What’s a Receiver?
A receiver is that big, heavy factor that you simply plug your audio system and other elements into (like a DVD participant, TV, CD player, Xbox, PlayStation, iPod, and etc.). Its the “brain” of the present, really. The idea of connecting all your components to a receiver is the concept of audio/video switching, allowing you to change to different video sources (like TV, DVD, camcorder) in your TV
and thus altering the audio supply accordingly – all with out touching anything however the receiver.
In fact, the primary goal behind audio/video switching with a receiver is to drive audio to external audio system, like encompass sound or stereo speakers.
Most receivers have a plethora of inputs; as much as eight audio system and a subwoofer (extra generally, 5.1, or five audio system and a subwoofer), a number of video inputs, and even HDMI inputs. You possibly can plug your Xbox, Plasma, and DVD participant into the receiver and use one distant to modify between all of the completely different video sources (video games, TV, DVD video) and have your audio system pump out surround-sound. Let’s start with inputs and outputs. In the event you do not perceive something, read through the whole How-To as most of will probably be defined in detail.
Needless to say a receiver is the hub of your complete residence theatre, so this How-To will really information you through the fundamentals of connecting your complete residence theater.
So what the heck is all this ‘stuff’ on the again of your receiver?
I will go over absolutely anything that you would discover on the again of your receiver. The one I am basing this guide off of is a Harman Kardon AVR-247 I’ll start from the top left of the unit and work my option to the best, then I’ll begin at the left of the next row and so on.
The first three inputs are for antennas. An FM antenna cable would slide on to the first jack while two speaker wires would plug into the remaining slots for AM. Of course, you do not have to plug your antennas in, however if you would like AM/FM reception by means of your speakers, you will wish to go ahead and do that. These are commonplace connections, so should you lose one in all your antennas, simply go purchase another for a few bucks.
You have most likely heard of composite video. Its a really primary video connection used by most any element (TV, DVD, VCR particularly). Its common and its cheap. As such, its very low quality.
Composite uses an RCA cable for video (yellow) and two extra RCA cables for audio (pink and white, stereo). The issue is that a composite video cable combines luminance and chrominance in the same cable, reducing the standard of the picture. You lose plenty of sharpness, and the color begins to degrade from the unique source. Its useful when you need the extra input or the gadget you’re connecting only has composite video. Otherwise, use one thing else, like part video. Sounds related; very different.
S-Video is next in line after composite. It makes use of a distinct sort of connector (5 pins in a circle) and provides you marginally higher video quality. It’s also a video-solely cable, so you will must plug in audio separately. On this case, you will most likely use a pair of purple and white RCA cables on your audio inputs.
Next up: a ton of composite audio inputs. These inputs use left channel and proper channel RCA cables, typically red and white. They appear similar to the yellow composite video cable, and you possibly can even use them for video and the yellow for audio, however let’s keep the colour scheme how it is 
Composite audio is the underside-of-the-barrel in audio. Its perfectly wonderful for most use, however should you’re on the lookout for high quality surround sound, you don’t want composite. Sport systems, just like the Wii or Xbox, and really basic DVD players are an ideal match for composite audio.
The same goes to VCRs, CD players, and anything that solely has a composite audio output. Plus, if you don’t have surround sound, or your receiver is simply two channels (2.1, stereo sound), you won’t have the ability to use something but composite audio. Note that there is a composite audio enter underneath every composite video input in order that it is simple to match them up. Plug them within the incorrect inputs and you will not get sound while you’re on that exact video input.
Here we’ve got one of the least-used options of a modern receiver: 6 (or 
channel direct input. That is only used for 2 functions: SACD or DVD Audio. SACD is an acronym for Super Audio CD. It is a proprietary audio format developed by Sony for particular CDs which might be recorded in 5.1 surround sound. Meaning you need a CD or DVD/CD player that supports SACDs, a receiver with SACD support (as in the image), and of course Super Audio CD’s. DVD Audio is the same thought, totally different brand, totally different media (its a DVD, not a CD!).
