[. . . ] After you've become familiar with what the settings do, experiment with alternate options to find the method that works best for your system setup. Note: When you set up your subwoofer for the first time, you will probably have to make adjustments several times before you hear what you personally like. AC POWER CONNECTION AND AUTO ON/OFF Your subwoofer features auto on/off circuitry, marked "auto" on the power switch, which automatically turns your subwoofer on when it senses a program signal. We recommend the "auto" setting if your subwoofer is always receiving power (ie, if it's plugged into a wall outlet). When no signal is present, the circuit turns the subwoofer off after 15 minutes. If you are concerned about the brief delay between when the music starts and when the subwoofer turns on, simply leave your subwoofer in the "On" position. You may want to leave your system unplugged during extended periods of non use, such as during a vacation. " · Low Pass--NOTE: This control should be turned all the way up when the subwoofer is connected with Method #1 (LINE IN). This control adjusts the frequency range over which the subwoofer operates. 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. 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.
