Note: I'm unaffiliated with Goldhorn, just an owner of one of their DSP amplifiers (the DSPA 816PRO). In the instructions/videos provided by Goldhorn, I could not find enough information to properly set up SKYATOM surround processing. This video shows what I've discovered on my own, and I hope it helps others!
If there's a demand for it, I can show more details of the Goldhorn DSP and how to best optimize your system with it.