DVD Audio discs are special DVDs that are recorded in 5.1 encompass sound and can solely be played by devices with assist for them. These CDs go all the way as much as 7.1 encompass sound, that means you would want to have two entrance, two rear, two aspect speakers and a subwoofer to get pleasure from full 7.1 encompass sound. Most receivers help up to 7.1 now but you won’t discover DVDs with that form of functionality for movies. 5.1 surround is still the defacto commonplace, so do not run out and buy extra speakers any time soon.
You could skip this subsequent little merchandise as a result of it is distinctive to this brand of receiver (Harman Kardon). The Bridge” is a proprietary connection they developed so that you can connect
an iPod. You might want to buy a separate part that features a docking station and particular cables to attach the iPod. It fully integrates with the receiver, displaying
menus and songs on the front LCD display screen of the receiver. This allows you to easily pump your tunes through your audio system, whether or not or not it’s stereo sound or full encompass sound.
After all, the music in your iPod is stereo sound, so the very best you will get is simulated surround sound or stereo surround; the identical music enjoying in the entrance two channels
is put by means of the rear and middle channels. Some receivers do this more intelligently than others, but extra on that later.
Here we’ve our excessive-finish sound inputs/outputs. Mainly the same efficiency sensible, you’ve got fiber optic connections (with the square shape) and digital coaxial (similar to an RCA cable).
Each of those are a hundred% digital, whereas composite is analog. The one way you can get true surround sound from any source is by using one of these connections (or the SACD/DVD Audio choice)
Almost all DVD gamers lately have either optical or digital coaxial outputs (generally, both). Many excessive definition cable and satellite tv for pc containers additionally include these
connections so you’ll be able to take pleasure in 5.1 surround sound on high definition channels. Choosing between the two, there’s really no completely different in audio quality, so be at liberty to use
what you would like (or what you’re pressured to).
I don’t suppose I want an image for the subsequent plug. Its a pair of power inputs. One is for powering the receiver, the opposite for no matter you’d like. This way, if you flip
on the receiver, you give power to the opposite machine (be it a DVD participant, CD participant, cable box, no matter). I do not essentially advocate this except it particularly suits
your needs. It is helpful when you’re working low on retailers, of course.
One thing else you’ll never use: D-bus RC-5 input/output. This is used for infrared distant controls to take over your own home theater system. Truthfully, its not something any of us will ever use. A number of the real excessive-finish junkies may be utilizing one thing for it, but I’ve never even come across a device that uses this technology. Follow the remote that got here together with your unit, or purchase a high quality common remote control. There is not any need for this option. An alternate use for this may be a bit more common: if your receiver’s front panel is blocked (like inside a cabinet), you might get an infrared transmitter to latch on to the entrance of it. This transmitter would hook as much as another machine somewhere in your room that can settle for alerts from your remote control. The receiving device then transmits the distant’s instructions to your receiver (via the transmitter you’ve got connected to the front over the regular infrared transmitter).
Pre-outs , located right below the Remote in/out. Pre-outs are used if you’d like so as to add an amplifier to your system to boost the power (and hence quantity/audio high quality). Common
users is not going to use this for anything but the subwoofer preout. You will want to run a subwoofer cable from your subwoofer to the subwoofer pre-out to offer it with
the appropriate frequencies. That is the proper technique to join your subwoofer to your encompass sound system. The other inputs will not be used until you plan on including
an amplifier. That is extremely unnecessary for house use. You would possibly add an amp for those who’re trying to fill a room the size of a small home with enough sound, but you’re not, proper?
Right here we lastly get to the meat of the system: the speaker inputs! Harman Kardon receivers use bind posts for connecting audio system, as seen in the picture. They
work by being loosened up as your flip them counter-clockwise, then you sneak the speaker wire in underneath the caps and tighten them back up by turning clockwise. This’ll
give your speaker wire a nice tug fit that most likely won’t loosen up on itself over time. Other manufacturers could use other types of connectors, but bind posts are very common.
