PC Software Design Many of the products developed by Indesign, LLC include a Digital Signal Processor (DSP). For fast and efficient processing of audio, video and other math intensive signal processing a DSP is the best device for the application. DSP applications are usually programmed in the same languages as other science and engineering tasks, such as: C, BASIC and assembly. The power and versatility of C makes it the language of choice for computer scientists and other professional programmers.

Before downloading and installing the DM Smart DSP software you need to power up your DM processor or Matrix DSP amplifier and connect it to your computer via the included USB cable.

Then you will need to download the software from the bottom of the DM-810 product page here, or from the DM-608 page here, or from the D 6.1200 page here, or from the D 4.800 page here.

After downloading, open the DM Smart DSP Zip folder, it should be in your Downloads folder:

Then double click on the DM Smart DSP application file to start the install:

If you get the “Windows protected your PC” pop up select More Info and Run Anyway.

The setup wizard will start up, click Next for the first 3 windows that pop up:

Select Destination Location:

Select Start Menu Folder:

Select Additional Tasks:

Ready To Install – Click Install. The software installation will start.

When the installation is complete you should see the “Completing DM Smart DSP Setup Wizard” screen.

Check the box: Launch DM Smart DSP and click Finish.

The software will launch and check to see if the DM processor or DSP amp has the latest firmware, if an update is available you will be prompted to update the firmware, follow the prompts to complete the update.

Ground Zero Dsp Software

You may also see a window indicating that the drivers need to be updated. Click OK and follow the prompts for Device Driver Installation:

The final prompt will be to enter the default password which is 1234
