The phase switch switches the phase http://www.avsforum.com/ubb/smile.gif . This effectively reverses the positive and negative terminals coming into the sub. Depending on the sub the input may be a RCA connector and there is no other way to reverse the phase. Ideally you want the phase to be the same as the phase as your other speakers. Although depending on the location of your sub in relation to your other speakers it might sound better out of phase. The best way to do this is to sit in the optimum listening position and have someone flip the switch and see which sounds better. It is better to do this with a test tone than actual music or soundtrack.
The low-pass setting selects the frequency at which the sub-woofer kicks in. If you have large front/center/right speakers (8" or larger bass speakers) then the low-pass selector should probably be in th 80-100hz range. If your other speakers are smaller then increase the crossover frequency into the 100-120hz range.
