Another idea I thought up while I'm planning to make a functional 1:1 Line-Isolator & XLR splitter box for my own use. I was thinking if its feasible to add some kind of LED (as shown in pic) on the XLR Thru Out to detect phantom power in case of accidentally plugging in a stereo device to its thru splits.
Perhaps the most important question is the feasibility to convert this into a passive DI: Can I use a 2:1+1 transformer (center tapped secondary) to load down the output impedance and run maybe 25-30m of balanced cable?
As far as i understood, pure step down transformers for DI have little current loss, and 4:1 should be the better ratio to implement as well. Would the center tap draw away some currents resulting in worse signal output?
PS: Should an attenuation pad be implemented before transformer input or better at the transformer secondary output?
