 300, and 400 SDK telepresence systems, collectively referred to as an 'ATX system' in this
application note. The SoundStructure Studio configuration required and the physical interconnect for
successful integration is described. The example SoundStructure configuration file is available for
download directly from Polycom's website [1].
The addition of a SoundStructure system to an ATX system enables an integrator to extend the
capabilities of the ATX system through:
•
Adding additional Polycom microphone arrays, analog microphones, presentation microphones,
wireless microphones, push-to-talk microphones, telephony interfaces, overflow room support,
additional loudspeaker zones, logic output applications, and more.
•
Adding more in-room audio processing capabilities including equalization, adjustable noise
reduction settings, custom microphone panning, gain sharing automixer, and dynamics
processing to improve the in-room and far-end room audio experience
To add a SoundStructure system to an ATX system, first follow the ATX system Integrator's guide and
configure the HDX 8000 codecs using the standard configuration tool [2]. Once the ATX system has
been configured, then follow these steps.
1. Unplug the Polycom microphone arrays and the audio amplifier from the primary HDX 8000
codec
2. Connect the SoundStructure device to the primary HDX 8000 codec
3. Connect the audio amplifier to the SoundStructure device
4. Connect the Polycom microphone arrays to the SoundStructure device
5. Modify the example SoundStructure configuration file as necessary
6. Upload the configuration file to the SoundStructure system
These steps are described in detail in the remainder of this application note.
While any SoundStructure C-series device or system of SoundStructure C-series devices may be added
to the ATX system, depending on the number of audio channels required, this application note and the
resulting SoundStructure configuration files are based on a single SoundStructure C16 device. The
solution presented in this application note also includes an optional ceiling-fill loudspeaker zone to
improve the audio experience in larger rooms.
Supported Software Versions
This application note was tested with the HDX video codecs running firmware version 3.0.1 or later. The
SoundStructure device is running firmware v1.3.3 or later and SoundStructure Studio version should be
v1.5.0 or later.
When the SoundStructure system is integrated with the ATX system, video calls connecting with Cisco
Telepresence Interoperability Protocol (TIP) mode is not supported.
