CONNECTION TIPS

SPEAKER-LEVEL CONNECTIONS

Your S412P speakersshould be connected toyour receiver in two ways(at speaker level and linelevel) in order to achievethe best performance,especially when listeningto program materialrecorded in digital 5.1formats, such as Dolby** Digital and DTS.®Connect the left-front and

right-front speakerterminals on your receiveror amplifier to the 5-waybinding posts on the backof each S412P speaker.Remember to maintain thecorrect polarities (“+” to“+” and “–” to “–”). TheS412P uses a red bindingpost for “+” and black for“–”. These connectionswill provide full-range

sound to all fourtransducers, and youshould ALWAYS makethese connections. If your receiver oramplifier does not have aline-level subwooferoutput, then you do notneed to make any otherconnections, and youshould skip to the sectiontitled “Amplifier Controls.”

Speakers and electronicsterminals have corre-sponding (+) and (–)terminals. It is important toconnect both speakersidentically: (+) on thespeaker to (+) on the

amplifier and (–) on thespeaker to (–) on theamplifier. Wiring “out ofphase” results in thinsound, weak bass and apoor stereo image.

Each S412P speaker is alsoequipped with a line-levelLow-Frequency Effects(LFE/Subwoofer) input forsuperior performance withdigital 5.1 surroundformats. The .1 LFEchannel containsadditional low-frequencyinformation not found inthe left- and right-frontchannels. The LFE inputworks with the full-rangespeaker-level input toprovide the dynamics and

effects that your favoritefilmmakers intended. You will need to use a Y-Connector (not included)with one male connectorand two female connectorsto connect the line-levelsubwoofer output on yourreceiver/amplifier to theLFE/Subwoofer inputs onthe S412P speakers. Plugthe male connector intothe subwoofer output onyour receiver or amplifier,and connect each of the

two female connectors to extension RCA patchcords. Then plug eachpatch cord into theLFE/Subwoofer input of the left and right S412Pspeakers. Note: If yourreceiver has separate left and right line-levelsubwoofer (or LFE) outputjacks, you do not need touse a Y-Connector.

AMPLIFIER CONTROLS

LFE Level Control: Allowsyou to adjust the volume ofthe low-frequency effects/subwoofer channel to suityour room acoustics ortastes. However, it onlyaffects the LFE signal. Ifyou are not using the LFEinput, the LFE level controlwill not operate.

Configuring Your Receiver:You should choose the“Large” or “Wide” optionfor the left- and right-frontspeakers so that full low-frequency information willbe sent to the S412Pspeakers. Make sure thatyou also configure yourreceiver for “SubwooferOn” or “LFE On.” In thiscase, the LFE/Subwoofersignal will consist only ofthe .1 (bass) channel. TheLFE signal level can beadjusted by using the LFE level on the S412Pamplifier panel. For initialsetup, you should set thelevel controls on bothspeakers at minimum (full counterclockwiserotation). With 5.1 sourcematerial playing, advancethe level controls on eachspeaker slowly until thedesired amount of effectschannel is present. This is a rather subjectiveadjustment and should bemade using a variety ofprogram materials.

If you choose, you can usethe “Small” or “Narrow”setting on your receiver.In this case, all of theinformation below 80Hzwill be fed to the LFE/Subwoofer input on the

S412P. Now the levelcontrol operates through-out the entire bassspectrum below 80Hz, notjust within the .1 channelportion. This configuration isgenerally unnecessary but,in certain room-placementconditions, it allows greaterbass-level control.

