SERVICE MANUAL

SAFETY INFORMATION
Warning
Any person performing service of this unit will be exposed to
hazardous voltages and the risk of electric shock. It is
assumed that any person who removes the amplifier from
this cabinet has been properly trained in protecting against
avoidable injury and shock. Therefore, any service
procedures are to be performed by qualified service
personnel ONLY!
Caution
Before the amplifier is plugged in, be sure its rated voltage
corresponds to the voltage of the AC power source to be
used. Incorrect voltage could cause damage to the
amplifier when the AC power cord is plugged in. Do not
exceed rated voltage by more than 10%: operation below
90% of rated voltage will cause poor performance or may
shut the unit off.
Leakage/Resistance Check
Before returning the unit to the customer, perform a leakage
or resistance test as follows:
Leakage Current. Connect the unit to its rated power
source. Using an ammeter, measure the current between
the neutral side of the AC supply and chassis ground of the
unit under test. if leakage current exceeds 0.5mA, the unit
is defective. Reverse the polarity of the AC supply and
repeat.
Resistance. Measure the resistance from either side of the
line cord to chassis ground. If it is less than 500k ohms, the
unit is defective.
WARNING! DO NOT return the unit to the customer if it fails
one of these tests until the problem is located and corrected.

PSW-D115 CONTROLS AND THEIR FUNCTION

OPERATION
Crossover Adjustments
High-Pass Control
If you hooked up your subwoofer as shown in Speaker
Connection 4 on page 9. you also have the capability of
adjusting the high-pass frequency. The High-Pass control
determines the frequency at which the main speaker will
start reproducing sounds. If your main speakers can
comfortably reproduce some low-frequency sounds, also
set this control to a lower frequency setting, between 50Hz –
100Hz. This will concentrate the subwoofer’s efforts to the
ultradeep bass sounds, while your main speakers continue
to reproduce the mid-bass information. If you are using
smaller bookshelf speakers that do not extend to the lower
bass frequencies, set the high-pass crossover control to a
higher setting, between 125Hz –180Hz. With this setting,
your main speakers will not have the burden of reproducing
any low-frequency sounds.
If you hooked up your subwoofer as shown in Speaker
Connection 1 on page 8, the high-pass frequency is fixed at
150Hz.
If you hooked up your subwoofer as shown in Speaker
Connection 2 or 3 on page 8 and 9, no high-pass control
adjustment can be made from the subwoofer. Unless you
receiver/amplifier incorporates a high-pass crossover, your
main speakers will continue to get a full-range signal.
Final adjustment and blending of the low-pass and
high-pass controls may evolve over several listening
sessions. A good starting point would be to set both the low-
and high-pass controls to the same frequency and adjust
from that point.
Low-Pass Control
The Low-Pass control determines the highest frequency at
which the subwoofer reproduces sounds. If your main
speakers can comfortably reproduce some low-frequency
sounds, set this control to a lower frequency setting,
between 50Hz –100Hz. This will concentrate the
subwoofer’s efforts on the ultradeep bass sounds required
by today’s films and music. If you are using smaller
bookshelf speakers that do not extend to the lower bass
frequencies, set the low-pass crossover control to a higher
setting, between 120Hz –180Hz.
Phase
Phase Control
The Phase Control determines whether the subwoofer
speaker’s piston-like action moves in and out with the main
speakers, 0°, or opposite the main speakers, 180°. There is
no correct or incorrect setting. Proper phase adjustment
depends on several variables such as room size, subwoofer
placement and listener position. Adjust the phase switch to
maximize bass output at the listening position.
Remember, every system, room and listener is different.
There are no right or wrong settings; any setting you choose
will result in excellent performance. Should you decide to
fine-tune your system for optimum performance, be patient
and trust your ears. It will be worth the effort involved to fully
“tweak”your system.

SPEAKER CONNECTIONS
1) If your receiver/amplifier has no
subwoofer outputs or preamp outputs
for the left, center and right channels.
See Figure 1.
2) If your receiver/amplifier has
subwoofer outputs or preamp output
jacks for the left, center and right
channels, or left and right only. See
Figure 2.
If your receiver/amplifier has a single
(mono) subwoofer output or LFE
output, you may connect the output
to either the Left or Right line-level
input on the subwoofer. However, to
maximize the subwoofer's
performance, we recommend that
you use a “Y”-connector (not
included). Plug the single male end
of the “Y”-connector into the
receiver/amplifier, and connect each
of the 2 female connectors to an
RCA-type interconnect cable. Then
connect the 2 interconnect cables to
the Left and Right line-level inputs on
the PSW-D115.

3) If your receiver/processor contains
Dolby* Digital or DTSÒsurround processing
technology, then connect the subwoofer or
LFE output from your receiver/processor to
the Center line-level input as shown. Set the
“Low-Pass”control to the 180Hz position.
When hooked up using this method, all of
the crossover and level adjustments are
controlled through the receiver/processor.
4) If your receiver/amplifier has preamp
output jacks and main input jacks for the left
and right channels or you have a separate
pre-amp/ processor and power amplifier.
See Figure 4.
This method of hookup can offer the highest
level of performance for your complete
loudspeaker system. The PSW-D115
incorporates a variable high-pass crossover
in addition to a variable low-pass crossover.
When hooked up as shown, the subwoofer
will limit the low-frequency information that is
returned to your receiver/amplifier. Your
receiver/ amplifier does not need to waste
valuable power reproducing the low
frequencies. In addition, since no
low-frequency information is being sent to
your main loudspeakers, they are able to
reproduce mid and high frequencies with
greater clarity

Amplifier/Subwoofer PSW-D115

SERVICE BULLETIN JBL9903 - APRIL 1999
To:All JBL Service Centers This is considered a Minor repair
Models: PSW-D115
Subject: Check Solder Joints in Event of Failure
Some performance related complaints in the PSW-D115 powered Subwoofers may be caused by cold solder
connections between the 28 pins of the Power Amp Module and the main circuit board. When troubleshooting,
failure to check these joints can result in erroneous conclusions or wasted time.
In the event you receive a PSW-D115 Subwoofer with the complaints “Dead, or No Output, or
Motorboating (Oscillation)”, perform the steps listed below first before any further
troubleshooting takes place:
1) Unplug all cables, lay the subwoofer on a padded surface.
2) Remove all Philips screws around the outer perimeter of the amplifier faceplate.
3) Remove amplifier assembly; you should be able to remove the amplifier far enough out of the cabinet to
service it without removing the woofer wires.
4) Locate the Power Amp Module; it is the large gray component with a metal case. On the solder side of the
circuit board are the 28 soldered connections to the Module.
5) Regardless of whether you can visibly see breaks in any of the connections or not, carefully re-solder all 28
pin connections, adding 60/40 rosin core solder. Take care not “bridge”any connections on the board with
solder.
6) Inspect the solder joints to the main filter capacitors C1 and C2 on the main PCB and re-solder if needed.
7) Replace the amplifier assembly back into the cabinet; replace the screws.
8) Test the unit by applying a signal from a music source, adjust the volume to a moderate level and confirm
the original problem has been corrected.
