Thread: "Normalized"
These "breakable" busses are actually really simple. What you've got is X number of outputs, but behind the panel all of the 3.5mm jacks are the type that has a "through" that can be broken when you insert a cable. That's where your "broken bus" comes out, as the jack arrangement sends signals through until it finds a cable in the bus, and the connection breaker in that jack sets up the new "output" when the cable's plugged in.
