DOLBY® DIGITAL OR DTS® (OR OTHER DIGITAL SURROUND MODE) CONNECTION IMPORTANT: Make sure that the LFE/Normal toggle switch � is in the �LFE� position. This will bypass the subwoofer�s normal low-pass filter, reducing the possibility of signal degradation and more accurately reproducing the program materials. However, if your receiver is passing a fullrange signal through its subwoofer output, place the toggle switch in the �Normal� position, which will activate the low-pass filter and protect the subwoofer from possible damage. Connect this jack to the LFE output or subwoofer output on your receiver or amplifier. Connect each speaker to the corresponding speaker terminals on your receiver or amplifier. Make sure that you have configured your surround sound processor for �Subwoofer On.� Also, remember to configure your receiver for 5.1-, 6.1- or 7.1-channel operation as appropriate. DOLBY PRO LOGIC (NON-DIGITAL) � SPEAKER LEVEL Use this installation method for Dolby Pro Logic applications (not Dolby Digital, DTS or other digital processing), where the receiver/processor does not have a subwoofer output, or a volume-controlled preamp (line-) level output: Connect your receiver or amplifier�s front left and right speaker terminals to the left and right terminals on the subwoofer that are marked �Speaker Level In.� Connect the left and right terminals on the subwoofer that are marked �Speaker Level Out� to the corresponding terminals on the back of your front left and right speakers. Connect your receiver or amplifier�s center, surround and surround back speaker terminals to the corresponding terminals on the back of your center and surround speakers.

Use this installation method for Dolby Digital, DTS or other digital surround processors: Use either the left or right linelevel input jack for the LowFrequency Effects channel; it doesn�t matter which one you choose.

DOLBY PRO LOGIC® (NON-DIGITAL) � LINE LEVEL Use this installation method for Dolby Pro Logic applications (not Dolby Digital, DTS or other digital processing), where the receiver/processor is equipped with a subwoofer output, or a volume-controlled preamp (line-) level output: Use RCA-type interconnects to connect the line-level subwoofer outputs on your receiver or amplifier to the line-level inputs on the subwoofer. IMPORTANT: Make sure that the LFE/Normal toggle switch � is in the �Normal� position. This will activate the subwoofer�s lowpass filter, protecting the subwoofer from possible damage and enabling it to operate most efficiently by reproducing only the low-frequency materials that it is best at handling. NOTE: If your receiver or amplifier only has one subwoofer output jack, then you will need to use a Y-connector (not included). Plug the male end of the Y-connector into your receiver or amplifier�s subwoofer output jack, and connect each of the two female ends to separate RCAtype interconnects. Finally, plug the RCA-type interconnects into the line-level inputs on the subwoofer. Connect each speaker to the corresponding speaker terminals on your receiver or amplifier. Make sure your receiver or processor is correctly configured to indicate that the subwoofer is �On.� Note for advanced users: If your receiver/processor has a built-in low-pass crossover filter for the subwoofer output, you may switch the LFE/ Normal toggle switch to the �LFE� position to bypass the subwoofer�s internal crossover.
