Not sure this is the right forum for this. Like many people, I have a large collection of vinyl and tapes that I'd like to begin converting to digital. I already have this device https://www.amazon.com/M-Audio-Track-Mobile-Interface-Preamps/dp/B000BD31ZW that I use to do guitar recordings directly into my computer garageband software, so I was wondering if all I'd need would be RCA to 1/4" cables? I assume I could run cables from my (vintage!) Kenwood receiver's RCA output jacks into the M-audio's mic / instrument inputs? Or won't that work? Someone suggested that I should use RCA to RCA and use the "unbalanced" outputs (wouldn't that be inputs?) on the M-audio. I've never done any of this transferring before so need to know how best to accomplish it. Thanks....
