Communication Cables - Coaxial, Drop, UTP and Fibre Optic Cables

There are numerous types of Communication Cables available in the market today, but we depend on some types of Cables like Coaxial Cables, Drop Cables, UTP Cables and Fibre Optic Cables more often. These Cables are applicable in different types of data transfer in our day to day life.

Coaxial cable is called "coaxial" because it includes one physical channel that carries the signal surrounded (after a layer of insulation) by another concentric physical channel, both running along the same axis. The outer channel serves as a ground. Many of these cables or pairs of coaxial tubes can be placed in a single outer sheathing and, with repeaters, can carry information for a great distance.

HDMI Cable

PVC jacketed Bus Drop Cable is intended for use as drop cables from overhead busways and allows easy relocation of plant equipment.Resistant to oils, lubricants, acids, alkalies, ozone, water and abrasion. Individual grounds per conductor. Conductors, grounds and filler are cabled for flexibility then wrapped in a separator to aid strippability. Rated for use in wet or dry locations.

Unshielded Twisted Pair (UTP) cable contains 4 twisted pairs of wires, a total of 8 wires. The strands that constitute each wire will either be a single strand or multiple strands, usually referred to as solid or flex. Typically the solid is used to run through walls and ceilings and the flex is used to make drop cables (the cable from the wall plate to the desktop computer) and patch cables (the cable from the patch panel to the hub). Whether the exterior portion of the cable that contains the 4 twisted pairs, the jacket, is Plenum grade or Non-plenum grade is very important, it refers to the Fire Codes.The pairs of wires in UTP cable are colored so that one can identify the same wire at each end. Furthermore, they are usually color coded by pair so that the pairs can also be identified from end to end.

Fiber Optic Cables use light pulses to transmit information down fiber lines instead of using electronic pulses to transmit information in copper lines.Light pulses move easily down the fiber-optic line because of a principle known as total internal reflection. "This principle of total internal reflection states that when the angle of incidence exceeds a critical value, light cannot get out of the glass; instead, the light bounces back in. When this principle is applied to the construction of the fiber-optic strand, it is possible to transmit information down fiber lines in the form of light pulses.

RGB Cables

RGB cables are named so, because the plugs at the ends of the cables are color coded red, green and blue. There are a variety of RGB cables. All RGB cables are a type of component video cables. Component video cables are able to split video signals into three different signals. Two of the three signals control how much red and blue there is in a picture. They are called the B-Y and R-Y components. The third signal, called the luminance signal handles black and white information and controls the brightness of a picture. It is often called the Y component. Unlike composite cables, there is no compression of any signals. Because of this the depth of color and resolution achieved is superior to composite video and is even an improvement of S-Video setups.

RGB is still sometimes used on computers but is increasingly being replaced by digital formats that require digital video interface cables (DVI cables). Some of the many devices that are RGB input devices and use RGB cables and technology are color televisions, digital cameras and scanners. There are also several RGB output devices that are used very often. They include, computer and cell phone displays, television sets with a variety of display types such as cathode ray technology (CRT), liquid crystal display (LCD) and plasma display or LED display, video projectors, and the large screen displays called JumboTron that are used at many sporting facilities and entertainment venues.

HDMI Cable

RGB analog composite video signals must always be combined with some other signal in order to function properly. One of the ways this is done is called composite sync. In any type of display, the resolution is determined by the number of pixels that are arranged both vertically and horizontally on the display device such as a computer monitor or a television monitor. The number of vertical lines in the display is always fixed. The vertical lines are also often referred to as scan lines. However, conversely the number of pixels that are in between each vertical line can vary. The amount of pixels determines the horizontal resolution. Depending on the ability of the monitor or display output, the quality of resolution achieved can vary. In this type of setup, both the horizontal and vertical signals are combined on a completely separate wire. This type of synching is called RGBS. A true composite signal is achieved by utilizing four wires. They are colored red, green, blue and a plug for sync which is normally white or yellow in color. Another way to combine signals is called separate sync. In separate sync, the horizontal and vertical signals are each carried on a separate wire. This type of synch is used in RGBHV setups. Separate sync is common in VGA devices such as analog computer monitors. Separate sync requires five different plugs. They are color coded red, green, blue and either a combination of yellow and white, yellow and black, or gray and black plugs.

