Long story short, I am recording voice-overs so I need a USB PC friendly interface. I'll be using a Shure SM7B (client request), so I need something with quality, low noise, high gain pres. One (or two) channels is fine. Wall power or bus powered isn't a factor to me, as long as the pres have plenty of headroom for dynamic microphone voice recordings (which I would assume would be limited by bus power, but I am not sure). I would use the Apogee One (which has 65 db of gain on tap) but it is mac only and I'll be using a PC. I am thinking I need at least 50 db of gain in the pres. Ideas? Your input is appreciated!
