One more R44 caveat that I learned last night.
Been running these decks for a long time now and this one just got solved.
I had a hard time synching the digital signal from the V3 and tried everything: switching the sample size, plugging and unplugging, switching decks, restarting....
Finally I noticed that the phantom power was on for Channels 1 & 2 and turning that off, shutting down both the V3 & R44 and starting over fixed it right up. So there is, I believe, the main reason that sometimes the R44 doesn't take the digital signal from time to time!
