I have a denon 3803, I set the remote up yesterday with codes to control all my components. I want it to learn the codes for going directly to -20db -10db etc on the 3803. These codes are not preset into the unit so I will need to buy a remote that has these commands preset and then transfern them to the denon remote. What is the cheapest remote available that can do these commands? Am I missing something, is there an easier way to do this? Thanks.
