Design Guide for the Polycom SoundStructure C16, C12, C8, and SR12
6 - 16
Because microphone arrays may be shipped with a firmware version that may
be earlier than version 24, the firmware should be updated once to revision 24
by connecting the microphones directly to the right CLink2 port (the port clos-
est to the OBAM interface) on SoundStructure device for 30 seconds.
Detecting CLink2 Devices
When connected to a SoundStructure device, the wiring page shows the status
of the number and type of CLink2 devices. This information is shown in the
following figure where four table mics and one HDX video codec were discov-
ered. To have this information automatically updated as devices are connected
over CLink2, select the poll device information check box on the top of the
wiring page.
Digital Microphone Array Example
As an example of using the digital microphone arrays, consider a design that
uses two ceiling microphone arrays, one wireless analog microphone, a stereo
program audio source, a Polycom HDX video conferencing system, a tele-
phone line, and a stereo amplifier.
To make sure the firmware on the microphone arrays is compatible with the
SoundStructure device, during the installation process plug the microphone chain
(up to four microphones may be cascaded during this process) into the right CLink2
port of SoundStructure for 30 seconds to ensure the firmware is updated to the
version required for SoundStructure operation.
This process only needs to be done once, even if the microphones will ultimately be
connected directly into the HDX and not the SoundStructure device.
