CBTL Posted November 27, 2016 Share Posted November 27, 2016 Sorry for such a simple question. I conect my helix to a tech 21 power engine via 1/4" (it also has XLR) should I set to line or instrument/amp? What is the actual difference? Would I be better using the XLR?

zooey Posted November 27, 2016 Share Posted November 27, 2016 Basically, I'd go line level XLR if you don't have any reason not to. Line vs Instrument is just higher signal level. Looks like the PE can handle either, just adjust its input level so it doesn't clip. Line would provide somewhat better environmental noise rejection since the signal is hotter in comparison. Re XLR vs 1/4", XLRs are balanced, so any hum from AC lines etc theoretically gets rejected. Balanced also lets you lift the ground, to avoid ground loops. 1 Quote Link to comment Share on other sites More sharing options...
