RealPresence® Group Series Video System Compatibility with
SoundStructure System Firmware and SoundStructure Studio
The current release of SoundStructure System Firmware and SoundStructure Studio are
compatible with the RealPresence Group Series video systems. However, in the current
release of SoundStructure firmware and Studio only HDX systems components and audio
routing are identified in the user interface.
To use SoundStructure with RealPresence Group series products, users can simply select
the equivalent ‘HDX’ option for the system component or audio routing that is being
configured for integration with Group Series products.
The next release of SoundStructure firmware and Studio will be updated so that the
system component and audio routing descriptions address both HDX and RealPresence
Group Series products.

In addition to the firmware file, a sha1sum checksum of the firmware file may also be
downloaded to verify the firmware file has been properly downloaded and matches the file
on the web site. The contents of this checksum file are shown below.
5ebc76319bf97e5a662966041d267fec106cd685 firmware-1.6.1.bin
Bug Fixes
[SERF-371] Fixed an issue in the flash memory driver that could result in the device
becoming unresponsive until rebooted. This condition could be triggered by repeated
running of presets in a specific order with a specific configuration loaded into a device. The
effect of the bug was to cause a software failure on SoundStructure resulting in the front
panel LED changing to solid yellow, an error message in the log (typically about “address
not mapped to object”), and the device would become undiscoverable, unresponsive via
RS232 or Ethernet, and would require a reboot.
[SERF-628] Fixed an issue in the flash memory driver that could cause systems running in
elevated temperature operating environments(> 40 °C ambient) to fail to successfully
reboot when power-cycled. If this happened, the devices would have their front panel LED
flashing green, and SoundStructure Studio would be unable to discover or control the
device. If a device was in this state, it required the user to power the device off, allow it to
cool into a valid temperature operating range, and then power it back on.
[SERH-23] Fixed an issue that could cause a SoundStructure device to fail to successfully
re-boot after executing a sys_reboot command. This issue only affects customers who are
routinely using the sys_reboot command. The symptom of this bug is that after issuing a
sys_reboot command, the device’s front panel LED will remain in the flashing green state
and never change to solid green. In this state, the device cannot be discovered or
controlled by SoundStructure Studio, and requires a manual power-cycle to recover.

SoundStructure Studio 1.8.0 Release Notes
April 27, 2012
SoundStructure Studio version 1.8.0 is a release that includes support for Ethernet
Authentication. Detailed information about the Authentication feature, new API commands
and parameters are described in the SoundStructure Authentication Chapter of the
SoundStructure Design Guide (Revision G, Chapter 12).
New Features
Authentication
The Authentication feature has been added to SoundStructure Studio 1.8.0 and
companion SoundStructure Firmware 1.6.0. Use of the Authentication is optional, and
the default system shipping configuration has Authentication disabled. A new
Authentication dialog is available in SoundStructure Studio; it allows for enabling
Authentication and setting the password, as shown in red box in the figure below.
Copyright © 2008-2013 Polycom Inc.
Page 2
Polycom SoundStructure Release Notes
Authentication may be enabled via SoundStructure Studio without specifying a
password and in those cases the password will be the default ‘456’.
Authentication available for network access, but not direct connection to RS-232
port
When Authentication is enabled a login is required to access the SoundStructure
system over the network, however you may always access the system via the RS-232
port without logging in. The RS-232 port on an Authentication enabled system can be
used for third party control systems without logging in with a password.
Authentication Feature Enablement
Authentication can only be enabled for the Ethernet connection to the SoundStructure
system. Login credentials are entered and stored on the device separate from the
configuration file. This means that configuration files can be shared among multiple
devices without sharing or revealing login credentials.
Authentication feature supports a single level of authorization
An authenticated user has ‘Admin’ authorization, there are no other types/levels of user
access
Authenticated Systems use port 52775
SoundStructure systems with Authentication enabled use port 52775 for access over
network, unauthenticated systems use port 52774. This means that SoundStructure
Studio versions prior to 1.8 cannot discover a system that has Authentication enabled.
Copyright © 2008-2013 Polycom Inc.
Page 3
Polycom SoundStructure Release Notes
When Authentication is enabled, any third party control systems that are connected
over a network will lose their connection on port 52774 and must reconnect on port
52775.
Password/Login Credentials Transmission
Transmitted in clear text (no encryption) via online connection to SoundStructure.
Password can be any string of characters and digits, 128 characters or less, no
minimum.
SoundStructure Device Discovery
The computer running Studio must be on the same subnet as the SoundStructure
system for automatic system discovery. SoundStructure Studio can discover
SoundStructure Systems as with previous versions by using: “Menu: Connect> Search
for Devices”. Authentication enabled systems are identified with a ‘Key’ symbol as
shown in the figure below.
Version Checking (SoundStructure Studio 1.7)
SoundStructure Studio version 1.7 introduced a version checking feature that does not
allow files saved with a newer version of SoundStructure Studio to be opened by older
versions of SoundStructure Studio. Thus, configuration files saved in SoundStructure
Studio 1.8 cannot be opened in Studio 1.7. This feature avoids the loss of configuration
file details associated with new features when opened with a version of Studio that
does not support the features. Versions of Studio prior to 1.7 do not support version
checking and thus are vulnerable to loss of configuration file details if opening files
saved by later versions of Studio.

Polycom SoundStructure Release Notes
Bug Fixes
[IVBS-817]Fixed an issue where a VoIP call transferred to another party which rejected the
call, the ‘End Call’ soft key was not visible.
[IVBS-819] Fixed an issue where a SoundStructure VoIP call to conference bridge
displayed the wrong soft keys when a ‘Blind Transfer’ was initiated. Now shows ‘Resume’,
‘New call’, ‘Transfer’ and ‘Conference’ instead of the incorrect soft keys ‘Send’ and
‘Cancel’.
Feature Implementations and Known Limitations
[IVBS-857] There is a known limitation in SoundStructure Studio when the number of
channels on the Channels or Logic views exceeds approximately 295 channels. Beyond
channel 295, the mouse events exceed the maximum coordinate space that Windows can
support. A suggested work-around is to group large numbers of channels as channel
groups and expand and collapse them as needed.

Third party control device enablement with Authentication feature
When a control system (or any client) connects to a SoundStructure system that has
Authentication enabled, the control session will start out in the “unauthenticated” state.
In this state, all commands except those on the white-list (see below) will fail with the
error message “authentication required for control.” In order to authenticate the control
session, the control system must send the “authenticate” command with a username of
“admin” and the password that was set when authentication was enabled.
The following table summarizes the Authentication requirements for third party control
systems.

Page 6
Polycom SoundStructure Release Notes
1. Connect to the system over RS-232 and disable authentication. By design, the
RS-232 interface always operates in Open mode
2. Factory Reset device to restore the default open authentication
mode: reset the SoundStructure device and SoundStructure VoIP
Interface by rebooting the SoundStructure device with pins 8 and 9
connected together on the RS-232 interface as shown in the figure.
This will reset the SoundStructure device and SoundStructure VoIP Interface to a
factory fresh state. Approximately five seconds after rebooting the system, the
cable shorting pins 8 and 9 on the RS-232 interface may be removed. The system
will boot up into a factory reset state.
NOTE: Default system password reverts to “456”. VoIP card settings can be
retained by removing the VoIP card prior to reset.
SoundStructure Logs
SoundStructure system logs indicate authentication enabled and authenticate
command. Passwords are displayed as “****” in the log and command
acknowledgements to prevent unintended disclosure
New Commands
API Commands and Parameters
New “Authenticate” API command syntax: authenticate “username” “password”
(Username must be “admin”, password must be ‘system password’ set up in
Authentication mode or default password “456”)
Example default authentication command: authenticate “admin” “456”
System Acknowledgement:
Correct: authenticated
Incorrect username or password response: error “authentication failed”
API Parameters
auth_password
eth_auth_mode
sys_num_auth_connections
Description
•Used to set the password for the system
•Password 128 characters or less
•Password sent as clear text without encryption

