7CONNECTION TIPSSPEAKER CONNECTIONSSeparate and strip theends of the speaker wire,as shown. The wires sup-plied with the system mayalready be stripped andtinned for easy insertion intothe speaker terminals. Youmay need to separate thetwo conductors further inorder to thread them throughthe shelf stand or floor standadapter. Speakers and elec-tronics terminals have corre-sponding (+) and (–) termi-nals. Most manufacturers ofspeakers and electronics,including JBL, use red todenote the (+) terminal andblack to denote the (–)terminal.The (+) lead of the speakerwire is noted with a stripe. Itis important to connect bothspeakers identically: (+) onthe speaker to (+) on theamplifier and (–) on thespeaker to (–) on the amplifier.Wiring “out of phase” resultsin thin sound, weak bass anda poor stereo image.With the advent of multi-channel surround soundsystems, connecting all ofthe speakers in your systemwith the correct polarityremains equally important inorder to preserve the properambience and directionalityof the program material.To connect the suppliedspeaker wires to the satelliteand center speaker termi-nals, press the red or blackplastic cap for the desiredterminal, insert the bare endof the wire into the holebelow the cap and releasethe cap. Gently tug on thewire to make sure that it isfully inserted.To use the binding-postspeaker terminals on thesubwoofer, unscrew thecolored collar until the pass-through hole in the centerpost is visible under thecollar. Insert the bare end ofthe wire through this hole;then screw the collar downuntil the connection is tight.The hole in the center of eachcollar is intended for usewith banana-type connectors.To comply with European CEcertification, these holes areblocked with plastic inserts atthe point of manufacture. Touse banana-type connectorsrequires the removal of theinserts.all four screws are driveninto the stud and not intodrywall. If the bracket needsto be mounted in drywall,the customer is responsiblefor selecting and usingappropriate wall anchorsand screws.Important Note: The MetalNut ¡ must be fully tight-ened against the SatelliteSpeaker ¶ as described inStep 5 before beginning Step7, in order to avoid damageto the Threaded Insert §.Such damage would not becovered under the warranty.Step 7: Holding the SatelliteSpeaker ¶ with both hands,reinsert the ball portion ofthe Ball and Shaft £ intothe Attachment Plate ¢.Step 8: Hand-tighten theMolded Nut ™ while posi-tioning the speaker for thedesired orientation. If theMolded Nut ™ is difficult totighten by hand, insert theMetal Bar ∞ into one of theholes in the outer edge ofthe Molded Nut ™ and usethe bar as a lever. Be carefulnot to cross-thread. Theswiveling ball enables you toaim the speaker to one sideor the other, or to tilt it up ordown. Stereo imaging maybe improved by aiming thefront speakers toward thelistening position, especiallyfor music selections.In Dolby® Digital and DTS®systems, it is best to aim allof the speakers (except thesubwoofer) toward the lis-tening position at about ear-level height. In systemswhere only analog surroundprocessing (such as DolbyPro Logic®) is available, itmay be preferable to aim thespeakers straight out fromthe wall to obtain a morediffuse sound.Step 9: Once the speaker’sorientation has been final-ized, insert the Metal Bar ∞into one of the holes in theouter edge of the MoldedNut ™ and tighten theMolded Nut ™ securely.Keep the Metal Bar ∞ ina safe place, in the eventthat you decide to adjustthe speaker’s orientationin the future.
