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.

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 lowand high-pass controls to the same frequency and adjust from that point.
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.
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.

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
Service Bulletin JBL9903 Rev1 - February 2001 To: All JBL Service Centers This is considered a Minor repair 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.

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

Troubleshooting tips and solutions to common service problems
For models: PSWD112 Rev1 only * PSWD115 TIP# JBLTT2004-02
Subject: PSWD112/115 WIRING TO REMOTE VOLUME/CONTOUR/LED CONTROL PLATE A total of 9 wires travel from two Molex connectors on amplifier PCB to 334344-001 Control plate. That control panel is attached by two screws on the inside of the cabinet; the woofer must be removed. The wire cluster is glued into the cabinet opening at the rear of the control panel. The hot melt glue has to be cut out and pried out, then the wire cluster should be re-glued after the control panel is serviced, for air integrity. 1) Two Black sheathed cables, each containing wire colors: Black or Blue White Red 2) Three separate wires: Red White Gray At the Control Plate: Volume pot: Black or Blue, White, Red Contour Switch: Black or Blue, White, Red Power LED: Gray, Red Contour LED: White, Black w/ 10k resistor
* Rev1 version of the PSW-D112 subwoofer is easily identified by the absence of Center channel Input and Output connectors, and is missing the"Direct Out" RCA connector.

5) Use only rosin-core or non-acid core solder; thoroughly de-flux the
surfaces after soldering.
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)