Cables to Connect Computer and Television Together

Online shoppers today are faced with a staggering variety of cable choices when trying to connect their PC to their TV. They may wonder which cables give them the best sound and picture quality, and may also want to know the various options they have to connect their TV and PC together. High Definition Multimedia Interface leads are by far the most common cable of choice in demand at present, but products such as the Toshiba Satellite L300 have a VGA 15 Pin D-Sub socket, and so a different cable type would be needed.

Connect PC to TV using the latest wireless technology

HDMI Cable

If your Desktop, Laptop, Tablet PC or Smartphone, has a USB port or 'socket', there is a multitude of devices available online which will allow you to stream both sound and video content wirelessly from your PC, provided that your Television has a HDMI (High Definition Multimedia Interface) input. Fortunately, nearly all High Definition (HD) TVs on sale in 2012 are retro fitted with a HDMI input, and every new 3D TV is equipped with a HDMI input.

Connect mini USB and micro USB PC to TV wirelessly

Some Laptops, Desktops, Tablet PCs and even Smartphones have mini USB or micro USB ports, and so to stream audio and visual content wirelessly from one of these devices, you would need a micro USB to USB (Type A) converter, or mini USB to USB (Type A) converter to use a Wireless PC to TV streamer.

Connect Apple iPad, iPhone or iPod Touch to HDMI High Definition Television screen

If you want to connect your Apple multimedia device to your TV monitor, you can do this by using an Apple 30-Pin Dock connector to HDMI (Type A) converter along with with a HDMI (Type A) 1.4 lead. This combination of adapter and cable is also compatible with the iPhone 3, 3G, 4, 4S and iPod touch.

The wide availability of product choice can only be seen as a positive thing for the consumer. Due to high competition, consumers have the power to demand ever-increasing levels of durability and transmission quality, at prices as low as 46p for a HDMI cable (the cheapest HDMI cable we have ever come across). It would be best to recommend any form of HDMI (High Definition Multimedia Interface) 1.4 cable from a trusted online retailer.

Are expensive HDMI cables better than cheap ones?

If you have just spent your hard-earned cash on a 42" High Definition TV, you may think that spending loads on a "top-of-the-range" HDMI cable will ensure better image quality, but it is widely regarded that around £9.99 is a sensible amount to spend on a HDMI cable (to strike a good compromise between value and quality), unless you require a cable of more than 3 metres. Longer HDMI cables tend to cost more than £10, but are surely a cost-effective alternative to connecting PC to TV wirelessly.

If you don't know your PC or TV connection type, use an online configurator to search for a PC and TV connection by Make and Model. If you don't know the Make and Model of the PC and TV you want to connect, you can also search by cable connection type. - Connect PC to TV

If your laptop lacks a HDMI input, but has a VGA input, you have two options:

Option one: Buy a VGA (Male) to VGA (Male) cable, a VGA to HDMI adapter set, a HDMI (Male) to HDMI (Male) cable, and a 3.5mm Mini Jack to RCA cable

Option two: If your PC also has a USB socket, use that instead and buy a Wireless PC to TV streaming kit

Option one will cost you nearly the same as the wireless PC to TV streamer, because the VGA to HDMI converter box will set you back at least 39.99.

Most wireless Computer to Television streaming kits are designed to work from a distance of up to 30 feet, so if you are planning to connect PC to TV wirelessly from a large distance, you should use a high quality HDMI cable, VGA cable and HDMI to VGA adapter, along with a 3.5mm Mini Jack to RCA lead.

You will need a 3.5mm Mini Jack to RCA cable when connecting using VGA because VGA does not carry audio signal. VGA cables must be used in conjunction with a 3.5mm Mini Jack to RCA cable when connecting Computer to Television.

How to connect Apple Mac or MacBook to HD TV

If you have a recent Apple MacBook or Mac Desktop, you are likely to have either a Mini DisplayPort input or Apple Thunderbolt input. Most new Mini DisplayPort adapters and cables are compatible with Apple Thunderbolt for connecting Computer to Television, so if you are planning to connect your Mini Displayport or Thunderbolt equipped Apple multimedia interface to your 27" Apple LED screen, you can use a Thunderbolt cable. Like HDMI cables, Thunderbolt also carries audio signal.

