My subwoofer is in the conrer of my room. Theres a switch for those 2 options, which do i use?

Also, there is a LOW PASS knob. how much do i turn that up? Alongside a volume knob.

Phase switch is there to allow more flexibility for sub placement. Generally, if it is up front then it is set to zero degrees and if at rear, then 180 degrees. You set it to the one where it plays the louder.
