Can anyone can tell me how to isolate the discrete "power off" for an individual Sony component, I would really appreciate it. I would like to program "power-off" on my amp into a macro without having to shut everything else off. I know that signal is in the 3000 somewhere, but the only way I've been able to use it is by activating the entire system off feature which rapidly scrolls through each component's discrete off signal.

I don't think that code is in the remote. You may need to get the code off this website and program it into the 3000. That may prove to be difficult due to the fact that you need a computer hook-up type remtoe (pronto, marantz, etc). Sony has a "Master off" command that no matter what the device is (TV, VCR, amp, DVD, etc)...it will turn it off. More than likely, that is the command in the 3000 that is turning off your amp. If you can't get your hands on the code I mentioned above, you may want to think about a backwards approach...make your macro turn everything off, then turn on the items you want to keep on...
Just a thought.

I figured out how to isolate each power off using my old RM-AV2000. From another thread...
I noticed that on that unit, when I did a "system off," the commander first sends out a universal signal that shuts down most Sony's in one shot. It then scroll’s through (slowly) individual power-off's for each component. In my case, I only needed the amp shut off.
This is what I did:
First, I put the 3000 into learn mode. I then choose a function on a component that I do not use (i.e.: “1” on “DVD2”). I then push the key to be taught, then I quickly hold down the “system off” command on my old unit. Here’s the tricky part: I actually keep the teaching remote POINTED AWAY from the learning remote. When the discrete “power-off” command for my particular component poped-up, I quickly point the remote at my 3000. It worked on my first try! I now have isolated my discrete “power-off” for my amp. I will do the same for other components as well.
