User manual POLK AUDIO PSW404

[. . . ] A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus. [. . . ] By setting the front left and right speakers to "Large" and routing them through the subwoofer as instructed above, you deliver a full range signal to the subwoofer's low pass filter. The low pass filter directs low frequencies and to the subwoofer. Full range signal is passed to the front speakers, for perfect sub/sat blending. HOOK-UP METHOD #2 (FIGURE 8) This method can be used with electronics that include a "SUB OUT" feature (Figure 8). It is not recommended for use with compact sub/sat systems. Connect a single RCA cable from the "SUB OUT" of your electronics to the LFE input of the subwoofer. This input bypasses the subwoofer's variable low pass filter and relies on the filter built into your electronics. If your "SUB OUT" is an unfiltered signal (check your owner's manual), use either left or right "Line Level Input, " to use the low pass crossover in the subwoofer. When using method #2, it is necessary to adjust the settings of your electronics as follows: Front speakers = large or small depending on their output capabilities; Subwoofer = "ON. HOOK-UP METHOD #3 (FIGURE 9) This method is for use with electronics featuring "PRE OUT" jacks--and may be used as a secondary hook up method for use with compact satellite speakers such as Polk RM Series. Connect the left and right preamp output from your electronics to the left and right LINE LEVEL input of the subwoofer. This may require use of RCA "Y" cables (not supplied) to hookup both the subwoofer and your power amplifier. When using method #3, it is necessary to adjust the settings on your preamp/processor as follows: Front speakers = LARGE; Subwoofer = "OFF" or "NO. AC POWER CONNECTION AND AUTO ON/OFF (FIGURES 10, 11 & 12) These PSW series subwoofers feature auto on/off circuitry, marked "auto" on the power switch, that automatically turns your subwoofer on when it senses a program signal. When no signal is present, the circuit turns the subwoofer off after a few 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. When the power switch is set to "OFF" (PSW303 or PSW404) or "STANDBY" (PSW505) it consumes a low amount of power. If this is a concern, you may want to leave your PSW system unplugged during extended periods of non use, such as during a vacation. 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. Adjust for deep, powerful bass without "boominess. " · Low Pass--This control adjusts the frequency range over which the subwoofer operates.
