Tuning Snapshots
Tuning Snapshot stores all the values of the current setting. A maximum of 5
Snapshots can be stored. When clicking on Tuning Snapshots, the Tuning History
Navigator is opened. Tuning History Navigator saves the history of the tuning changes
with each node corresponding to a single tune setting changed from the previous
node. More information about Tuning History Navigator and Tuning Snapshots is found
in the PPC3 User Manual.
I²C Monitor
Use the I²C Monitor to execute direct read and write commands to the device and
view the I²C transactions happening as a result of device operation performed using
the PPC3 application.

available in the Home window of the application. Access the I²C Monitor by clicking
the I²C Monitor icon in the bottom bar, in any of the pages.
Equalizer
The Equalizer window allows the configuration and setting of the different Biquads available in the audio
processing of the device. By default, all the equalizers are turned off in the stereo device, while for the
mono device, a 120-Hz low pass filter is implemented by default with EQ1.
Figure 6. Equalizer Window
Different equalizer types can be implemented and all the changes to them are reflected in the different
plots. Composite plot (red) reflects the sum response of all the equalizers configured. The details of
each equalizer setting (as filter type, frequency, gain, and phase) is found in the bottom of the chart
section. Each equalizer is turned on or off independently and offer the option of reading or writing the
BQ coefficients directly by clicking in the turn (
) icon. The setting of the equalizers is ganged for left
and right channels by default, but can be configured independently by the user when de-selecting
“Ganged” box.
Phase , Group Delay , Impulse Response , and pole/zero charts are available as well for
the analysis of the equalizer response.
