I went through the same thing renaming and setting the gains correctly per device on a C2500. I'm just glad they had the option. Made a lot of difference. I never did use the remote. I changed from a C20 to a C2500. There was a heck of a learning curve. I love that remote though.
The one issue I have is remote assignment. I have a few Macs the remote on one will change the setting on the other, MX150 and C2500. I haven't used the surround in 10 years. The only reason it's there, the C2500 is in for a repair.
I'll be going through the two day set up when it comes back. Be nice if it had access through a laptop or a smartphone for a working KB input. Maybe it does.!?
The bass system I use has easy access via laptop. Set in the drivers seat and listen to the changes. Pretty cool actually.
Enjoy in any case.
