[. . . ] 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 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 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. SCS SATPair 178 speakers are perfect for bringing music to additional rooms in your home. If your receiver or amplifier is equipped with A/B speaker switching, simply connect the pair of speakers to the unused pair of speaker terminals on your receiver, following the directions in the Speaker Connections section. If you plan on playing both pairs of speakers simultaneously, check with the manufacturer of your receiver or amplifier to find out whether that use is recommended. 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 It is important to connect both 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. Stereo If you are using the JBL SCS SATPair178 in a stereo system, connect them to the Left and Right speaker outputs of your amplifier/receiver. Surround If you are using the JBL SCS SATPair178 as front or rear speakers in a surround system, connect them to the appropriate front or rear Left and Right outputs according to the instructions included with your surround amplifier/receiver. 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. 4 TROUBLESHOOTING If there is no sound from any of the speakers: · Check that receiver/amplifier is on and a source is playing. · Check all wires and connections between receiver/ amplifier and speakers. Make sure none of the speaker wires are frayed, cut or punctured. · Review proper operation of your receiver/amplifier. If there is no sound coming from one speaker: · Check the "Balance" control on your receiver/amplifier. · Check all wires and connections between receiver/ amplifier and speakers. Make sure none of the speaker wires are frayed, cut or punctured. · In Dolby Digital or DTS® modes, make sure that the receiver/processor is configured so that the speaker in question is enabled.
