I have a MZ-RH710 (I live in south america so i dont know why i have a european version!) your MoD worked perfectly!!!!!!! THANKS, YOU SAVE ME FROM DUMP THIS TO THE TRASH!!! The first time i listened and saw the ridiculous low volume and no custom eq. I couldn't believe it!, my previous MZN-510 was way too much powerfull and a excellent low and bass settings. If one wants to damage is own hearing you must have the privelege to do it, at the end it's only yourself the one that will be damaged!, this restriction is plain stupid. the only difference in you procedure was that I found a number increasing insted of DistFL, that number finished with A0, changed it to 24 and save settings and it worked!! thanks a lot really! iNd
