The international symbol of a lightning bolt inside a triangle is intended to caution you to uninsulated "dangerous voltage" within the device's enclosure. [. . . ] It does not matter which wire conductor is connected to the positive or negative connection of your equipment as long as you are consistent. Be sure that the connections from the amp to all of the speakers in your system are connected in a like manner. If this is not done, the quantity of bass will be reduced and the stereo image will be compromised. Be careful to avoid excess bare wire or loose strands of wire at the connections. This could cause a shorting condition between adjacent positive and negative terminals, damaging your speakers and amplifier. LINE LEVEL CONNECTIONS These connections should be made using high quality shielded interconnect cables terminated with RCA phono plugs. These cables should be as short as possible and kept away from noise generating electrical equipment such as digital electronics or electric motors. Consult your Klipsch dealer for specific cable recommendations. "LINE IN" / ALL MODELS For best results, these jacks should be connected to a non-filtered (full-range) subwoofer or main channel pre-amp output on your receiver or pre-amp/processor. This input signal should contain the normal bass information present in the main left and right channels. When connecting to a component that has only a single pair of pre-amp outputs, "Y" adapters (splitters) may be used to feed a signal to both the subwoofer and the power amplifier. "LINE IN" / KSW 10 and 12 ONLY You can connect a mono subwoofer output on your electronics to the "L/LFE" input using a single interconnect cable. If there is an inadequate amount of subwoofer volume even with the level control set to maximum, add a "Y" cord to the subwoofer end of the cable and connect to both line inputs. This will provide a significant (6dB) increase in the subwoofer's output level. "LINE OUT" / KSW 15 ONLY If a bass limited (high pass filtered) signal is to be sent to your main speakers, connect the "LINE OUT" jacks on the subwoofer to the line level inputs on your main channel power amplifier.

There may be several options for placement of the subwoofer in your room that will effect its frequency response and output level. Corner placement improves the acoustic loading of the subwoofer, increasing its output and dynamic range capabilities. Placing the subwoofer away from walls or in the center of the room will result in the least amount of output. Asymmetrical placement of two subwoofers in a room may improve low frequency reproduction by providing a smoother and more consistent response pattern. Since even minor repositioning will result in an audible performance change due to room acoustics, Klipsch recommends experimentation with the subwoofer placement in the room. A general rule of thumb is to place your subwoofer in the vicinity of the speakers with which it is being paired. For example, a subwoofer reproducing front channel bass will generally perform better when placed in the same end of the room as the main speakers. As well, a subwoofer connected to the rear channels of a surround system performs best when positioned in the rear of the room. If the subwoofer is installed near your television and color distortion is noted, simply move the subwoofer farther away from your television until the interference disappears. If your subwoofer is placed in an enclosed cabinet, provisions must be made to ventilate the heat radiated by the enclosed amplifier. Additionally, since some of the acoustic output is generated by the sub's rear firing port, a minimum of several inches of space should be provided around the subwoofer. [. . . ] The proper setting of this control is affected by room acoustics and the placement of the subwoofer in the room. You may need to repeat this procedure if the subwoofer is repositioned. Troubleshooting · If your subwoofer has little or no output: -- Double check your power (AC) and system connections. -- Make sure that the "POWER" switch on the rear control panel is in the "ON" or "AUTO" position. -- Ensure that the "POWER" light on the front of the cabinet is lit.
