I'm guessing a simple transformer should do the trick, but the question is: WHICH transformer? What should the specs be in order to get the impedance right for both sides?
Don't worry about impedances, they don't have to be matched
unless there's a few km of wire between the two.
Headphone out is low Z, amp in will be 10k or more. Any line
level 1:1 audio transfo will do. You can by them as XLR inserts
or just bare.Ciao,
