Saving Presets - Polycom SoundStructure C16 Design Manual

then looks for the power on preset. If the power on preset is found, the system boots to the power on preset.
If the power on preset is not found, any current settings that may have been stored in the configuration file
is restored. If the current settings are not found, then the factory default settings are used. Note that the
factory default settings are not necessarily be useful as matrix cross points are muted by default and gains
are set to 0dB.
Preset Names
When presets are stored, the preset name may be customized to any arbitrary string of up to 256 bytes in
length. When naming presets, keep in mind the preset name is used in the command syntax to invoke the
execution of the preset. It is recommended that a preset name be descriptive to aid in selecting presets for
execution from within SoundStructure Studio. As described later in this chapter, presets are executed with
the run command with the preset name as an argument.
Number Of Presets
The number of presets is limited only by the amount of available non-volatile memory in the SoundStructure
system. For single device installations, it is estimated that more than 100 full presets may be stored in the
device.

Saving Presets

After the system has been designed with SoundStructure Studio, there is a default full preset called
"Power-On" and the preset is assigned to be the power-on preset. If any changes are made to virtual
channel parameters or matrix cross points are adjusted, the updated settings should be saved in the
"Power-On" preset by selecting the Save Selected preset as shown in the following figure.
When a preset is saved, all the audio settings of the device are compared to their factory default settings,
and only the settings that differ from the default settings are stored in the preset. By comparing presets to
a default set of values, the size of the presets are reduced which allows more presets to be stored in the
device.
Note: Changes to Default Settings Stored in Full Presets
Full presets store the differences from the default settings. If a parameter isn't
shown in a full preset, it is because that value of that parameter is the same as the
default value.
The preset page shows the presets and also the preset contents to make it possible to determine the
settings that are in each preset. The column headings may be selected to sort the preset based on the