If you want to connect your Apple Thunderbolt or Mini DisplayPort (input) Computer, Desktop, Laptop, Netbook or Tablet to your HDMI High Definition Television, you can use a Mini DisplayPort to HDMI converter, or Apple Thunderbolt to HDMI converter.

Some new televisions come equipped with a DVI port (either a DVI-Integrated, DVI-Analogue, or DVI-Digital). DVI cables do not carry audio signal, so need to be used in conjunction with a 3.5mm Mini Jack to RCA cable.

Hava HD Wireless Setup Tutorial Xbox 360 PS3 Tube. Duration : 4.92 Mins.


Here is a tutorial I put together featuring the Hava HD Wireless. This device is for capturing gaming through standard definition cables (RCA or composite cables) or component cables (HD). You can play on either a standard definiton tv or an HDtv. Hava also offers other recording devices to capture your gaming (and record TV), but I owned the HD Wireless so that is what this video covers. (Hava says they no longer makes this product, but it's still available on their website for 9.99: www.myhava.com You could also use the Hava Titanium HD WIFI, which does the same thing as the HD Wireless, "but offers more flexibility" for 9.99: www.myhava.com This also connects wirelessly but is a newer model. If you do not want to spend the extra money for the WiFi version, you may want to opt for the Hava Titanium HD: www.myhava.com It lists for 9.99 after the instant savings from Hava.com. It is a very reasonably priced device for capturing and should be considered for anyone who wants to capture standard definition on both standard tvs or HDtvs. Please leave any comments or questions, and I will do my best to answer them promptly. You may also email me at Wepeeler@aol.com. Good luck! Ultra Special thanks to Rogan Sarine!!!

HDMI to Cable - Running Your HDMI Cable to Your Cable Box

There are a few things to consider when running an HDMI to cable boxes in your home. Many cable providers these days will provide you with a high-definition cable box that has HDMI port located on the back. Of course, you will need to sign up for the HD package through your cable provider first. Next, you will need to purchase your HDMI cable.

The first thing to consider when hooking up your HDMI to cable is the length between the cable box and your television set. Many people like to put all of their components in a room or closet and run their cables through the wall. This will provide you with a sleek and clean set up. However, you will need to run a receiver in order to use remote controls.

HDMI Cable

When running HDMI cables through the wall, it is recommended that you get a cable that is CL2 rated for in-wall installations. This will ensure that you don't cause an electrical fire, and will allow you to pass your inspections if necessary.

The Next thing to consider is the thickness of the HDMI cable. Most HDMI cables will indicate the thickness of the cable using the American Wire Gauge (AWG). The lower the number AWG, the thicker the cable is. It is recommended that you use a 22 or 24AWG cable for long runs because you may lose your HDMI signal with a thinner cable. A 28AWG HDMI cable will work fine for lengths 15FT and under.

It is also important that you consider the price of the HDMI cable before running it to your cable box. If you feel that the HDMI cable you're looking at is overpriced, it probably is. Cheap HDMI cables can be found at a very low price and they will not make a difference in the quality of your picture. All that matters is whether or not the signal gets there. Many people are paying for the brand of the HDMI cable and not the actual cable.

You should now have a better understanding of how to run HDMI to cable boxes. Hope you enjoy your television shows in high definition!

Why Do I Need CL3 Or CL2 Rated Cable For in Wall Installations?

Anyone who has remodeled a home or has experience in construction knows that when it comes to a home, there are many rules we have to abide by when doing modifications. This comes into play when we want to install a nice home entertainment system in our home. Any wiring or cables going into our wall have to meet NEC specifications.

One of the most common cables being run through walls lately has been HDMI cables. Most people don't know that we can't simply go to the A/V store and buy any HDMI cable to put in our walls. The NEC requires that signal cables like HDMI cables need to have at least a CL2 rating for installation within homes in the United States. For industrial applications cables meeting a CL3 requirement must be used.

HDMI Cable

The main benefit of using cables like these is that they will not produce toxic fumes if the home or building catches fire. They are also designed not to make a home fire situation any worse. Many off the shelf HDMI cables that aren't CL2 or CL3 rated do not have this rating and when exposed to fire can emit dangerous fumes or cause a fire to grow more rapidly.

