Is it wrong to use a regular cable (no transformer) to connect the XLR main and submix group outputs of a console to the TRS (balanced) inputs of an audio card, or should impedance matching be done in that case? It is quite common in music stores these days to find cables that are XLR male on one end and TRS male on the other. (I'm currently using those on my mixer outputs.) The cables *are* balanced, but they do not contain a transformer at all. The impedance of my console's main/submix outputs is rated as less than 75 ohms, but the input impedance of my audio card is 10k ohm. This would seem to almost answer the question by itself, it weren't for the near impossibility of actually finding a matching transformer that's TRS and not TS on its 1/4" end. I looked at a lot of them. They're all made for hooking up guitars, amps, and mics, and they all seem to have an unbalanced plug opposite from the XLR end. If there is indeed a need transformers on each XLR mixer output in this instance, where can I get one that won't unbalance the connection in the process? Or is it fine to just use these common XLR->TRS cables that don't have any? The reason I started to investigate this is because I'm not sure I'm not getting some of the "tone suck" you might associate with a badly matched connection, and this seems a likely cause. Addendum: On the realtime end of things, I'm now achievable a solid, unbreakable 2ms. I can't seem to do anything that causes an xrun. That's good at least! -- + Brent A.
