Yes, I have the Pro version.
The subject already reminded me of the allowed usage, which would be not using it for mid/high. So only the replacement of the Hypex would be allowed, hence for Bass only.
A schematic would be useless. Even telling in advance / in theory what to do is quite impossible. Taking out the Hypex would lead to something but it still would be a tedious job.
Something else is that I did not sort out the possibilities of the RME and if it can't bear 10 or so PEQs then it will be useless.
Also, for Bass only, MiniDSP would be sufficient IMO.
