Yeah, thats what I was going for which I thought the 9100tx was capable of dual zones/dual sources I don't beleive it can but I may be wrong. I will go look for the manual. The 1015 has more features so it is likely the 9100 can't. Just checked on the 9100 and it states multi source for the remote. Which just about all newer remotes can do. Including the 1015 remote.
