JBL SERIES LOUDSPEAKERS INSTRUCTION MANUAL
lntroduction
l) High output levels. This means that modest amplifiers or receivers will be able to produce acoustical levels normally associated with amplifiers with substantially more iated power.
2) Smooth, extended response. The JBL Series 12 mm pure titanium dome tweeter, polymer laminated cone drivers and carefully designed dividing network deliver clear, crisp, quality sound.
3) Accurate time/phase response. Speakers in the JBL Series exhibit the same precise "tum-on, tum-offl' characteristics of JBL's larger home and studio loudspeaker systems. This means more accurate realization of the high frequency detail in today's digital recordings.
Congratulations on choosing JBL loudspeakers. Their highly accurate, uncolored and balanced sound character will greatly increase your enjoyment of recorded music. JBL speakers ae built with careful attention to detail, using only the highest quality materials. They will provide many years of excellent performance.
The JBL Series is the result ofconcentrated efforts to combine traditional JBL performance values with elegant contemporary appearance at affordable prices. Some ofthe engineering features of the JBL Series are:
4) Accurate stereo imaging. The in-line component afrays on the baffle ensure the best possible stereo imaging for listeners both on axis and off.

Placement
For the best stereo reproduction, the two loudspeaker systems should be placed an equal distance from your listening position and separated so that the angle between them, at the listening position, is between 40 and 60 degrees (see Fig. 1). For example, if your listening position is 8 to 12 feet (2.5 to 4.5 m) from each speaker, the two systems should be about 8 feet (2.5 m) apart. Placing the loudspeakers in comers or against a wall will result in the strongest (but.not necessarily the most aocurate), bass. Compact systems will also benefit from placement on stands or shelves. For the best stereo imaging, we recommend that the systems be placed so that the high frequency transducers are as close as possible to the ear level of a seated
Iistener. Every room is different-and
there ae.different tastes. hesitate to experiment on your own.

Connections
To connect the loudspeaker systems to the receiver or amplifier, use two:' conductor insulated wire. Your JBL dealer'ca recommend suitable cables; or you can buy wire at most hardware stores. We recommend #18 AWG (1 mm diameter) wire as a minimum size. If your speakers are more than 30 feet (10 m) from your receiver or amplifier,
use larger diameter wire. Connections are made at the terminals located on the back of the loudspeaker.system, near the bottom edge. The terminals accept bare wire or banana plugs, either of which will
The black terminal on the loudspeaker should be connected to the black or (-) loudspeaker connection terminal on the receiver or amplifier.. .Connecting the loudspeakers in this manner ensures that they will be in phase; that is, work together rather than in opposition. Connecting the loudspeakers out ofphase will not damage them, but will result in less bass and poor imaging. Most twoconductor 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 (Fig. 2).
provide easy, secure connections. To
prepare the wire, strip approximately U}-inch(l3 mm)of insulation. Each conductor is made up of fine strands of wire; twist the strands together. Push down on the button below the terminal and insert the wire through the hole (see Fig. 2). For each channel, the red terminal on the loudspeaker should be connected to the red or (+) loudspeaker connection terminal on the receiver or amplifier.

General Care
The grille is held in place by pins near the edges. To remove the grille, grasp it by both top and bottom edges and pull gently. To replace the grille, reposition it carefully and press gently at the comers. Do not push on the center area ofthe
grille.
The Ioudspeaker enclosure may be cleaned with a slightly damp cloth. 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.
Seruice
Should your loudspeaker ever need service, retum it to the JBL dealer from
whom it was purchased. If for some reason this is impractical, write directly to
the JBL Customer Service Deparnent, describing the problem as fully as possible. Do not retum products to the JBL factory without prior authorization.
