So I wanted to run some audio to my 1/4" tape machine. The Roland manual states that there are "audio outs" in the rear of the unit - they are balanced/unbalanced jacks 1/4". TS or TRS. I've used them before for headphone monitoring etc. The manual states 0DBu nominal level, so I suppose this is under line level 4 dbu. In any case, I ran TRS males from the audio outs to XLR males into the Otari. Something is a miss, because I get no audio in the Otari. I know that in the Otari, pin 3 is hot, pin 2 is cold and pin 1 is shield. This should simply invert polarity though and not cause a total dropout. There is no audio at all. When I took the same cables and plugged them into my monitors, there is audio. When I plug directly from my preamp outputs to the line in of the Otari, I get perfectly good audio. What am I missing here?
