I seriously dont know what i could possibly put as a title for this post, so apologies for that.
Im digging into a piece of gear that I am trying to mod for a friend of mine and i ran into something kind of odd (well, odd to me since ive never run into it before). There is a switch on the unit that takes the hot and cold input signal and runs the hot through resistor A and cold through resistor B. The switch has 4 settings, but only one of these settings does this where hot goes through say a 100K resistor and cold goes through a 110K resistor. From there it seems the signal goes into a transformer and then to the rest of the circuit. Im guessing that the other functions (where the resistors are matched) is just helping to load the transformer a little differently, but the one where they are mis-matched... whats the science behind that?
