SPEAKER PLACEMENTProper placement of the speak-ers is an important step inobtaining the most realisticsoundstage possible. Theserecommendations are for theoptimum placement of the loud-

speakers. Use these placementrecommendations as a guide.Slight variations will not dimin-ish your listening pleasure.

All of the Northridge E Seriesloudspeakers referred to in thisguide are video-shielded andcan safely be placed near atelevision.

CONNECTION TIPS

Speakers and electronics termi-nals have corresponding posi-tive (+) and negative () termi-nals. It is important to connectboth speakers identically: posi-tive (+) on the speaker to posi-tive (+) on the amplifier andnegative () on the speaker tonegative () on the amplifier.Wiring out of phase results in thin sound, weak bass and a poor stereo image. With the advent of multichannelsurround sound systems, con-necting all of the speakers inyour system with the correctpolarity remains as important asever in order to preserve theproper ambience and direction-

ality of the program material.To use the binding-post speakerterminals, unscrew the coloredcollar until the pass-throughhole in the center post is visibleunder the collar. Insert the bareend of the wire through thishole; then screw the collardown until the connection istight. The hole in the center of eachcollar is intended for use withbanana-type connectors. Tocomply with European CE certification, these holes areblocked with plastic inserts atthe point of manufacture.To usebanana-type connectorsrequires the removal of theinserts. Do not remove theseinserts if you are using theproduct in an area covered bythe European CE certification.

TROUBLESHOOTINGIf there is no sound from anyof the speakers:

Check that receiver/amplifieris on and that a source is playing. Review proper operation ofyour receiver/amplifier.If there is no sound comingfrom one speaker:

Check the Balance controlon your receiver/amplifier. Check all wires and connec-tions between receiver/ampli-fier and speakers. Make sure nowires are touching other wiresor terminals and creating ashort circuit. Make sure all wires are con-nected. Make sure none of thespeaker wires are frayed, cut orpunctured. In Dolby* Digital or DTSmode, make sure that thereceiver/processor is config-ured so that the speaker inquestion is enabled. Turn off all electronics andswitch the speaker in questionwith one of the other speakersthat is working correctly. Turneverything back on, and deter-mine whether the problem hasfollowed the speakers, or hasremained in the same channel.If the problem is in the same

channel, the source of the prob-lem is most likely with yourreceiver or amplifier, and youshould consult the ownersmanual for that product for fur-ther information. If the problemhas followed the speaker, con-sult your dealer for furtherassistance or, if that is not pos-sible, visit www.jbl.com for further information.If the sys lays at low vol-umes but shuts off as vol-ume is increased:

Check all wires and connec-tions between receiver/ampli-fier and speakers. Make sure all wires are con-nected. Make sure none of thespeaker wires are frayed, cut orpunctured. If more than one pair of mainspeakers is being used, checkthe minimum impedancerequirements of your receiver/amplifier.If there is no (or low) bassoutput:

Make sure the polarities (+ and ) of the left and rightSpeaker Inputs are con-nected properly. Consider adding a poweredsubwoofer to your system foruse with digital .1 surroundformats.

If there is no sound from the surround speakers:

Check all wires and con-nections between receiver/amplifier and speakers. Makesure all wires are connected.Make sure none of the speakerwires are frayed, cut or punc-tured. Review proper operation ofyour receiver/amplifier and itssurround sound features. Make sure the movie or TVshow you are watching isrecorded in a surround soundmode. If it is not, check to seewhether your receiver/amplifierhas other surround modes youmay use. In Dolby Digital or DTS mode,make sure your receiver/pro-cessor is configured so that thesurround speakers are enabled. Review the operation of yourDVD player and the jacket ofyour DVD to make sure that theDVD features the desired DolbyDigital or DTS mode, and thatyou have properly selected thatmode using both the DVDplayers menu and the DVDdiscs menu.

NOTICE:Important Safety Notes

Proper selection of mountinghardware and installation of thewall brackets are the responsi-bility of the customer. This product is not intendedfor ceiling mounting.Two Number 8 round head orpan head screws should beused per loudspeaker. Thescrew head should be between5/16 inch (8mm) and 1/4 inch(6.3mm) in diameter, and thescrew should be at least 2inches (50mm) in length.When installing screws in anywall, always use properlyselected wall anchors. Attachtwo of the four self-adhesiverubber pads that came with theE10 loudspeaker to the back of

the enclosure in the two bottomcorners so that the cabinet isspaced evenly from the wall.Select a suitable mounting loca-tion on a wall. (The ceiling is nota suitable mounting location.) Drill two pilot holes, appropri-ately sized for the specific self-tapping screw or wall anchorthat you will be using. The holesshould be 8 inches (203mm)apart. See Figure 1. The holesshould be 3/4" (19mm) belowwhere you want the top of theenclosure to be positioned. Usea carpenters level to ensurethat the holes are even and thatthe speaker will mount on thelevel.Install the two screws intoeither a wooden wall stud oranchor, and tighten them until

the back of each screw head isabout 1/8 inch (3mm) from thewall. See Figure 2. Install theloudspeaker by slowly movingthe cabinet toward the screwsso that the screw heads clearthe larger circular portion of thetwo keyholes. Once both screwheads have entered the key-holes, the loudspeaker shouldgently be lowered onto thescrew shafts. Check that theloudspeaker is firmly lockedonto the screws by gentlypulling the speaker down andforward. Fig. 1 Fig. 2
