Powering Your Subwoofer Your system includes a detachable power cord that's packaged separately from the cabinet. Insert female end into the receptacle on the amplifier plate and insert the polarized AC plug into a wall outlet (or power strip). We do not recommend connecting the subwoofer's AC power cord to your receiver's switched outlet. Adjusting Your System Subwoofer Adjustments Your powered subwoofer offers a range of setting options. We recommend the following settings as starting points, but the settings that are best for you depend on 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. AC Power Connection and Auto On/Off Your subwoofer features circuitry which automatically turns your subwoofer on when it senses an audio signal. When no signal is present, the subwoofer goes into standby after 20 minutes. Fine Tuning your Subwoofer • V olume-When you set up your subwoofer for the first time, you may have to make adjustments several times before you hear what you personally like. Start with the volume at 50%. Adjust by ear using a wide variety of CDs and video sources. Adjust for deep, powerful bass without "boominess." • L ow Pass-NOTE: This control does not work when the subwoofer is connected with the LFE Input. This control adjusts the frequency range over which the subwoofer operates. When using smaller main speakers, the upper range of the control will probably yield the best results. With larger speakers, the lower end of the control range will probably sound best, but always let your ear be the final judge. 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. • P hase Switch-Sit in your favorite listening position. Play music (not a movie) with a walking bass line. We recommend playing jazz or country music. 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. Sometimes no difference will be heard. DC Control (12v Trigger) The DC Control input lets you power on/off the subwoofer and other home theater equipment (ex. amplifier or receiver) at the same time, while also providing a faster way to power on the subwoofer than normal signal detection. To get the most from the DC Control's functionality, connect the DC input (12V) on your subwoofer to the DC output (12V) on your receiver or amplifier using a 1/8" TS cable. Be sure to switch your subwoofer to DC Control/12V Trigger mode. When the subwoofer receives the 12V input it will immediately turn on, and stay on, until it stops receiving a 12V signal. If you want to use the signal detect function, simply restart the subwoofer by switching the power switch to "Off," wait 10 seconds, and then flip it back to "Auto On." Troubleshooting When connecting your cables, always make sure the subwoofer is turned off to prevent any/all damage. No sound is coming from subwoofer or the subwoofer doesn't sound right If connection is set from your receiver's 'sub out' to the subwoofer LFE, check the receiver is configured to enable the subwoofer (see receiver owner's manual for more information). Subwoofer has no power Check outlet; check fuse after unplugging the subwoofer.
