I guess the question should be simple: I own a Juli@ interface from ESI, it has always been a fantastic-sounding tool, and it's got a unique feature: it lets you swap the card into two positions, RCA unbalanced I/O and TRS balanced I/O. I've always stuck to the rca because I always used it solely to record synths, and they had much more volume through the rca input than the trs (some people here told me this has to do with the level of the synth outputs and that that's the way they behave as they are instruments), but the thing is that now the situation has changed (or is about to): I've acquired a mackie 402-vlz3 mixer to record basses and guitars with (perhaps some day even vocals) and I'm planning to buy a pair of decent monitors. as regards the mackie mixer, I see that its outputs are either balanced or unbal, which I guess would allow me to connect them straight to the rca inputs in juli@, and most monitors, as far as I've seen, also have either rca unbal or trs/xlr balanced inputs; so the question is... I realise that I can probably stick with the rca setup all throughout (unbal cables from the mixer into the juli@ and unbal cables from the juli@ to the monitors), but would it be sensible to do so? would I get a better sound quality if I change the whole setup toward trs balanced? (bal trs from the mixer to juli@, and bal trs from juli@ to the monitors?) is it necessary or should I try both settings up and see what happens? any help appreciated!! cheers!
