SPEAKER PLACEMENT
Proper placement of the speakers is an important step in obtaining the most realistic soundstage possible. These recommendations are for the optimal
The S412PII speaker features four rubber feet that enable it to be placed on a smooth surfaced floor, such as tile or hardwood. Four metal spikes are supplied for use when the speaker is to be placed on a carpeted surface to decouple the speaker from the floor and prevent unwanted damping.
placement of the loudspeakers. Use them as a guide. Slight variations will not diminish your listening pleasure.
To insert the spikes, gently lay the speaker on its side (not its front or back) on a soft, nonabrasive surface. Each spike screws into the threaded insert in the center of each rubber foot. Make sure all four spikes are screwed in completely for stability.
NEVER drag the speaker to move it, as this will damage the spikes, the feet and/or the wood cabinet itself. Always lift the speaker and carry it to its new location.
The S412PII loudspeakers are video-shielded and can safely be placed near a television.
CAUTION: Floor standing (tower) loudspeakers have a high center of gravity and may become unstable and tip over during earthquakes or if rocked, tipped or improperly positioned. If this is a concern, these speakers should be anchored to the wall behind them, using the same procedures and hardware customary for anchoring bookcases and wall units. Customer is responsible for proper installation and proper selection of hardware.
SPEAKER CONNECTIONS
CONNECTION TIPS
Speakers and electronics terminals have corresponding (+) and (–) terminals. 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.
To use the binding-post speaker terminals, unscrew the collar until the pass through hole in the center post is visible under the collar. Insert the bare end of the wire through this hole; then screw the collar down until the connection is tight. The hole in the center of each collar is intended for use with banana-type connectors.
SPEAKER-LEVEL CONNECTIONS
Your S412PII speakers should be connected to your receiver in two ways (at speaker level and line level) in order to achieve the best performance, especially when listening to program material recorded in digital formats, such as Dolby* Digital and DTS.®
Connect the left-front and right-front speaker terminals on your receiver or amplifier to the 5-way binding posts on the back of each S412PII speaker. Remember to maintain the correct polarities (“+” to “+” and “–” to “–”). The S412PII uses a red binding post for “+” and black for “–”. These connections will provide full-range sound to all four transducers, and you should ALWAYS make these connections.
If your receiver or amplifier does not have a line-level subwoofer output, then you do not need to make any other connections, and you should skip to the section titled “Amplifier Controls.”
LINE-LEVEL CONNECTIONS
Each S412PII speaker is also equipped with a line-level Low-Frequency Effects (LFE/Subwoofer) input for superior performance with digital surround formats. The .1 LFE channel contains additional low-frequency information not found in the left- and right-front channels. The LFE input works with the full-range speaker-level input to provide the dynamics and effects that your favorite filmmakers intended. You will need to use a Y-Connector (not included) with one male connector and two female connectors to connect the line-level subwoofer output on your receiver/amplifier to the LFE/Subwoofer inputs on the S412PII speakers. Plug the male connector into the subwoofer output on your receiver or amplifier, and connect each of the two female connectors to extension RCA patch cords.
Then plug each patch cord into the LFE/Subwoofer input of the left and right S412PII speakers. Note: If your receiver has separate left and right line- level subwoofer (or LFE) output jacks, you do not need to use a Y-Connector.
AMPLIFIER CONTROLS
LFE Level Control: Allows you to adjust the volume of the low-frequency effects/ subwoofer channel to suit your room acoustics or tastes. However, it only affects the LFE signal. If you are not using the LFE input, the LFE level control will not operate.
Configuring Your Receiver:
You should choose the “Large” or “Wide” option for the left- and right-front speakers so that full lowfrequency information will be sent to the S412PII speakers. Make sure that you also configure your receiver for “Subwoofer On” or “LFE On.” In this case, the
LFE/Subwoofer signal will consist only of the .1 (bass) channel. The LFE signal level can be adjusted by using the LFE level on the S412PII amplifier panel. For initial setup, you should set the level controls on both speakers at minimum (full counterclockwise rotation). With 5.1, 6.1 or 7.1 source material playing, advance the level controls on each speaker slowly until the desired amount of effects channel is present.
This is a rather subjective adjustment and should be made using a variety of program materials.
If you choose, you can use the “Small” or “Narrow” setting on your receiver.
In this case, all of the information below 80Hz will be fed to the LFE/
Subwoofer input on the S412PII. Now the level control operates throughout the entire bass spectrum below 80Hz, not just within the .1 channel portion. This configuration is generally unnecessary but, in certain room-placement conditions, it allows greater bass-level control.
