and thus change the audio source accordingly - all without touching anything but the receiver.
Of course, the main purpose behind the audio / video receiver circuit to drive audio to external speakers as surround sound or stereo speakers.
Most receivers have a plethora of inputs, up to 8 speakers and a subwoofer (more commonly, 5.1, or five speakers and a subwoofer), multiple video inputs, and even HDMI. You can connect your Xbox, Plasma and DVD player into the receiver and use a remote to switch between different video sources (games, TV, DVD-Video) and get your surround sound speakers pumping. Start with the inputs and outputs. If you do not understand something, read the How-To which most of them will be explained in detail.
Remember that the receiver is at the heart of the theater, whole house, so this How-To Guides really the basics of connecting a perfect home theater.
So what the hell is all this "stuff" on the back of your receiver?
I'll go near anything you find on the back of your receiver. The one I based this guide off of is a Harman Kardon AVR-247, I'll start from the top left of the unit and work my way to the right, then I start to the left of the next row and so on.
The first three inputs are for antennas. An FM antenna cable slide on the first shot, and two speaker wires would plug into the slots remaining AM. Of course, you do not need to connect your antenna, but if you want AM / FM reception through your speakers, you'll want to go ahead and do it. These are standard connections, so if you lose one of your antennas, just go buy another for a few dollars.
You've probably heard of composite video. It is a very basic video connection used by most of the components (TV, DVD, VCR, especially). Their common and inexpensive. As such, its very low quality.

Uses a composite video RCA cable (yellow) and two RCA audio cables (red and white stereo). The problem is that a composite video cable combines luminance and chrominance in the same cable, reducing the quality of the image. You waste a lot of sharpness and color begins to decrease from the original source. It is useful when you need additional input or a device that has composite video plugs. Otherwise, use something else, like component video. Similar sounds, very different.
S-Video is next to the line after composite. It uses a different type of connector (five feet in a circle) and gives you a slightly better video quality. It is also a video cable only, so you'll need to connect the audio separately. In this case, you will probably spend a couple of red and white RCA cables to the inputs of your audio.
Next up: a lot of composite audio inputs. These entries left and right channel RCA cables, usually red and white. They have the appearance of the yellow composite video cable, and even could be used
DVD-Audio discs are special DVDs that are recorded in 5.1 surround sound and can not be played by devices with support for them. These CDs go all the way up 7.1 surround sound, which means that it takes two front, two rear, two side speakers and a subwoofer to take full advantage of 7.1 surround sound. Most recipients of aid up to 7.1 today, but you will not find DVDs with that kind of capability for movies. 5.1 remains the de facto standard, not run out and buy more speakers soon.
You can skip this next little item because it is the unique character of this receiver (Harman Kardon). Bridge "has its own connection, can be developed to combine
an iPod. You must purchase a separate component that includes a docking station and special cables to connect your iPod. It is fully integrated with the receiver that displays
menus, and the tracks in front of the receiver's LCD display. This allows you to easily speakers pumping tunes, be it a stereo or full surround.
Of course, the music on your iPod is stereo sound, so the best you can get a simulated surround sound is stereo or surround sound, the same music to play on both channels before
made from the rear and center channels. Some receivers do this more intelligent than others, but more on that later.
Here is our high inputs / outputs. Basically, performance wise it has fiber optic connections (with square) and coaxial digital (like a cable RCA).
Both are 100% digital, whereas composite is analog. The only way you can get true surround sound from any source, using one of these compounds (or SACD / DVD-Audio optional)
Almost all DVD players these days have either optical or coaxial digital output (sometimes both). Many high definition cable and satellite boxes also included in these
connections, so you can enjoy 5.1 surround sound and high definition television channels. The choice between the two, is not much different in terms of sound quality, so you can use
what you want (or what you have to).
