1. Speaker Level Outputs - Connect the Left, Center and Right speakers to these connectors. 2. Speaker Level Inputs - These High Level Inputs are for receivers that do not have line-level "pre-amp out" or "subwoofer out" jacks. When a pair of main or satellite speakers are attached to the OUTPUT terminals, they are driven the full range of frequencies as generated by the music source (receiver, amplifier, etc.) 3. Line Level Input - These left and right Line Level Inputs are normally used when the receiver/ processor has line-level "pre-amp out " or "subwoofer out" jacks. 4. Auto/On Switch - This switch allows you to set the Mode of the Amplifier. Turn the switch to Auto to cause it to Auto-matically turn on when it receives a signal and Auto-matically turn off after twenty minutes without a signal. If this switch is left "On", the subwoofer will always be ON when the power switch is turned On, regardless of input signal.

5. Subwoofer Level - This knob controls the volume level of the SUB125. 6. LED - Red & Green. The LEDs indicate the Mode status that the subwoofer is in. When the SUB125 is turned OFF neither LED will be lit. The Green LED will light when the SUB125 is ON and receiving a signal. The Red LED will light when the amplifier has not received a signal for twenty minutes. The subwoofer will turn on when your receiver/amplifier begins playing again. 7. Power Switch - This the master power switch. Use it (in Off mode) to disconnect power to the amplifier. 8. Fuse - Use only same type of fuses. For the U.S. 120V version use only a 2A 250V fuse. For the European 230V version use only a 1A fuse. 9. AC Cord

General Function
UUT = Unit Under Test 1. Connect both right and left line level inputs (RCA) to signal generator and UUT. Use Y-cable if necessary from mono source. VOLUME control should be full counterclockwise. 2. 3. 4. 5. 6. 7. 8. Turn on generator, adjust to 200mV, 50 Hz. Plug in UUT; red LED should be ON. Turn VOLUME control full clockwise. LED should turn Green; immediate bass response should be heard and felt from port tube opening. Turn off generator, turn VOLUME control fully counterclockwise, disconnect RCA cables. Connect one pair of speaker cables to both high level input terminals on UUT. Cables should be connected to an integrated amplifier fed by the signal generator. Turn on generator and adjust so that speaker level output is 3.0V, 50 Hz. Turn VOLUME control full clockwise. Green LED should light, immediate bass response should be heard and felt from the port tube opening.

Sweep Function
1. 2. Follow steps 1-4 above, using a sweep generator as a signal source. Sweep generator from 20Hz to 300Hz. Listen to the cabinet and drivers for any rattles, clicks, buzzes or any other noises. If any unusual noises are heard, remove driver and test.

Driver Function
1. 2. 3. Remove driver from cabinet; detach + and - wire clips. Check DC resistance of driver; it should be 3.3 ohms.

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.

SIMPLE TROUBLESHOOTING
If 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 and is either in the "On" or "Auto" position. · 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 no sound coming from one speaker, check the following: · Check the "Balance" control on 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 ­). · Powered subwoofer is plugged in and is either in the "On" or "Auto" position.

If there is no sound from the surround speakers, check the following:
· 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 and its surround sound features. · Receiver mode must be in Dolby Pro logic, Dolby Digital, or any other mode that creates a surround-sound effect. Even under normal operation, when viewing movies and television, surround sound is not present at all times at a high volume - only when the program has chosen to send information there.

If the system plays at low volumes but shuts off as volume is increased, check the following:
· Check all wires and con-nections between receiver/ amplifier and speakers. Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured. · If more than one pair of main speakers is being used, check the minimum impedance requirements of your receiver/amplifier.

Service Bulletin JBL9901
To: All JBL Service Centers - January 1999 This is considered a Minor repair Model: Sub125 (SCS125 Powered Subwoofer) Subject: Amplifier plate overheating; Blown fuses
In the event you receive a Sub125 (SCS125 Powered Subwoofer) with the complaint "amplifier plate is getting too hot", or "the unit is blowing fuses", perform the necessary steps listed below to change the bias current of the amplifier. This procedure should be performed on all Sub125 amplifiers being serviced for any reason: 1. Set the subwoofer cabinet on a padded surface with amplifier facing upwards. 2. Remove the (14) Philips screws holding the amplifier and inner plastic cover to the cabinet. Four of these 14 screws are in each corner, slightly larger and just inside the smaller corner screws. 3. Remove amplifier assembly carefully . Do not pull the amplifier out of the cabinet too much; it can disconnect the speaker wires. (The amp assembly can be laid on one corner of the cabinet for the remainder of the procedure without disconnecting the speaker wires). 4. Carefully pry plastic cover off amplifier assembly. If you are too aggressive Molex connector P104 may be damaged; speaker wire inside the cover has little extra length. Lift the left side of the cover first to avoid disconnecting the cable at P104; this connector is located on the right side of the plate inside the cover. 5. Once the cover is pulled back, locate VR101. See Figure 1. 6. Using a thin Phillips screwdriver 5 or more inches long, set trim pot VR101 to Full CCW position (Minimum level). Be gentle to avoid damage to the part. 7. If necessary, replace blown line fuse with h/k part# FS1067, (2A Slo-Blo 5 x 20mm GMC type). 8. Replace the amplifier in the cabinet; replace all (14) screws to secure the amplifier plate and plastic cover.* 9. Functional Test - Set the LEVEL control to minimum (Full CCW). Connect an AC Wattmeter to the AC input line and turn the unit ON; maximum AC measured power should not be more than 12.5 watts. 10. Connect music signal from a CD source and increase volume to a medium level to verify sound from the subwoofer. Do not increase volume to a point where the unit is driven into clipping. No evidence of distortion and/or rattle inside the box should occur. 11. Conduct warm-up for 10 minutes; turn LEVEL control Full CCW or remove signal. Input power as measured by AC Power meter should not exceed 13 watts. If value exceeds this, re-check pot. VR101 position if necessary. 12. Add an adhesive label (dot) to the amplifier plate with the letter "a" written on it; if the customer's outer carton is available, add an "a" with a marker to the "SCS125" printing on the carton in all places where it appears.
Unmodified Sub125 (SCS125 Subwoofer) Factory Modified Sub125a (SCS125 Subwoofer) Orange Label on amplifier plate: This area is designed to become quite warm during normal operation Outer carton marked SCS125 Outer carton marked SCS125a

* Alternately, the amplifier may be driven out of the cabinet by attaching a 4 ohm 25 watt load resistor to the output terminals, and using a 50 Hz sine wave input signal adjusted to achieve 7 volts at the load resistor for the warm-up test.
