I'm trying to find discrete codes for specific volume settings for my Marantz SR7007....for example, the ability to set the volume to -50 dB or -35 dB, etc etc.

Are there any discrete codes in Pronto Hex format for this kind of manipulation?

Thanks!

 You can set discrete levels of volume with 1 dB of settability.  For the Main Zone, the signals are RC5x, device 16.111.   You can download the spreadsheet which has all possible IR signals listed.

To convert the RC5x signals into Pronto Hex format, use IrMaster, select RC5x, enter 16 into the D field, 111 into the S field, and e.g. 35 into the F field to get a -35dB signal.
