JBL SERIES LOUDSPEAKERS INSTRUCTION MANUAL
lntroduction
Congratulations on choosing JBL
loudspeakers. Their highly accurate,
uncolored and balanced sound character
will greatly increase your enjoyment of
recorded music. JBL speakers a¡e built
with careful attention to detail, using only
the highest quality materials. They will
provide many years of excellent perform-
ance.
The JBL Series is the result ofconcen-
trated efforts to combine traditional JBL
performance values with elegant
contemporary appearance at affordable
prices. Some ofthe engineering features
of the JBL Series are:
l) High output levels. This means that
modest amplifiers or receivers will be
able to produce acoustical levels normally
associated with amplifiers with substan-
tially 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' charac-
teristics of JBL's larger home and studio
loudspeaker systems. This means more
accurate realization of the high frequency
detail in today's digital recordings.
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 a¡e.different tastes. Sodonrt .
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
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.
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 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 (Fig. 2).

iGeneral 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 manufac-
turer'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 DeparÍnent,
describing the problem as fully as
possible. Do not retum products to the
JBL factory without prior authorization.