+ ‘sys_num_open_connections’
More detailed information on the API parameters is available in the SoundStructure
Design Guide Rev G, Chapter 12, and a complete list of API parameters is included in
Appendix A. Additionally, all API parameters can be viewed in the web interface of the
SoundStructure system.
Bug Fixes
[SERF-609] Fixed an issue where the automixer information was not shared properly
between devices when there were two or more SoundStructure devices linked together.
The effect of this issue was that multiple microphones could be active at the same time for
the same talker if one of the microphones were on the last device, the chairman mode
could fail to operate properly or last mic mode could fail to work properly if the
microphones of interest were on the last device in the system.
[SERF-606] Fixed an issue where the Mute Indication status of HDX Table Mic did not get
updated correctly after executing a power-on preset.
[SERF-604] Fixed an issue that in rare cases caused EQ filters to be applied incorrectly
[SERF-589] Fixed an issue where if a virtual channel group was defined where one or
more of the virtual channel members did not exist it would cause the SoundStructure
device to generate an assertion error and turn the front panel LED yellow until the system
was rebooted.
Feature Implementations and Known Limitations
Polycom Touch Control
Polycom Touch Control software does not currently support the authentication features
introduced with SoundStructure firmware version 1.6.0. If attempting to connect
Polycom Touch Control to a SoundStructure System that has Authentication enabled
an ‘Unable to connect’ error will be displayed on the Touch Control interface as shown

voip_status
Indicates the status LED state on the plug-in card.
voip_transfer
Used to transfer a call.
voip_uc_sw_ver
Gets the VoIP Interface UC Software version.
New Behaviors for run command and phone_connect and phone_dial parameters
This version of software adds an immediate API acknowledgment run “Preset Name”
where Preset Name is the name of the preset to be executed. As an example, when a
control system executes a command to run a preset as shown next, the system will
respond with an immediate run acknowledgment and then after the preset has finished
executing, the system will respond with the standard ran preset acknowledgment.
run “Preset Name”
run “Preset Name”
…
ran “Preset Name”
This new run acknowledgment provides immediate feedback that a preset execution
has begun. Once the preset has finished executing, the ‘ran “Preset Name”’
acknowledgement is generated like with previous versions of firmware. The new run
acknowledgment allows a control system programmer to indicate to the user that a
preset is running. For example, the control system programmer could disable the
preset button until the preset ran acknowledgment has been received to prevent the
user from executing the preset multiple times due to the previous absence of visual
feedback.
Added new functionality to the phone_dial and phone_connect commands where a
telephony interface (analog TEL1 or TEL2 or the VoIP Interface) will be dialed if the
phone is taken off-hook within 20 seconds of dialing digits. After 20 seconds, the digits
will be discarded. In previous versions of SoundStructure firmware, if digits were dialed
with the phone_dial command before the phone was taken off-hook, the digits were
discarded.
Finally, the parameter pstn_dtmf_tone_duration has been added to presets to allow
changing the default length of the DTMF tone duration (100msec) for analog telephony
interfaces (TEL1 and TEL2) and have those settings stored permanently in the
SoundStructure device. Because there is no SoundStructure Studio UI to adjust this
value, you will need to set the value manually from the SoundStructure Studio data
console. To do this, open the console by right clicking on the project name and select
console as shown in the following figure.

Polycom SoundStructure Release Notes
Once the console is open, type in the command below and press send as shown in the
following figure.
set pstn_dtmf_tone_duration “Phone Out” 300
The system will respond with the acknowledgment below
val pstn_dtmf_tone_duration “Phone Out” 300
as shown in the following figure of the console window. To make this change survive a
power cycle, save the settings to the power-on preset.

Yellow Front Panel Light Behavior
This version of software changes the SoundStructure system behavior when there is a
mismatch between the configuration file and the type or number of plug-in cards
installed in a system. With previous firmware versions, any mismatch between the
telephony cards installed in the system and the telephony cards specified in the
configuration file would cause the system to have a yellow front panel LED and the
system would appear to have an empty configuration file and consequently would not
pass audio.
With the new behavior, a SoundStructure system that has a mismatch between a plugin card and a configuration file will continue to run the existing configuration file and
pass audio but will not be able to use any of the plug-in card resources. To indicate
this condition, the front panel LED will still be yellow when there is a mismatch between
plug-in cards and the configuration file.
When connecting to the system with SoundStructure Studio to get the configuration file,
the Upgrade Plug-in tool will launch automatically to allow the user to correct the
telephony plug-in card mismatch.
Factory Reset
Added the ability to factory reset the SoundStructure device and a
SoundStructure VoIP Interface by rebooting the SoundStructure device
with pins 8 and 9 connected together on the RS-232 interface as
shown in the figure. This will reset the SoundStructure device and
SoundStructure VoIP Interface to a factory fresh state. Approximately five seconds
after rebooting the system, the cable shorting pins 8 and 9 on the RS-232 interface
may be removed. The system will boot up into a factory reset state.
Muted Microphones, NOM, and Gating Indicators in the Automixer
This version of firmware changes the behavior of the automixer so that a microphone
that is muted at the SoundStructure input (using the mute parameter) will no longer
count against the Number of Open Microphones (NOM) limit. This means that if the
automixer NOM is set to 1, a muted microphone will no longer prevent a different talker
from gating on a different microphone while the original talker is still speaking into their
muted microphone. In addition, a microphone with a local talker speaking into the
microphone will no longer appear to be gated when the microphone is muted.
Remaining consistent with previous versions of firmware, if a local talker is speaking
into a muted microphone, the automixer will not gate on a different microphone that
may also be picking up the local talker. This automixer feature, included in the initial
release of SoundStructure firmware, enables private side-bar conversations where a
local talker can mute their microphone and not have a different microphone gate on
and transmit their side-bar conversation. This assumes that the local muted
microphone is the microphone that would normally gate on if the microphone were
unmuted.

SoundStructure Studio 1.7.0 Release Notes
November 30, 2011
SoundStructure Studio version 1.7.0 is a release that includes support for the
SoundStructure VoIP Interface.
New Features
SoundStructure VoIP Interface Support
Added support for designing projects with the SoundStructure VoIP Interface. Similar
to the analog telephony channels the SoundStructure VoIP Interface is represented by
an input virtual channel and an output virtual channel and has physical channel types of
voip_in and voip_out, respectively.
Added the ability to set the network settings of the VoIP Interface from SoundStructure
Studio and added VoIP status information to the SoundStructure Studio wiring page.
See the updated SoundStructure Design Guide (revision F), Chapter 12 for detailed
information on how to design a project with the SoundStructure VoIP Interface. The
design guide is available under the Help menu within SoundStructure Studio.
Phone Settings Page
Updated the Phone Settings dialog on the Channels page to emulate a Polycom
SoundPoint IP desktop phone for dialing new calls, placing calls on hold, transferring
calls, and conferencing. Up to 12 line registrations can be configured and shown on
the Phone Settings page. The Phone Settings user interface can aid in learning to use
the new VoIP API commands by opening the SoundStructure Studio data console and
observing the output as the interface is used.
Upgrade Plug-in Card Tool
Added an Upgrade Plug-in card tool that simplifies transitioning a SoundStructure
project with TEL1 or TEL2 plug-in cards to a SoundStructure VoIP Interface. The
Upgrade Plug-in card tool supports changing from any set of SoundStructure plug-in
cards to any different set of plug-in cards. See the SoundStructure VoIP Interface

chapter of the SoundStructure Design Guide for information on how to use the Upgrade
Plug-in Card tool. The Upgrade Plug-in card tool may be accessed from the Tools
menu or from the Wiring page.
The upgrade plug-in card tool is also automatically used when connecting to a system
that has a yellow front panel light due to a plug-in card mismatch with the configuration
file and will convert the project to match the underlying installed hardware.
Preset Run Status
Added a status update on the lower left of the SoundStructure Studio page to indicate
when a preset is running. This corresponds to the new preset command
acknowledgment of run <Preset Name> that indicates that a preset execution has been
initiated. Once the preset finishes executing, as indicated by the ran <Preset Name>
acknowledgment, the preset indicator on SoundStructure Studio is no longer displayed.

10. SoundStructure Studio 1.5.0 Release Notes
January 20, 2011
SoundStructure Studio version 1.5.0 is a release that includes support for using the
Polycom Touch Control with a SoundStructure system.
New Features

Added support for up to four Polycom Touch Control devices to be added to a
SoundStructure project to be used as a controller for SoundStructure audio
conferencing applications. The Polycom Touch Control can be ‘paired’ with either a
Polycom HDX system, or with a SoundStructure system. Only one Polycom Touch
Control needs to be added to a SoundStructure Studio project to support pairing
with multiple Polycom Touch Controls with a SoundStructure system.
See the SoundStructure Design Guide (revision E), Chapter 11 for detailed
information on how to design a project with a Polycom Touch Control and how to
integrate the Polycom Touch Control with the SoundStructure System.
See the User’s Guide for the Polycom SoundStructure Systems and the Polycom
Touch Control Device for detailed information on how an end-user will interact with
the Polycom Touch Control to control a SoundStructure system.



