Preset Operation - Polycom SoundStructure C16 Design Manual

Note: Analog Outputs Muted During Full Preset Execution
The analog outputs of the SoundStructure system are muted during the time it takes
to execute a full preset.
Partial Presets
Partial presets store only the settings that a user places into the partial preset. Partial presets are designed
for use with volume control applications and muting multiple signals and any other applications where it is
necessary to run multiple commands with a single API command. Any parameter within SoundStructure
may be adjusted with a partial preset. Partial presets are similar to the concept of macros in the Polycom
Vortex products.
When partial presets are executed, the commands in the partial presets are executed sequentially with the
first command listed executing first.

Preset Operation

SoundStructure devices store presets in non-volatile memory to ensure the preset settings are not lost upon
power cycling. When presets are executed, all the parameter settings for the preset are copied into the
current device settings which are stored in RAM and become the parameters the device operates from. Any
adjustments to the device settings, such as volume adjustments or muting, make adjustments to the
RAM-based current settings of the device. When the current settings are saved to a preset, the current
settings are stored to the non-volatile memory with a default preset name. The preset name may be
customized as described next.
Unless the current settings are copied to a preset using the Preset Save function, the current settings are
be lost upon power cycling. Using SoundStructure Studio, current settings of the device can be saved to full
presets and restored from full presets as shown in the following figure.

Power-On Full Preset
SoundStructure full presets operate in a similar fashion to Polycom's Vortex products where there is a
"power on" preset that must be selected for the design when the device powers up. When creating a new
design, the last step of the SoundStructure design process saves the settings to a preset called "Power-On"
and sets the power on preset to that preset.
When a SoundStructure device boots up, it reads its internal configuration file and defines its virtual
channels and virtual channel groups, sets the system default values for these channels and groups, and
