Doepfer

Hi thanks everybody for replying
The situation was vague indeed, sorry, though the patch is very basic
The case is just 1 row (LC3)
As you can see by the colours on the following screenshot, the multed audio 1 signal (red cable) is slightly affected by the audio 2 signal (blue cable), as we turn CW the A-138s channel volume knob.

Nothing else is patched/ engaged.

I unfortunately have no means nor expertise for measuring anything.
ASAP I will first try installing the multiple on another case.

Best, Diego
