(OR OTHER DIGITAL SURROUND MODE) CONNECTION

DOLBY PRO LOGIC (NON-DIGITAL) – SPEAKER LEVEL

Use this installation method for Dolby Digital, DTS or other dig- ital surround processors:

Use either the left or right line- level input jack for the Low- Frequency Effects channel; it doesn’t matter which one you choose.

IMPORTANT: Make sure that the LFE/Normal toggle switch

∞is in the “LFE” position. This will bypass the sub- woofer’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 full- range signal through its sub- woofer output, place the tog- gle 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 con- figured 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.

Use this installation method for Dolby Pro Logic applica- tions (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

DOLBY PRO LOGIC® (NON-DIGITAL) – LINE LEVEL

the corresponding terminals on

Use this installation method for Dolby Pro Logic applica- tions (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 sub-

woofer. IMPORTANT: Make sure that the LFE/Normal toggle switch ∞ is in the “Normal” position. This will activate the subwoofer’s low- pass filter, protecting the sub- woofer 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 sub-

woofer 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 RCA- type interconnects. Finally, plug the RCA-type intercon- nects 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 config- ured to indicate that the sub- woofer 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.

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.
