JBL SCS136 manual Dolby PRO Logic NON-DIGITAL Line Level

DOLBY PRO LOGIC (NON-DIGITAL) – LINE LEVEL

Use this installation method for Dolby Pro Logic appli- cations (not Dolby Digital, DTS or other digital process- ing), 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 outputs on your receiver or amplifier to the line-level inputs on the sub- woofer. IMPORTANT: Do not

use the LFE input on the sub- woofer with Dolby Pro Logic processors. 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 out- put jack, and connect each of the two female ends to separate RCA-type patch cords. Finally, plug the RCA- type patch cords into the line-level inputs on the sub- woofer.

Connect each speaker to the corresponding speaker terminals on your receiver or amplifier.

Make sure your receiver or processor is correctly con- figured 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 out- put, you may use the LFE input to bypass the sub- woofer’s internal crossover.

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 receiver should be config-

ured for 6.1-channel opera- tion (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.
