I've just begun to record outside of the virtual realm and now that I've started to work with outboard gear such as pre's, mics and guitars I'm unsure of which cables to use for which applications. Please, indulge me: -Are all TRS 1/4 cables suitable for balanced inputs/outputs? What are the differences between balanced & unbalanced? -What type of cable should be used in a situation where a DI, for example, has a Hi Z 1/4 input? TRS or tip-ring? Which for Lo Z? -Do the differences between Hi an Lo Z refer to impedence? -Is it better to use matching cable types on your I/O? For example, XLR on the input but 1/4 on the output. Beneficial to have XLR on the output as well? It's these rudimentary chips of knowledge that are hopefully gonna save me time and money. Hope those questions made a little sense.