Changed the UI display for digital_gpio_held on the events page to show true/false
rather than open/closed.
Changed the ‘red’ status LED range on SoundStructure Studio’s wiring page for
phantom power voltages to only illuminate red when the phantom power is less than
44V. Any voltage value of 44V and above is a valid phantom power voltage
reading.
Changed the UI for the Signal Generator on the wiring page to show only one virtual
channel associated with the first device in a system. As with previous versions, only
one signal generator may be part of a system and now the wiring page properly
reflects that.
Bug Fixes

Fixed an issue where SoundStructure Studio would close unexpectedly when
editing an event that used phone_flash or phone_redial.

Fixed an issue where SoundStructure Studio could not show the logic input or
output array status properly on the logic page if the array value was larger than
9999

Fixed an issue where the system could add only the ‘in’ channel of the headset
interface adapter if there were no available output channels.


Fixed an issue where selecting a filter from the EQ page for a virtual channel group
would enable the EQ filters for all the channels in the virtual channel group,
regardless of whether the EQ filters were previously enabled for a particular virtual
channel. This could result with a virtual channel having more filters enabled than
required with the additional filters operating with a flat frequency response.
11. SoundStructure Studio 1.4.1 Release Notes
October 29, 2010
SoundStructure Studio version 1.4.1 is a maintenance release that improves the usability

TEL1 card could cause SoundStructure Studio to terminate unexpectedly.

Fixed an issue where it was required to save an online project prior to being able to
execute a preset when the Run button was pressed if virtual channel names or
virtual group names had been changed since the last time the project was saved.

Fixed numerous issues that could cause SoundStructure Studio to close
unexpectedly while using the preset recorder, events editor, channels, and matrix
pages.

Fixed an issue where SoundStructure Studio could not create a logic array with
more than 27 pins.

Bug Fixes

Fixed an issue where querying the state of an empty virtual channel group (e.g., get
mute “Mics” when “Mics” is a virtual channel group with no members) would cause
an assertion that would turn the master SoundStructure device’s front panel light
yellow and cause the system to stop responding to both API commands and
SoundStructure Studio until the system was rebooted.

Fixed an issue where it was not possible to enable the AMX beacon without causing
the SoundStructure device’s firmware to become unresponsive.

Fixed an issue where log messages were not formatted properly for command

Fixed several issues with logic arrays including allowing more than 27 pins to be
defined, and properly mapping the event action when large logic arrays are used.
13. SoundStructure Studio 1.4.0 Release Notes
May 24, 2010
SoundStructure Studio 1.4.0 is a major release adding a partial preset recorder capability
and support for the Polycom Headset Interface adapter.
SoundStructure Studio version 1.4.0 is recommended for use with all SoundStructure
designs regardless of the target firmware of SoundStructure devices. There is no
minimum firmware version required to take advantage of the features within
SoundStructure Studio 1.4.0.
New Features
The new features of SoundStructure Studio version 1.4.0 are introduced below. For
detailed information on using the new SoundStructure Studio, see the SoundStructure
Studio 1.4 primer document that is available on the Polycom website.
Preset recorder
SoundStructure Studio 1.4 includes a preset recorder that allows one to create partial
presets simply by starting the recorder and then using SoundStructure Studio’s user
interface to change the project settings. The results can be stored to a new partial
preset or appended to an existing partial preset.
Headset interface adapter support
The Polycom Headset Interface adapter, 2200-33206-001, has been added as an
input/output option within SoundStructure Studio and can be easily added to a project
and with all the SoundStructure Studio settings set appropriately.

Polycom SoundStructure Release Notes
Auto Route Option
Added the option to not auto-route signals in the matrix when adding channels and
creating projects. This option will retain its value between SoundStructure Studio
sessions.
Command line argument
Added support for the command line argument, -connect, to automatically connect to a
system when Studio is launched. The connect option can accept an IP address or a
serial port.
Automatically Generated Event Names
Automatically created events names now begin with an underscore, “_”, to differentiate
the automatically created events from user defined events.
Event Copy Button
Added an event copy button on the Events page to simplify creation of new events. An
event can be copied by selecting the event and clicking the event copy button.
Improved wiring report
Wiring report includes physical logic pin connection information.
Bug Fixes

Fixed some UI issues where sorting events could cause the event under the mouse
to have a white background and white font.

Fixed an issue where renaming a stereo channel via the Edit Channels dialog did
not update the wiring page correctly.

Fixed an issue where MAC addresses were not sorted properly in the Connect to
Devices control.

Fixed an issue where if the SoundStation VTX1000 was the only remote audio
source, the SR12 would be selected by default.

Fixed several assertion errors that would cause SoundStructure Studio to close
unexpectedly.

Fixed an issue where removing a command from a full preset created a partial
preset that would mute the system during execution and unmute when finished
executing.

Fixed an issue where after using the project conversion wizard the number of
unused inputs for an SR12 was not calculated correctly.

SoundStructure Studio now allows logic outputs to be used as event sources.

Bug Fixes

Fixed the following issue with SoundStructure systems that have two or more
SoundStructure devices running version 1.3.0 or 1.3.1 firmware. In some cases
after a large configuration file upload, or in rare cases after a preset execution,
some parameters in the SoundStructure system could still have their default values
(e.g., muted crosspoints or safety muted) even though SoundStructure Studio
displayed the desired settings (e.g., unmuted crosspoints and not safety muted).

Changed the behavior of the loop drop auto-hangup function to auto-hangup even if
there is no phone line plugged into a telephony card.
15. SoundStructure firmware 1.3.1 Release Notes
January 27, 2010
SoundStructure firmware 1.3.1 is a patch release that corrects a difference in how virtual
channel group acknowledgments are generated compared to earlier firmware versions.
In addition to the firmware file, a sha1sum checksum of the firmware file may also be
downloaded to verify the firmware file has been properly downloaded and matches the file
on the web site. The contents of this checksum file are shown below.
bfb1a41d51eb9cf474639fc76c04aff49718be2a firmware-1.3.1.bin
Bug Fix
In version 1.3.0 firmware, acknowledgements from virtual channel group commands are
not sent to secondary control connections. For example, if SoundStructure Studio were
used to mute a virtual channel group, a control system also connected to the
SoundStructure system would receive the proper mute acknowledgment for the individual
channels in the group but would not receive the mute acknowledgment for the group
name.
In addition, if a virtual channel group were used in a preset, or in the action of an Event,
correct command acknowledgments would be generated for the individual channels in the
group, but not for the group name.
This virtual channel group acknowledgment behavior difference could affect the status of a
control touch panel display if the control system is expecting the acknowledgment from the
virtual channel group name.
16. SoundStructure Studio 1.3.0 Release Notes
December 15, 2009
SoundStructure Studio 1.3.0 is a major release adding new Events and logic input/output
functionality to support the SoundStructure 1.3.0 firmware release (See Section 17 for
SoundStructure 1.3.0 firmware details).
Copyright © 2008-2013 Polycom Inc.
Page 23
Polycom SoundStructure Release Notes
It is recommended to use SoundStructure Studio version 1.3.0 for all SoundStructure
project designs regardless of the target firmware of SoundStructure devices.
New Features
The new features of SoundStructure Studio version 1.3.0 are introduced below. For
detailed information on using the new SoundStructure Studio and firmware 1.3.0 features,
see Chapter 9 in the revision D, or later, SoundStructure Design Guide. The
SoundStructure Design Guide may be found from the help menu in the version 1.3
SoundStructure Studio software.
Events
SoundStructure Studio version 1.3.0 introduces the Events page for creating and
editing events. Events are a very flexible way to cause specified actions to occur
based on a source and a trigger and are used to connect logic input pins to control
settings within SoundStructure such as executing presets based on logic pin changes,
or muting microphones based on a button push. Events are also used to integrate the
HDX IR remote controller with a SoundStructure device, allowing the different key
presses to execute functions within SoundStructure such as taking the PSTN interface
offhook, dialing digits, or muting microphones.
Integrated support for push-to-talk microphones
SoundStructure Studio includes automated support for creating projects with push-totalk microphones through the new logic input mode and logic output mode options
available on the edit channels page. It is possible to add up to 128 push-to-talk
microphones and their associated LED indicators at the same time the microphones
are added to the project. Push-to-talk microphones are supported by SoundStructure
events and all the events are created automatically as the microphones are added to
the project.
HDX/SoundStructure integration uses Events
The SoundStructure integration with HDX no longer requires the names “Mics” and
“Amplifier” as the integration behavior is implemented with Events that may be
customized. These events are added automatically when an HDX video codec is
added to a project. These events allow bi-directional control between a
SoundStructure system and an HDX video codec system. This allows the
SoundStructure system to mute an HDX video codec and have the mute icon displayed
on the video display.
HDX IR remote support added
SoundStructure Studio supports adding an HDX IR remote to a project and
automatically creates the events required to support the different IR key presses.
Configurable Peak Hold Meter
SoundStructure Studio supports different options for the Peak Meter including a One
second peak hold, Peak decay, and Infinite hold until the peak is reset.
Copyright © 2008-2013 Polycom Inc.

