SOURCE: No sound coming from my Infinity BU2 subwoofer.

I suspect that whatever semiconductor does all the amplifaction has departed this life. If you check the PC board it might point to a burnt out part or a blown one. If not look at anything big or with a heatsink on it.

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.

How do I hook it up to my Surround sound reciever?


Hooking up a subwoofer is dependent upon what hookups are availble on the receiver and subwoofer. Does your receiver have a specific subwoofer output? If so, is it set of speaker-wire terminals, or is it an RCA jack? The Wharfedale can accomodate either one of these as an input. There are four speaker posts on the back of the subwoofer, and there is a single RCA jack input.

No sound coming from my Infinity BU2 subwoofer. Powers up, light comes on, relay clicks, and nothing.

I WANT TO SELL 4 MIRAGE AVS 200 AND ONE avS 100 SPEAKER. WHAT IS THE VALUE IF THEY ARE IN EXCELLENT CONDITION?


There is a set of 4 avs 200's on Ebay for ~$200 OBO so figure around there. Really though these are 10 year old bookshelf speakers so the market for them is pretty soft especially now that Polk and the other big names have affordable bookshelf speakers... (I'm just giving my set to a friend when I move this month)

Subwoofer FPS 1000 4.1 sound bad


hello,

I had a problem closely with my FPS 1000 4.1 sound works four point surrond : my subwoofer sounds a metallic noise when the bass are loud.
Maybe it is the same problem ? :

It were vibrations that go through the subwoofer and cause the noise.

Check the four screw well (the four hole on the back of the subwoofer). Put your finger on them to clog them and hear if your problem is solved.
If yes, put scotch on them.

Secondly (i think you have disassemble your subwoofer), you can put silicon joincture on the box near the circuit, under the translucides cables. (the box where there are the plugs). >> if there are any hole between his box and the speaker, there will be some metallic noise (vibrations trough the box and the back plugs).



bye

Replacement speakers


You should be able to use any of the "bookshelf" speakers to replace the Front Left/Right and Rear Left/Right. I would go ahead and get a dedicated Center speaker. I bought a Pioneer center speaker and a pair of KLH 3-way bookshelf speakers at Radio Shack at low prices. I also bought a pair of Insignia 3-way bookshelf speakers. I put this all together with a Durabrand Home Theature system (dumping the satellite speakers). There is better range and a much fuller tone with these speakers versus the originals. Even if you hadn't lost the speakers, I would recommend this as a good upgrade.
Hope that helped.