I do not think I need to place next to the image. The pair of input power. One is powered by the receiver, the other on anything you want. In this way, when you start
the receiver, gives you the power to another device (either a DVD player, CD player, cable box, whatever). I would not necessarily recommend this unless it is specifically appropriate
your needs. This is useful if you run out of business, of course.
Anything else you will never use: D-bus RC-5 input / output. It is used for infrared remote controls to take over your home theater system. Honestly, this is not something any of us will never be used. Some of the true addicts high level could be to use something for her, but I've never known a device that uses this technology. Stick to the remote that comes with the device, or buy a quality universal remote. It is not necessary for this option. Another use of this can be a bit more common: If the front panel of your receiver is locked (as in a closet), you can get an infrared transmitter to hang out in front of it. This transmitter is connected to another device somewhere in your room that accepts signals from the remote control. The receiving device then transmits the remote control on your receiver (via the transmitter has been attached to the front in the regular infrared transmitter).

Pre-outs, which is located just below the remote in / out. Pre-outs are used when you want to add a sound system to improve efficiency (and hence volume / audio quality). Average
users do not use any of this, but the subwoofer preamp output. You might want to run a subwoofer cable from the subwoofer to the subwoofer pre-out to provide
correct frequencies. This is the correct way to connect the subwoofer to your surround sound system. The other entries will not be used unless you intend to add
amplifier. This is highly unnecessary for home use. You can add an amplifier if you're trying to fill the room throughout the house with a small enough votes, but you're not, right?
Here, finally, the system of meat: the speaker connections! Harman Kardon speakers messages are used to bind, as shown in the figure. Their
they lose their job as a counter-clockwise, then sneak into the speaker wire into the covers and re-tighten by turning clockwise. Will
Give your speaker cable adjustment Nice tug probably will not loosen on itself over time. Other brands may use other types of connectors, but bind posts are very common.
You could be able to say that it is a 7.1 channel receiver because the speaker inputs.
You have space for two front left and right, two left and right rear speakers
center channel, and the two left and right "surround" channels, which is located somewhere between the front and rear speakers ("side surround" or 7.1). If you have enough
speakers, you can go ahead and connect those two extra side, but you can not play any sound on DVD 5.1. You need a DVD compatible with 7.1
surround sound, and at this stage, it is simply not a market for it. CD will explode like stereo surround through all 7 speakers, though, if for some larger space, it is a
advantage.
Our latest connectors for this receiver: component video. The best video for next to composite or s-video. You will see that all three cables (all videos)
usually red, green and blue. I do not think that's what the cable does, though - that separates the video signal into luminance and two color channels. In the past, the component
in fact represent R, G, B (division of the primary colors in the transmission and recombination of the target device), but not used in current component video
connections. Component video can carry high definition signals all the way up to 1080p, so the definition is more cost effective entry and highly available.
It is in this receiver DVI and HDMI connections fully digital video.
HDMI is the newest, fastest, clear video and audio connection available today. Its single cable can carry audio and video into one - not to mention, in high definition.
HDMI is a source of support and connect the display to use all the features. Not all DVD players, receivers or decoders support both
HDMI audio and video. And 'more and more common today to support both. The advantage is obvious: less clutter, better quality audio and video. You can get up to
HD 1080p video and 7.1 surround sound through an HDMI cable. The new cable and satellite boxes, DVD players, DVD players, high definition receivers and more expensive
full support for HDMI capability. It is best that you can get all-digital goes.
Last discussed in this article is DVI. DVI is also all digital like HDMI, but can not process audio signals. HDMI can deliver a technically superior image quality,
but I do not think anyone can make a difference. DVI supports high definition video all the way up to 1080p and HDMI. Its being used less frequently now,
but if you bought a new computer or video card in your PC recently, you probably have a DVI input (or two) port on it. Most computer monitors use DVI now and video cards
followed suit. HDMI is edging its way into the PC market, but its dominance is seen in the arena of home theater.
Now that you have taught yourself with common connections we will put it all together.
