So here is my dilemma. I have been a vinyl DJ since I started and have had 1200's and a mixer for forever. A few years ago I added the digital side and integrated an S4 into my system. The S4 output runs through a dedicated channel on my DJM1000. My 3 turntables also occupy a channel each on the 1000. I purchased the timecode vinyl and scratch upgrade and figured that I could simply split the signal between the turntable and then run it to the S4 and the mixer from there. This is where the problem began. I have tried passive and active splitters in between the turntables and mixer/S4, but Traktor always shows the signal is low, it throws ground and skip errors and sometimes even runs backwards? I was hoping to find out if by integrating a scratch A6 into the system it may solve these issues. Therefore being able to play my turntables normally through my mixer by switching it straight through the A6, and also being able to use them and the timecode through the S4/Traktor to control the digital tracks, without having to swap cables constantly. I asked tech support many times about integrating an A6 and all I was told was "remove the splitters." Yes... of course I could do that, but then I lose the functionality of having my turntables being run directly to my mixer. I know and understand that I can switch the turntables straight through the S4 to use them as normal, but I don't want lose the ability to still be able to use them strictly through my mixer, without the S4 in the loop. However before I decide to spend the money on trying to integrate an A6 I would like to know some answers to some fundamental questions, to understand if this is a feasible solution. I asked tech support these many times, but all they did was refer me to the forums. I have attached a pdf document diagram of how I want to connect things, to assist in answering the following questions I posed: Is this even possible, at all?? Will the audio and cue from the turntables when used through the S4/Traktor software still have the output through the headphone jack on the S4, not the A6 hardware? Will I be able to control the pass through switch for the A6 in the Traktor scratch software, or is it separate software that is for the A6? If I was to hook it up this way, where would I hook the ground for the turntables? To the A6, as it sends a line level signal to the mixer? Is this the best way to do it, or does anyone have any other suggestions? I have looked at and considered a plain old physical switch so that there is no "split" as such. Not sure how fussy the timecode stuff is and if that would cause issues? Surely someone has wanted to do this before me? Any input on this subject would be very much appreciated!
