Ralph, can you explain why on Earth some designers and makers of consumer electronics go to the trouble and expensive of providing balanced connections (if not circuits), and then don't do it "correctly", to conform to the AES standard? To do that defeats the whole purpose of balanced! It costs no more to do it right, either. Just connect the correct wires to the correct XLR pins. Duh.My guess is that they don't know about the standard, don't care, don't want to the expense and stigma of an output transformer or some combination thereof.
The only other way to really do it right (so the output really does ignore ground) is the way we do it, which is patented.
