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


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


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...

YAMAHA AV receiver RX-V861 I have the message 'Vol-fix' appearing on Zone 2 and no sound. This was working fine until then

Setting the RX-V861 remote control to operate Zone 2:
  1. Using a ballpoint pen or similar object and press the [CODE SET] button RX-V861 remote control. The[TRANSMIT INDICATOR]on the remote should flash twice.
  2. Using the [NUMERICAL KEY PAD] on the remote and key in 9992, the [TRANSMIT INDICATOR] should flash.
Assigning the receivers internal amp for Zone 2:
  1. Set the remote control selector to [AMP]. (Located to the right of the volume buttons on the Remote.).
  2. Press the [SET MENU]button on the remote control.
  3. Arrow down to Manual Setup and press the Enter button on the remote control.
  4. Arrow to the [SOUND MENU] option and press the [ENTER] button on the remote control.
  5. Arrow to Speaker Set and press the [ENTER] button on the remote control.
  6. Arrow to the EXTRA SP ASSIGN and select ZONE2
  7. Press the [RETURN] button on the remote control to exit out and return to the Manual Setup.
NOTES: There is an option for setting the Maximum Volume and Initial Volume in the Zone Set menu.
  • Max Volume: This is an optional feature but isrecommended to prevent the accidental change in volume levels thatcould damage the speakers and receiver.
  • Initial Volume: This is also a great feature that would seamlessly start the volume level for the second or third zone at the desired level.
We do not recommend using any Speaker Selector boxes to enable more than the recommended number of speakers per terminal.
Controlling Zone 2 using the RX-V861 remote control:
  1. If the Main Zone on the receiver is on, press the [POWER BUTTON]down and while holding that button down press the [PHONO]/[**] button on the remote. The [TRANSMIT INDICATOR] will light up.
  2. You will not be able to use the following buttons on the remote: (Pressing any other button will cause the remote to exit Zone 2 mode. [POWER], [STANDBY], [VOLUME], [MUTE] and the [INPUT SELECTOR] buttons [DVD], [CD], etc.)

There are the instructions as written straight from yamaha. If you need any further assistance please let me know.
Thank you,

Speaker left channel? must be broken as both speakers are still working on right input (channel, not sure if this is the terminology?)

Have you tried isolating the problem to see what exactly the problem is? First I suggest disconnecting the left speaker from the system and test the speaker by it's self. If you have any technical knowledge and an ohm meter, you can connect an ohm meter to the two wires comming from the speaker and see if you get 8 ohms or less. You SHOULD see something in the neighborhood of 8 ohms of resistance if the speaker is good. If you're not a techy and want a simpler "go/no-go" test on the speaker, then take the two wires going into the back of the speaker and BRIEFLY touch them to the two terminals of a 9 volt battery. If the speaker is good, you will hear a "pop" in the speaker as the battery connects. Again, ONLY BRIEFLY touch them. DO NOT connect them to the battery and allow them to stay on for more than about a half second or so, else you run the risk of burning up the voice coil in your woofers.
If the left speaker passes the test, then let's look at the receiver unit. I am not familiar with this particular make and model, but I dare say it should have multiple inputs. Just to be extra certain that the speaker wasn't somehow the problem, go ahead and connect the right speaker to the left channel and let's test the left channel of the receiver. Try using the various inputs on the receiver (i.e. am/fm, CD in, AUX in, Video in, what ever it may have).. Does the left channel yield ANY sound at all under any conditions?
If I'm not mistaken, the system has a separate power amp and receiver unit. Try putting a signal into the aux inputs of the power amp it's self using an RCA cable. You can connect the other end of the RCA cable to most any other CD player, or you can usually touch your finger to the center conductor on the RCA cable and listen for a buzz or click in the left speaker output. If it doesn't give any sound, then the problem is most likely in your amplifier. If it does give you sound, then we need to look at the receiver.
Something else I just noticed about this particular unit you have, is that it uses a ribbon cable to connect the receiver to the amplifier unit. I would suggest that if the amplifier checks good, then try replacing this ribbon cable with another one. You may have to have one specially made, or you may be able to order one. I hope that helps.

Rear speakers not working

Your FM tuner will only generate sound from the front sepakers. CD's, Tape, and I guess mp3 player, as well, will only play through the front speakers.
I've included a link for the manual. The audio on this rig is pretty complex. read through the info, especially pages 11,12,13, and play with the audio controls.

Then hooked it up through directv receiver and sounded better. then switched from direct to comcast and hooked the bose up throught the comcast hd receiver and the volume is aweful. same deal, have to crank it up high. Since the stereo built into the tv sounds so much better I disconnected the bose and am going to sell it.

No reception or sound on rear speakers.

Here's the fix: power off the sub-woofer and wait for 60 secs before powering it on again. My rear receiver works every time now.  I guess the sub-woofer isn't just a dumb speaker; it has some kind of smarts in it too.
Prior to this, I had only tried cycling power to the DVD player itself.  I also re-seated the two, fat cables connected to the junction box. One of them had worked itself slightly loose and the result was completely absent speaker channels.

Surround sound

It must be about the sound quality need of your amplifier. The sound processor simply needs to get clear signals from sources such as fm/am receiver, dvd/cd players etc. in order to manage'em to give you the optimum surround sound. If the fm receiver has an "FM MUTE" option, I recommend that you turn it on. By doing so, you'll receive only good quality fm stations, furthermore your amplifier will let you get surround sound. The second issue you mentioned has its own answer inside. Use a "new" cd player, you can get optical cables, digital coax cables to improve the performance if you like..
