Mystery Sub Level Controller
There is a box mounted on a wall behind the TV in the living area that I haven't been able to figure out - small few inch by few inch mounted side ways with a rotating knob with labels for Min and Max, PWR with a light I've never seen lit, and marked " Sub Level " at the top.
I'm thinking it could be for the JBL subwoofer mounted nearby, but audio instructons don't mention it.
If anyone knows, please share, thanks.