This part of the receiver as guides you through connecting surround sound 5.1 (five speakers and a subwoofer) with HDTV, HD cable or satellite, DVD, and a 5.1 receiver.
Your TV & Components
Where to put the TV depends on how big it is, the size of your room and to sit. If its 50 inches, do not sit more than 10-15 meters, but no less well.
A 60 "is the perfect game for 12-20 feet. If you have a set of 32 inches, try to sit more than 8-12 feet. Your receiver, DVD player, cable box, and other components of the course close, but not place them physically on top of each other. They all get hot, especially the receiver. If you have no choice, drag a thin piece of plywood between the components to help take the heat .
Presidents have
The first step is to define the configuration. The different rooms to call different places for the speakers and subwoofer. If the room is typically a rectangle, go ahead and place your two front left and right, somewhere flush with the TV on this side of the room. Your left speaker goes to the left corner, right speaker to the right corner. Do not bother with speaker wire yet (unless the speakers come with speaker wires connected and, in this case, we will hang for now). Note that this is the president right or left depends only on how it connects to your receiver. The speakers are not actually called "left" or "right."
Depending on how you acquired your speakers, the front speakers to be larger than your rear speakers. That's how you know they are in the front. Otherwise, your speakers are the same shape and size and you can use each for any purpose.
One exception: the center channel. Normally, a center channel is much shorter and wider than your other speakers. It should be used only for the center channel. Sometimes, all 5 of your speakers will be the same, generally at a very inexpensive setup. You can use any of these speakers for any purpose.
Your center channel should always be on top or on TV. However, you have to do is! It is called the central channel for nothing, you know. Any movie pump 90% of the voice you hear, and most of the remaining sound through the central channel. It is a vital component of your surround sound setup.
Your subwoofer should always be on the floor. If you can not place it on the floor, do it as close to the ground as possible. By placing it behind objections or in closets will diminish its effects. In an ideal setup, the subwoofer is on the floor near the TV (perhaps to the left or right) on your line of sight. Nothing should block the side of the subwoofer that air will come out of (usually covered by a grill protecting the subwoofer itself).
When it comes to finding a good place for the speakers, you can get. You can usually buy compatible speaker mounts shopping online or in can also
use of existing shelving, shop shelving, or place them on tables or other objects. No matter what you do, try to keep the speakers as close to ear level as possible. A loudspeaker mounted on the ceiling of your room will not give you the best listening experience.
The last thing to remember about the layout is the speaker wire. You will probably need at least 100 feet of speaker wire, but you often find yourself spending much more, if you
try running the cable through your ceiling, under rugs, through the basement, or around objects to conceal it. Take action and buy the yarn at least 10% more than
you think you need. Are likely to use it!
Wiring
You must know the different types of speaker cables available to you before installing your home theater. If you bought an HTIB (home theater in a box), it probably came with 100ft of speaker wire terribly expensive. You do not want! Do yourself a favor: buy some high quality speaker wire 14-guage. Whole is greater than 14-guage is just to thin and be responsive to the interests of competition, loss of quality and low quality over long distances. Fourteen gauge is a good thickness and suitable for most home theaters. Make sure it is not too thick - some son of pregnant simply will not catch the speaker on some receivers.
Some receivers use proprietary inputs from the speakers. Sony is an example. Many Sony receivers are equipped with special connectors for speaker cables, and will not accept standard speaker cable. You have to use the Sony-provided speaker cables, take the ends of speaker cables, Sony put it on your own, or buy some of these connectors from Sony directly to place in the speaker cable. My recommendation? Avoid non-recipients of the standard message of speaker wire / jacks / connectors. Search link messages or other measures that allow you to slip and end with a conventional speaker cable.
Once you have your speaker wire sorted, you have to do some cutting and stripping, if you chose to buy your own. It is much easier than it sounds, so do not worry!
