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!

Critical Components

All components identified with the IEC symbol in the parts list and the schematic diagram designate components in which safety can be of special significance when replacing a component identified with . Use only the replacement parts designated in the parts list or parts with the same rating of resistance, wattage or voltage.

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-D110/DPS-10 CONTROLS AND THEIR FUNCTION

PSW-D110/DPS-10

1. Power

- (PSW-D110 ONLY) This light will be RED when the unit is plugged in and not receiving a signal; when the PSW-D110 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. Level Control

- The subwoofer Level Control,

(PSW-D110, located on the front panel, DPS-10, on the rear panel) adjusts the volume of the subwoofer relative to the rest of the system.

3. High Pass Control

- Controls the the roll-off point of the highest frequency the subwoofer will produce.

4. Phase Switch

- Changes the subwoofer's output to be in phase or 180 degrees out of phase with the program material.

5. Low Pass Control

- Controls the roll-off point of the lowest frequency produced at the High Pass Output

Jacks.

6. High Pass 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.

7. Line Input

- Main Input connection to subwoofer

(preferred).

8. Speaker In Jacks

- Main Input connection to subwoofer when line level, subwoofer, or pre-amp output connectors are not availible, or when a high pass filter

(set at 180Hz) to main loudspeakers is desired through the Speaker Output Jacks.

9. Speaker Out Jacks

- Connected to main loudspeakers when the Speaker Input Jacks are used.

Crossover Adjustments

High-Pass Control

• This control is only active if you are using the hook-up method described in detail on page 8, Figure 3. The

High-Pass control determines the frequency at which the main speakers 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.

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.

3) 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 3.

This method of hookup can offer the highest level of performance for your complete loudspeaker system. The

PSW-D110/DPS-10 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

TROUBLESHOOTING

If you used the high-level (speaker) inputs and there is no sound from any of the speakers, check the following:

• Receiver/amplifier is on and a source is playing.

• Powered subwoofer is plugged in.

• Check all wires and connections between receiver/amplifier and speakers. Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured.

• Review proper operation of your receiver/amplifier. If there is low bass output, check the following:

• Make sure the connections to the left and right “Speaker

Inputs” have the correct polarity (+ and –).

• Make sure that the sub-woofer is plugged into an active electrical outlet.


• Adjust the crossover point.

If you used the line-level inputs and there is no sound from the subwoofer, check the following:

• Receiver/amplifier is on and a source is playing.


• Check all wires and connections between receiver/ amplifier and subwoofer. Make sure all wires are connected.

Make sure none of the wires are frayed, cut or punctured.

• Review proper operation of your receiver/amplifier.

SERVICE BULLETIN JBL9902 REV1 - MAY 1999

To all JBL Service Centers

Model: PSW-D110

Subject: Grille removal

When servicing the PSW-D110 subwoofer, care must be taken when removing the metal subwoofer speaker grille.

Removing the grille by grasping one grille edge and pulling it off with a hinge-like action could result in broken grille pins.

To Remove

1)

Place the subwoofer on a padded surface, with the grille facing upwards.

2)

Grasp the grille with both hands in two of the opposite cut-outs between the grille and the cabinet.

3)

Pull up on the grille gently, rocking the grille frame back and forth, evenly on both sides, until the grille is free of the cabinet.

Note:

For grille replacement, there are two versions of the grille.

Earlier version has a .220" (5.6mm) grille pin diameter. JBL Part# 200510

Later version has a .410" (10.4mm) grille pin diameter. JBL Part# 200511

In the case of a missing grille, where pin diameter cannot be measured: take approximate diameter from the rubber grille cups in the subwoofer cabinet.

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.
