    no, i just cut it on the mainboard side. if i can easily reconnect it, i'll try to cut it on the IO board...
  • Make sure that where you disconnect it, the ground leads of the individual channels are separated from each other. If you leave them together you will still have a loop.
  • replaced the caps in the master section with better caps, and since i cut the old cable, installed a mic cable that has a good shield, still noise
  • i don't know what happened, i have no noise anymore, the last thing i did was put in sockets in the 22k spots, with resistors, still had noise, and took them out again, but i'm not sure if the noise at that point was gone, i just noticed few days ago.. also no LED interference. owell don't care, noise is gone
  • Anyone here who's bd sounds 100% the same on both mix out and separate out? I can hear an audible difference (less bass due to minimal distortion on mix out). The mod didn't make any difference...
  • No one hear with a little less low end frequency response at the mix out compared to the seperate outs? Could it be the caps in the master section that filter out some of the low end?
  • Ok, I just found this discussion here on Gearslutz:

    Looks like the original TR909 is also filtering out some low end through the mix outs... So obviously normal behaviour. :roll:
  • Also very interesting:

    I will try replacing the caps with 10uf ones as I don't want to lose all that bottom end on the main outs.
  • I heart from the another unit and the noisy mix out. It really works.
