Same here, it's like the input 'rotary knob' is a switch between 'on' and 'off'. Only when it's at his highest level it gives a satisfying input signal....... No subtile diffecrences can be made. (is this what they call 'there's no headroom'?)
I'm working with an Rode NT1A mike (yes, phantompower is 'on') and the presonus is new. Installed software on windows as well as mac......
Anyone?