Power Switches: The main “Power” switch is simply marked “On” and “Off.” Turn this switch on to commence operation of the powered amplifier after you have plugged the power cord into an AC outlet. The second switch is labeled “On/Off” and has two positions. Placing the switch in the “Auto” position puts the amplifier in Standby mode.
In this mode the speaker will be able to automatically sense an incoming signal, which will trigger it to turn fully on. The speaker will also automatically switch itself back into Standby mode after approximately 10 to 15 minutes have passed without its sensing a signal.
We recommend that you leave this switch in the “Auto” position for most applications. If you will be away from home or not using your speakers for an extended period of time, you should turn the speakers off by using the main power switch. The Manual position will bypass the auto-sensing feature and leave the amplifier on until turned off with the main switch or returned to auto sensing by choosing the auto position.

CAUTION
RISK OF ELECTRIC SHOCK DO NOT OPEN
“WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE.” “AVERTISSEMENT: POUR PRÉVENIR LES RISQUES D’INCENDIE OU DE CHOC ELECTRIQUE, EVITER D’EXPOSER CET APPAREIL A LA PLUIE OU A L’HUMIDITE.”
LED Indicators: When your speaker is turned on but is not receiving a signal, the LEDs on the front of the unit glow red to let you know that your speaker is plugged in. When the speaker is receiving a signal, the LEDs glow green. We have provided a convenient
“Green ‘On’ LED” switch on the back panel to allow you to shut off the front LEDs should they interfere with your enjoyment of a movie. This switch has no effect when the LEDs are in red mode.
TROUBLESHOOTING
If there is no sound from any of the speakers:
- Check that receiver/amplifier is on and that a source is playing.
- 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 all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured.
- Make sure no wires are touching other wires or terminals and creating a short circuit.
- 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.jbl.com for further information.
If the system plays at low volumes but shuts off as volume is increased:
- Check all wires and connections between receiver/ amplifier and speakers.
- Make sure all wires are connected. 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. If there is no (or low) bass output:
- Make sure the polarities (+ and –) of the left and right “Speaker Inputs” are connected properly.
- Make sure that the speaker is plugged into an active electrical outlet and switched on, and that the green LEDs are displayed.
- In Dolby Digital or DTS mode, make sure your receiver/ processor is configured so that the subwoofer and LFE output are enabled.
If you used the LFE input and there is no sound from the subwoofer:
- Check that receiver/amplifier is on and that a source is playing.
- Make sure that the speaker is plugged into an active electrical outlet and switched on, and that the green LEDs are displayed.
- Check all wires and connections between receiver/ amplifier and speakers.
- Make sure all wires are connected. Review the “LineLevel Connections” section on page 5 of this manual and make sure that a single RCA patch cord is connected to each loudspeaker from the Y-Connector plugged into the receiver/amplifier’s subwoofer output. Make sure none of the speaker wires are frayed, cut or punctured.
- In Dolby Digital or DTS mode, make sure your receiver/ processor is configured so that the subwoofer and LFE output are enabled.
If you are using the S412PII LFE/Subwoofer input and the bass level decreases (instead of increasing) when you turn the LFE/Subwoofer Level knob clockwise:
- Recheck to make sure that your receiver or amplifierspeaker outputs are correctly connected to the S412PII speaker inputs (gold-plated binding posts), (+) to (+) and (–) to (–). The S412PII (+) terminal has a red stripe and is located on the right-hand side, below the letter “L” of the molded JBL logo, when looking directly at the back of the S412PII.
- If the wires are connected properly, the confusion may be attributable to the design of your receiver/amplifier. Your unit may have inverting inputs, which reverse the polarity of the signal between the inputs and outputs of the amplifier. To check if this is the case, reverse the speaker connections for ALL S412PII’s in your system (and disconnect any other speakers in the system) so that the receiver/amplifier’s (+) connector is connected to each S412PII’s (–) (black stripe) speaker connector. If you do this and the S412PII’s function properly (bass increases as you turn your LFE/Subwoofer levelcontrol knobs clockwise), your receiver/amp uses inverting inputs. This is not a problem.
Simply connect all of thespeakers in your system the same way, with the receiver or amplifier’s (+) terminal to the speaker’s (–) terminal, and the receiver or amplifier’s (–) terminal to the speaker’s (+) terminal.