Because of these hazards its important to select a quality CL2 or CL3 rated HDMI cable for your home theater installations. Running HDMI cables through walls can be a time consuming and expensive task, make sure you select a high quality cable so the job only needs to be done once! Also check with your home owners' association and local building inspector to see if they require you to get permits for home theater installations.

Hook Up A Receiver For Your Home Theater

What is a Receiver?

A receiver is that big, heavy thing that you plug your speakers and other components into (like a DVD player, TV, CD player, Xbox, PlayStation, iPod, and etc.). Its the "brain" of the show, really. The idea of connecting all your components to a receiver is the concept of audio/video switching, allowing you to switch to different video sources (like TV, DVD, camcorder) on your TV
and thus changing the audio source accordingly - all without touching anything but the receiver.

HDMI Cable

Of course, the main purpose behind audio/video switching with a receiver is to drive audio to external speakers, like 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), several video inputs, and even HDMI inputs. You could plug your Xbox, Plasma, and DVD player into the receiver and use one remote to switch between all the different video sources (games, TV, DVD video) and have your speakers pump out surround-sound. Let's start with inputs and outputs. If you don't understand something, read through the entire How-To as most of it will be explained in detail.

Keep in mind that a receiver is the hub of your entire home theatre, so this How-To will actually guide you through the basics of connecting your complete home theater.

So what the heck is all this 'stuff' on the back of your receiver?

I'm going to go over just about anything that you would find on the back of your receiver. The one I'm basing this guide off of is a Harman Kardon AVR-247 I'm going to start from the top left of the unit and work my way to the right, then I'll start 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 don't have to plug your antennas in, but if you'd like AM/FM reception through your speakers, you'll want to go ahead and do that. These are standard connections, so if you lose one of your antennas, just go buy another for a few bucks.

You've probably heard of composite video. Its a very basic video connection used by most any component (TV, DVD, VCR especially). Its common and its cheap. As such, its very low quality.
Composite uses an RCA cable for video (yellow) and two more RCA cables for audio (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 picture. You lose a lot of sharpness, and the color begins to degrade from the original source. Its useful when you need the extra input or the device you're connecting only has composite video. Otherwise, use something else, like component video. Sounds similar; very different.

S-Video is next in line after composite. It uses a different type of connector (five pins in a circle) and gives you marginally better video quality. It is also a video-only cable, so you'll need to plug in audio separately. In this case, you'll probably use a pair of red and white RCA cables for your audio inputs.

Next up: a ton of composite audio inputs. These inputs use left channel and right channel RCA cables, typically red and white. They look just like the yellow composite video cable, and you could even use them for video and the yellow for audio, but let's keep the color scheme how it is ;) Composite audio is the bottom-of-the-barrel in audio. Its perfectly fine for most use, but if you're looking for high quality surround sound, you don't want composite. Game systems, like the Wii or Xbox, and very basic DVD players are a perfect match for composite audio.

The same goes to VCRs, CD players, and anything that only has a composite audio output. Plus, if you don't have surround sound, or your receiver is only two channels (2.1, stereo sound), you won't be able to use anything but composite audio. Note that there is a composite audio input under each composite video input so that it is easy to match them up. Plug them in the wrong inputs and you won't get sound when you're on that particular video input.

Here we have one of the least-used features of a modern receiver: 6 (or 8) channel direct input. This is only used for two purposes: SACD or DVD Audio. SACD is an acronym for Super Audio CD. It is a proprietary audio format developed by Sony for special CDs that are recorded in 5.1 surround sound. That means you need a CD or DVD/CD player that supports SACDs, a receiver with SACD support (as in the picture), and of course Super Audio CD's. DVD Audio is the same idea, different brand, different media (its a DVD, not a CD!).

DVD Audio discs are special DVDs that are recorded in 5.1 surround sound and can only be played by devices with support for them. These CDs go all the way up to 7.1 surround sound, meaning you would need to have two front, two rear, two side speakers and a subwoofer to enjoy full 7.1 surround sound. Most receivers support up to 7.1 now but you won't find DVDs with that kind of capability for movies. 5.1 surround is still the defacto standard, so don't run out and buy more speakers any time soon.

