No power to subwoofer

When I plug in the sub woofer to the wall there is no power. Do I also have to hook up the pin cord to link them.

    the subwoofer power appears to be connected(green light shows) for about 1 to seconds then disappears.

    I already posted this in another spot but here it goes: One day the light went out on the subwoofer and never came back on. We have electrical storms from time to time so I figured I blew a fuse. I took off the back plate and tested all 3 fuses and they tested fine. I then read that a bad cable from the center unit to the sub may cause the problem so I ordered a new cable and it still didn't come on. I guess I may have a blown transformer because I don't get 12v DC on the cable from the transformer back to the board (not sure if I tested it right since it has 2 reds 2 blues and a black). Any ideas?

The subwoofer is designed to be "on" at all times. It will detect signal from the cable and should start by itself. So yes, the pin cable must be connected.

How do I hook up the sub woofer to my home stereo system


You don't say what make or type either of the appliances are, so I can only answer in general terms.
First look at the back of your stereo system and see if there is a dedicated subwoofer output. If there is you should be able to find the correct lead between the two units by looking at both the connections. If the subwoofer is a powered one. IE with a mains plug on it, you have to plug it into the mains before it will work at all. The connection points also then need to be hooked up to the amp. If it's not a powered subwoofer then your main left and right channels speaker wires need to be split into using the subwoofer terminals provided. Another set of terminals on the sub, then lead to the main speakers.
Lastly if it has a dedicated subwoofer output, then the amp might have a setting that turns this on or off. So you might need to switch it on.

I wish to replace a subwoofer on a surround sound system


In most surround sound systems the sub woofer is powered separately and uses a standard RCA coax connection to the receiver/amplifier.

Replacing is simply plugging in the new and reconnecting the coax cable.

Usually the audio signal is Dolby Digital 5.1 the (.1) is the LFE Sub-woofer. The connection is between the Subwoofer RCA connector on the amplifier and connects to the (LFE-Line) in on the subwoofer speaker.

Hope this helps?

Can i put an extra sub woofer on my lg da3525 via the woofer out socket and what plug do i require to do this


Hi,

How to Connect 2 Subwoofers to One Receiver

Subwoofers produce the deep bass sounds that give home theater the realism of being at the movies. A good subwoofer can rattle the walls during action sequences, while adding depth to recorded music and a heightened sense of feeling in the midst of a televised sporting event. Because most home theater receivers are equipped with a single subwoofer jack, connecting a second subwoofer requires a simple audio adapter available at electronics stores. Self-powered subwoofers have their own built-in amplifiers to drive the bass speakers, so they cannot drain power on the main receiver in a system and thus pose no danger to the equipment, even when an extra subwoofer is connected.

Things You'll Need:

Home theater receiver
Y-adapter with RCA jacks on two ends and an RCA plug on the other, available at electronics stores.
2 RCA subwoofer cables
2 subwoofers


Instructions


Plug the Y-adapter into the home theater receiver's "Subwoofer OUT" jack.


Connect an RCA subwoofer cable to each jack on the Y adapter and route the cables to the subwoofers in the room. Because subwoofers deliver an omnidirectional sound, the boxes can be placed anywhere they won't get in the way, but within reach of an electrical outlet..


Plug an RCA cable into the "Sub IN" jack on the back of each subwoofer.


Connect the subwoofers to wall outlets and turn on each unit by pressing the power button, typically located on the back panel.


Adjust the volume and crossover settings on each subwoofer as desired. The crossover adjustment knob tells the subwppfer which low-end frequencies to reproduce from the audio signal, such as a movie on DVD. All frequencies higher than the crossover setting will be transferred to the other speakers connected to the receiver.



Tips & Warnings

Use subwoofers that are closely matched in power, as rated in watts, when using two subwoofers in a home theater setup.

Disconnect the subwoofers from the power supply while making the audio connections.


Have a nice day...

I have the sub woofer and two sp-thc5f front speakers. Can I hook this subwoofer directly to my JVC 56 high def big screen or do I need a dedicated amplifier that works this sub wooofer?


No, the powered subwoofer gets its signal AND power through the DIN connector so you'd have to second guess JVC engineers on which pins are power or signal; and what voltage level it supplies and then you'd have to come up with a source for the power. Managing the volume and relative levels would be a trick, too. Devastation lies down that path.

Get the prescribed JVC electronics or go with a whole new sound solution.

I have a jvc seteup but reciever is broke.is there a way i can get a adapter to plug sub woofer with power amp into a a yamaha reciever?the plug that goes from sub woofer also powers other speakers, cable...


Here's a manual.

http://www.retrevo.com/support/JVC-TH-M505J-Home-Theater-Systems-manual/id/318dj491/t/2/

That cable not only carries audio but it also powers the sub and other channel amplifers. Even if we could supply the pin-outs for the channels I'm not sure what we could do to provide subwoofer power. We're talking about a major rework.

This is a highly proprietary design, meaning it's really not very adaptable to normal spec audio equipment.

There's a flat-fee repair service for the receiver ($99.95, free return shipping):

Maybe they could fix your receiver.

You COULD try to reach the manufacturer for other options.

The cord /with the pin on both ends that plug in the back of sub woofer & dvd player, i need the female ,plug that on the back of sub woofer


The part is called a Din connector. You may be able to find it at www.jvcservice.com You will probably need to use the sub-woofer or the system model #, it is not listed under th-c30

FYI replacing it is not very easy.

I was given a Sharp HT-DP3000 reciever and all the speakers that go with it.. but I don't know how plug in the speakers into the wire there is a box for the two surround and a separate box for the right...


Do you have speaker wire if not you will need some, the wire is cheap about $5 bucks a roll your local department store will have it. You see a red and black tabs on the back of the unit and on the back of each speakers you push down and stick one wire in the hole. red will be your + and black will be - The two surround go on the back wall behind your seat.The center will sit on top of TV and the sattalite speakes go beside the left and right side of TV. and the sub sits on the floor in hidding behind something or under a table. (P.S, Make sure the wire is shaved about 1/4 of inch before you stick in the wire DO NOT plug the power cord in, intill you hook up all the speakers this could damage the unit. You do not need a sub woofer, if you have one great If not don't worry that will not damage the unit it has a internal switch to turn on/off the sub woofer The sub woofer offers extra deep bass that you can't get from the sattalite speakers.)

HTS 6500/37 sub woofer


the reciever should have a "subwoofer level" setting, or a "bass level control" If you cannot find this then try to place the "sub-woofer" away from walls and elevate it from the floor. This will reduce it's loudness/ intensity at annoying frequencies...

Good Luck

Sure, you can use transition between SB-WA920 system cable with other output. So, you use them as speaker. That's it.
