WARNING: Listen Carefully Polk Audio loudspeakers and subwoofers are capable of playing at extremely high volume levels, which could cause serious or permanent hearing damage. [. . . ] " · Depending on your speakers' bass output capabilities, set the crossover frequency on the receiver to 80Hz for tower and bookshelf speakers (speakers with a woofer 5 1/4" in diameter or larger) and 100-120Hz for satellite speakers. " If you elect to use the speaker level inputs, use two-conductor 16 gauge or thicker speaker wires. Make certain that you connect the wire from the red (+) terminal of your receiver to the red (+) terminal on your speaker, and the wire from the black (-) terminal of the receiver to the black (-) terminal on your speaker. Speaker wire has some indication (such as color coding, ribbing, or writing) on one of the two conductors to help maintain consistency. If your subwoofer doesn't seem to produce much bass, it is most likely that one of the speaker wires is connected backwards. Strip 1/2" (12mm) of insulation from each of the two conductors on both ends to expose the bare wire. Twist the exposed wire of each conductor to form two un-frayed strands. ⷠConnect the left and right front speaker outputs of your receiver to the speaker level inputs of the powered subwoofer using speaker wire. ⷠThen, connect the left and right front speakers using speaker wire from the speaker level outputs from the powered subwoofer. ⷠConnect the Center Channel Speaker directly to the center channel output from your receiver. OPTION #3-- Receivers with full-range (unfiltered) Left and Right "Pre Out" jacks (this is the least commonly used hookup). ⷠConnect the left and right preamp output from your receiver to the left and right LINE LEVEL input of the subwoofer. When using method #3, it is necessary to adjust the settings on your receiver as follows: · We recommend the following settings as starting points, but the settings that are best for you depend upon your speaker placement, electronics and personal taste. 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 PSW Series 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 PSW system unplugged during extended periods of non use, such as during a vacation. " · Low Pass--NOTE: This control does not operate when the subwoofer is connected with Method #1 (LFE Input). This control adjusts the frequency range over which the subwoofer operates.