Polycom SoundStructure Release Notes
Logic
The new logic page is used for viewing the current status of defined logic input and
output pins, and for changing parameters such as the digital_gpio_hold and
digital_gpio_repeat times and the logic pin names. There is a new Edit Logic interface
for defining digital logic input pins and arrays, digital logic output pins and arrays, and
analog logic input pins.
Last run partial preset
Added last run partial preset to the bottom status bar of SoundStructure Studio.
Windows Vista and Windows 7 Support
Added support for Windows Vista and Windows 7.

detection, then when the phone was taken offhook with SoundStructure Studio, the
last telephone number dialed would be dialed again.
Fixed an issue where some crosspoints were not selectable until a different
crosspoint was selected at which point the first crosspoint could be selected again.
Fixed an issue where selecting two Polycom HDX video codecs for a project would
not fully route the audio between the video codecs.
Fixed an issue where changing the name of a virtual channel group would not
change the original virtual channel group name used in partial presets to the new
name.
Fixed cases where the edit devices wizard would change the wiring of the system
when only the presence of a TEL card was the difference from the designed project
and the target hardware.
Fixed an issue where deleting and rearranging HDX microphones on the wiring
page would cause the microphone green dots indicators on the wiring page to
become unsequenced.
17. SoundStructure firmware 1.3.0 Release Notes

New Features
The new features of SoundStructure firmware version 1.3.0 are introduced below. For
detailed information on using the new SoundStructure Studio and firmware 1.3.0 features,
see Chapter 9 in the revision D, or later, SoundStructure Design Guide. The
SoundStructure Design Guide may be found from the help menu in the version 1.3
SoundStructure Studio software.
Events enable Logic input and output pins and the HDX IR Remote
SoundStructure firmware version 1.3.0 introduces the concepts of Events where events
can be used with logic input pins to execute SoundStructure commands including
executing presets or setting the value of logic output pins.
Added new parameters digital_gpio_held, digital_gpio_hold_time, and
digital_gpio_repeat_time to add more options for using the logic input pins.
The HDX IR remote, with the addition of external IR receiver that connects to the
SoundStructure rear panel, may be used to control SoundStructure devices with
events. Key presses on the IR remote can cause events to execute commands on
SoundStructure allowing full control of a SoundStructure telephony interface.
Zero Configuration Network Support
SoundStructure devices running version 1.3 firmware will default to the link-local IP
address of 169.254.1.1 if the SoundStructure is configured for DHCP and there is no
DHCP server available to provide an IP address when the SoundStructure device
powers up. This makes it possible to connect to a computer directly to a
SoundStructure device with either a straight-through or crossover Ethernet cable
without either having to set a static IP address or having a DHCP server available.
10 New Ring Tones
10 new ring tones have been added to the SoundStructure telephony interface. The
ring tones are selected with the new SoundStructure parameter phone_ring_tone. The
default ring tone is the traditional phone ring tone (phone_ring_tone = 1)
Autohangup based on Call Progress Tones
SoundStructure firmware version 1.3 includes the ability to automatically hang up any
of the SoundStructure PSTN phone interfaces based on the call progress tones of
busy, fast busy, and offhook. There is a new SoundStructure parameter,
pstn_auto_hangup_call_prog_en, that enables or disables this functionality. The
default value is disabled.
Serial port broadcast mode
SoundStructure firmware version 1.3 includes a broadcast mode for the serial port that
allows the SoundStructure device to send commands to other devices. The serial port
may be in one of two modes – command or broadcast. The default mode for the serial
port is command mode. Command mode is compatible with third party control systems
such as AMX and Crestron and allows the SoundStructure system to be fully controlled
or configured. Broadcast mode allows the SoundStructure device to send arbitrary
commands from the selected serial port to control other devices. When in broadcast
mode, any data received on the serial port is ignored.

Polycom SoundStructure Release Notes
Pause the command processor
SoundStructure firmware version 1.3 adds a new parameter, sys_pause, that pauses
the system’s command processor for the specified number of milliseconds. This
means that any commands that are sent to SoundStructure from a control system or
from SoundStructure Studio will be queued up and not executed until the sys_pause
time has passed. The parameter sys_pause can be used to add delays in the
command processing system. For example, to create a one second tone burst, a partial
preset could be created that unmutes the signal generator to an output, pauses for one
second, and then mutes the signal generator
Signal Activity Meter
SoundStructure firmware version 1.3 includes a signal activity meter. This meter can
be used as a source with the events engine. The threshold for the signal activity is set
for all audio channels at once with the signal_activity_thresh parameter.
Version 30 HDX Microphone Firmware
SoundStructure firmware version 1.3 includes the version 30 firmware for the Polycom
HDX microphones. Version 30 firmware makes more efficient usage of the microphone
resources and reduces the power requirement of the HDX microphones. Updating the
SoundStructure firmware to version 1.3 will automatically cause HDX table and ceiling
microphones that are connected to the SoundStructure device to be updated if there is
no HDX video codec connected to the SoundStructure device over conference link.
Current HDX video codec firmware releases include version 30 firmware.
Support for 40 ft OBAM cables
OBAM has been improved to support 1394b Beta cables with lengths of up to 40ft.
Standard high quality 1394b Beta cables may be used with SoundStructure. A 40ft
OBAM cable is now available from Polycom with part number 2200-43229-001.
Faster Preset Execution
The execution speed of both partial presets and full presets has been significantly
improved. Partial presets may be used more efficiently now for volume control,
changing routing settings, and other simple changes to the system. Full presets
execute faster on SoundStructure systems.
Reduced boot time
SoundStructure systems built from either single devices or large multi-device systems
will finish the boot process in under two minutes.
Static IP address improvements
Static IP addresses of SoundStructure devices now remain with the device regardless
of whether a device has been OBAM linked with other devices or has a configuration
file that doesn’t match the hardware (yellow front panel LED state).
Stereo linking for dynamics and AGC
Stereo virtual channels now have the dynamics and AGC processing of both left and
right channels linked together to ensure the stereo image is not affected by gains
applied to the underlying left and right channels.

Polycom SoundStructure Release Notes
Synchronized clink mute state
Using SoundStructure events and the new SoundStructure parameter clink_mute, the
clink mute state can be synchronized across multiple SoundStructure devices that are
linked with OBAM. This ensures that the status LED light on HDX table microphones
are synchronized across multiple SoundStructure devices.
‘online’ RS232 acknowledgment upon power up
When the SoundStructure device has finished booting, the string “online” will be sent
out the serial port interface to indicate the system has finished booting. This can be
used by a control system that is connected over RS232 as an indicator that it can now
send commands to a SoundStructure system.
New API Commands
The following new parameters were added in the SoundStructure firmware version 1.3.
For detailed information about these new parameters, point your browser to the IP
address of a SoundStructure device that is running version 1.3 firmware.
Command
Description
clink call active
Indicates whether there is an active video call
on an HDX connected to the particular
SoundStructure device.
clink local call active
Can be used to indicate whether there is an
active call (HDX video or SoundStructure
PSTN) on a particular SoundStructure device.
When clink_local_call_active is one or greater
on a particular SoundStructure device, the
HDX table microphone LEDs will illuminate
green on that device.
clink mute
Controls the mute state on the conference link
interfaces for the particular SoundStructure
device. Controls the mute state for any HDX
codecs that are connected to that particular
SoundStructure device. When clink_mute is
true for a given SoundStructure device, HDX
table microphones connected to that
SoundStructure device will illuminate red.
clink volume
Controls the volume level on the conference
link interfaces for the particular
SoundStructure devices. This parameter may
be used to map the volume from the HDX to a
fader on SoundStructure.
digital gpio held
Specifies that the particular logic input pin has
been held for the digital_gpio_hold_time in the

