The right most slider is labeled "PHASE" - this allows you to adjust for out-of-phase wiring or other out of phase situations. Explaining sound phasing is a whole other issue (try google if you really want to know), but as long as your system is wired correctly, this is not something you should have to worry about - leave it at 0.

 

The left switch is labeled "ISF". This is an Infrasonic filter switch. In brief, even sub-woofers can have issues replicating certain sounds below ~15Hz-25Hz or so. In an attempt to recreate these low frequencies it can start making odd sounds, distortion, or conflicting waves which might lead to phasing or other issues. This switch allows you to "cut off" below the selected frequency so the amp/sub will not reproduce anything below that frequency. Try the switch at 15Hz, if you notice you are having odd sounds issues with the sub, try it at 25Hz.
