No, this is standard terminology for a standard configuration. Each speaker 
presents a 600-ohm load to the amp through transformer coupling. This is 
why standard studio headphones were (and on occasion still are) 600-ohm 
impedance.

I'm fuzzy on specifics; I've not worked with such a setup for several decades.
