PB10 Subwoofer Controls and Their Function
1. Power - These lights will be red when the unit is plugged in and not receiving a signal; when the PB10 receives a signal, the lights will cycle to GREEN. If no signal is received after 10-15 minutes the lights will cycle back to RED (standby) until a signal is present again. Level Control - The subwoofer Level Control, PB10, (located on the rear panel) adjusts the volume of the subwoofer relative to the rest of the system. LFE/Normal Switch - Ordinarily placed in the Normal position - but switch to LFE when playing Dolby® Digital, DTS® or other digital surround modes - see page 9. Phase Switch - Changes the subwoofer's output to be in phase or 180 degrees out of phase with the program material. Crossover Frequency - Sets the highest frequency the subwoofer will reproduce. Line Input - Main Input connection to subwoofer (preferred). Speaker In Jacks - Main Input connection to subwoofer when line level, subwoofer, or preamp output connectors are not available, or when a high pass filter (set at 150Hz) to main loudspeakers is desired through the Speaker Output Jacks. Speaker Out Jacks - Connected to main loudspeakers when the Speaker Input Jacks are used.

Speaker Connection
When we designed the PB10 powered subwoofers, our goal was to offer the user the best possible performance combined with the most flexible and complete installation options. Please look over the following three examples to determine which description best matches your system and follow the corresponding hookup instructions. To use the binding-post speaker terminals with bare wire, unscrew the collar until the hole through the center post is visible under the collar. Insert the bare end of the wire through the hole in the post, then screw the collar back down until the connection is tight. The holes in the center of the collars are intended for banana-type connectors.
Dolby Pro Logic (Non-Digital) Speaker Level
Use this installation method for Dolby Pro Logic applications (not Dolby Digital, DTS or other digital processing), where the receiver/processor does not have a subwoofer output or a volume-controlled preamp (line-) level output: Connect your receiver or amplifier's front left and right speaker terminals to the left and right terminals on the subwoofer that are marked "High Level In." Connect the left and right terminals on the subwoofer that are marked "High Level Out" to the corresponding terminals on the back of your front left and right speakers. Connect your receiver or amplifier's center, left and right surround-speaker terminals to the corresponding terminals on the back of your center, left and right surround speakers.

Dolby Pro Logic (Non-Digital) Line Level
Use this installation method for Dolby Pro Logic applications (not Dolby Digital, DTS or other digital processing), where the receiver/processor is equipped with a subwoofer output or a volume-controlled preamp (line-) level output: Use RCA-type patch cords to connect the line-level subwoofer outputs on your receiver or amplifier to the linelevel inputs on the subwoofer. IMPORTANT: Make sure that the LFE toggle switch on the subwoofer is in the "Normal" position. Do not use the "LFE" position with Dolby Pro Logiconly processors. Note: If your receiver or amplifier only has one subwoofer output jack, then you may connect the subwoofer output on your receiver/preamplifier to either the left or right line-level input on the subwoofer. It makes no difference which jack you choose. Connect each speaker to the corresponding speaker terminals on your receiver or amplifier. Make sure your receiver or processor is configured correctly: Make sure that the subwoofer is configured as "On." Note for advanced users: If your receiver/processor has a built-in low-pass crossover filter for the subwoofer output, then the LFE switch should be set to the "LFE" position to bypass the subwoofer's internal crossover.

Dolby Digital or DTS (or Other Digital Surround Mode) Connection
Use this installation method for Dolby Digital, DTS or other digital surround processors: IMPORTANT: Make sure that the LFE toggle switch on the subwoofer is in the "LFE" position. Use the line-level input jacks for the LowFrequency Effects channel. Connect these jacks to the LFE output or subwoofer output on your receiver or amplifier. Note: If your receiver or amplifier only has one subwoofer output jack, then you may connect the subwoofer output on your receiver/preamplifier to either the left or right line-level input on the subwoofer. It makes no difference which jack you choose. Connect each speaker to the corresponding speaker terminals on your receiver or amplifier. Make sure that you have configured your surroundsound processor for "Subwoofer On" or "LFE On." The front left, front right, center and rear speakers should be set to "Small" or "Large" depending on their size and frequency response. Consult your receiver's or processor's owner's manual.

