Hi Jim,

I have been researching this most of the day.  What I have found out the
only real choice is the single BNC Ground Loop Isolators, which is what
I have been using.  It seems that mfg's don't think it is worth the
effort to put them in a full patch bay of 16 channels.  I have given up
on my quest for this thingie.

Have a good week.

Les
