JLB PSW-D110 Subwoofer Issues

HI,
C6 on my PSW-D110 blew up. I replaced it with a 100V, now I get some low frequency hum for about 10 seconds and then the fuse blows. Can you suggest any other parts which I should check besides the C6. Thanks, Pat.

    I don't understand the solution. Grounding may be an issue but would this cause the fuse to blow?

When you replaced the capacitor did you replace it properly oriented. if it is the round can type there is a positive and negative. you should make sure the replacement was also the exact value capacitor that you blew. sounds like it has blown again or there are other capacitors that are in need of replacement. a bad capacitor will give you humming.

I don't recall the exact output section for those units, but I would suspect that either there is a shorted output transistor or the speaker itself is blown. Try disconnecting the actual speaker and see if the amp stays on. If so, let me know. I will try to look up the schematic on this in the meantime.

    Hey Pat,



    There was a service bulletin that requires the following parts to be replaced should C6 get smoked. Replace the listed parts and get back to me if you have further problems.



    Dan



    Parts:



    C6 - 10ufd 100V

    C24 - 100nFd 50V

    R23 - 20K 1/2W

    R46 - 47ohm 1/4W

  • ABRsvcs Sep 09, 2008

    Please note that the actual power module is no longer available. Lets hope that is not the problem...

C6 must be 50V, are you sure 100 V will work?
Do you have full schematics?

    I can see on a forum there is an issue on C6, this had been published on a JBL bulletin.

    C6 must be replaced.

    Try also replacing the C24 cap with a 100nF, 50V cap, the R46 resistor with a
    47ohm, 1/4 Watt resistor, and the R23 resistor with a 20kilo-ohm, 1/2
    Watt resistor.

    The whole set can be ordered from JBL on a kit, Kit part number is 30721.

Humming is always caused by low earth resistance so check the earthing.

What is the size of the JBL PSW-D110 fuse?


The fuse is a 250volt 1.25 amp slow blo.
First thing I would do is check C6 to see if it is bulge or blown - regardless replace it with a 10ufd 100volt Non-polarity capacitor. If the fuse blows again unplug the blue wires from the transformer and plug in unit to an outlet. If fuse does not blow then problem is on PC board. I have a service manual for this item. Probable causes on PC board are Filter Caps, Bridge rectifier (DBA), Amplifier module, or fragments of C6 even causing shorts on board if it had blown.

I have bought C6 from MCM Electronics for under .50 cents but you have to put shrink tube on one lead and bend it back along the body and solder both leads in the board.

Good luck

I think the subwoofer power light should be green when the bass is working and it stays red with very low bass output. Not sure if I blew speaker or if connections are off, seems to be subwoofer itself. ...


If it makes any sound at all the speaker is probably not blown, the connections are probably on and the fuse is ok.

You don't say to what it is attached and if the setup for bass/lfe managament settings produce the same or a different result than program material does.

You also don't say how the sub is driven (speaker level or Line Level) and if it's a full-range or low-frequency-only input. All these things matter, as does your source electronics and its settings for bass management.

Try setting the low-pass higher and the high-pass lower.

The manuals would be a good place to start. Go to retrevo.com.

Can we use the subwoofer as an amplifier for speakers? it has jacks for speaker in/out, but i can't figure out how to make it work because the speakers have no sound.


I don't believe this hookup is amplified; but, if you have used the regular unfiltered speaker connections from your receiver/amplifier to hookup the subwoofer, the system will pass the signal thru the outputs subject to the crossover adjustment on the back panel. You cannot get the full signal if your system is sending only the bass signal to the subwoofer. I have copied the instructions below from the manual. You would set the high freq crossover to the low end of your satellite's frequency range. The full manual is here: http://www.jbl.com/EN-US/Products/Pages/ProductSupportDetails.aspx?PID=PSW-D110

High-Pass Control
• If you hooked up your subwoofer
as shown in Hookup
3 on page 4, you also have
the capability of adjusting
the high-pass frequency.
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.
• If you hooked up your subwoofer
as shown in Hookup
1 on page 3, the high-pass
frequency is fixed at 180Hz.
• If you hooked up your subwoofer
as shown in Hookup
2 on page 4, there is no
high-pass control. Unless
your receiver/amplifier
incorporates a high-pass
crossover, your main speakers
will continue to get a
full-range signal.
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 low- and high-pass
controls to the same frequency
and adjust from that point.

Subwoofer will not product sound. (ignore product)


Please verify that we're talking about a JBL PSW-D110 here. I'm making no assumptions.

Are you running the Ipod into its L & R RCA jacks as prescribed?

Have you tried it with something besides the Ipod? A sub isn't supposed to reproduce a full range signal. Come to think of it, is the Ipod even outputting anything within the sub's operational range? I don't expect a lot of real bass comes out of one.

Perhaps you could try adjusting the Low Pass up to 180 to see if anything anywhere near the 'real' bass region is present.

Bottom line: There's not a lot of need for a sub (and no other speakers) running off of any music sound source. You wouldn't hear anything above 180hz.

C6 Polarity?


Hi CALSunbelt

There is no polarity to be conscious of when you are using a BiPolar cap. They can be used in either direction.

If I remember these correctly, there is a bad coupling cap in the amp section. You should see it as the top should have ballooned up. Replace the cap and you should be OK.