You could skip this next little item because it is unique to this brand of receiver (Harman Kardon). The Bridge" is a proprietary connection they developed for you to connect
an iPod. You need to buy a separate component that includes a docking station and special cables to connect the iPod. It fully integrates with the receiver, displaying
menus and songs on the front LCD screen of the receiver. This allows you to easily pump your tunes through your speakers, whether it be stereo sound or full surround sound.

Of course, the music on your iPod is stereo sound, so the best you can get is simulated surround sound or stereo surround; the same music playing in the front two channels
is put through the rear and center channels. Some receivers do this more intelligently than others, but more on that later.

Here we have our high-end sound inputs/outputs. Basically the same performance wise, you have fiber optic connections (with the square shape) and digital coaxial (just like an RCA cable).
Both of these are 100% digital, whereas composite is analog. The only way you can get true surround sound from any source is by using one of these connections (or the SACD/DVD Audio option)

Almost all DVD players these days have either optical or digital coaxial outputs (sometimes, both). Many high definition cable and satellite boxes also come with these
connections so you can enjoy 5.1 surround sound on high definition channels. Choosing between the two, there's really no different in audio quality, so feel free to use
what you'd like (or what you're forced to).

I don't think I need an image for the next plug. Its a pair of power inputs. One is for powering the receiver, the other for whatever you'd like. This way, when you turn
on the receiver, you give power to the other device (be it a DVD player, CD player, cable box, whatever). I don't necessarily recommend this unless it specifically suits
your needs. It is useful if you're running low on outlets, of course.

Something else you'll never use: D-bus RC-5 input/output. This is used for infrared remote controls to take over your home theater system. Honestly, its not something any of us will ever use. Some of the real high-end junkies might be using something for it, but I've never even come across a device that uses this technology. Stick to the remote that came with your unit, or buy a quality universal remote control. There's no 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 could get an infrared transmitter to latch on to the front of it. This transmitter would hook up to another device somewhere in your room that will accept signals from your remote control. The receiving device then transmits the remote's commands to your receiver (via the transmitter you've attached to the front over the regular infrared transmitter).

Pre-outs , located right under the Remote in/out. Pre-outs are used when you'd like to add an amplifier to your system to boost the power (and hence volume/audio quality). Average
users will not use this for anything but the subwoofer preout. You'll want to run a subwoofer cable from your subwoofer to the subwoofer pre-out to provide it with
the right frequencies. This is the proper way to connect your subwoofer to your surround sound system. The other inputs won't be used unless you plan on adding
an amplifier. This is highly unnecessary for home use. You might add an amp if you're trying to fill a room the size of a small house with enough sound, but you're not, right?

Here we finally get to the meat of the system: the speaker inputs! Harman Kardon receivers use bind posts for connecting speakers, as seen in the picture. They
work by being loosened up as your turn 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 probably won't loosen up on itself over time. Other brands may use other types of connectors, but bind posts are very common.
You might have been able to tell this is a 7.1 channel receiver because of the speaker inputs.

You've got room for 2 front left and right speakers, 2 rear left and right speakers,
a center channel, and two left and right "surround" channels which are placed somewhere in between your front and rear speakers ("side surround", or 7.1). If you have enough
speakers, you can go ahead and plug in those extra 2 side ones, but they won't play any sound at all on a 5.1 DVD. You would need a DVD that supports 7.1
surround sound, and at this time, there just isn't a market for it. CDs will gladly blast stereo surround through all 7 speakers, though, so for some larger rooms, that's an
advantage.

Our final set of connectors for this receiver: component video . The best video you can get next to composite or s-video. You'll notice its a set of three cables (all for video),
usually Red, Green and Blue. Don't think that's what the cable does, though - it separates the video signal by luminance and two separate color channels. In the past, component
did it in fact represent R, G, B (splitting the primary colors in transmit and recombining them at the destination device), but that is not used in current component video
connections. Component video can carry high definition signals, all the way up to 1080p, so it is the most cost effective and readily available high definition input.
Not seen on this receiver are DVI and HDMI, the two all-digital video connections.

