Just answered that question for you in another post, but here it is again in case you miss it.

Hi there, Is the socket actually broken, or is it just playing up. It may just need some dry solder joints reflowed to fix it. If you are lucky, this may be done without a full strip down.

If you need to replace it, you will have to pull the board out of the unit, or at least the back panel completely off to get access to the soldering of the socket to replace it. This is not a difficult job, but often requires almost complete disassembly of the amp to do so. Time consuming...yes. It is something that unless you have some confidence at dismantling and reassembly gear, I would suggest that you refer it to a repair man. Good luck, I am happy to answer any more questions you may have.

regards
Graeme

Adding a LFE input to wireless samsung subwoofer


I doubt there is a way to put an RCA jack into that sub. All the input comes from the wireless board. If you tried to put an RCA jack in there, the impedance and signal levels will not match what they need to be. Also, those soundbar system subs don't put out a lot of bass, I doubt it would even improve the sound of your current system if you could get it to work.

How do I use my Bose Subwoofer with a different receiver??


Hi,
You can use Bose Sub woofer with any receiver. There is a set of "Audio Input" jacks on the back of the Bose. Connect the plugs on the one end of the audio cables to the "Audio Input" jacks on the back of the Bose.
Connect the plugs on the other end of the audio cable to an "Audio Out" jack on the receiver.
If the "Audio Out" jacks do not match with the plugs of the audio cable, then you need to use adapter or modify the audio cable.
In case "Audio Out" jacks are not provided on the receiver, you may take the audio output from headphone socket.
hope this will help you.

Thanks...!!

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.

Need to hook up to keenwood powered subwolfer 1050sw and im a girl and dont know how


The receiver has a subwoofer out jack on the back. The powered sub has a LF input jack on the back. Connect the two with an audio cable that has 'RCA' plugs on both ends.

Receiver cannot recognize subwoofer


As I implied earlier, take a clue from the physical style of connectors for both parts of the subwoofer function in the old and new receivers:

RCA connections are for Line Level signal between components only.

The input (bare wire) at the speaker is for AMPLIFIED signal.

You can't just modify one to fit the other and expect magic to happen. Be glad you didn't do it the other way around and modify an amplified (speaker level) outout into a Line Level input. You likely would have smoked that component.

Your subwoofer is a passive speaker, that is, like any other speaker it needs an amplifier. Many subs are self-powered (amp built-in) and they would mate well with the RCA sub output of the receiver.

Get yourself an Active (self-amplified) Subwoofer and run UN-MODIFIED RCA cables to it, according to its instructions, from the Sub Out of the receiver. Or get an amplifier between your receiver and the sub you have.

What kind of wire do I need to connect the subwoofer to the av-d58? The subwoofer is the same that came with the receiver but I have somehow misplaced the connection wire.


Without knowing more about the subwoofer (powered, passive, what kind(s) of input it takes, I have to take a wild guess. Most powered subwoofers use the old standard RCA cable. I there are two jacks on the sub for Left and Right input you just get an adapter to make the cable plug into two jacks.

Connect powered subwoofer


  • If your receiver has a dedicated subwoofer line level output, we recommend connecting your subwoofer to this jack. Most receivers will have just one (mono) subwoofer output, while quite a few subs require two inputs. You can use an RCA "Y" adapter cord , which is a cable with one female RCA jack at one end, and two male RCA plugs at the other. Some receivers require menu settings (such as "sub-on" or "front speakers-small") that must be made before the sub output will be active.

    Woofer problem


    If I am not mistaking here, you need a self powered subwoofer to use with this unit. Those are line driven outputs for this unit. Make sure there is a wall plug on the sub that is plugged in. Good Luck
