Its pretty frustrating - I tried to do a search for "xlr" (no quotes) - because I remember some folks mentioned a good adapter to use on the 5235 active crossover to get away from the balanced type connectors for home use.
Well, no results on my search for xlr ...
Have you tried letting the local Google search parse the Lansing site??
I made a demo of what I am talking about here:
I set it to search the whole site beginning at http://audioheritage.org/
Type XLR into THAT box and google returns all the occurances of XLR on the site!
Type XLR + 5235 and it returns just two threads ...
and this turned out to be the thread I needed -
If you like I could send you the html code to plug into a page here ...
Google is pretty good about sharing their databases with end users
(After all, it IS your content!)
