Denon pretty much use the same codes for all models though some will have more than others. I could not find a PDF code sheet for a AVC/A1XV but they should be similar to a AVR-5805CI which you can find
here if you search for "AVR-5805CI".
Denon use two IR Protocols, Sharp and Kaseikyo. You will find all the Sharp codes
here in an excel file. The Kaseikyo codes in that excel will most propably be different to the ones in the "AVR-5805CI_5805UP_IR_Codes.pdf" so you will need to dowload these programs below to generate the Kaseikyo codes if you need them.
MakeHexMakes clean IR sequences from IR protocol files. See the readme file for more information.
