Here's the
complete set of IR codes for the 575. These need to be
converted to Pronto Hex. Take the IR code listed in the Yamaha PDF files, and substitute a space for the hyphen, and enter that into the Yamaha Pront Hex converter.
For example HDMI1 (main zone) is shown as 7A-4738. Enter 7A 4738 into the converter. If you don't include the space or put it in the wrong position, the converted Pronto Hex will be incorrect.
