For what reason? I seem to understand it quite well. If you have a differential signal from a DAC to an amp, you need +X, ground and -X. 3 lines per channel its that simple... And despite what some folks think, -X and -Y should not be used as "grounds" for single ended amps...DZ, I suggest you take up the inquiry with Bill or VaThInK.
I'm not quite sure I understand how floating V- has become part of this thread, did I miss something? This is something completely different and has nothing to do with sending a signal to an amp.I think leaving the V- floating would cause bother.
I wasn't aware that the Flashback had single-ended outputs. I think that you can just tie the -X and -Y inputs on the amp to ground and it should work fine. I had a set of DT-40pro's for a while and I think thats what I did when I was running single ended from LD2K. Either that or I just left -X floating, I'd try with it floating first and if that looks bad, just ground it.The Flashback has single-ended outputs
