Welll if your handy with solder then you can just get the rca solderables from radioshack ans some speaker wire solder pos to pos and neg to neg and voila you got some patch cable just make sure that the outside neg- part of the rca matches the neg  lead you want-z

Subvoofer burns fuses and dosen`t work


If there is a subwoofer with an end-amplifier inside there could be a capacitor problem by deformed or leaking capacitors but also look at the heatsink where are often mosfets placed or vintage conventional NPN / PNP transistors and they are in most times short -circuited between GDS gate drain source if its a mosfet or between base collector emitter if there is a transistor is used maybe when an active transistor output stage is used is it also handy to make a little test bank , to make a serial connection from mains over a 200 watt lamp. this in order to save fuses.

25877625-kscs3earlhitqtfzpvr402k1-3-0.png Beware ! The accu is example for mains 120V and the meter for the subwooferamp powercable (not for the speakercable) its only an example for a connexion diagram how to spare the fuses in a test mode. if there is a fuse placed

Can I use a JX-S900 Y/C separated I/O to run two subwoofers out of same reciever??


Yes, on two conditions:

1) the JX-S900 needs to be a proper matrix switcher. It has to have the ability to route 1 input to more than one output.

2) the sub signals need to be low level RCA/phono, and not high level speaker wire connections. That's not just about the type of connector. It's about the signal going through those wires. A low level RCA/phono sub connection conducts a maximum 0.7 Volt. A speaker wire connection can transmit 30 Volts! If you put 30 Volts in to a line level switching device such as the JX0S900 you'll fry it.

Provided that the above two criteriia are both met, then yes it will work.

  • Connect the AV receiver's sub out to Source 1 - white RCA phono.

  • Connect the two subs mono LFE Left input (white RCA) or the single black RCA/phono inputs to the JVC's outputs 1 and 2 - white RCA/phono.

  • Set the source routing: input 1 goes to output 1 and 2

What wire do I plug in for the subwoofer cause I I have read cables but there's 2 and I only have 1 connection for the sub on the back of the stereo


This subwoofer is probably powered directly from the amplifier and doesn't have an internal amp. The connections are probably the same type as for any other speakers. And, there are probably additional connections for the rest of the speakers. The connection on your amp is likely an RCA phono plug connector that sends low level signals to a powered subwoofer. To connect a passive subwoofer, one without a built-in amp, the main speaker outputs connect to the subwoofer and are then sent to the regular speakers connected to additional terminals on the subwoofer. You may need an owner's manual for the subwoofer to determine how it should be connected.

Im trying to hook up a paradigm pdr-12 to my tv and xbox 360 and need an idea of how to do this the right way so it only plays the bass and nothing else


Hello there this subwoofer has a built in crossover variable from 50hz to 150hz which means that any signal you feed it the sub it will ignore anything but bass anyway.

As for the connection it is made quite difficult if you don't already have an amplifier powering your other speakers, usually home cinema amplifiers have a low level pre out for subwoofers, for which you would just need a phono to phono cable.

However if it doesn't and you have any type of amplifier with at least 2 separate left and right speakers you can connect the wires from these into the subwoofer and it will output the bass from these 2 channels.

Another option is to use a mono to stereo (2 to 1) phono cable where the 2 connectors at one end connect to a tape or record output on your amplifier and the single phono at the other connects to the subwoofer, the same would go if you have a red & white phono (RCA) output on your TV you could also use this to power the sub, in the worst case scenario you could use a single to single phono or rca cable to connect one of the output channels (left or right) on your TV to the subwoofer however this would mean that the subwoofer would only output bass from either the left or right channel.


Hope this helps


Kind Regards

Unable to receive optimum output. The bass is totally flat !


Hi, ok the Bose Acoustimass III system consists of two small cube speakers and one subwoofer unit called the Acoustimass bass module. If the subwoofer stops working, three points can be the cause of the failure. The Bose Acoustimass III is a passive system, meaning the speakers do not power themselves, but instead are connected to a receiver or amplifier. Thus, the amplifier, the speaker between the amplifier and the subwoofer, or the subwoofer itself could be the issue.

Things You'll Need:

* Amplifier
* Speaker cable
* Extra subwoofer


Instructions


Disconnect the speaker cable from the back of the Bose Accoustimass bass module and connect it to a subwoofer that is known to be working. If the subwoofer works, the bass module needs to be replaced.


Disconnect the speaker cable from the back of the receiver or amplifier you are using and from the back of the subwoofer in Step 1.


Connect a speaker cable that is known to be working between the back of the receiver or amplifier and the back of the Accoustimass module. If the module starts working, then the cable was the issue.


Disconnect the speaker cable from Step 3 from the back of the amplifier or receiver, then connect the cable to the subwoofer port on the back of an amplifier or receiver that is known to be working. If the subwoofer works, the receiver was the issue. If the subwoofer still does not work, verify that the speaker cable is in the subwoofer port of the receiver/amplifier and that the cable is connected securely to the subwoofer.



If you think you did the connection properly,Fine... If not you can use the manual from the below link and know how to connect it properly..

I do not know how to connect the woofer KEF PSW3500 to the amplifier Denon 4310. BCC sold me a 1 on 1 plug, but the woofer needed to plugs (left and right).


Bass is mono directional in the main,and while your sub has a left and right input ( because a few amps do have left and right sub outs) only one of them is required (usually marked as MONO on the sub). You can also get a Y splitter phono adapter and connect the single cable you have to both sockets, which is how I have mine set up. This is most common

When I hook up the speakers in the back to the left and right side for the in and out, do I connect the front or rear speakers. do the speakers connect to the subwoofer first then to my receiver or the...


I was trying to find an owner's manual or picture of the rear panel of the sub, but had no luck. The subwoofer is a powered type - or "active" speaker. This means it has a built in amplifier. These active subs usually provide for one or both "low level" and "high level" inputs. Low level signals are usually carried by shielded coaxial cables and have RCA type plugs on the end. The low level is also called "line level". This is an un-amplified signal that might be heard on cheap earphones - but that's about it. It is similar to the output of a tape deck, DVD or phonograph. These signals require an amplifier to be heard. If you have a sub woofer output on your receiver or amplifier, you could run a patch cable between the low level input on the subwoofer and the subwoofer output of the amp or receiver. You receiver or amp may call this output "low frequency effects" or similar. The front and rear speakers would then connect directly to the receiver or amp's corresponding connections.

If you lack low level outputs on the amp or subwoofer, you'll need to run speaker wires from the amplifier or receiver's front left and right speaker output terminals to the subwoofer's high level input terminals. High level signals are speaker connections or amplified signals. These are typically connections that accept bare wire connections. The front speakers would then connect to the subwoofer's front left and right speaker output terminals. The rear speakers connect to the amplifier.

I hope this helps - and good luck!

Help----i have aw825 wireless speaker and a yamaha rx-v730--how do i connect the two?


You need to connect a stereo out from the amplifier to the transmitter for the speaker. I believe the speaker unit comes with the required adapters which will probably be rca/phono's to stereo mini-jack.
