Frequently Asked Questions - LX2000 HP

What is the ideal placement for the LX2000 center speaker?

Place the speaker directly above or below the TV, aligning the front faces. Avoid corners and walls for better sound quality.

How do I connect the LX2000 speaker to my amplifier?

Use cables with a minimum cross-section of 1.5 mm² for lengths up to 5 m. Respect polarity: red terminal (+) on speaker to red terminal (+) on amp, and black terminal (-) to black terminal (-).

Can I bi-wire the LX2000 speaker?

Yes, remove the metal jumpers between the High and Low inputs, then connect two separate cables from the amplifier. This improves resolution and dynamics.

Why should I avoid an amplifier with too low power?

An underpowered amp saturates more easily, creating distortions that send high-frequency signals to the tweeter, risking damage. Choose an amp with power headroom.

How do I maintain the LX2000 speaker?

Dust the cabinet with a soft dry cloth. For the grille, use a low-power vacuum cleaner. Never use solvents, waxes, or furniture cleaners.

Is the LX2000 speaker protected against electromagnetic interference?

Yes, it has electromagnetic interference shielding, allowing it to be placed near a TV without disturbance.

What is the ideal distance between the front speakers and the listening position?

For optimal stereo imaging, place the speakers at equal distance from your listening position, with an angle of 40 to 60 degrees between them.

How do I install the decoupling spikes (if supplied)?

Turn the speaker over, screw a nut onto each spike, insert them into the threaded holes, adjust the height and tighten the nuts. They isolate the speaker from floor vibrations.

What should I do if the sound seems diffuse or lacks bass?

Check cable polarity: wires must be in phase (red with red, black with black). Polarity reversal weakens bass and sound localization.

Where can I find spare parts or have the speaker repaired?

Contact your JBL dealer or local distributor. Do not attempt to repair yourself; bring the speaker to a professional.

USER MANUAL LX2000 HP

JBL LX SERIES INSTRUCTION MANUAL

Congratulations on choosing JBL LX Series loudspeakers.

JBL LX series loudspeakers are designed using the technologies that have made JBL the world's most famous brand of loudspeakers.

Wherever loudspeakers are important, integral parts of musical performances - in opera houses, in football stadiums or at rock concerts - JBL is the loudspeaker brand of choice.

By using only the best available materials and devoting careful attention to details, JBL is certain that your JBL speakers will provide many years of excellent performance.

The instructions in this manual will help you realize the full potential of your loudspeakers.

PLACEMENT

JBL LX Series loudspeakers are designed to produce the best possible sound when located at some distance from walls and corners. Approximately 1m is preferable. Placement in corners or close to walls will increase the amount of bass, but not necessarily the quality of the bass. If such placement is unavoidable it is recommended that you use the tone controls on your amplifier or receiver to reduce the bass.

The bookshelf-size loudspeakers should not be placed on the floor, but will greatly benefit from placement on an open, rigid stand 35-50 cm high, which will place the high frequency unit at ear level, which is important for the creation of the best possible stereo image. Placement of the speaker on a high quality stand will improve the accuracy of the bass, which again will lead to the most dynamic, expressive reproduction.

We strongly advise that you consult your JBL dealer for advice and demonstration.

Should you want to mount your JBL LX speaker on the wall, it is recommended to use a strong bracket. A distance of 2-4 cm from the wall will allow the rear panel mounted reflex port to work, while complete closing of the port will reduce the deepest bass.

For the best stereo image the two loudspeakers in the stereo system should be placed at the same distance from your listening position, and separated by an angle of 40^ to 60^ (see illustration). For example, if your listening position is 2.4 - 3.6m from each speaker, the two speakers should be 2 - 2.4m apart.

Since every room is different, and since room acoustics are very important to the overall sound, we strongly recommend that you experiment to find the placement that gives you the most pleasing results.

INSTALLATION OF SPIKES (LX2003, 2004 and 2005)

Spikes isolate the speaker from floor vibrations. To install the spikes, follow these directions:

1. Turn the speaker upside down with the bottom of the enclosure facing upwards.
2. Thread a nut onto each spike until the nut reaches the unthreaded section.
3. Screw the spikes into the threaded mounting sockets.
4. Adjust the spikes so they all are at the same height, then tighten the nuts to prevent the spikes from changing height, or from rocking side to side.

