mossy i have this printed out. the reason i ask about the v220 is that the gain_table.bin seems to be different than my v505. For instance when i go to change 0d which is earpece volume (original setting 01) is already at 09. Same with some of the other volumes. In this list it states that they run from 01-08. Thought the v220 is different. Maybe that the settings were different for the v220. If not how high could i go with these settings to turn the volume up.
