I am not able to hear the dialog while playing DVDs. The background is great and comes through all 5 speakers, however, to be able to listen to the dialog, I have to switch over to 2-channel or Stereo. ...

Well let me first ask is the center chanel working? or properly hooked up. Cause most of the times when in 5.1 the talking or "dialog" as you put it comes only through the center channel its just kinda how they do it. Listen to see if the center channel is working. if you are unsure try hooking up a speaker that you know works into the center channel speaker output. If no sound comes out then the reciever possible has blown its center channel. Please follow up with a comment and i will be glad to assist you further thanks, Midwes-tek

How to set up a seven-speaker home theater system

Set up a home theater

How to connect your speakers

In order to deliver surround sound, home theater systems require 5, 6, or even 7 speakers--and that's not even counting the subwoofer. Connecting all those speakers together can be quite a challenge, so here's a quick overview of the basics.

If you don't have an all-in-one, home-theater-in-a-box system, you'll probably need to supply your own speaker cables. There are several different types available--they vary in terms of wire size (or gauges) and termination types. Make sure you pick cable that's a good match for your speakers and receiver. And make sure they're long enough; the rear-channel cables in particular will be stretching all the way around the room.

Once you've selected your system and have all your speakers ready to set up, begin by placing each speaker at or near its intended location. Then, attach the cables to them one by one. After securely fastening one end of the cable to the speaker, connect the other end to the appropriate speaker output on the back of the A/V receiver. Be sure to connect the cable to the correctly labeled output.

For instance, the front-right speaker wire needs to go to the terminal labeled front-right. Also, make sure that each speaker connection is in phase, meaning negative to negative and positive to positive. Otherwise, your system's sound will sound out of whack. Repeat the process for every speaker in your system. Note that the subwoofer uses a coaxial-style RCA cable instead of standard speaker wire.

Once all the wires are connected, you should test the system with several DVDs and CDs, to ensure that everything is in working order.

For our first example, we used an elaborate 7.1-channel system, so it may have 1, 2, or several more speakers than your system. Some systems even employ wireless rear speakers, or virtual surround-surround modes that simulate multichannel experience from 3, 2, or even 1 speaker. And some listeners still prefer good old stereo sound from 2 speakers. No matter what type of speaker setup you prefer, however, the wiring basics remain the same.

How to position surround-sound speakers and a subwoofer
To get the best performance from a surround-sound speaker system, you must install each speaker in the correct location. There are three basic types of surround-sound speaker systems.

  • The 5.1-channel system has five satellite speakers and a subwoofer.

  • 6.1-channel systems have six satellites and a subwoofer.

  • And 7.1-channel systems have seven satellites and a subwoofer.

Start by placing the center speaker either directly above or directly below your TV. The center speaker can be perched atop a direct-view TV or mounted on the wall. Aim the center speaker at ear level.

In most cases, the front-left and front-right speakers can be wall mounted or placed on stands. However, if your speakers have rear-panel bass ports, they should not be wall mounted. Space your front-left and front-right speakers the same distance apart as the distance between your center speaker and your listening position. Position the front-left and front-right speakers no more than two feet above or below the front-center speaker. The tweeters in the front-left and front-right speakers should be roughly at ear level relative to your seating position.

Ideally, the surround-left and surround-right speakers should be mounted on the side walls of your room, slightly behind or parallel to your listening position. If your speakers have rear-panel bass ports, place them on stands instead. If installing the speakers on the side walls isn't practical, you can mount them on the room's rear wall or place them on stands behind your listening position. The surround speakers can be installed up to two feet above the front speakers.

Also, 6.1 surround systems have a back-center speaker. You'll typically mount this on the rear wall of your room, centered behind your seating position. Position the back-center speaker no more than six feet behind the surround-left and surround-right speakers. If your speaker has a rear-panel bass port or if the rear wall is too far behind your seating position, place the back center speaker on a stand instead. The back-center speaker should be installed at the same height as the surround-left and surround-right speakers.

Instead of a single back speaker, 7.1 surround systems use a back-left and a back-right speaker. These, too, are typically mounted on the rear wall of your room. Position the back-left and back-right speakers so that each is approximately aligned with the left and right edges of your listening position. Place the back-left and back-right speakers no more than six feet behind the surround-left and surround-right speakers. If your speakers have rear-panel bass ports,or if the rear wall is too far behind your seating position, place the speakers on stands instead. Install the back-left and back-right speakers at the same height as the surround-left and surround-right speakers.

A subwoofer is the last component of a 5, 6, or 7.1 system. Because bass frequencies are nondirectional, you can place the subwoofer in various locations. You may get the best performance by installing the subwoofer in the front of the room, approximately six inches from the wall. If you want more bass, try placing the sub near a corner in the front of the room.

Connect your DVD player to your A/V receiver--digitally
To hear a movie's soundtrack in surround sound, you must first connect your DVD player to an A/V surround-sound receiver. You'll need to make what is called a multi-channel-compatible connection.

The easiest way to do this is to use a cable that carries a digital signal. There are two digital options: optical and coaxial.

