CAUTION We, Harman Consumer International 2, route de Tours 72500 Château-du-Loir France declare in own responsibility, that the product described in this owner's manual is in compliance with technical standards: EN 60065:1998 EN 55013/A14:1999 EN 55020/A14:1999 EN 61000-3-2/A14:2000 EN 61000-3-3/1.1995 EN 50081-1:1992 EN 50082-1:1992 2 Gary Mardell JBL, Harman Consumer International France, 08/03 SPEAKER PLACEMENT Front Speakers Center Channel Speaker Subwoofer 0 ­ 0.61m (0 ­ 2 ft.) Surround Speakers (SCS 140) placed on a wall behind the listening position, facing forward. The surround back speaker (in SCS 146 only) should be placed behind the listening position, facing the center speaker. The surround speakers should not call attention to themselves. Experiment with their placement until you hear a diffuse, ambient sound accompanying the mainprogram material heard in the front speakers. The low-frequency material reproduced by the subwoofer is mostly omnidirectional, and this speaker may be placed in a convenient location in the room. However, the best reproduction of bass will be heard when the subwoofer is placed in a corner along the same wall as the front speakers. Experiment with subwoofer placement by temporarily placing the subwoofer in the listening position and moving around the room until the bass reproduction is best. Place the subwoofer in that location. 1.52 ­ 1.83m (5 ­ 6 ft.) Surround Speakers (SCS 146) 1.52 ­ 1.83m (5 ­ 6 ft.) The front speakers should be placed the same distance from each other as they are from the listening position. They should be placed at about the same height from the floor as the listeners' ears will be, or they may be angled toward the listeners. The center channel speaker should be placed slightly behind the front left and right speakers, and no more than two feet above or below the tweeters of the left and right speakers. It is often convenient to set the center speaker on top of the television set, as shown in the drawing. Use the supplied support leg to aim it toward the listener by screwing the leg in to angle the speaker up, or unscrewing the leg slightly to angle the speaker down. The two surround speakers should be placed slightly behind the listening position and, ideally, should face each other and be at a level higher than the listeners' ears. If that is not possible, they may be 3 MOUNTING OPTIONS Satellites and Surrounds On shelves. On the wall. Wall brackets are included. On optional stands (FS300S). Wall-Mounting Attach plate to wall. The brackets should be placed, if possible, so that the screws will fasten into a wooden wall stud. If that is not possible, use properly selected wall anchors. Slide speaker onto support. Place speaker and support on wall plate. The customer is responsible for proper selection and use of mounting hardware, available through hardware stores, to properly and safely wallmount the speakers. 4 SPEAKER CONNECTIONS Connection Tips Separate and strip the ends of the speaker wire as shown. Speakers and electronics terminals have corresponding (+) and (­) terminals. Most manufacturers of speakers and electronics, including JBL, use red to denote the (+) terminal and black for the (­) terminal. The (+) lead of the speaker wire is noted with a stripe. It is important to connect all speakers identically: (+) on the speaker to (+) on the amplifier and (­) on the speaker to (­) on the amplifier. Wiring "out of phase" results in thin sound, weak bass and a poor stereo image. With the advent of multichannel surround-sound systems, connecting all of the speakers in your system with the correct polarity remains equally important in order to preserve the proper ambience and directionality of the program material. 5 Dolby* Pro Logic* (Non-Digital) ­ Speaker 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 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 "High Level In." Connect the left and right terminals on the subwoofer that are marked "High Level Out" to the corresponding terminals on the back of your front left and right speakers. Connect your receiver or amplifier's center, left and right surround-speaker terminals to the corresponding terminals on the back of your center, left and right surround speakers.

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 you can plug the RCA-type patch cords into both left and right line-level inputs on the subwoofer. Connect each speaker to the corresponding speaker terminals on your receiver or amplifier. + ­ R L + + ­ ­ Left Surround Center Surround Back Right Surround + ­ + ­ + ­ Left Surround + ­ Surround Back + ­ Right Surround + ­ Only in 6.1 systems Dolby Digital or DTS® (or Other Digital Surround Mode) Connection (SCS 140 and SCS 146) RECEIVER SUBWOOFER LINE LEVEL IN LFE OUT LFE INPUT L R Use this installation method for Dolby Digital, DTS® or other digital surround processors: Use the line-level input jack marked "LFE" for the LowFrequency 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. 7 O P E R AT I O N Move the Master Power switch (marked "Power" ¡) to the "·" (On) position to use the subwoofer. The SCS 140 subwoofer will automatically turn itself on or go into standby (sleep) mode when left in the standby mode ("Auto/On" switch TM in the "Auto" position). When your receiver or amplifier is off, or is not sending program material to the subwoofer, the subwoofer will be in standby mode. When the subwoofer senses an audio signal, it will automatically turn itself on. If the subwoofer does not sense a signal after approximately twenty minutes, it will automatically go into standby mode. When the "Auto/On" switch TM is switched to the "On" position, the subwoofer will remain on, whether or not program material is playing. If you will be away from home for an extended period of time, or if the subwoofer will not be used, switch the Master Power switch ¡ to the Off position.

If there is no sound from the center speaker: · Check all wires and connections between receiver/ amplifier and speaker. Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured. · If your receiver/processor is set in Dolby Pro Logic mode, make sure the center speaker is not in phantom mode. · If your receiver/processor is set in Dolby Digital or DTS® mode, make sure the receiver/processor is configured so that the center speaker is enabled. If the system plays at low volumes but shuts off as volume is increased: · Check all wires and connections between receiver/ amplifier and speakers. Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured. · If more than one pair of main speakers is being used, check the minimum impedance requirements of your receiver/amplifier. If there is low (or no) bass output: · Make sure the connections to the left and right "Speaker Inputs" have the correct polarity (+ and ­). · Make sure the subwoofer is plugged into an active electrical outlet. · Make sure the powered subwoofer is plugged in and switched on. · In Dolby Digital or DTS® modes, make sure your receiver/processor is configured so that the subwoofer and LFE output are enabled.
