Service Bulletin
Service Bulletin JBL2003-06 - April 2003 This is considered a Minor repair
To: All JBL Service Centers
Model: S120PII
Subject: Distortion When Coming Out Of Standby
In the event you receive an S120PII subwoofer with the complaint "There is a brief chirping sound, or
short oscillation that occurs when the unit is in the AUTO mode, in Standby, when it's triggered ON
with a music signal", follow the procedure below to correct this condition:
Synopsis: Replace D60 (RLS4148 diode) with a 3.6V Zener Diode; add new Resistor.
1) Remove the amplifier assembly from the subwoofer cabinet (12 Phillips screws).
2) Remove the Plastic Amp Cover from the faceplate (4 Phillips screws).
3) The area of concern is on the Class D Driver PCB (Small Upright PCB on the MAIN AMP PCB). A
long, thin, soldering iron tip is recommended. Care must be taken not to damage surrounding
components, like large inductor pair L8.
4) Locate, remove D60 (RLS4148 diode); replace with a 3.6V zener diode, JBL Part# ZMM5227BCT-ND.
When replacing D60 the polarity of the new (zener) diode should be reversed.
5) Add new 27K resistor, JBL Part# 299-27K, to the indicated connections. (This component,
electrically, will be in parallel with R37, reducing its value to <22K). Assure the leads do not come
into contact with any other connections; insulate the leads if necessary.
6) Replace amp cover and return amplifer assembly to cabinet.
7) Test the subwoofer to assure the distortion is no longer present.

S120PII Test Set Up and Procedure
SYSTEM AURAL SWEEP TEST
Equipment needed:
· Function/signal generator/sweep generator
· Integrated Amplifier
· Multimeter
· Speaker cables
· RCA phono cables (pair)
General Unit Function (UUT = Unit Under Test)
Switches/knobs on the amplifier faceplate:
Crossover Frequency Adjust full CW (150Hz)
Phase switch either position
Normal/LFE switch Normal
Auto On/Off - either position
1. From the signal generator, Connect both right and left line level inputs (RCA jacks) to signal generator and
UUT. Use Y-cable if necessary from mono source.
2. On the amplifier, turn the LEVEL control full Counterclockwise (Min).
3. Turn on generator, adjust to 100mV, 50 Hz.
4. Plug in UUT; turn the power switch ON. Turn LEVEL control full Clockwise (Max).
5. LED's (top of UUT) should now be Green; immediate bass response should be heard and felt from port tube
opening.
6. Turn LEVEL control full Counterclockwise (Min). Turn power switch OFF.
7. Connect one pair of speaker cables to one set (either R or L) of the Speaker Input terminals on UUT. Cables
should be connected to an integrated amplifier fed by the signal generator.
8. Turn on signal generator and adjust so that speaker level output at the amplifier is 2.5V, 50 Hz.
9. Turn power switch ON; turn LEVEL control full Clockwise (Max).
10. Bass response should be heard and felt from port tube opening.
Sweep Function
1. Follow steps 1-5 above, using a sweep generator as a signal source.
2. Sweep generator from 20Hz to 1kHz. Listen to the cabinet and drivers for any rattles, clicks, buzzes or
any other noises. If any unusual noises are heard, remove woofer and test.
Driver Function (Woofer)
1. Remove woofer from cabinet; detach + and - wire clips.
2. Check DC resistance of woofer; it should be 4.4 ohms±10%.
3. Connect a pair of speaker cables to driver terminals. Cables should be connected to an integrated
amplifier fed by a signal generator. Turn on generator and adjust so that speaker level output is 5.0V.
4. Sweep generator from 20Hz to 1kHz. Listen to driver for any rubbing, buzzing, or other unusual noises.
