Ⅵ Amplified Subwoofer:
INTRODUCTION
Your PS Series subwoofer has
both line-level and speaker-
level 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.
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.
Ⅵ High Polymer Laminate
/Polypropylene Woofers:
provide tight bass and well-
defined sound reproduction
without harshness, stridency,
or listener fatigue.
Our PS Series rivals the
performance of more expensive
powered subwoofers. It gives you
remarkably accurate and pleasing
sound reproduction.
Ⅵ 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.
Ⅵ Acoustically Optimized
Enclosure: Optimized to
produce an extended and level
bass response.
Ⅵ Magnetic Shielding: allows you
to place your subwoofer near
video monitors without creating
interference or distorting the
picture.

CONNECTIONS
"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)
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 line-
level 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 pre-
amp, 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

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 two-
conductor 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

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 2. Next make two hookup wires
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).
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.

both left and right hookup wires
identically. Push down on the

Connect the red (+) terminal of the
PS subwoofer to the red (+)

Connecting the external speakers
this way ensures that they will be
in phase; that is, working together
not in opposition. Connecting the
speakers out of phase won't
damage them, but will result in
less bass and poor imaging. (See
Fig. 3).
Connecting the PS subwoofer this
way ensures that both channels
will be in phase; that is, working
together not in opposition.
NOTE: Connecting your satellite
speakers through your PS
subwoofer won't change their
impedance.
Your PS subwoofer will accept
stereo (left and right) inputs or a
mono input (hooking up to just the
left or right input) using either line
level or speaker level input.
LEVEL
NOTE: when first setting up
your PS subwoofer, set the
Level control counter-clockwise
to "Min" (minimum) before
turning power switch ON.
CAUTION: Never attach inputs
to both line level and speaker
level inputs of the same channel Turn power switch to On and use
at the same time.

appropriate amount of bass to
your main speaker output.
Increase the subwoofer level by
turning level knob clockwise until
you find a setting that is pleasing
to you.
OUTPUTS
Your subwoofer has a speaker
output terminal block to enable the
signal to be sent to your main
speakers or satellites. Your PS
subwoofer can use the signal from

CROSSOVER FREQUENCY
Use the crossover frequency knob
to adjust the upper end of the
subwoofer's frequency response.
The crossover control determines
the highest frequency your
subwoofer will reproduce. It allows
a seamless transition from
subwoofer to satellite speakers.
When using small satellite
speakers (without much low end),
you want the crossover frequency
more toward the upper end (200
Hz) to fill in the sound your
begins to play. The LED turns
green. After approximately 3
minutes of non-use (no signal
being received), your PS
subwoofer goes into the auto shut-
off mode. The LED turns RED to
signify this stand-by condition.
AMBER - The LED turns amber
briefly when the amplifier is in the
protection mode. This occurs
when the subwoofer power switch
is turned on while your
receiver/T.V. /source amplifier is
sending a signal to the PS
satellites can't reproduce. When
using larger main speakers, a
setting more towards the 50 Hz
end gives a smoother transition
from your PS subwoofer to your
main speakers. Experiment until
you find a setting that meets your
satisfaction.
subwoofer.
NOTE: When the amplifier is in
the stand-by mode it is effectively
turned off. The Red LED tells you
that the PS subwoofer is plugged
into the AC wall power with its
power switch turned on, but the
amplifier circuitry is not engaged.
You do not have to reach to the
back panel and turn the power
switch off after every use. Your PS
subwoofer turns itself off internally.
For extended periods of non-use
(ie, vacations, etc.) you may wish
to turn the PS subwoofer off using
the power switch.
MULTICOLOR LED INDICATOR
OPERATION
The LED on the front of the
enclosure signifies the following
operation states of the PS
subwoofer:
RED - When your PS subwoofer
isn't receiving a music or source
signal and the power switch is
turned on, the LED indicator turns
REDtelling you that the unit is
plugged in and ready for
operation. At this time, the
amplifier is in a "stand-by" mode,
effectively turned off and waiting
for a signal from the source
amplifier.
PLACEMENT - CAUTION: Do not
place your PS subwoofer next to
heaters, furnaces, or any other
heat sources. Be sure not to pinch
or compress the power cord.
Since the low frequencies
produced by your PS subwoofer
are non-directional, the placement
of your subwoofer is not critical.
You may place it under an end
table, next to the wall, next to T.V.,
anywhere you would like.
GREEN - When your PS
subwoofer picks up a source
signal, it turns on instantly and
