1. Read these instructions.
2. Keep these instructions.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with a dry cloth.
7. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
8. Do not install near any heat sources such as radiators, heat registers, stoves or other apparatus (including amplifiers) that produce heat.
9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety If the provided plug does not fit into your out­let, consult an electrician for replacement of the obsolete outlet.
10. Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles and the point where they exit from the apparatus.
Only use attachments/accessories

3. Unplug this apparatus during lightning
1 storms or when unused for long periods of time.
14. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is dam­aged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
5. Do not use attachments not recommended
1 by the product manufacturer, as they may cause hazards.
16. This product should be operated only from the type of power source indicated on the marking label. If you are not sure of the type of power supply to your home, consult your product dealer or local power company. For products intended to operate from bat­tery power or other sources, refer to the operating instructions.
17. If an outside antenna or cable system is connected to the product, be sure the antenna or cable system is grounded so as to provide some protection against voltage surges and built-up static charges. Article 810 of the National Electrical Code, ANSI/ NFPA 70, provides information with regard to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna-discharge unit, connection to grounding electrodes, and requirements for the grounding electrode. See Figure A.
18. An outside antenna system should not be located in the vicinity of overhead power lines or other electric light or power circuits, or where it can fall into such power lines or circuits. When installing an outside antenna system, extreme care should be taken to keep from touching such power lines or circuits, as
.
contact with them might be fatal.

PLACEMENT
Since the installation of a subwoofer can be somewhat more complicated than installation of full-range speakers, it is essential that you read this section very carefully prior to connecting the subwoofer to your system. Should you have questions relating to your installation, it is advisable to call either your dealer or JBL’s Customer Service Department for advice.
The performance of the subwoofer is directly related to its placement in the listening room and how you align the subwoofer with its satellite speakers. Setting the volume of the subwoofer in relationship to the left and right speakers is also of critical importance because it is essential that the subwoofer inte grate smoothly with the entire system. Setting the subwoofer’s volume level too high will result in overpowering, boomy bass. Setting the volume level too low will negate the benefits of the subwoofer.
Here are several additional facts on installation that may prove useful. It is generally believed by most audio authorities that low frequencies (below 125Hz) are nondirectional and, therefore, placement of a subwoofer within any listening room is not critical. While in theory it is true that the larger wave­lengths of extremely low frequencies are basically nondirectional, the fact is that, when installing a subwoofer within the limited confines of a room, reflec­tions, standing waves and absorptions generated within the room will strongly influence the performance of any subwoofer system. As a result, specific location of the subwoofer becomes important, and we strongly recommend that you experiment with placement before choosing a final location.
Placement will depend upon your room and the amount and quality of bass required (for example, whether or not your room permits placement of the subwoofer near either satellite).

OPERATION
Power On
Plug your subwoofer’s AC cord into a wall outlet. Do not use the outlets on the back of the receiver.
Initially set the Subwoofer-Level Control Turn on your sub by pressing the Power Switch
Turn on your entire audio system and start a CD or movie soundtrack at a moderate level.
Auto On/Standby
With the Power Switch ¶in the ON position, the Status LED •on the back panel will remain lit in red or green to indicate the On/Standby mode of the subwoofer.
RED = STANDBY (No signal detected, Amp Off) GREEN = ON (Signal detected, Amp On) The subwoofer will automatically enter the Standby mode after approximately
10 minutes when no signal is detected from your system. The subwoofer will then power ON instantly when a signal is detected. During periods of normal use, the Power Switch
for extended periods of nonoperation, e.g., when you are away on vacation.
Adjust Gain
Turn your Subwoofer-Level Control ¡ up to the halfway position. If no sound emanates from the subwoofer, check the AC-line cord and input cables. Are the connectorson the cables making proper contact? Is the AC plug connected to a “live” receptacle? Has the Power Switch been pressed to the “On” posi­tion? Once you have confirmed that the subwoofer is active, proceed by play­ing a CD, record or cassette. Use a selection that has ample bass information.
Set the overall volume control of the preamplifier or stereo to a comfortable level. Adjust the Subwoofer-Level Control ¡ until you obtain a pleasing blend of bass. Bass response should not overpower the room but rather be adjusted so there is a harmonious blend across the entire musical range. Many users have a tendency to set the subwoofer volume too loud, adhering to the belief that a subwoofer is there to produce lots of bass. This is not entirely true. A subwoofer is there to enhance bass, extending the response of the entire sys­tem so the bass can be felt as well as heard. However, overall balance must be maintained or the music will not sound natural. An experienced listener will set the volume of the subwoofer so its impact on bass response is always there but never obtrusive.

on the rear panel.
MAINTENANCE AND SERVICE
The enclosure may be cleaned using a soft cloth to remove fingerprints or to wipe off dust.
The grille may be gently vacuumed. Stains may be removed with an aerosol cleaner, following its instructions. Do not use any solvents on the grille.
All wiring connections should be inspected and cleaned or remade periodically. The frequency of maintenance depends on the metals involved in the connections, atmospheric conditions and other factors, but once per year is the minimum.
If a problem occurs, make sure that all connections are properly made and clean. If a problem exists in one loudspeaker, reverse the connection wires to the left and right system. If the problem remains in the same speaker, then the fault is with the loudspeaker. If the problem appears in the opposite speaker, the cause is in another component or cable. In the event that your subwoofer ever needs service, contact your local JBL dealer or visit www.jbl.com for a service center near you.
Phase Contr
The Phase Switch £ determines whether the subwoofer speaker’s pistonlike action moves in and out with the main speakers, 0˚, or opposite the main speakers, 180˚. Proper phase adjustment depends on several variables such as room size, subwoofer placement and listener position. Adjust the phase switch to maximize bass output at the listening position.
Crossover Adjustment
The Crossover Adjustment Control ¢ determines the highest frequency which the subwoofer reproduces sounds. If your main speakers can comfortably reproducesome low-frequency sounds, set this control to a lower frequency setting, between 50Hz efforts on the ultradeep bass sounds required by today’ If you are using smaller bookshelf speakers that do not extend to the lower bass frequencies, set the Crossover Adjustment control to a higher setting, between 120Hz and 150Hz.
NOTE: This control will have no effect if the LFE/Normal Selector ™ is set to LFE. If you have a Dolby Digital or DTS processor/receiver, the Low-Pass Frequency is set by the processor/receiver. Consult your owner’s manual to learn how to view or change this setting.