Bug Fixes



Removed the limitation where a valid Ethernet gateway address was required
before a local PC on the same subnet could automatically discover a
SoundStructure device using the Connect to Devices feature.
Fixed an issue where the “Amplifier” fader was set to -30 upon power-up in the
version 1.2.5 firmware.
Fixed an issue where the automixer hold time could be set below 100msec. The

18. SoundStructure firmware 1.2.5 Release Notes
October 2, 2009
SoundStructure firmware version 1.2.5 is a maintenance release for improving OBAM
linking performance of large multi-device systems, defined as systems with five or more
devices. This version further increases the capacity of the SoundStructure devices to
synchronize clocks between devices. In previous versions of firmware if a device lost
OBAM link synchronization, the audio outputs on that device could become safety-muted
on that particular device with output signal level shown but no audio heard due to the
safety mute.
When linking multiple SoundStructure devices together for the first time with OBAM, it is
recommended that all SoundStructure devices be updated to the same version of
firmware. In an operational system consisting of multiple SoundStructure devices already
linked together and operating with OBAM, the firmware of all the individual devices will be
updated with one firmware transfer to the system – it is not necessary to unlink an existing
multiple-device system to update firmware. If there is a control system sending commands
to a SoundStructure system, it is recommended that the control system be disconnected
during the firmware update process.
In addition to the firmware file, a sha1sum checksum of the firmware file may also be
downloaded to verify the firmware file has been properly downloaded and matches the file
on the web/ftp site. The contents of this checksum file are shown below.

19. SoundStructure firmware 1.2.4 Release Notes
July 24, 2009
SoundStructure firmware version 1.2.4 is a maintenance release that fixes several issues
and improves the type of data logged and the formatting of the logged data.
When linking multiple SoundStructure devices together for the first time with OBAM, it is

Polycom SoundStructure Release Notes
Log Filters
Version 1.2.4 adds two parameters to the SoundStructure API - sys_cmd_log_en and
sys_mtrreg_log_en. These parameters allow filtering the all command information and
all meter registration and unregistration commands respectively out of the system logs.
sys_cmd_log_en set to 0 will not store any API commands or API acknowledgements
in the log. sys_mtrreg_log_en set to 0 will not store meter registration and
unregistration (mtrreg and mtrunreg) commands in the log. These parameters default
to 1 (on) which was the default behavior of previous firmware revisions.
Log Organization and Format
The organization and format of the logs changed to increase the amount of useful
information that is captured in the logs. The logs now always have sections that have
the original device boot messages, initial power-on preset messages, the current logs
of the device, and detailed system information including temperatures, voltages, and
firmware versions of all SoundStructure devices in a system. The current logs of the
device include the latest information that has been executed. Setting
sys_mtrreg_log_en to 0 will remove all meter registration and unregistration commands
and setting sys_cmd_log_en to 0 will remove all commands and acknowledgements
from the logs so the logs only include system messages.
Bug Fixes

Version 1.2.4 increased the capacity of the SoundStructure devices to synchronize
clocks between devices even when significant clock variances exist between
devices. The result is an improvement in the robustness of OBAM on large multiple
device installs. In previous versions of firmware if a device lost OBAM link
synchronization, the audio outputs on that device could become safety-muted on
that particular device with output signal level shown but no audio heard due to the
safety mute.

Changed the pstn_in_gain parameter to adjust the gain after the line echo canceller
instead of before the line echo canceller. Now as much pstn_in_gain as required
(up to +20dB) may be applied on the telephony input signal without concern for
degrading the performance of line echo canceller. In previous versions of firmware
adding more than +6 or +8 dB of pstn_in_gain could cause the line echo canceller
to sound choppy.

Fixed an issue where executing full presets while the telephone was offhook would
cause the phone to be placed on hook and the call terminated.

Fixed an issue where the SoundStructure cooling fans would occasionally increase
in speed to their fastest rate and then revert back to the speed determined by the
fan speed algorithm.

Fixed an issue where, in rare cases, the automixer on a C8, C12, or SR12 may not
operate properly due to erroneous gating information generated by the device that
prevented microphones from gating on.

Fixed an issue where any non-zero value for the priority attenuation would attenuate
all microphones in the automatic microphone mixer, not just the microphones of
lower priority.
Copyright © 2008-2013 Polycom Inc.
Page 31
Polycom SoundStructure Release Notes

Fixed an issue where a SoundStructure system, in rare cases, could stop
processing commands received from a control system when a significant number of
commands and meter data were being transferred between a SoundStructure
device and a control system. In previous firmware versions, the device would still
be operational and could be pinged over the network, but commands were not
accepted preventing the system from being controlled.

Fixed an issue where after power up of a SoundStructure C16, a tonal noise could,
in rare cases, be present on inputs 15 and 16 and submix 15 and 16 when nonmicrophone inputs are connected to physical inputs 15 and 16. Configurations
where the AEC is enabled on inputs 15 and 16 would never exhibit this issue.
20. SoundStructure Studio 1.2.1 Release Notes
May 18, 2009
SoundStructure Studio version 1.2.1 is an enhancement release that significantly improves
the Edit Devices Wizard functionality, making it more transparent to upload a project
designed for one set of SoundStructure devices to another set of devices. The Edit
Devices Wizard improvements focused on minimizing any wiring changes by preserving
physical channel layout and channel settings as much as possible.
In addition this version fixed UI issues as described in the following sections.
New Features
Edit Devices Wizard
Made significant improvements to the Edit Devices Wizard to minimize any physical
wiring changes when reconfiguring a SoundStructure Studio project from a source set
of SoundStructure devices to a different target set of SoundStructure devices or with
devices that have different telephony interfaces. Also added an option to review the
modified project to review wiring, etc., before uploading the project when the Edit
Devices wizard changes a project.
Windows 64-bit operating system support
Added support for Windows 64-bit operating systems including Microsoft Vista.
IP address change workflow improvements
Improved the workflow for changing the IP address of a system that the user is
connected to over IP. If the IP address is changed, SoundStructure Studio informs the
user it is necessary to reconnect to the system at the new IP address and save the
configuration file to make the new IP address permanent. SoundStructure Studio
automatically disconnects the session and shows the Connect to Devices user
interface once the user hits apply to change the IP address if the user is connected
over the existing IP address.
Firmware update warning over RS-232
Added a warning if a user attempts to update firmware at 9600 bps using the RS-232
interface. Due to the length of time (several hours at 9600 bps) required to transfer the
Copyright © 2008-2013 Polycom Inc.
Page 32
Polycom SoundStructure Release Notes
firmware file over RS-232, it is recommended that higher baud rates be used or, even
better, use the Ethernet interface for firmware updates.
Project save work flow improvements
The file save process checks to see if the current device settings match either the last
saved preset or the last restored preset, and if so the user will not be prompted to save
the settings to a preset. The file save mechanism also has changed to allow a user to
save a project to disk without being forced to save the current settings to a preset if
they didn’t want to change the device settings but did want to save the project to disk.
Keyboard Dialing
Added support for keyboard dialing of digits to the telephony interfaces with the
SoundStructure Studio user interface. If the phone is onhook, any digits dialed are
stored and can be edited by moving the cursor and using the backspace key. Once the
phone is taken offhook, any digits that are present are dialed.
Added support for Israel country selection
Added Israel to the list of supported telephony countries. Israel telephony support to
the SoundStructure firmware was added in the firmware version 1.2.1.
Known Limitations
When running the Edit Devices wizard on a multi-SoundStructure device project that
includes multiple HDX microphones, the resulting project created by the Edit Devices
Wizard should be reviewed before sending the project to the devices to ensure that there
are no more than four HDX microphones per SoundStructure device and that all three
HDX microphones elements from any given HDX microphone are on the same
SoundStructure device. HDX microphones may be manually moved on the wiring page by
clicking and dragging the microphones to a different SoundStructure device.
Bug Fixes

Fixed an issue where HDX microphone elements could be mapped with an invalid
mic_source_index in the configuration file. The effect was, in some cases, an HDX
microphone would be present in the design but would not show any metering
activity on the channels page until the microphone was removed and re-added to
the system again. The effect could also appear as metering from some elements of
one microphone (for example, 3 A) appearing as metering activity for the next
microphone, (for example, 2 C).

Fixed an issue with redrawing signal meter data information on the channels page
where a group of channels could be collapsed and expanded and meter information
not properly redrawn even though audio was present.

