[LAU] balanced <--> unbalanced

Hi, in this German document [1] Sengpil [2] added a note for balanced out ---> unbalanced in for electronically balanced out without galvanic isolation to ground. He mentioned to connect the + signal _and_ ground (not _with_ ground, just to prevent against a misunderstanding), but the - signal should be unconnected. IOW balanced out + -------------> unbalanced in - NC 0 -------------> There's a lot of chaotic half-truth about this topic in forums. Considering this document, it makes sense why not all balanced <--> unbalanced connections require the same kind of cable and especially why I didn't notice an issue for balanced <--> unbalanced connections before I got the Focusrite. However, the headphone amps of the Focusrite are still crap and apart from connecting the Focusrite blanced ---> balanced to itself, I even didn't ensure that the balanced ---> unbalanced issue mentioned by Fons is the culprit, but it could be the reason for the bad sound. It might be useful for others, too. [1] http://www.sengpielaudio.com/Geraeteverbindungen.pdf [2] http://www.sengpielaudio.com/Searchengine.htm Regards, Ralf
