RTA will not tell you, but I don't know that you will believe me either. You need an oscilloscope to test a signal, but to test an input, you either need to trace the PCB out and see the devices, or you need to believe the brochure.

1)So, is there a converter for balanced-to-unbalanced only purpose? I plan to use audison LRx , but the dealer told me LRx does not accept balanced signal.
2) BMW only use two wires to transmit balanced signal. Maybe one wire is +5V, the other wire is -5V.