OPERATION
Power
When the unit is plugged in and the power switch is on and no signal is received, the LEDs on the front of the unit will turn red. When a signal is present, the LEDs will turn green. Note: It will take several minutes for the LEDs to turn from green to red after the input signal to the subwoofer is removed. Due to JBL's unique, high-output, high-efficiency amplifier design, power consumption is minimal when the subwoofer is not receiving a signal. Of course, the subwoofer can be turned off, whenever desired.
NOTE: Early versions of the PB10 did not have a main Power switch.
Level Control
The subwoofer Level Control adjusts the volume of the subwoofer relative to the rest of the system. Proper level adjustment depends on several variables such as room size, subwoofer placement, type of main speakers and listener position. Adjust the subwoofer level so that the volume of the bass information is pleasing to you.
Crossover Adjustments
The Crossover Frequency 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 150Hz. This control is not used when the LFE switch is in the "LFE" position.

Phase Control
The Phase Control determines whether the subwoofer's piston-like action moves in and out in phase with the main speakers or opposite the main speakers. There is no correct or incorrect setting. Proper phase adjustment depends on several variables such as 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; this switch offers the added flexibility to adjust your subwoofer for optimum performance for your specific listening conditions without having to move your speakers. If at some time in the future you happen to rearrange your
listening room and move your speakers, you should experiment with the phase switch in both positions, and leave it in the position that maximizes bass performance.
TROUBLESHOOTING
If you used the high-level (speaker) inputs and there is no sound from any of the speakers: · Check that receiver/amplifier is on and a source is playing. · Check that powered subwoofer is plugged into an active electrical outlet and is switched on.* · 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 (or no) bass output: · Make sure the connections to the left and right "Speaker Inputs" have the correct polarity (+ and ). · Make sure that the subwoofer is plugged into an active electrical outlet and switched on.* · Adjust the crossover point. · Flip the Phase Control switch to the opposite position. · If you are using a Dolby Digital/DTS receiver or processor, make sure that the subwoofer adjustments on the receiver/processor are set up correctly. · Slowly turn the Level Control clockwise until you begin to hear the desired amount of bass. Make sure that the subwoofer is plugged into an active electrical outlet and switched on.* If you used the line-level inputs and there is no sound from the subwoofer: · Check that receiver/amplifier is on and a source is playing. · Check that powered subwoofer is plugged into an active electrical outlet and is switched on.* · 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. · Slowly turn the Level Control clockwise until you begin to hear the desired amount of bass. · Make sure that you have configured your receiver/ processor so that the subwoofer/LFE output is on.

Service Bulletin
Service Bulletin JBL2001-03 Rev1 January 2002 To: All JBL Service Centers This is considered a Minor repair Models: PB10, PB12 (Revision 1 only)* Subject: Unit Will Not Switch to Standby Mode When the power cord of the PB series subwoofer is plugged into a wall outlet (and for the PB12 only, the power switch is on), and an audio signal is present, the LED's on the cabinet face will turn green, indicating the subwoofer is in the ON mode. With the audio signal removed, it will take 10 - 15 minutes for the LEDs to turn from green to red, indicating the subwoofer is now in the STANDBY mode. Power consumption is minimal in this mode. In the event you receive a PB10 or PB12 subwoofer with the complaint: "The unit will not switch to standby mode, even when the audio signal is removed" (indicated by the subwoofer's green LED's remaining on), perform the following modification: 1) Set the unit on a padded surface and remove all external cables. 2) On the amplifier faceplate, remove the (10) Phillips mounting screws around the perimeter. 3) Remove the amplifier assembly from the enclosure. If the amp is turned and supported correctly, no other connectors need to be unplugged. 4) Locate Zener Diode D10 and Resistor R42 (22k). See illustration. These parts must be "swapped", i.e., R42 soldered into the D10 location, and D10 soldered into the R42 location. VERY IMPORTANT: Observe polarity on D10 in new location. 5) Replace amplifier; test subwoofer to assure the unit goes into the standby mode 10 - 15 minutes after removing the Audio input signal.

