POWERSOFT PRESETS
On the evaluation version of D-CELL504DSP-IS the same basic preset is stored in all four memory locations of the DSP.
The following figure shows the corresponding project of SigmaStudio:
The content of the first block (
Input Adder
) is the following:
As you can see, it’s only an adder with a linear gain, and its function is to gain 3dB of SNR without changing the level of the
resulting signal.
At the end of the path there are the four DACs available on the DSP: the corresponding blocks (
DAC CHx with limiter
)
contain a compressor which parameters have been set so that it acts as a limiter that prevent the saturation of the DAC:
we
recommend to always use this block at the end of the path
.
To load the DAC limiter block in your own project, do the following operation:
Drag a “Hierarchy Board” from the Schematic Design group in the
TreeToolBox (or, that is the same, from the System group in the
ToolBox) into the Schematic area.
Right-click on the block just created and choose File/Load Board from
the contextual menu.
Select the “POWERSOFT_DAC_limiter_block.dspbrd” file* and open it.
*The “POWERSOFT_DAC_limiter_block.dspbrd” file is included in the “Powersoft_D-Cell_Package.zip” downloadable from
the Download/Modules/ section of Powersoft’s website:

In this package you will find other examples of presets designed for different configurations: Subwoofer, 2-way speakers,
Sub 2 Satellites systems, etc..