Fixed an issue where adding an HDX table microphone could change the
mic_source_type for an existing analog microphone of name “Table Mic”.

Fixed an issue that could cause a program exception during scanning for
SoundStructure devices.

Fixed an issue where Studio would continue refreshing the matrix page when
requested to add more submixes than were available.
Copyright © 2008-2013 Polycom Inc.
Page 33
Polycom SoundStructure Release Notes

Fixed an issue where keyboard up/down key press updates to the fader min or max
caused the fader min/max values to be shown offset form the UI control.

Fixed an issue where changing the reference from a stereo output or submix to
mono output on the “Mics” group caused SoundStructure Studio to show <none> for
the reference.

Fixed an issue where the Edit Devices wizard did not properly update the RS-232
baud rate and IP addresses from the source SoundStructure devices to the target
SoundStructure devices when changing the SoundStructure device configuration to
match a different set of SoundStructure devices.

Fixed an issue where the transfer of a SoundStructure device configuration file
could time-out due to the configuration file taking longer than expected to transfer
and run.

Fixed an issue where the Recent Projects list was not updated to include new
projects that are created and saved.

Fixed an issue where the AEC reference names in the pull down combo box were
not sorted alphabetically. The width of the AEC reference field has also been
updated to expand as necessary to accommodate longer virtual channel names.

Fixed an issue where the names in the Channels and Matrix page were not sorted
properly if the name began with a numeric value instead of an alphabetic character.

Fixed an issue where the matrix fader gain max and input or output signal fader
max were not synced with the firmware if the fader max value was set to 0dB or
lower.

Fixed an issue where setting the first mono AEC reference to <none> forced the
second mono AEC reference to <none>.

Fixed an issue where swapping physical outputs could cause the virtual channels to
lose virtual channel group membership.

Fixed an issue where on some projects the telephony channels did not properly
show the phone setting UI elements. SoundStructure Studio will now correct this
issue if detected in a project file and the corrected settings will be saved when the
user saves the project.

Fixed an issue where changing the name of the signal generator on the channels
page caused a matrix redraw issue that would cause SoundStructure Studio to
prematurely close.
21. SoundStructure firmware 1.2.3 Release Notes
March 17, 2009
Version 1.2.3 firmware is a maintenance release that fixes a rare initialization issue that
could occur on some systems.
In addition to the firmware file, a sha1sum checksum of the firmware file may also be
downloaded. You may optionally use this sha1sum checksum file to verify the firmware file

this checksum file are shown below:
b1cd90534d9af2b93944f52ef4ed69604fdc731a
firmware-1.2.3.bin
Bug Fixes
Fixed an issue when if a SoundStructure device is booted up and there is significant
broadband noise present at microphone inputs, there was the possibility that there could
be a low level audio buzz on some microphone inputs on some devices under the following
conditions: the acoustic echo canceller is enabled, and the non-automixed Snd
Reinforcement ungated signal type is used directly in the matrix without the use of an
automatic microphone mixer.
22. SoundStructure firmware 1.2.2 Release Notes
February 27, 2009
Version 1.2.2 firmware is a maintenance release that fixes several telephony issues and
adds automatic logic input state acknowledgements.
New Features
Logic Input
SoundStructure firmware v1.2.2 includes support for automatically generating logic
input state acknowledgements from analog and digital logic inputs connected to a
SoundStructure device’s logic ports. This means that a logic pin defined with the vcdef
command will automatically generate an API command acknowledgement based on
state changes of the pin.
The following example shows how to define a digital logic input on pin 1 named
“button1”.
vcdef “button1” control digital_gpio_in 1
In this example, when logic input 1 (pin number14) is shorted to ground (pin number
25) the system will automatically generate an acknowledgement of the form
val digital_gpio_state "button1" 0
When the pin transitions to not being shorted to ground, the system will automatically
generate an acknowledgement of the form
val digital_gpio_state "button1" 1
Once the required pins are defined, save the configuration file to ensure the pin
definitions are stored permanently in the SoundStructure file or device. Refer to the
SoundStructure Design Guide found under the Help menu in SoundStructure Studio
(Chapter 3) for additional examples of using the logic pins. Please note in this firmware
release that an external control system is still required to execute SoundStructure
commands for muting, preset changes, etc., based on logic state changes.
Copyright © 2008-2013 Polycom Inc.
Page 35
Polycom SoundStructure Release Notes
In previous releases, the command acknowledgement was not generated automatically
requiring the pin state to be polled continuously by an external control system.
Bug Fixes

Fixed an issue where random aperiodic audio popping could be present on some
audio outputs with certain system configurations.

Fixed an issue where the incoming telephone ring signal was not detected on some
PBX’s and central offices. This issue would prevent SoundStructure from knowing
that the phone was ringing.

Fixed an issue where the phone_ring acknowledgement was using the “Phone Out”
virtual channel name instead of the “Phone In” virtual channel name. This release
and firmware prior to 1.2.0 use the “Phone In” channel name with the phone_ring
acknowledgement.

Fixed an issue where the loop drop auto hangup functionality was not properly
detecting loop drop signaling when the remote party hung up.

Fixed an issue where it was possible to use the ‘ run “PresetName” ’ syntax with
preset names that were not defined. The system will now return an error message
if an invalid preset name is specified.

Fixed an issue with phone_redial where the redial digit buffer could contain more
digits than stored from the last phone onhook usage.
23. SoundStructure firmware 1.2.1 Release Notes
December 19, 2008
Version 1.2.1 firmware is a maintenance release that adds Israel as a valid telephony
country code and also fixes several issues found in version 1.2.0.
New Features
PSTN Support for Israel
SoundStructure firmware includes pstn support for Israel. Because the currently
released version of SoundStructure Studio does not list Israel as a country code option
the country code value for Israel must be set manually via a SoundStructure API
command as follows:
set pstn_country “Phone Out” israel
where “Phone Out” is the name of the telephony output channel. SoundStructure
Studio will show this field as an empty value in the Phone Settings user interface.
Once the setting has been made, save the settings to a preset to ensure they survive a
power cycle.
Bug Fixes

Fixed an issue on any SoundStructure device running 1.2.0 firmware where if an
RS-232 data rate and flow control were set to values other than 9600 bps and none
respectively, the RS-232 data rate and flow control settings would be reset to 9600
bps and none after any full preset was executed.
Copyright © 2008-2013 Polycom Inc.
Page 36
Polycom SoundStructure Release Notes

Fixed an issue on a SoundStructure C16 running 1.2.0 firmware where a stereo
echo canceller reference on input 16 would cause echo to be heard at the remote
site if a microphone was defined on physical input 1 and routed to the remote site
regardless of whether the microphone was physically connected.

Substantially reduced the possibility of occurrence where, after power up of a
SoundStructure C16 running 1.2.0 firmware, a tonal noise is present on inputs 15
and 16 and submix 15 and 16 when non-microphone inputs are connected to
physical inputs 15 and 16. Configurations where the AEC is enabled on inputs 15
and 16 would never exhibit this issue.

Fixed an issue where setting a static IP address on a SoundStructure device
running 1.2.0 firmware on a multi-device system and not connecting a valid Ethernet
connection to that device could, in some cases, cause SoundStructure Studio and
the firmware to become out-of-sync with some parameter values such as matrix
mutes after powering up a SoundStructure device.

