I too am a BIG EAD/Alpha digital fan, I have been up the food chain from Encore to Signature to Pro 8000 and now Pro 8800 and the answeres are correct the pass thru is indeed that, how ever a little bird told me there are some new software versions on the way I doubt that the pass thru will be affected but it may facilitate the bass management you might want to call Steve at EAD and ask. I just installed the new e-prom and it was a snap so my auto-setup went smooth as silk. Don't hesitate going with Ead, great gear and even better customer support. Good luck and good listening!
