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.

Sound in only one speaker


With a music CD playing, and the volume on the SA-404 set to a lower (but audible) level, try the following steps while closely listening for music from the speaker that is not functioning (some crackling or screeching sounds may be heard when removing and reconnecting the cables).

Remove & reconnect the traditional RCA type audio cables that originate from the CD player at the connection point at the rear of the SA-404 several times. If the cables can be removed from the CD player, do it to that end too if no music is heard. If the audio cable is a single coaxial dolby digital type carefully do the same thing to it - at both ends if needed, too. The optical cables usually don't fail the way you describe so if they're being used it may be a problem with the CD player.

You might also try moving the RCA type cables to a different input (try TAPE or another available input) if the previous steps don't solve the problem. If the problem is present on the new input (TAPE or another available input), the issue lies with the cables or the CD player. Try connecting with NEW cables to the CD input. If still failing - try TAPE input again. If still not working, I would feel comfortable saying the CD player has some sort of problem.

Digital Optical port to 8-pin din


Optical digital cables can't be magically wired to copper inputs. NO digital signal can be magically connected to an analog interface and work.

Even if you could do what you propose, how would you control volume?

Why don't you just connect the BluRay to the JVC system and let IT handle the audio to the sub and satellites?

Run an optical cable to the JVC TH-C60's Optical In port. Make sure there are no tight bends in the optical cable as that will degrade its ability to transmit a signal.

Subwoofer with speaker wire?


Back in the old days, subwoofers were powered by the voltage from your receiver, through speaker wire.
Nowadays, subwoofers have their own power, hence not having speaker wire connections anymore.
It's unlikely that you'll be able to connect your old subwoofer to your new receiver.
You'd need to get a new one, which if you don't mind buying closeout, can be found on eBay pretty cheap.

I CAN NOT GET ALL 5 SPEAKERS TO WORK


I know this is not the answer that you want to hear, but: That television is not capable of delivering audio output to all 5 speakers - it is a stereo-only TV, which only delivers 2 channels.

Furthermore, that Coby DVD-937 only has Digital Audio outputs rather than inputs, which is very strange and complicates our problem immensely. You will get 5-channels with DVD or radio play, but getting 5 channels for TV is not possible without additional equipment.

The manual for the Coby mentions a "Digital Decoder Amplifier," which would work. You would connect a digital audio cable from the area marked "Coaxial" on the back of the Coby to a digital audio IN on the back of an external amplifier. You would connect the speakers to this amplifier, instead of directly to the back of the Coby. Then you would need a cable or satellite box with digital audio outs (fairly common nowadays) to another digital audio IN on the back of the amplifier. The cable or sat box you may have already, but you may need to purchase such a "Digital Decoder Amplifier" or other digital amplifier with appropriate speaker wires and 2 digital audio input slots (not to mention two digital audio cables). Fairly complex. Possibly expensive.

No 5.1 surround when adding a Philips upconvert player to the San


Sounds like you are getting analog signals from your componet cables and a true digital input from your HDMI into your tv.

However that unit is Analog audio input x 1 only.
So i dont think your going to get true digital surround sound.
The problem being

Hook up


well u cannot hook almost any devices with the SC-HT500.
I have this homecinema system for 5 years now, and i had to buy another stand alone DivX player to hook it up, but can't get the sound in dolby from the standalone player since the panasonic SC-HT500 has only 2 analog stereo RCA ports (audio in) in the back and a scart (A/V out) and component video (Video out).
At that time it was a very good system, but since i have bought a Full HD LCD tv with 1080p capabilities, I realised that my home cinema system i.e the Panasonic SC-HT500 is kind of useless, in the sense that you cannot even change the player for another one since the whole spaker and power connections are made trhough a special cable from the subwoofer. :(
best solution is that put the system back in a corner and get a new system which is not an all-in-one system. Preferrable get home cinema systems that come with a receiver, separate dvd player and speakers and subwoofer hooked to the receiver.
you asked how to hook these devices to your tv,, well the panasonic dvd recorder is better if you connect it via HDMI cable if you can. In the other case, connecting them with a scart cable would be another solution.
