Holger, Great looking front panel layout especially in 1 unit high rack
Do you have any photos of the inside?
I moved your photos to our server as they were not showing for some reason.

Sure, once it is finished I'll take some detailed shots.

Was this with the Statten board and your own concentric pots? Would love to see the insides! Thanks

Hi again, I'm trying to understand how this unit works because I'm interested in building something similar. Is it really a 8x8 matrix where you can send input 1 to any of the 8 outputs with just one knob? I also see 8 master out levels. In the picture it looks like the boards are called AUX8SUM but I don't see those on the site, just the AUX8 and the SUM8. I'm guessing the board on the right that controls the output levels is the SUM8 since it has all the ICs on it, but I'm confused about the other four front panel boards and how they work together.
Thank you!

This unit has odd to odd numbers and even to even numbers so basically think of it as 4 x 4 stereo. To do full 8 x 8 mono just use an extra AUX8 pcb so you would have each aux pcb section as an input so full 8 x 8 matrix with 8 master output levels on the SUM8 pcb.
