[quote author=”beatles”](a) because ESI Juli@ had balanced and un-balanced I/O connectors (but cannot used simultaneously); which one do you prefer?[/quote]
Actually, they can. I tried it, was very surprised that it worked, but it did.
[quote author=”beatles”](b) if I want use balanced input, but need un-balanced for MPX output (because almost all FM Exciter use un-balanced MPX input); how can I do that?[/quote]
By running the MPX cable into the computer through a convenient hole, and connecting it to the unbalanced output inside the computer.
