[. . . ] These resonances are the root cause of frequency response distortions. As an x-ray enables a physician to discover the root cause of a symptom and thereby prescribe the right treatment for a cure, this laser imaging technique allows Polk engineers to find the right combination of hightech materials, geometry and construction techniques to tune out the offending resonances. The benefit of Dynamic Balance is the dramatic improvement in the sound quality of our speakers, which every listener can appreciate. You no longer have to choose between excellent bass and smooth, clear midrange and highs. [. . . ] note that one of the terminals on the rear of the speaker is marked red (+) and the other black (-). Make certain that you connect the wire from the red (+) terminal of your amplifier to the red (+) terminal on your speaker, and the wire from the black (-) terminal of the amplifier to the black (-) terminal on your speaker. Most wire has some indication (such as color coding, ribbing, or writing) on one of the two conductors to help maintain consistency. If your speakers sound "thin" with little bass and little to no center image, odds are that one of the speaker wires is connected backwards. Strip 1/2" 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 two conductors to the receiver or amp (refer to the owner's manual supplied with your electronics for assistance with proper hookup). Connect the two conductors on the other end of the wire to the speaker terminals. To connect wire to the binding post, unscrew the plastic hex nut on the binding post and insert the bare wire into the hole near the base of the binding post. Do not insert the insulated part of the wire into the hole as this will not give you a good connection. Twist the hex nut back down the binding post until it firmly meets the wire. The RT powered loudspeakers have a built-in power amplifier and must be plugged into a standard household AC power source in order to properly operate. RT powered loudspeakers sold within North America are designed to be connected to 110-120 volt AC outlets (Figure 3). All switchable multi-voltage units are preset at the factory to operate with 220-240 volts ("230V"). They may be reset for 110-120 volts ("115V") by simply moving the voltage selector switch located on the amplifier panel (Figure 4). If you do not know your local supply voltage, consult your Polk Audio dealer before connecting the amplifier to the supply or to your other hi-fi components. to set the voltage switch , DISCONNECT THE WOOFER AMPLIFIER FROM ALL OTHER COMPONENTS AND FROM THE MAIN ELECTRICAL SUPPLY OUTLET. Insert a small flat blade screwdriver into the recessed slot of the switch and move the slide fully in the direction marked with the desired supply voltage range. The power switch has two positions: "Off" and "Auto. " In the "Auto" position, the amplifier will automatically turn on as soon as the speaker senses a signal coming from your pre-amp, integrated amp or receiver. In this mode the subwoofer amplifier will turn off several minutes after signals cease to be sent by your pre-amp, integrated amp or receiver. - when using subwoofer line level input Remove jumpers when using subwoofer line level input (see owner's manual).
