INTRODUCTION  
Acoustically Optimized  
Enclosure: Optimized to  
produce an extended and level  
bass response.  
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 PSW Series rivals the  
performance of more expensive  
powered subwoofers. It gives you  
remarkably accurate and pleasing  
sound reproduction.  
Amplified Subwoofer:  
Your PSW 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.  
High Polymer Laminate  
Woofers: Provide tight bass  
and well-defined sound  
reproduction without  
harshness, stridency, or  
listener fatigue.  
High Quality Active

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 PSW subwoofer.  
(See Fig. 2)  
CAUTION: Before making any  
connections to your subwoofer,  
make sure the power to your  
entire system is OFF.  
AC POWER  
First make sure the Volume  
Control on the rear panel of your  
PSW Subwoofer is in the minimum  
position. Make all connections,  
then plug the AC cord into a wall  
socket.  
Preparing the speaker level  
hookup wire  
INPUTS  
Your PSW 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.  
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 PSW  
subwoofer is more than 30 feet  
(10 m) from your receiver/T.V./  
source amplifier, use larger  
diameter wire.  
"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  
Making the speaker  
level hookup  
1. First measure the distance  
from your receiver/T.V./source  
amplifier to your PSW  
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.  
receiver/T.V./source amplifier.  
If your receiver has a single  
RCA output for sending the  
signal to the subwoofer,  
connect it to both R & L input  
jacks by using a "y" adapter  
(not included).  
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)

the same procedure described  
under Speaker Level Input.  
Connect the red (+) terminal of the  
PSW 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)  
These differences can be a  
different color wire (copper or  
"silver"); a strand of yarn in one  
conductor; thin, raised ribs on one  
part of the outer insulation; or a  
printed "+" marking on one of the  
insulators. It doesn't matter which  
of the two strands of wire go to (+)  
and (–) on your receiver/T.V./  
source amplifier and PSW sub-  
woofer, 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 PSW subwoofer, and  
the black to the black or (–).  
Connecting the PSW subwoofer  
this way ensures that both

channel at the same time.  
OUTPUTS  
Your subwoofer has a speaker  
output terminal block to enable  
the signal to be sent to your main  
speakers or satellites. Your PSW  
subwoofer can use the signal from  
your receiver/T.V./source amplifier  
to produce the low bass while  
passing the unaltered signal  
source to the external speakers.

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  
Use the POLARITY switch to  
maintain proper acoustic  
summation with the main  
speakers. Listen to your PSW  
subwoofer and main speakers  
with the switch on "0˚", then listen  
to the same material with the  
switch on "180˚". Decide which  
way sounds better and leave the  
switch in this position. You should  
repeat this procedure if you move  
your PSW subwoofer to another  
part of the room.  
speakers (without much low end),  
you want the crossover frequency  
more toward the upper end  
(150 Hz) to fill in the sound your  
satellites can't reproduce. When  
using larger main speakers, a  
setting more towards the 90 Hz  
end gives a smoother transition  
from your PSW subwoofer to your  
main speakers. Experiment until  
you find a setting that meets your  
satisfaction.  
ALC PROTECTION CIRCUITRY  
Your PSW series amplifier has a  
built-in Automatic Level Control  
circuitry that comes on  
automatically when subjected to  
high input signal levels. It helps to  
protect the subwoofer driver from  
being damaged by accidental mis-  
use, assuring you of many years  
of excellent performance.  
Your PSW subwoofer turns itself  
off internally. For extended  
periods of non-use (i.e., vacations,  
etc.) you may wish to unplug the  
PSW subwoofer.  
GENERAL CARE  
Use a damp cloth for cleaning  
your PSW subwoofer cabinet.  
Do not use detergents or other  
cleaners.  
PLACEMENT CAUTION: Do  
not place your PSW 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 PSW 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.  
However, the closer the  
TROUBLESHOOTING / SERVICE  
Your PSW subwoofers should  
only be serviced by an  
authorized JBL repair station.  
Woofers are replaceable by  
repair station only. Do not  
remove the amplifier from the  
cabinet. There are no user-  
serviceable parts inside.  
Before seeking service for your  
PSW subwoofer, please recheck  
all connections as outlined in this  
manual. Verify that your AC wall  
power source is working properly  
by checking with another
