Many of us have receivers that have a switch on the back that we are instructed to throw if we need to drive speakers that have impedance of less than 8 ohms . After a search of the forum, I can't locate an explanation that describes what exactly happens inside the receiver. Is this function some sort of current protect mode for the amp or does it actually increase the current available to the affected channels? Just curious if this mode has any meaningful value - generally an amp designed to drive 8 ohm speakers does poorly when asked to drive more demanding speakers.
