Re: RME Fireface 400 and Guitar Hi-Z inputs
Kris - you'll get plenty of more-well-informed answers, I'm sure. But in the simple way that I understand it, hi-z refers to the high impedance value of the input. Matching impedance with an audio connection is important in order to get the best s/n ratio. A guitar's instrument-level signal is also a high impedance signal, and if you plug it into a jack designed *exclusively* for line level signals - you'll have a mismatch resulting in noise and/or bad signal degradation.
A lot of devices now have inputs that claim to "adjust" impedance based on what's plugged in (and perhaps a switch setting on the device somewhere).
Regardless, in my experience you will lose a lot of high end *and* low end if you plug a hi-z instrument into a low-z input. Sounds icky. :(

So what will a hi-z give me that will make any audible difference, from the
line input of the FW 400 adjusted to the correct level on my
guitar?
