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.  
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.  
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.  
Acoustically Optimized  
Enclosure: Optimized to  
produce an extended and level  
bass response.  
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  
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 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  
output for sending the signal to the hookup  
subwoofer, you may connect this  
output to the R or L input jack on  
your PS subwoofer. Or, you may

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

subwoofer, just be sure to connect  
both left and right hookup wires  
identically. Push down on the  
button below the terminal and  
insert the wire through the hole.  
For each channel, connect the red  
terminal on the receiver/T.V.  
/source amplifier to the red or (+)  
loudspeaker connection terminal  
on the PS subwoofer, and the  
black to the black or (-).  
Connect the red (+) terminal of the  
PS subwoofer to the red (+)  
terminal of the external speaker,  
and the black (-) to black.  
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

the "Level" knob to add the  
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