Fixed an issue where, in rare cases with eight SoundStructure devices running
1.2.0 firmware, the outputs and inputs on the 8th device may have intermittent pops
on the audio.
Known Limitations

If setting a manual (static) IP address, the gateway value must be configured in
addition to the IP address and subnet in order for the device to be discovered with
SoundStructure Studio. Without a gateway the device can still be manually
connected to by typing in the IP address but it won’t be automatically discovered by
SoundStructure Studio unless there is a valid gateway address.
Using Version 1.2.1 firmware
Review Chapter 7 of the SoundStructure design guide for full information on linking
multiple SoundStructure devices with the OBAM interface.
To update firmware copy the firmware to your desktop or some other easy-to-find location.
Using SoundStructure Studio, connect to the target system and left click on the System
Name in the tree structure in the left pane of SoundStructure Studio. Click the Open
button on the firmware update control to find and select the firmware file and then select
Update to update the firmware for the system. The SoundStructure devices will reboot
after their firmware has been updated.
Multiple device SoundStructure systems that are currently running version 1.2.0 firmware
will have their firmware updated at the same time when the system firmware is updated.
If using firmware earlier than version 1.2.0 and it is desired to link multiple devices
together, update each of the individual SoundStructure devices to version 1.2.1 before
linking multiple SoundStructure devices together. See the firmware upgrade notes
associated with the SoundStructure Firmware 1.2.0 release notes below for additional
information.
24. SoundStructure Studio 1.2.0 Release Notes
November 14, 2008
Copyright © 2008-2013 Polycom Inc.
Page 37
Polycom SoundStructure Release Notes
SoundStructure Studio version 1.2.0 is a release that supports multiple-device linking with
the OBAM interface for up to eight SoundStructure devices.
New Features
OBAM Support
SoundStructure Studio includes OBAM support for designing systems with up to eight
SoundStructure devices and 8 telco cards. The same design process is followed as
building single device systems. In step 3 of the design process the required
SoundStructure devices will be selected automatically based on the inputs and outputs
added to the system. See Chapter 7 of the SoundStructure design guide (available
under the Help menu option) for more detailed information on how to use the OBAM
functionality.
SoundStructure Device Address Book
An address book has been added to the Studio software to make it easy to store fixed
IP addresses of devices to make it easy to connect to the devices. The address book
is stored in an XML file and may be easily shared with other users or kept in a central
location that multiple users can access. Appendix B of the SoundStructure Design
guide includes more information on using the Address book.
Matrix View Enhancements
The virtual channel names may now be changed directly from the matrix page. In
addition the matrix output and input names are frozen on the page to make it easier to
scroll through a large matrix. The Output names and Input name fields may be resized
by clicking and dragging in the space between the virtual channel names and the
faders.
Enhanced Signal Meters
The signal meter display has been enhanced to make it easier to see when the signal
levels reach 0dB. New peak and clip meters have been added. Meter refresh rate has
been increased to improve responsiveness.
Signal meters have been added to the matrix crosspoints and automixer pages.
Convert Project Wizard
A new project conversion wizard makes it possible to take a design for a particular
collection of SoundStructure devices and convert that design to use the devices
discovered during the upload process (when working online) or an arbitrary device
selection (when working offline). When the wizard detects that the target devices don’t
match the devices in the project, it will convert the project devices to match the target
devices and will automatically re-wire the system to fit into the target devices. After the
wizard has run, you should check your wiring to ensure it matches the physical wiring
of the system.
Ethernet Address Confirmation
Added a prompt for the designer when the IP address in the file to be loaded to the
SoundStructure device is different from the IP address that is already associated with
the device. This allows the user/designer to create one configuration file and upload to
Copyright © 2008-2013 Polycom Inc.
Page 38
Polycom SoundStructure Release Notes
multiple SoundStructure systems and use the local IP address in the system rather
than defaulting to the value of the Ethernet address in the configuration file.
Channels Page Scrolling Position
The channels page scroll position is currently saved between page flips to allow the
user to automatically return back to where they were scrolled on the Channels page
before changing to a different page.
Fader Min and Max Controls
Tool tips have been added to the fader min and max controls (the small triangles on the
right of the fader) to make it easier to set the min and max volume controls that can be
used to limit the amount of adjustment on any fader control.
Easier Access to the Phone Settings
A phone onhook/offhook button and dialing buttons have been added to the phone in
channels on the channels page to make it easy take the phone on and offhook.
Recently-Used File List
Added a recently used file menu now to make it easy to find previously designed
projects.
Enhanced File Save
The File Save operation has been improved to ensure that the user is prompted to
store any changes to the last saved or last run preset.
Disconnect from Devices
Added the ability to disconnect from a project and become offline. Right click on the
project name and then select Disconnect to stop communicating with the device. To
reconnect you can send your project to the device or get the project back from the
device.
Instant Designer updates
Added the SoundStation VTX1000 as an analog telephony interface that may be used
with SoundStructure devices.
Improved the Device Information view
Improved the presentation of information on the device information portion of the wiring
page with information of whether the temperature ranges and voltages are within the
expected range (green), are at the edge of the expected range (yellow), or are outside
the expected range (red).
Known Limitations

The meters may briefly flash an erroneous signal level while scrolling on the
channels page.

Selecting a large number of crosspoints in the matrix and changing the crosspoint
gains before receiving all the acknowledgements from a previous change can
create a parameter value update loop which cycles between two or more values
until the edit crosspoint dialog is closed. To avoid this issue, select individual

Polycom SoundStructure Release Notes
crosspoints, small groups of crossoints, or wait for all values to change before
further adjusting the same set of crosspoints.
25. SoundStructure firmware 1.2.0 Release Notes
November 14, 2008
Version 1.2.0 firmware is a release that supports multiple-device linking with the OBAM
interface for up to eight SoundStructure devices and supports the additional features in
SoundStructure Studio 1.2.0.
New Features
OBAM Support
SoundStructure firmware includes support for linking multiple devices together with
OBAM. See Chapter 7 in the SoundStructure Design guide for detailed information on
creating and controlling multiple-device designs.
Bug Fixes

Fixed an issue where the RS-232 port could stop operating if there was too much
data transmitted to the SoundStructure over the RS-232 interface.

HDX8000 and HDX7000 video codecs are shown as properly discovered on the
wiring page. In previous versions these codecs were discovered but not shown as
discovered.

Feedback frequencies are now properly displayed on the feedback
eliminator/equalization page.
Known Limitations

If setting a manual (static) IP address, the gateway value must be configured in
addition to the IP address and subnet in order for the device to be discovered with
SoundStructure Studio. The device can still be manually connected to by typing in
the IP address but it won’t be automatically discovered by SoundStructure Studio
unless there is a valid gateway address.

In rare cases with eight SoundStructure devices the outputs and inputs on the 8th
device may have intermittent pops on the audio.
API Changes
In Version 1.2, the API commands analog_gpio_min and analog_gpio_max have been
removed. The range on the analog_gpio_value parameter has been set to 0 to 255 and is
no longer customizable with the min and max commands.
The dev_led_cycle parameter has been added to make it possible to cycle the LED on the
front panel of the SoundStructure device.
The sys_last_full_preset, sys_last_partial_preset, and sys_last_preset parameters have
been added to make it possible to query which presets were last executed.
Using Version 1.2.0 firmware

Polycom SoundStructure Release Notes
Review Chapter 7 of the SoundStructure design guide for full information on linking
multiple SoundStructure devices with the OBAM interface.
A summary of the required steps is shown below.
1. If the existing firmware in the SoundStructure devices is 1.1.5 or earlier, update the
firmware in each of the SoundStructure devices separately to this version of firmware
before linking devices with the OBAM interface.
If your SoundStructure devices already have an earlier 1.2.0-beta firmware version, all
devices should be able to have their firmware updated at one time. If you experience
any problems while updating firmware for the system when the systems have early
1.2.0-beta software, unlink the OBAM connection between the devices and update the
firmware on the units separately.
To update firmware in your SoundStructure device, copy the firmware to your desktop
or some other easy-to-find location. Using SoundStructure Studio, connect to the
target device and left click on the System Name in the tree structure in the left pane of
SoundStructure Studio. Click the Open button on the firmware update control to find
and select the firmware file and then select Update to update the device. The
SoundStructure devices will reboot after their firmware has been updated.
2. Once firmware has been updated in the individual devices, power down the devices,
connect the OBAM link (OBAM Out on one device to OBAM In on the next device) as
desired to link SoundStructure devices together, and power up the SoundStructure
devices. If the SoundStructure devices were already linked due to having an earlier
version of 1.2 firmware, it is not necessary to power down the devices.
3. Use the SoundStructure Studio 1.2 software to create project files for the
SoundStructure Systems.
A flashing green LED on a SoundStructure device’s front panel indicates that the
device is booting.
A solid green LED on a SoundStructure device’s front panel indicates that the
SoundStructure device has a configuration file that is compatible with the devices the
project is loaded on. A solid yellow LED on a SoundStructure device’s front panel
indicates that the SoundStructure system has not been loaded with a compatible
SoundStructure Studio configuration file. To turn the front panel LED green, upload a
configuration file that has been designed for the target device hardware. For example,
if you have two C16’s linked together, create a project that is designed for two C16s
and upload that project to the SoundStructure devices.