CONNECTIONS

NOTE: LX2004 and LX2005 have dual pairs of gold-plated terminals. For normal connection with a single run of loudspeaker cable, the metal bars between the High and Low inputs MUST be in place. Connect cable only to the inputs marked High. For separate cable connections to the Low and High inputs, see next section BI-WIRING. Connect the loudspeakers to your amplifier or receiver using two-conductor insulated wire. We recommend 1.5mm^2 wire as a minimum size for cable runs of up to 5m . If your loudspeakers have to be placed at greater distance from your amplifier or receiver you should use heavier wire. Too thin wire or too long wire runs can result in the sound from

the loudspeaker being different than intended, but will not do any harm. We recommend that you consult your dealer, who will be happy to assist you in this matter.

For each channel, the red terminal on the loudspeaker should be connected to the red (+) loudspeaker terminal on the amplifier or receiver, and the black terminal on the loudspeaker to the black (-) loudspeaker terminal on the amplifier or receiver. Connecting the loudspeakers in this manner ensures that they will have the same polarity ("in phase"). Connecting the loudspeakers with different polarity will not damage them, but will result in less bass and a poor stereo image. This can be determined by listening to a solo voice: if the voice can be located in the space between the two loudspeakers, the speakers are connected with the same polarity. If not, the voice will sound diffuse and be difficult to place in the space.

Most two-conductor wire is color-coded or has a ridge on one of its insulating jackets, so that you can easily identify which wire is connected to which terminal.

When connecting more than one pair of loudspeakers to an amplifier or receiver consult your dealer or amplifier manufacturer to ensure that the resulting load can be handled safely.

BI-WIRING

LX2004 and LX2005 have dual pairs of gold-plated terminals and can be bi-wired. Before bi-wiring, ALWAYS remove the metal bars between the High and Low inputs. Bi-wiring will improve resolution and dynamics. For even greater improvement, you may use two amplifiers (bi-amping).

DANGER: LOW POWER

Generally, loudspeakers can withstand a great deal of power, as long as the signal is undistorted. You can safely use a power amplifier with a power rating greater than the loud-speaker's recommended power, as long as the amplifier is not driven beyond its limits.

When amplifiers are overdriven, they "clip" the signal, creating distortion which appears as a high frequency signal. These high frequency signals are directed to the high frequency transducer by the crossover network, thereby creating a dangerous condition for the smallest driver in the loudspeaker system.

The smaller the amplifier you use, the greater the danger of overdriving the amp, and consequently the greater the potential danger to the high frequency transducer.

Excessive boost of the tone controls of the amplifier or receiver can also aggravate the situation.

Always use an amplifier or receiver that will make your LX loudspeakers play reasonably loud and at the same time sound clean and undistorted.

LX2000 CENTER CHANNEL

For surround sound systems, the JBL LX Series includes a dedicated center channel loudspeaker. LX2000 Center is magnetically shielded for safe use near the picture tube and should be placed directly on top of or beneath the television set. The front edge of LX2000 Center should be on a line with the front edge of the television. LX2000 Center must be connected in phase to the amplifier/receiver, i.e. plus-to-plus and minus-to-minus, exactly like the left and right front loudspeakers.

GENERAL CARE

JBL LX Series loudspeaker systems are constructed of high quality MDF-board, superior to solid wood in its acoustic properties. They are built to give many years of trouble-free service, and do not require special attention.

Occasional dusting with a clean, soft cloth will maintain the original beauty of the finish. Furniture waxes, polishes or cleaners are not recommended.

The grille may be gently vacuumed, and stains can be removed with an aerosol cleaner, following the manufacturer's instructions. Never use any solvents to clean any part of the system.

SERVICE

Should your JBL LX Series loudspeaker ever need service, return it to the JBL dealer from whom it was purchased. If for some reason this is impractical, contact your local JBL distributor.

This loudspeaker conforms to all the relevant standards in the EMC Directive (89/336/EEC)
