I’m trying a friend’s phono preamp out and wanted to rip a couple records and compare with the NPC but no matter what I do, I can’t get the analog input to work. I’ve tried using other sources and to no avail. I’ve switched to “analog” and even tried disabling USB and switched back and forth from PCM ot DSD for kicks. I’m getting no output at all using the “analog in” input. I’m very familiar with this unit and don’t think this is user error. I’ve never tried doing this, though. Any suggestions?
