My marantz MA500's have two RCA jacks. One is for uninverted polarity and the other inverts polarity. You can use either depending on how you want the signal delivered.You can also run these amps in bridged mode and you would connect a signal cable between the inverted input of one amp and the normal input of the second amp. Perhaps the Model 200 operates similarly.