You might have been able to inform this is a 7.1 channel receiver because of the speaker inputs.
You’ve acquired room for two entrance left and right audio system, 2 rear left and proper speakers,
a middle channel, and two left and proper “surround” channels that are positioned someplace in between your front and rear speakers (“facet encompass”, or 7.1). You probably have sufficient
audio system, you can go ahead and plug in these extra 2 side ones, however they won’t play any sound in any respect on a 5.1 DVD. You would need a DVD that supports 7.1
encompass sound, and presently, there just is not a marketplace for it. CDs will gladly blast stereo encompass by all 7 audio system, though, so for some larger rooms, that’s an
advantage.
Our ultimate set of connectors for this receiver: component video . The very best video you may get subsequent to composite or s-video. You may discover its a set of three cables (all for video),
often Red, Inexperienced and Blue. Do not suppose that’s what the cable does, although – it separates the video signal by luminance and two separate coloration channels.

In the past, element
did it in reality signify R, G, B (splitting the primary colors in transmit and recombining them at the vacation spot device), however that is not used in present part video
connections. Part video can carry excessive definition indicators, all the best way as much as 1080p, so it’s the most cost efficient and readily available high definition input.
Not seen on this receiver are DVI and HDMI, the two all-digital video connections.
HDMI is the latest, fastest, sharpest video and audio connection obtainable today. Its the only cable that can carry audio and video in a single – not to point out, in excessive definition.
HDMI should be supported by the source and the display you are connecting it to to use all of its features. Not all DVD players, cable packing containers, or receivers support each
audio and video in HDMI. Its changing into an increasing number of of a standard now to support both. The benefit is evident: less cable clutter, increased high quality audio and video. You’ll be able to get up
to 1080p excessive definition video and 7.1 surround sound by way of an HDMI cable. Newer cable and satellite tv for pc containers, DVD players, excessive definition DVD players, and costlier receivers
support the full capability of HDMI. Its the perfect you may get as all-digital goes.
The last connection for this text is DVI. DVI can also be all digital like HDMI, nevertheless it can’t course of audio signals. HDMI might present a technically superior image,
however I don’t assume anybody may tell the difference. DVI helps excessive definition video all the way in which up to 1080p, similar to HDMI. Its being used much less continuously now,
however if you’ve bought a new computer or video card for your PC just lately, it probably has a DVI (or two) port on it. Most laptop displays use DVI now and video cards
have adopted suit. HDMI is edging its means into the PC market, but its dominance is seen within the dwelling theater arena.
Now that you’ve got familiarized your self with frequent connections, let’s plug all of it together.
This a part of the receiver How-To is going to information you through hooking a 5.1 surround sound system(5 speakers and a subwoofer) with a excessive-definition TV, a high-definition cable or satellite tv for pc field, a DVD participant, and a 5.1 receiver.
Your TV & Parts
The place you place your TV relies on how massive it’s, how giant your room is, and where you’ll be sitting. If its 50 inches, do not sit greater than 10-15 ft away; but no less, either.
A 60″ set is ideal for 12-20 feet. If you have a 32 inch set, attempt to sit no farther than 8-12 feet away. Your receiver, DVD participant, cable field, and different components ought to obviously be close collectively, but don’t place them physically on top of each other. They all get scorching, particularly your receiver. If in case you have no different alternative, slide a skinny piece of plywood between the elements to help dispense the heat.
Lay Out of Audio system
The first step is to lay out your setup. Totally different rooms name for different places in your speakers and subwoofer. In case your room is a typical rectangle, go forward and place your two entrance left and right speakers someplace flush with the tv on that side of the room. Your left speaker goes toward the left nook, proper speaker towards the precise corner. Do not hassle with speaker wire but (unless your speakers include speaker wire connected already; in that case, simply let them dangle for now). Be aware that which speaker is left or right is solely dependent on how you connect them to your receiver. Your speakers aren’t really designated “left” or “right”.