Measure the length of each one at a time, cut the speaker wire, either with large scissors or a sharp knife. Now you have to strip the wire ends. Use a stripping tool or simply old scissors. You can place the scissors on the cable and gently apply a little pressure as you twist the scissors around the cable, carefully cut the plastic liner. Finally, we have sufficiently low so that only you can slide by pulling it with your fingers. You need at least 1 / 4 "of exposed wire.
Now you can connect your speakers. Note on your speaker wire the difference between the two ends. You need someone who is positive and one negative. Sometimes the coating is of a different color between the two, or there is text on one and not another. Keep track of this - no matter which side you use for positive on your speaker, use it for positive on your receiver. Crossing the two can cause damage, either immediately or in the future. It can operate in this way, but you do not want it!
Connecting the speakers is pretty easy. Front left to front left on your receiver, speaker, center to center on your receiver, etc ... Your speakers may be called "Surround" or "Surround Back" instead of just "back", but remember, if you have a receiver of 7.1 or 8.1 channel "Surround" may indicate side surround speakers not high rear speakers.
Subwoofers
Your subwoofer is going to be a bit more complicated. There are several ways to do many variations and input / output on the back of the subwoofer. I'll go with the more standard method and effective first.
You need a cable to connect your subwoofer as. If you have not or will not buy one, you can replace it with a standard red and white RCA cable (or a couple, as they usually are connected, you simply leave the cable hanging others). It will work, but really not the best way to do it. You also have whats called a Y adapter On the back of your sub, there should be an entry left / right (red and white). You plug the Y adapter for these compounds, and then the cable from your subwoofer (or RCA cable) to the other end of the Y (Note: If you do not have a Y adapter, just choose the left or right input to connect).
Now, take one end of the cable to the receiver
subwoofer pre-out. I hope you have one in power, which means it is connected. All you need to do now is plug in and your subwoofer is good.
If you do not have RCA connectors on the subwoofer, or only speaker cable (and probably not supplied), log in to age. His front left and right will plug into your subwoofer ouput jacks instead of your receiver. Then speaker wire run from the left and right inputs on the subwoofer to the left and right speaker outputs of your receiver. Thus, the subwoofer is powered by the receiver and not work as well as the. You can also take some power from the front speakers with this method. A good idea is to buy a new subwoofer to the RCA line.
Connecting the Dots
You have the hard substance of the road. Now it is finished by connecting your TV, DVD and cable / satellite. Try to always use the best opportunities first. If your DVD
has HDMI and so does the receiver, use it. If the DVD is only composite, S-Video and component, using a component video cable. When it comes to audio, you must
use digital coaxial (jacks are usually orange) or fiber (usually making is hidden in the unit and a door in it when the door is open, a red light is visible). If you are not one of them, you will not get true surround sound! When all else fails, use the composite audio connectors (red and white).
Note: Look closely at the connections on the receiver. Everything is labeled as the first set of video inputs red, green and blue component may be labeled as "Comp 1". If you use cablesfor composite audio to your sound, you need to connect the plugs that coordinate with "Comp 1". This may not be clear when looking at the receiver, so consult the manual for your receiver to determine which video inputs, including the use of audio inputs. In most cases, you will be able to configure from the receiver internal menu using the remote.
In some receivers, all the component video inputs, for example, are related to a single composite audio input (usually "DVD"), so if you connect more than one component input, which will be competing for the sound when more than one device is active. That's why you want to configure the component inputs to use different audio inputs.
The manual is the only way to understand how to proceed. Composite video is usually the height of the composite audio inputs with naming conventions like Video 1 -> 1 Video 2 Video -> Video 2, etc., but as Component and DVI cables can be. You must also configure digital audio inputs to match with the video inputs that will be used. For example, if you use the coaxial digital input (perhaps the "Digital 1"), and using the component video, you should match the "Digital 1", "Comp 1". Again, consult the user manual on how to do this.
