Thanks for the help, however still the same thing - no change from the input levels but recording level remains the same.
The INPUT recording level only goes from 0 to 80 (left side buttons)...the headphone output volume goes from 0 to 100 (right-side buttons).
Which side are you manipulating?
If it is the left side and your ACG/Limiter switch on the back is OFF (switch to the left), then you may have a faulty unit. I would however start with a Factory reset...
Menu > 12 Factory reset (at the bottom of the list).
