To be honest, I don't know what it does mean exactly. It's the
 different kind of PSU...switched/unswitched...
 I've been told that PC Power Supplies are Switched which is not the
 best for a doepfer modular. However I'm using 3 of them in my modular
 and everything seems OK...at least for 99% of my modules...
 try searching old posts, there were other discussions on this
 subject...
