Cauti

3、on 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 t

4、he 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 Curren

5、t. 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 0.5mA,

6、 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

22、L Service CentersThis considered a Minor repair Model: ARC SUB10 / DS-10 Subject: Check Solder Joints in Event of Failure Some performance related complaints in the ARC SUB10 / DS-10 powered subwoofer may be caused by cold Solder connections between the 28 pins of the Power Amp Module and the main c

23、ircuit board. When troubleshooting, failure to check these joints can result in erroneous conclusions or wasted time. In the event you receive a ARC SUB10 / DS-10 Subwoofer with the complaints “Dead, or No Output, or Motorboating (Oscillation)”, perform the steps listed below first before any furthe

24、r 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 re

25、moving 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 Solder connections to the Module. 5)Regardless of whether you can visibly see breaks in any of the connections or not, carefully re-Solder all

26、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

27、. 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. 14 Amplifier/SubwooferARC SUB10/DS-10 SERVICE BULLETIN JBL2000-01 - JANUARY 2000 To all JBL Service CentersWarranty labor rate: MINOR repair Model: A

28、RC SUB10 / DS-10 Subject: Failure of C6 In the event you receive a JBL subwoofer corresponding to one of the above models with the complaint “no output” and capacitor C6 (10uf 50v NPE) is damaged in the amplifier, replace with the following part: JBL part# 30712 (10uf 100v NPE) General reference for

Prob

31、able Cause: The High level Input terminals, potentiometers, RCA jack, and switch(es) are behind a sealed cover to protect the air-tight integrity of the cabinet enclosure. Solution: 1)Unplug all external cables from the subwoofer; place the cabinet on a padded surface. 2)Remove any subwoofer grille;

32、 remove the woofer from the cabinet. Detach the two connections from the woofer terminals. 3)Remove all Phillips screws holding the amplifier to the cabinet; remove the amplifier. 4)Remove all knobs, nuts, and Philips screws from the outer control section of the amplifier faceplate. 5)Locate the sea

33、led cover on the inside of the amplifier faceplate (see illustration); the bead of adherent must be broken to remove the main PCB with front panel components from the plastic faceplate. This is most easily accomplished by CAREFULLY using a box cutter, exacto knife, or similar sharp instrument. First

34、 scrape all excess material from the three surfaces; then force the blade into the groove between the rear cover and the faceplate. DO NOT attempt to remove the rear cover from the main PCB. 6)When enough material is removed, the main PCB with cover can be pulled away from the faceplate, exposing th

35、e components. 7)After servicing, a bead of “silicon seal” or similar adherent must be applied to all surfaces where it was removed. Reassemble the rest of the components in reverse order. 16 Amplifier/SubwooferARC SUB10/DS-10 17 Amplifier/SubwooferARC SUB10/DS-10 CABINET EXPLODED VIEWS ARC SUB10 CAB
