Thank you much for the suggestions. I have tried the Rotel CD remote control code 0157 and 0420 many times. I also tried several other codes that I got from the Rotel web site. I still can’t control my Rotel RCD-1072 CD player using the remote control unit of my 990 preamp. I am sure that I have input the codes correctly. I can control my DVD, Dish Network Satellite receiver and Sony TV with the 990 remote without any problem.

At the moment, I do not want to try the JP1 interface as suggested by gonk. I worry that I might mess up the remote.

I am wondering whether anyone has good luck in putting the Rotel RCD-1072 under control by 990’s remote.

(I would like to mention that the original remote control unit supplied by Rotel does not have a button for power on/off. I am now powering on/off of the CD player using 990’s 2nd 12-volt trigger.)