Relying on the way you acquired your audio system, your front speakers could be larger than your rear speakers. That’s how you recognize they’re for the front. Otherwise, all your speakers are the same shape and measurement, and you should use each for any purpose.
One exception: the center channel. Often, a center channel is far shorter and wider than your other speakers. It ought to solely be used for the middle channel. Typically, all 5 of your speakers might be the same, usually on a really cheap setup. You need to use any of those speakers for any purpose.
Your middle channel should all the time go both immediately on top or beneath your television set. However you need to do that, get it performed! It is not called the middle channel for nothing, you know. Any movie will pump out nearly ninety% of the voices you hear and a majority of the rest of the sounds via the middle channel. It’s a vitally essential component to your surround sound setup.
Your subwoofer should all the time be on the floor. Whether it is not possible to place it on the ground, get it as near the ground as possible. Inserting it behind objections or in closets will diminish its effects. In an ideal setup, the subwoofer could be on the ground close to the TV (perhaps off to the left or right) in your line of sight. Nothing should block the facet of the subwoofer that air will come out of (usually coated by a grill defending the subwoofer speaker itself).
On the subject of discovering a great spot to your speakers, you would possibly want to mount them. You possibly can usually buy compatible speaker mounts on-line or in stores. You may as well
use present shelving, buy some shelving, or place them on tables or different objects. No matter the way you do it, attempt to keep the audio system as close to ear degree as possible. A speaker mounted at the ceiling of your room is not going to give you the optimal aural experience.
The last thing to keep in mind about format is speaker wire. You will in all probability want at the very least 100ft of speaker wire, however you will usually find yourself using rather more if you happen to
strive working wire through your ceiling, below carpeting, up by the basement, or round objects to conceal it. Take measurements and purchase at least 10% extra wire than
you assume you need. You’ll most likely use it!
Cabling
It’s good to know the totally different type of speaker wire out there to you earlier than setting up your house theatre. When you bought an HTIB (residence theater in a box), it most likely came with 100ft of horribly low cost speaker wire. You don’t need that! Do your self a favor: purchase some high-high quality, 14-gauge speaker wire. Something increased than 14-gauge is just to thin and will be inclined to interence, high quality loss, and poor quality over longer distances. Fourteen gauge is a good thickness and appropriate for most dwelling theatres. Be certain that its additionally not too thick – some speaker wire simply is not going to slot in to the speaker wire jacks on some receivers.
Some receivers use proprietary speaker inputs. Sony is one example. Many Sony receivers have special connectors for speaker wire and won’t settle for a normal speaker wire. You may need to make use of both the Sony-supplied speaker wire, take the ends off of Sony speaker wire and put it by yourself, or buy a few of these special connectors from Sony straight to put on your speaker wire. My advice? Keep away from any receivers with non-commonplace speaker wire posts/jacks/connectors. Search for bind posts or other jacks that can help you slide in and clamp down on a typical speaker wire.
Once you have obtained your speaker wire sorted out, you will must do some reducing and stripping in case you opted to buy your own. That is means easier than it sounds, so don’t fret!
Measure out each size one at a time, chopping the speaker wire with either actually nice scissors or a sharp blade. Now it’s essential strip the ends of the wire. Use either a stripping instrument or plain old scissors. You may place the scissors on the cable and gently apply some strain as you twist the scissors around the cable, carefully slicing into the plastic coating. Finally, it’ll get weak sufficient that you could just slide it off by tugging on it together with your fingers. You want at the very least 1/four” of uncovered wire.
Now you can join your speakers. Note in your speaker wire the distinction between the two ends. You may want to make use of one as your positive and one as your negative. Generally the coating is a different color between the two or there may be textual content on one and never on the other. Hold monitor of this – whichever facet you employ for optimistic on your speaker, use it for constructive in your receiver. Crossing the 2 can cause injury, either instantly or sometime within the future. It might work this way but you do not need it to!
