Hypex Electronics Filter Design Release notes

The software package includes:
– Setup + DLL’s for the Hypex Filter Design program v5.0
– Sample impulse files
– FusionAmp firmware v1.51 and v5.7
To use the program extract the HFDSetup.zip file to a local drive and start HFDSetup.exe. After installation is completed, a few sub-folders are created in the same folder as where HFD.exe is installed.
For extra help, please read the “FA Update Tutorial V0200.pdf” which is located in the “Documentation” folder.
The software is designed for use on Windows-7, 8.1, 10 and 11 platforms.
Future software and firmware version will be available at the website, but latest FusionAmp firmware (v1.51 and v5.7) are also included in this HFD update in the “FusionAmp fimware” folder.
Please note that v1.51 is intended for FusionAmps currently running v1.3x or v1.4x, and v5.7 can only be installed on FusionAmps currently running v5.x
Also note that v5.x FusionAmps can only connect to this HFD version v4.98 or newer For sample impulse files, please see folder ‘Sample files’ (it also contains a file with flat response data).
Starting with HFD version 4.9, a connected FusionAmp should have firmware version v1.4 (or higher). Please update your FusionAmp to version 1.51 (see folder “FusionAmp firmware”).
Note: if your FusionAmp currently has a firmware version 1.3x or lower, please start with updating your FusionAmp to a v1.4x (like 1.44 or 1.46), before installing v1.51
Note2: Please notice that only firmware v5.x+ has FIR capability, due to a hardware change
