Dolby Pro Logic (Non-Digital) – Line Level (SCS 140 and SCS 146)

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 patch cords to connect the line-level subwoofer output on your receiver or to amplifier either

the left or right line-level input on the subwoofer. IMPORTANT: Do not use the LFE input on the subwoofer with Dolby Pro Logic processors. Note: If your receiver or amplifier has two subwoofer output jacks then

Use this installation method for Dolby Digital, DTS® or other digital surround processors: Use the line-level input jack marked “LFE” for the Low- Frequency Effects channel. 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.” The surround receiver should be configured for 6.1-channel operation (if available) and the front left, front right, center and

rear speakers should all be set to “Small.”

If your receiver allows you to set the crossover frequency between the subwoofer and the main speakers, select either 120Hz or 150Hz, or select the setting that is the closest frequency below these.
