I have just got me an Otari MX5050 8 track reel to reel and connected my CD player direct to line input channel 1 and recorded no probs, i can now play the tape through tape return and very nice it sounds to. My problem is that when i connect channel 1 on the tape machine to group output 1 (as is the norm) on my Soundcraft Spirit Studio and route my CD player via line input i get nothing. I have signal everywhere else eg.Monitors. Can anyone please help?
