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
1. Power LED - Will illuminate when the unit is turned on with the main power switch. This light will be RED when the unit is plugged in and not receiving a signal; when the PSW-D115 receives a signal, the light will cycle to
GREEN. If no signal is received after 10 – 15 minutes the light will cycle back to RED (standby) until a signal is present again.
2. Power Switch - Main Power Switch to the
PSW-D115; turn ON to energize the subwoofer. Under normal operation, Power Switch may be left ON to utilize the Auto ON/OFF feature. For extended periods of non-use, or vacations, it is recommended that the
PSW-D115's Power Switch be turned OFF.
3. Level Control - The subwoofer Level Control, adjusts the volume of the subwoofer relative to the rest of the system.
4. Video Contour - The subwoofer Video Contour
Control, optimizes the subwoofer's performance for movie listening. When the video-contour switch is “on” the subwoofer's performance is tailored to deliver the impact and excitement of today's movies. The green LED will illuminate when the video-contour switch is on.
5. Speaker In Jacks - Main Input connection to subwoofer when line level, subwoofer, or pre-amp output connectors are not available, or when a high pass filter
(set at 150Hz) to main loudspeakers is desired through the Speaker Output Jacks.
6. Speaker Out Jacks - Connected to main loudspeakers when the Speaker Input Jacks are used.
7. Phase Switch - Changes the subwoofer's output to be in phase or 180 degrees out of phase with the program material.
8. Line Input - Main Input connection to subwoofer
(preferred).
9. Direct In - If you will be connecting the PSW-D115 to a receiver/processor containing a Dolby Digital or DTS surround technology, use this single RCA connection.
See the owner's manual for complete instructions.
10. Line Output - When using the Line-Level Input jacks, these are connected to an external power amplifier or receiver to power the main loudspeakers with a high pass filter if desired.
11. Direct Out - This allows you to connect more than one PSW-D115 together; connect this output jack to the
Direct input jack on the second subwoofer.
12. High Pass Control - Controls the roll-off point of the lowest frequency produced at the High Pass Output
Jacks.
13. Low Pass Control - Controls the roll-off point of the highest frequency the subwoofer will produce.

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 lowand 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.
OPERATION
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.

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.

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

SERVICE BULLETIN JBL9903 - APRIL 1999
To:All JBL Service Centers
Models: PSW-D115
This is considered a Minor repair
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.

NOTE: THE FOLLOWING PROCEDURES MUST BE FOLLOWED
WHEN INSTALLING NEW S53AMI/S64AMI AMP MODULES:
FAILURE TO FOLLOW ONE OR MORE OF THESE STEPS MAY
RESULT IN THE INSTANT DESTRUCTION OF THE MODULE WHEN
POWERED UP.
1)
2)
3)
4)
5)
Align white indent marker on Amp Module with indent marker on main
PCB; alternately observe position of label on the top of the module; incorrectly replacing the Module 180 in the PCB slot will result in its destruction.
All AC powered test instruments (meters, oscilloscopes, etc.) must have a floating ground, i.e. be connected to an isolation transformer.
Align and position the Amp Module before soldering.
Attach the amp Module with the mounting screws powering up.
before soldering
Use only rosin-core or non-acid core solder; thoroughly de-flux the surfaces after soldering.
or
If the new S53AMI/S64AMI Amp Module has larger mounting hole(s) in the case, and the stock screws no longer will fit, and screws of the proper type cannot be obtained locally order:
(2) part# 60301S (screws)
