I hope here to find a solution to my problem

Firts of all regarding my setpSetup

Rotel RA 1570
miniDSP SHD Studio with Dirac Live 3.0
B&W 702 S2
Creek Evolution 50CD
Project Phone Box 2
Dual 721 mit AT 33PTG II

The Rotel runs as an ouput stage. It is connected: "Rotel Main In L" <--> Analog Out 2 SHD and "Rotel Main In R" <--> Analog Out 1 SHD. (I hope this is correct?).

The Phonobox is connected to the HD over the analog block, the same for the Creek CD. Last one is also connected over digital to the SHD.

Let's come to the problem I am facing. I had already measured and running everyting since a year., but we moved the furniture and give the room a new style. So I need to repeat te measurement, as the B&W found a new position. So said, I give a try this weekend, but always run into the same error. At the point "Volume Calibration is something wrong. I set the Master Output between 50-80dB (I tried even till max). According to the instruction, I  shall hear a rush, if I click on Dirac 1 play button. That i hear, if the Master Output is at least 60dB. The same rush I shall hear, if I click the Dirac 2 play button, but I hear nothing. Undepended how high or low i place the Master volume or the Mic sensitivity. Additionaly I hear the rush (clicking on Dirac 1) from both speakers and not only from one, like I would expect. Ignoring hat i tried to measure the middle position. I hear this sound which is getting louder and quiter 2 times and than get an error message "low signal to voice level". Also in this case i hear this sound from both speakers in the same time. What is strange.

I have the feeling, that i do not ave a proper channel sepration
I hope you can help me here.

Best regards