Connecting the speakers is easy enough. Entrance left to entrance left in your receiver, middle speaker to heart on your receiver, etc… Your rear audio system may be referred to as “Surround” or “Rear Surround” as an alternative of just “Rear”, but consider, you probably have a 7.1 or 8.1 channel receiver, “Encompass” could indicate aspect encompass speakers, not rear speakers.
Subwoofers
Your subwoofer goes to be somewhat extra complicated. There are a couple of other ways to do it and lots of variations of inputs/ouputs on the again facet of subwoofers. I’m going to go along with the most standard and efficient method first.
You will need a subwoofer cable for connecting your sub. If you do not have one or do not need to buy one, you’ll be able to substitute it for the standard purple or white RCA cable (or a pair, since they are normally linked; simply let the other cable dangle). It’ll work, but its really not the easiest way to do it. You’ll also need whats referred to as a Y adapter. On the back of your sub, there should be a left/proper enter (purple and white). You plug the Y adapter in to those connections after which your subwoofer cable (or RCA cable) in the other end of the Y (note: if you don’t have a Y adapter, just choose the left or right input to plug into).
Now, take the opposite end of your cable and plug it into your receiver’s
subwoofer preout. Hopefully you’ve got a powered sub, that means it gets plugged into an AC power outlet. All you’ll want to do now could be plug that in and your subwoofer is sweet to.
If you do not have RCA jacks in your subwoofer, or it only has speaker wire jacks (and its almost certainly not powered), you will want to attach it the old fashioned way. Your front left and right speakers will plug into your subwoofer’s ouput jacks instead of your receiver. You’ll then run speaker wire from the left and proper inputs on the subwoofer to your left and right speaker outputs on your receiver. This fashion, the subwoofer is powered by the receiver and will not work as well as a powered sub. You also take some energy away from your front speakers with this method. A good suggestion is to purchase a brand new, powered subwoofer with line in RCA jacks.
Connecting the Dots
You’ve got received the laborious stuff out of the way. Now end it up by connecting your TV, DVD, and cable/satellite tv for pc box. All the time try utilizing the most effective choices first. If your DVD
has HDMI and so does your receiver, use it. In case your DVD solely has composite, s-video, and component, use part video cable. When it comes to audio, you absolutely want
to make use of digital coaxial (jacks are usually orange) or fiber optic (often the jack is recessed into the unit and has a door on it; when the door is open, a purple gentle is seen). If you don’t use either of these two, you won’t get true surround sound! When all else fails, resort to composite (red and white) audio connectors.
Be aware: Look carefully at the connections on your receiver. All the things is labeled, like the primary set of purple, inexperienced, and blue component video inputs could be labeled “Comp 1″. If you’re utilizing composite audio cablesfor your sound, you may must plug them into the jacks that coordinate with “Comp 1″. This may not be clear by wanting at the receiver, so check with your receiver’s handbook to determine which video inputs use which audio inputs. Most frequently, you can configure them from the receiver’s inner menu utilizing the distant control.
On some receivers, all of the component video inputs, for instance, are linked to a single composite audio enter (often “DVD”), so when you join greater than one of the element inputs, you’ll be competing for sound when a couple of gadget is active. This is the reason you’d wish to configure the element inputs to use different audio inputs.
Your guide is the only approach to determine how to go about it. Composite video will usually match up to composite audio inputs with naming conventions like Video 1 -> Video 1, Video 2 -> Video 2, etc., however cables like element and DVI could not. You should also configure digital audio inputs to match up with the video inputs you are planning on using. For instance, in case you’re using a digital coaxial input (possibly “Digital 1″), and you employ part video, you’ll need to match “Digital 1″ with “Comp 1″. Once more, confer with your users manual for tips on how to do this.
