Output Impedance Switch Kit - what are the resistors for?

[Todd R]

What is the purpose of the resistors on the Output Impedance Switch Kit?
Prior to installing, when wired directly to the transformers there are no resistors involved. 

 

[Paul Birkeland]

For balanced output, a couple impedances have a center tap.  For those that don't, the pair of resistors provides the center tap.