29. SoundStructure firmware 1.1.2 Release Notes
April 4, 2008
Version 1.1.2 is a maintenance release fixing the equalization on outputs and improving
the performance of the digital microphone integration.
Enhancements
SoundStructure firmware 1.1.2 includes an updated Clink2 driver and firmware version 26
for the HDX microphones that improves the device discovery of the HDX microphones.
HDX microphone arrays should be connected to the right rear Clink2 connection on
SoundStructure (closest to the OBAM connectors). Up to 4 microphones may be daisy
chained with up to 4 CLink2 microphones per SoundStructure device (a SoundStructure
C8 supports 2 full HDX microphone arrays).
Installations with HDX microphones will automatically have their microphone firmware
updated to version 26 once the SoundStructure firmware has been updated to firmware
1.1.2. This microphones firmware update process only happens once. This firmware
update may be performed by the SoundStructure device as follows:

Unplug the Clink2 cable between the SoundStructure and the HDX video codec (if
an HDX is used in the system)

Plug the daisy-chained set of digital microphones to the SoundStructure rear right
Clink2 port (closest to the OBAM connectors) for approximately 30 seconds per
microphone (4 microphones would translate to waiting 2 minutes). The microphone
LED will turn amber during the firmware update process.

Once the microphones have been updated, check the Device Information area on
the Wiring page within SoundStructure Studio to verify that all microphones have
been discovered. If not all microphones have been discovered, connect
microphones one at a time to the right rear Clink2 port on SoundStructure to have
their firmware updated and then, once all microphones are updated, reconnect the
daisy-chain.
Bug Fixes

Fixed an issue where the graphic equalization, low shelf, high shelf, and parametric
equalization did not work on line output signals.
Additional Information and Feature Limitations

Polycom SoundStructure Release Notes

Polycom HDX video codec and SoundStructure integration over Conference Link
requires HDX firmware 2.0.1 version or later. Integration with previous versions of
HDX firmware must be done by designing the system and selecting a “VSX8000”
video codec instead of the HDX codec within the SoundStructure Studio software
and using analog inputs and outputs between the SoundStructure device and the
HDX video codec. The internal echo canceller on the video codec should be
manually turned off.

Version 2.0.1 of the HDX firmware has a limitation that only 3 HDX microphones
may be used when an HDX is connected to a SoundStructure over Conference
Link. To support 4 HDX microphones, use version 2.0.2 of the HDX firmware or use
an analog connection between HDX and SoundStructure and connect the
microphones to the SoundStructure device. A SoundStructure C16 or C12 support
up to 4 HDX microphones, a C8 supports up to two HDX microphones.

SoundStructure firmware version 1.1.2 supports single SoundStructure device
systems. Linking of multiple devices via OBAM is not enabled in this firmware
release. As a work-around, in many cases it is possible to send audio from one
SoundStructure to another using analog inputs and outputs of the SoundStructure
devices and ensuring a signal that includes all the remote audio is wired to
subsequent systems and sent to a submix on the additional systems to ensure that
all microphones on subsequent systems have an echo canceller reference that is
set to the submix that includes the remote audio.

Logic input and output ports and the IR port can be defined but require an external
control system to query the status and control the SoundStructure device based on
the query results. See Chapter 3 of the SoundStructure Design manual for more
information.
30. SoundStructure Studio 1.1.1 Release Notes
April 4, 2008
SoundStructure Studio version 1.1.1 is a maintenance release addressing several partial
preset user interface issues.
Bug Fixes

Fixed a bug where copying a partial preset with “Copy to New” created a full preset
rather than a partial preset.

Fixed a bug where using the phone_connect parameter in a partial preset caused
the SoundStructure Studio software to terminate unexpectedly.
31. SoundStructure firmware 1.1.1 Release Notes
February 28, 2008
Firmware version 1.1.1 is a maintenance release fixing an issue where the Line 2
telephony interface on the TEL2 card would not dial DTMF digits.
Enhancements
Copyright © 2008-2013 Polycom Inc.
Page 44
Polycom SoundStructure Release Notes
phone_connect parameter not saved in full presets
Version 1.1.1 no longer stores the phone_connect parameter in full presets. This
means that if a preset is stored while the phone is off-hook, the preset will not store the
off-hook status of the phone. This prevents the situation where the phone would be
forced off-hook when the preset is restored causing dial tone to be heard in the room.
Existing projects with the phone_connect parameter in the preset will have the
phone_connect parameter ignored upon full preset restoration.
Partial presets can still use the phone_connect parameter as desired. For example, a
partial preset could take the phone offhook (set phone_connect to 1) and dial a
telephone number.
Bug Fixes

Fixed an issue where it was not possible to dial telephone calls on Line 2 on a TEL2
interface card. The phone_dial command appeared to work on Line 2 but DTMF
digits were not dialed. Line 1 was not affected.
Additional Information and Feature Limitations
This section lists additional information associated with the release and known limitations.
If a work-around is available, it is listed in the text.

Polycom HDX video codec and SoundStructure integration over Conference Link

not exceed the length limitations of a length from 18in to 100ft to the first
microphone and no longer than 25ft to subsequent microphones up to a total of four
microphones (dependent on the model of SoundStructure) with a total maximum
length not to exceed 175ft.

The SoundStructure SR12 can not be linked to the Polycom HDX video
conferencing system using the Conference Link interface. If it is desired to use the
SR12 as a mixer of different program audio sources and loudspeaker destinations,
connect the SoundStructure SR12 system to the HDX using analog inputs and
outputs.

32. SoundStructure firmware 1.1.0 Release Notes
February 11, 2008
Firmware version 1.1.0 adds support for SoundStructure partial presets, HDX microphone
arrays, the SR12 device, and fixed several bugs.
Enhancements
HDX Microphone Arrays
Added HDX microphone array support and two API commands: mic_source_index and
mic_source_type. These commands are used by SoundStructure Studio to configure
the audio processing to use either the digital microphone array or analog inputs. Each
digital microphone array has three microphones and requires the equivalent processing
of three analog inputs. The mic_source_index and mic_source_type select whether a
digital or traditional analog microphone input use the processing available for the
selected input channel.
HDX microphone arrays should be connected to the right rear Clink2 connection on
SoundStructure (closest to the OBAM connectors). Up to 4 microphones may be daisy
chained with up to 4 CLink2 microphones per SoundStructure device (a
SoundStructure C8 supports 2 full HDX microphone arrays).
When using with an HDX with firmware 2.0.1 and a SoundStructure device, the digital
microphone arrays must have their microphone firmware updated to revision 24. The
microphones firmware update process only needs to happen once. This firmware
update may be performed by the SoundStructure device as follows:

33. SoundStructure Studio 1.1.0 Release Notes
February 22, 2008
Enhancements
Copyright © 2008-2013 Polycom Inc.
Page 48
Polycom SoundStructure Release Notes
Offline Operation and Power-on Preset
Version 1.1.0 changed the behavior of the file open process – once a file is opened, the
power-on preset is executed so that the settings of the preset become the current
settings of the device. This behavior more closely matches the behavior of an online
SoundStructure System that has been powered up.
Limiter on telephony output signals by default
Version 1.1.0 added an output limiter to the telephony output signal that is activated for
signals above -10dBFS and has a compression ratio of 10:1.
Filter Decay is enabled by default
Version 1.1.0 changed the default behavior of the feedback processing by enabling the
feedback filter decay mode by default. The feedback eliminator is not enabled by
default however the ability to have the feedback filters relax automatically is enabled by
default when the feedback eliminator is enabled.
Partial Presets
Added support for partial presets to SoundStructure Studio. Partial presets are lists of
commands that may be executed by running the run command action with the preset
name as the argument. Designers may now build partial presets by selecting
parameters and their arguments from drop down lists.
An example of the command required to execute the partial preset “Volume Increment”
is shown below:
run “Volume Increment”
See Chapter 7 of the SoundStructure Design Guide for additional information.
Offline Device Equipment Changes
Version 1.1.0 added an option on the Wiring page to change the SoundStructure
device selection or to change telephony options. This option allows growing a design
from a smaller SoundStructure device to a larger SoundStructure device, shrinking
larger design to a smaller device (if there are enough unused inputs or outputs), or
adding, removing, or changing telephony cards. Changing the equipment may only be
performed while operating Offline, i.e., not connected to the device.
SoundStructure SR12
Support for the SR12 device has been built into SoundStructure Studio. Audio designs
can be created for SoundStructure SR12’s by not selecting any remote audio sources
such as video conferencing or telephony options.
Polycom HDX Digital Microphone Array
Added support for HDX ceiling microphone and table microphone arrays. HDX
microphones should be connected to the right rear Conference Link port of
SoundStructure. See examples in Chapter 6 of the SoundStructure Design Manual.