An optical digital connection, also called TosLink, uses pulses of light to deliver a digital signal. According to some experts, one advantage of optical digital connections is that optical cables don't pick up noise, while lower-quality coaxial cables can. Many, but not all, DVD players have an optical output. Most A/V receivers have at least one and usually multiple optical inputs. Plug one end of the optical cable into the DVDs player's optical-out jack. Plug the other end into the receiver's optical input.

Finally, you need to tell your receiver to use the optical connection whenever you switch to the DVD input. This is called assigning the input. Information about this simple process can be found in your A/V receiver's manual.

A second option is a coaxial digital connection. This type of connection is also used for cable TV, but the connectors are different. This type of coaxial cable has an RCA connector. Coaxial cables are less expensive than optical ones. In fact, you can use any old RCA cable to make a coaxial digital connection, and you won't lose any audio quality.

Most, but not all, DVD players, have a coaxial output. Some have coaxial and optical outputs, so you get a choice. Audiophiles argue over which connection is better, but it's very hard to hear the difference. Most A/V receivers have at least one and usually multiple coaxial inputs. Plug one end of the coaxial cable into the DVD player's coaxial-out jack. Plug the other end into the receiver's coaxial input.

Finally, tell your receiver to use the coaxial connection whenever you switch to the DVD input. Again, your A/V receiver's manual will have instructions for assigning an input.

The Best Place to Put Your Surround Sound Speakers

If you can’t feel the vibrations everywhere—in your cheeks, ears, toes—you’re not getting the most from your surround sound system. One easy way to improve surround sound quality is to focus on speaker placement. has a detailed tutorial, offering such tips as:
  • Place your center channel speaker directly above your TV—centered if possible. Align the front edge with the front edge of your TV screen to reduce distortion caused by sound reflecting and diffracting off the TV’s cabinet.
  • Position your front left and right speakers in front, and at equidistant points to the left and right, of your primary listening spot. Your front speakers should be at a 22°–30° angle with respect to your television.
  • The tweeters should be at ear level when you’re seated.
  • Position surround sound speakers so that they’re ear-level when you’re standing.

Front left speaker problem

The best way to confirm is to switch the speakers from the left to the right with the same cable . If your speakers sound good, then we have to check the cable. However if your speaker is sounding dull then there is no doubt that your speaker is faulty. So check this interchange. Also reduction of treble is when you cable length goes beyond a limit and also is related to bad cable quality. Tryto reduce the length and you have a solution . Hope this helps. Good day

The rear and centre speakers are not working but the front and subwoofer speakers are working. What do I need to do to get the three working. In the booklet it says the rear speakers might not work becasue...

From them manual Troubleshooting section:

"When listening to a CD or radio, sound is output to the front
speakers (L/R) only. Select "PRO LOGIC II" by pressing
PL II (Dolby Pro Logic II) on the remote control to use all
six speakers.
• Make sure that the DVD disc is 5.1-CH compatible.
• If you set C, SL, and SR to NONE in the speaker mode in the
audio setup of the setup screen, no sound is heard from the
center speaker and the rear left and right speakers. Set C,
SL, and SR to SMALL."

This means you might want to check your speaker settings again and make sure the Cenyer and Surrounds are defined.

Rear spekers no sound

Is the source signal of a surround sound type? Also, be sure that the rear speakers are on, (if your receiver has a speaker switch on it), and they are hooked up properly.

I bought the LG LHT854 and i dont know how to connectthe speakers because i dont know which ones are the front speakers and rear speakers, all 4 speakers are the same and i dont know how wich is wich..

All four of the small speakers are identical, the original speaker wires are color coded. the very ends are all black and red, corresponding to the black and red connections on the back of the receiver and on the speaker, and there is another color band lower on the wire, which corresponds to the color on the receiver speaker connectors that details front right, front left, rear right, rear left, center, subwoofer.

If you are using standard speaker wire, it has two colors. Pick one for the red, and one for the black.
Just be consistent and connect all speakers the same at both ends (Copper color to plus-red / silver color to minus-black)

Can not get 3 speakers on my samsung home theater to work!

There are a few settings that will just give you a stereo output. The first one is with the Pro Logic II. If you press the PLII Mode button on the remote it will go through a series of settings from MUSIC ➞ CINEMA ➞ PRO LOGIC ➞ MATRIX ➞STEREO ➞ MUSIC. Pro Logic setting will only produce sound from the front speakers and Stereo from the front speakers and the sub. Put it on Matrix for 5.1 surround sound.
Also for speaker settings follow the instructions below.
Signal outputs and frequency responses from the speakers will automatically be adjusted according to your speaker configuration and whether certain speakers are used or not.
In Stop mode, press the MENU button.
Press the Cursor down button to move to Audio and then press the ENTER button.
In the SPEAKER SETUP, press the ENTER button again.
Press the Cursor button to move to the desired speaker and then press the ENTER button.
For C, SL, and SR, each time the button is pressed, the mode switches alternately as follows : SMALL ➞ NONE.
For L and R, the mode is set to SMALL.
SMALL : Select this when using the speakers.
NONE : Select this when no speaker is connected.
Press the RETURN button to return to the previous level.
Press the EXIT button to exit the setup screen.
It also seems that with this system, if you are on 5.1 surround but your music source is only in stereo, you will only hear stereo.
