It is going to very from machine to machine. I had one that served a newer stern and an older bally on the two inputs and it was very hard to compromise on the settings for them both to sound great. I changed the sub to serve two modern sterns on the two inputs and it was still very difficult to find a balance between the two.
Each pin seems to need is own settings unique to itself to sound it's best and those settings can really vary from pin to pin.
Good luck
