(SCS 188 only) CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN CAUTION: To prevent electric shock, do not remove the grounding plug on the power cord, or use any plug or extension cord that does not have a grounding plug provided. Make certain that the AC outlet is properly grounded. Do not use an adapter plug with this product. The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. 2 SPEAKER PLACEMENT Front Speakers Center Channel Speaker 0 ­ 0.6m (0 ­ 2 ft.) Subwoofer Surround Speakers 150-180 cm 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. 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 placed on a wall behind the listening position, facing forward. The surround back speaker (in SCS 188 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 main program 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. 3 MOUNTING OPTIONS Satellites and Surrounds On shelves. On the wall. Wall brackets are included. On optional stands. Wall-Mounting The customer is responsible for proper selection and use of mounting hardware, available through hardware stores, to properly and safely wall-mount the speakers. 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. 4 Dolby* Pro Logic* (Non-Digital) ­ Speaker Level (SCS 178 only) 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 only has one subwoofer output jack, then you will need to use a Yconnector (not included). Plug the male end of the Yconnector into your receiver or amplifier's subwoofer output 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 subwoofer. Connect each speaker to the corresponding speaker terminals on your receiver or amplifier.

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 surroundsound 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. O P E R AT I O N Press the Master Power Switch (marked Power ¡) to the ON position to use the subwoofer. 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. 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. PHASE The Phase Control TM determines whether the subwoofer's pistonlike action moves in and out in phase with the main speakers or opposite the main speakers. This is adjusted by pressing the button to the 0°, or 180° position. The 0° position of the phase button plays the bass signal in phase with the main speakers. The 180° position plays the bass signal 180º, or out of phase with the main speakers. Proper phase adjustment depends on several variables such as subwoofer placement and listener position. Adjust the phase switch to optimize bass output at the listening position. Every system, room and listener is different. There are no right or wrong settings. This switch offers the added flexibility to adjust your subwoofer for optimum performance for your specific listening conditions without having to move your speakers. If at some time in the future you happen to rearrange your listening room, and move your speakers, you should experiment with the phase switch in both positions, and leave it in the position that optimizes bass performance for your taste. ¢ ¡ £ TM HIGH LEVEL +L­ ­R+ OUT IN LINE LEVEL IN LFE L R 0° PHASE 180° IMPORTANT: CONNECT STRIPED WIRE TO RED (+ ) SPEAKER TERMINAL.