Power Switches: The main“Power” switch is simplymarked “On” and “Off.”Turn this switch on tocommence operation ofthe powered amplifierafter you have plugged thepower cord into an ACoutlet. The second switchis labeled “On/Off” andhas two positions. Placingthe switch in the “Auto”position puts the amplifierin Standby mode. In thismode the speaker will beable to automaticallysense an incoming signal,which will trigger it to turnfully on. The speaker willalso automatically switchitself back into Standbymode after approximately10 to 15 minutes havepassed without its sensinga signal. We recommendthat you leave this switchin the “Auto” position formost applications. If youwill be away from home ornot using your speakersfor an extended period oftime, you should turn thespeakers off by using themain power switch. TheManual position will bypassthe auto-sensing featureand leave the amplifier onuntil turned off with themain switch or returned to

auto sensing by choosingthe auto position.

LED Indicators: When yourspeaker is turned on but isnot receiving a signal, theLEDs glow red to let youknow that your speaker isplugged in. When thespeaker is receiving asignal, the LEDs glowgreen. We have provided aconvenient “Green ‘On’LED” switch on the backpanel to allow you to shutoff the front LEDs shouldthey interfere with yourenjoyment of a movie. Thisswitch has no effect whenthe LEDs are in red mode.

T R O U B L E S H O O T I N GIf there is no sound from any of the speakers:• Check that receiver/amplifier is on and that asource is playing.• Review proper operationof your receiver/amplifier.

If there is no sound comingfrom one speaker:• Check the “Balance”control on yourreceiver/amplifier.• Check all wires andconnections betweenreceiver/amplifier and speakers.• Make sure all wires are connected. Make surenone of the speaker wiresare frayed, cut orpunctured.

If the system plays at lowvolumes but shuts off asvolume is increased:• Check all wires andconnections betweenreceiver/amplifier and speakers.• Make sure all wires areconnected. Make surenone of the speaker wires are frayed, cut orpunctured.• If more than one pair ofmain speakers is beingused, check the minimumimpedance requirements ofyour receiver/amplifier.

If there is no (or low) bassoutput:• Make sure the polarities (+ and –) of the left andright “Speaker Inputs” are connected properly.• Make sure that thespeaker is plugged into anactive electrical outlet andswitched on, and that thegreen LEDs are displayed.

If you used the LFE inputand there is no sound fromthe subwoofer:• Check that receiver/amplifier is on and that asource is playing.• Make sure that thespeaker is plugged into anactive electrical outlet.• Check all wires andconnections betweenreceiver/amplifier andspeakers.• Make sure all wires areconnected. Review the“Line-Level Connections”section on page 5 of thismanual and make sure thata single RCA patch cord is connected to eachloudspeaker from the Y-Connector plugged intothe receiver/amplifier’ssubwoofer output. Makesure none of the speakerwires are frayed, cut orpunctured.• Review proper operationof your receiver/amplifier,including making sure thatyou have configured yourreceiver so that the sub-woofer output is active.

If you are using the S412PLFE/Subwoofer input andthe bass level decreases(instead of increasing)when you turn the LFE/Subwoofer Level knobclockwise:• Recheck to make surethat your receiver oramplifier-speaker outputsare correctly connected tothe S412P speaker inputs(gold-plated binding posts),(+) to (+) and (–) to (–). TheS412P (+) terminal has a redstripe and is located on theright-hand side, below theletter “L” of the molded JBLlogo, when looking directly atthe back of the S412P.• If the wires are connectedproperly, the confusion maybe attributable to the designof your receiver/ amplifier.Your unit may have invertinginputs, which reverse thepolarity of the signalbetween the inputs andoutputs of the amplifier. Tocheck if this is the case,reverse the speaker con-nections for ALL S412Ps inyour system (and disconnectany other speakers in thesystem) so that thereceiver/amplifier’s (+)connector is connected toeach S412P’s (–) (blackstripe) speaker connector.If you do this and theS412Ps function properly(bass increases as you turnyour LFE/Subwoofer level-control knobs clockwise),your receiver/amp usesinverting inputs. This is nota problem. Simply connectall of the speakers in yoursystem the same way, withthe receiver or amplifier’s(+) terminal to the speaker’s(–) terminal, and the receiveror amplifier’s (–) terminal tothe speaker’s (+) terminal.
