INTRODUCTION

Congratulations on choosing JBL
loudspeakers. Their highly
accurate, uncolored and balanced
sound character will greatly
increase your enjoyment of
recorded music. We build JBL
speakers with careful attention to
detail, using only the highest
quality materials. They will provide
many years of excellent
performance.

Our PS Series rivals the
performance of more expensive
powered subwoofers. It gives you
remarkably accurate and pleasing
sound reproduction.

m Amplified Subwoofer:

Your PS Series subwoofer has
both line-level and speaker­level stereo inputs for versatility
and ease of use. We've also
provided speaker output to let
you hook-up satellite
speakers. Adjustable level and
crossover points let you
balance the subwoofer with
your main speakers.

m High Polymer Laminate

/Polypropylene Woofers:
provide tight bass and well­defined sound reproduction
without harshness, stridency,
or listener fatigue.

m High Quality Active

Equalization Amplifier Circuitry:
Integrating the acoustic and
electronic systems into a single
enclosure enable JBL
engineers to employ an
equalizer circuit that extends
the bass response beyond the
limitations of a small enclosure.

m Acoustically Optimized

Enclosure: Optimized to
produce an extended and level
bass response.

m Magnetic Shielding: allows you

to place your subwoofer near
video monitors without creating
interference or distorting the
picture.

CONNECTIONS

CAUTION: Before making any
connections to your subwoofer,
make sure the power to your
entire system is OFF .

POWER

Plug the power cord into a
grounded wall outlet or the
accessory outlet on the back of
your amplifier/receiver.

INPUTS

Your PS subwoofer has both line­level and speaker-level input
connections. Review your
receiver/T.V./source amplifier
instruction manual to see which
outputs your equipment provides,
then follow the appropriate
instructions below.
"Line Input" - Use the RCA
(phono) input jacks labeled "Line
Input" when connecting from a
line-level device, such as a pre­amp, crossover, signal processor,
or when using any of the line-level
outputs on the rear of your
receiver/T.V./source amplifier. If
your receiver has a single RCA
output for sending the signal to the
subwoofer, you may connect this
output to the R or L input jack on
your PS subwoofer. Or, you may
connect it to both R & L input jacks
by using a "y" adapter. Many
stereo/ large screen T.V.'s have
stereo (R & L) RCA jacks for
sending the signal to external
audio equipment. Your subwoofer
connects to these using both the R
& L input jacks. (See Fig. 1).

"Speaker Level Input (from
amplifier)" - Use these inputs

when connecting to the speaker
out (speaker mains) of your
receiver/T.V./source amplifier.
Run speaker wires from the
speaker output terminals (usually
coded red and black) on the rear
of your receiver/T.V./source
amplifier to the red and black input
terminals labeled "Speaker Level
Input (from amplifier)" on the PS
subwoofer. (See Fig. 2)

Preparing the speaker level
hookup wire

Your JBL dealer can recommend
suitable cables, or you can buy
wire at most hardware stores.
High quality connectors and cable
offer consistent performance that
does not deteriorate over time.
We recommend #16 AWG two­conductor insulated wire as a
minimum size. If your PS
subwoofer is more than 30 feet
(10 m) from your receiver/T.V.
/source amplifier, use larger
diameter wire.

Making the speaker level
hookup

1. First measure the distance

from your receiver/T.V./source
amplifier to your PS subwoofer.

2. Next make two hookup wires
this length.

3. Strip off 3/8" of insulation from
both ends of each conductor
wire.

4. Twist each set of thin wires into
a tightly-bunched spiral.

5. Now find a visual difference
between the two conductors of
each molded pair of speaker
wire.
