Anyone have any insight? Sanyo manual sort of describes it for the MX-920 but I couldn't figure it out and don't want to break anything. No, this isn't a Sanyo, it's a home stereo. Please no guessing because even boneheaded me can guess, only if you have personal experience. In case you are wondering what you are looking at, they are remote multi-ganged switches that are controlled by a sleeved cable, like you would find on a bicycle or mower, except instead of a rope type cable, inside the sleeve is a flat metal strip.
