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 personal ONLY!
Caution
This unit does not have a power switch. Hazardous voltages are present within the unit whenever it is plugged in.
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. Note there is no power switch on this unit. When the power plug is plugged in, the unit is live.
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 0.5A, 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-D112/DPS-12 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-D112 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. Main Power Switch - Main Power Switch to the
PSW-D112/DPS-12; 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 subwoofer's Power Switch be turned OFF.
3. Level Control - The subwoofer Level Control,
(PSW-D112, located on the front panel, DPS-12, on the rear panel) adjusts the volume of the subwoofer relative to the rest of the system.
4. Video Contour - The subwoofer Video Contour
Control, (PSW-D112, located on the front panel) 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. Speak 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. 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.
10. Direct In - If you will be connecting the PSW-D112 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.
11. Direct Out - (rev0 version only) This connection allows you to connect more than one PSW-D112 or
DPS-12 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 Line Level 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.

3a) If your receiver/amplifier has a single
(mono) subwoofer output or LFE output, connect the output using a “Y”-connector
(not included) to both Left or Right line-level inputs on the subwoofer. Plug the single male end of the “Y” connector into the receiver/amplifier, and connect the 2 interconnect cables to the Left and Right line-level inputs on the subwoofer.
3b) If you will be connecting the
PSW-D112/DPS-12 to a receiver/processor containing a Dolby Digital or D.T.S. surround technology:
1. For the Rev0 version, connect the subwoofer or LFE output from your receiver/processor to the Center.
line-level input as shown in Figure 3b.
2. For the Rev1 version, (with no center channel input jack), connect the subwoofer or LFE output from your receiver/processor to EITHER Left or
Right line-level input jack with a single
RCA cable.
3. Set the “Low-Pass” control to the full clockwise 180Hz setting.
The connection labeled “Direct” (on Rev0 version of the subwoofer) is an output that allows you to connect several subwoofers, if your system contains more than one subwoofer.
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-D112/
DPS-12 incorporates a variable high-pass crossover in addition to a variable low-pass crossover. When hooked up as shown above, 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
This is considered a Minor repair Service Bulletin JBL9903 Rev1 - February 2001
To: All JBL Service Centers
Models: PSW-D110, PSW-D112, ARC SUB 8, ARC SUB 10
Subject: Check Solder Joints in Event of Failure
Some performance related complaints in the PSW-D110, PSW-D112, ARC SUB 8 or ARC SUB 10 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-D110, PSW-D112, ARC SUB 8 or ARC SUB 10 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.
IMPORTANT SERVICE NOTES: When testing the PSW-D, or ARC Series amplifier, a load must always be connected to the output terminals, whether the woofer, or a 4 to 8 ohm resistive load.
All AC powered test instruments (meters, oscilloscopes, etc.) must have a floating ground, i.e. be connected to an isolation transformer.

Service Bulletin JBL2001-02 - February 2001
To: All JBL Service Centers
Models: PSW-D112 rev0*, DPS-12, PSW-D115
Subject: Check Ribbon Cable Connection In Event Of Failure
Service Bulletin
This is considered a Minor repair
Some performance related complaints in the PSW-D or DPS Series powered Subwoofers may be caused by broken or cold solder connections in the ribbon cable connector between the premamp and main PCB.
When this condition occurs, it may also damage the Input Op-Amps U1/U2.
When troubleshooting, failure to check this connector and Input Op-Amps U1/U2 can result in erroneous conclusions or wasted time.
In the event you receive a PSW-D112*, DPS-12, or PSW-D115 Subwoofer with any of the complaints
“Dead, or No Output, or Motorboating (Oscillation)”, perform the steps listed below 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 other connecting wires.
4) Locate the ribbon cable connector between the premamp PCB and the main PCB. See illustration.
5) Desolder the connection on that cable where the cable attaches to the premamp PCB; to access, you may have to carefully remove or scrape adhesive from this area.
6) Cut approximately ½” of ribbon from the cable end, then strip enough of the insulator on each of the six conductors to allow re-connection. Take care not to damage the wire. Solder the cable end back onto the premamp PCB.
7) 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.
8) If not, troubleshoot Op-Amps U1 and U2 by standard methods; replace if defective:
Make sure plus/minus voltages are present on pins 4 and 11.
Make sure DC voltages are not present at output pins 1,7,8,14. (See schematic)
Apply a signal and confirm there is an output on pins 1,7,8,14. (See schematic)
9) Replace the amplifier assembly back into the cabinet; replace the screws.
IMPORTANT SERVICE NOTES: When testing the
PSW-D or DPS Series amplifier, a load must always be connected to the output terminals, whether the woofer, or a 4 to 8 ohm resistive load.
All AC powered test instruments (meters, oscilloscopes, etc.) must have a floating ground, i.e. be connected to an isolation transformer.
* Rev 0 of the PSW-D112 subwoofer is easily identified by the presence of Center channel Input and Output connectors

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)
(2) part# 60301N (nuts)
