[. . . ] 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. Two satellites for left/right front, surround, or surround back channels Two wall-mount brackets and eight screws High-Quality, 5-Way, Binding-Post Speaker Terminals Removable Cloth Grille Elegant Cabinet Features Built-In, 2-Position Tilt for Aiming Output Toward Listening Area Includes Wall-Mount Brackets and Speaker Cables Surround Back Speakers (7. 1-Channel System) In 7. 1-channel systems, place the side surround speakers slightly behind the listening position, as shown in the diagram to the left. The surround back speakers should be placed on the rear wall, facing forward, the same distance apart as the main front speakers. In 6. 1-channel systems, you may use a pair of HKS 2 speakers for the surround back speakers in place of a single rear center speaker. [. . . ] In 6. 1-channel systems, you may use a pair of HKS 2 speakers for the surround back speakers in place of a single rear center speaker. Using two speakers will provide a more diffuse surround effect, and will also increase the total sound output for the surround back channel without overworking any individual speaker. Place the two speakers on the rear wall the same distance apart as each speaker is from the listener, but at least four feet apart. 5 ­ 6 ft. Two 40' speaker cables for connection from receiver or amplifier to speakers Surround Back Speakers (6. 1-Channel System) (place at least 4 feet apart) 2 INTRODUCTION SPEAKER PLACEMENT 3 MOUNTING OPTIONS Wall-Mounting Attach the bracket to the wall. We strongly recommend that you position the speakers so that the mounting screws used connect directly to a wooden wall stud. If that is not possible, use optional wall anchors that are rated to support at least twenty-five pounds, and install them following the manufacturer's instructions carefully. You are responsible for proper selection and use of mounting hardware, available through hardware stores, to properly and safely wallmount the speakers. SPEAKER CONNECTIONS Connection Guide IMPORTANT NOTE: Before making speaker connections, be certain that your receiver or audio power amplifier is turned off and, preferably, unplugged from its AC power source. 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 Harman Kardon, use red to denote the (+) terminal and black for the (­) terminal. 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. Left Speaker + ­ Right Speaker + ­ The speakers may be placed on a shelf. They may be tilted upwards simply by tilting them back onto their sculpted surfaces. Left Right ­ + ­ + Front-, Surround- or Surround Back-Channel Receiver/Amplifier Output Configuring Your Receiver or Processor Many receivers and processors feature programmable bass-management capability, which allows the component to output the lowest frequencies (the bass information) exclusively to a separate subwoofer speaker, or to a main speaker that is capable of handling low frequencies, or sometimes to both. Make sure none of the speaker wires are frayed, cut or punctured, and that no wires are touching each other. · In Dolby Digital or DTS mode, make sure that the receiver/processor is configured so that the speaker in question is enabled. · In Dolby Digital or DTS mode, check the speaker and channel output levels and adjust if needed. · Turn off all electronics and switch the speaker in question with one of the other speakers that is working correctly. Turn everything back on, and determine whether the problem is in the same place: i. e. , the speaker that was working previously now has no sound and the speaker that was not working now sounds fine; or whether it has moved: i. e. , the speaker that was not working still has no sound and the speaker that was working is still fine. If the problem is in the same place, the source of the problem is most likely with your receiver or amplifier, and you should consult the owner's manual for that product for further information. If the problem has followed the speaker, consult your dealer for further assistance or, if that is not possible, visit our Web site at www. harmankardon. com for further information. · Check all wires and connections between receiver/amplifier and speakers. 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. [. . . ] 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. · Make sure the polarities (+ and ­) of the left and right speaker inputs are connected properly. · Consider adding a powered subwoofer to your system.
