Low Pass - NOTE: This control adjusts the frequency range over which
the subwoofer operates.
When using smaller main speakers, the upper range of the control will
probably yield the best results. With larger speakers, the lower end of
the control range will probably sound best, but always let your ear be
the final judge. If male vocals sound "thin"', turn this control up until the
voice sounds rich but not "boomy". If male vocals sound too "thick" or
"chesty", turn this control down until the voice sounds natural.
Phase Switch - Sit in your favorite listening position. Play music (not a
movie) with a walking bass line. We recommend playing jazz or country
music. Now listen carefully for the point at which the subwoofer
transitions to your main speakers.
This is the crossover point, and this point should be below the frequency
of a male human voice. Whichever phase setting sounds louder or fuller at
the subwoofer's crossover (transition) point is the optimum setting.
Sometimes no difference will be heard.