Service Bulletin
Service Bulletin JBL2001-04 Rev2 February 2003 To: All JBL Service Centers This is considered a Minor repair
Models: PB10, PB12 (Revision 1 only)* Subject: Hum, Buzz or "Thumping"
In the event you receive a PB10 or PB12 subwoofer complaint: "There is an audible hum or buzz", or the subwoofer "thumps" or "pops" every 10 seconds, then review the conditions below to determine the most effective solution: A) Audible Hum with unit on, Green LED is ON, hum disappears completely when the connecting input cables (RCA or Speaker-Level) are disconnected: Very long runs of line-level input cables, particularly in parallel with AC power cords, may induce hum in the audio cables. Check audio cables for defects, broken ground connections, or replace low quality cables. Try plugging the AC power cord from the subwoofer into a different AC service outlet other than the outlet the rest of the audio equipment is plugged into. B) Mild Audible Hum under all circumstances when power cord is plugged in outlet. Hum level does not change whether the LED's are Red or Green, or input cables are connected or disconnected. Level control adjustments do not change the hum level. This may be a mechanical hum caused by the power transformer. Note that a slight hum, within design limits, may be noticeable in a very quiet room, when you are close to the unit. This is acceptable within the PB10/12's product and price category to most customers, but not to others. If the mechanical hum is unacceptable to the customer, then replace Power Transformer. PB10: JBL part# 80135. PB12: JBL part# 80116 C) Loud Hum, under all circumstances. It may be louder when LED's are Green vs. Red ; it may be affected by the position of the Level control. The subwoofer may "thump" or "pop" approximately every 10 seconds. Reset the digital subwoofer amplifier by unplugging the AC power cord. Wait 30 seconds, then plug the cord back in. Repeat this 2-3 times if necessary. For #B only - If the unit still does not function correctly, then check and replace main Power Supply capacitors C1 and C2. Both Value and df should be checked, with a GenRad model 1657 Digibridge or equivalent Value should be the rating listed below, within this tolerance: +80/-20 % A df value of higher than 15% (.15) should be considered defective.

For #C only - If the unit still does not function correctly, then replace Power Amp Module S53/64AMI as per instructions below: PB10: JBL part# 60301 PB12: JBL part# 60302 1) Set the unit on a padded surface and remove all external cables. 2) On the amplifier faceplate, remove the (10) Phillips mounting screws around the perimeter. 3) Remove the amplifier assembly from the enclosure. If the amp is supported correctly, no other connectors need to be unplugged. 4) Locate the Power Amp Module S53/64AMI, see location on the following page. It is the large black or gray component with a metal case. On the solder side of the circuit board are 28 soldered connections. NOTE: See special handling instructions for S53/64AMI on the following page. 5) Replace the amplifier assembly back into the cabinet; replace the screws. 6) Test the unit and confirm the original problem has been corrected. NOTE: THE PB10/12 REVISION 1 AMPLIFIER MUST ALWAYS BE TESTED WITH A WOOFER OR 4 OHM RESISTIVE LOAD.

S53AMI/S64AMI - Power Amp Module SAFETY PART
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. Align white indent marker on Amp Module with indent marker on main PCB; alternately observe position of label on top of the Module; incorrectly replacing the Module 180° in the PCB slot will result in its destruction. 2. All AC powered test instruments (meters, oscilloscopes, etc.) must have a floating ground, i.e., be connected to an isolation transformer. 3. Align and position the Amp Module before soldering.