HDMI is the newest, fastest, sharpest video and audio connection available today. Its the only cable that can carry audio and video in one - not to mention, in high definition.
HDMI must be supported by the source and the display you're connecting it to to use all of its features. Not all DVD players, cable boxes, or receivers support both
audio and video in HDMI. Its becoming more and more of a standard now to support both. The advantage is clear: less cable clutter, higher quality audio and video. You can get up
to 1080p high definition video and 7.1 surround sound through an HDMI cable. Newer cable and satellite boxes, DVD players, high definition DVD players, and more expensive receivers
support the full capability of HDMI. Its the best you can get as all-digital goes.

The last connection for this article is DVI. DVI is also all digital like HDMI, but it cannot process audio signals. HDMI may provide a technically superior image,
but I don't think anyone could tell the difference. DVI supports high definition video all the way up to 1080p, just like HDMI. Its being used less frequently now,
but if you've bought a new computer or video card for your PC recently, it probably has a DVI (or two) port on it. Most computer monitors use DVI now and video cards
have followed suit. HDMI is edging its way into the PC market, but its dominance is seen in the home theater arena.

Now that you've familiarized yourself with common connections, let's plug it all together.

This part of the receiver How-To is going to guide you through hooking a 5.1 surround sound system(5 speakers and a subwoofer) with a high-definition TV, a high-definition cable or satellite box, a DVD player, and a 5.1 receiver.

Your TV & Components

Where you put your TV is dependent on how large it is, how large your room is, and where you will be sitting. If its 50 inches, don't sit more than 10-15 feet away; but no less, either.
A 60" set is perfect for 12-20 feet. If you have a 32 inch set, try to sit no farther than 8-12 feet away. Your receiver, DVD player, cable box, and other components should obviously be close together, but don't place them physically on top of each other. They all get hot, especially your receiver. If you have no other choice, slide a thin piece of plywood between the components to help dispense the heat.

Lay Out of Speakers

The first step is to lay out your setup. Different rooms call for different locations for your speakers and subwoofer. If your room is a typical rectangle, go ahead and place your two front left and right speakers somewhere flush with the television on that side of the room. Your left speaker goes toward the left corner, right speaker toward the right corner. Don't bother with speaker wire yet (unless your speakers come with speaker wire attached already; in that case, just let them dangle for now). Note that which speaker is left or right is solely dependent on how you connect them to your receiver. Your speakers aren't actually designated "left" or "right".

Depending on how you acquired your speakers, your front speakers could be larger than your rear speakers. That's how you know they're for the front. Otherwise, all your speakers are the same shape and size, and you can use each for any purpose.

One exception: the center channel. Usually, a center channel is much shorter and wider than your other speakers. It should only be used for the center channel. Sometimes, all 5 of your speakers could be the same, usually on a very inexpensive setup. You can use any of these speakers for any purpose.

Your center channel should always go either directly on top or under your television set. However you have to do this, get it done! It's not called the center channel for nothing, you know. Any movie will pump out almost 90% of the voices you hear and a majority of the rest of the sounds through the center channel. It is a vitally important component to your surround sound setup.

Your subwoofer should always be on the floor. If it is impossible to place it on the floor, get it as close to the floor as possible. Placing it behind objections or in closets will diminish its effects. In a perfect setup, the subwoofer would be on the floor close to the TV (perhaps off to the left or right) in 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 speaker itself).

When it comes to finding a good spot for your speakers, you might want to mount them. You can usually buy compatible speaker mounts online or in stores. You can also
use existing shelving, buy some shelving, or place them on tables or other objects. No matter how you do it, try to keep the speakers as close to ear level as possible. A speaker mounted at the ceiling of your room isn't going to give you the optimal aural experience.

The last thing to keep in mind about layout is speaker wire. You'll probably need at least 100ft of speaker wire, but you'll often find yourself using much more if you
try running wire through your ceiling, under carpeting, up through the basement, or around objects to conceal it. Take measurements and buy at least 10% more wire than
you think you need. You'll probably use it!

Cabling

You need to know the different kind of speaker wire available to you before setting up your home theatre. If you bought an HTIB (home theater in a box), it probably came with 100ft of horribly cheap speaker wire. You don't want that! Do yourself a favor: buy some high-quality, 14-guage speaker wire. Anything higher than 14-guage is just to thin and will be susceptible to interence, quality loss, and poor quality over longer distances. Fourteen guage is a good thickness and suitable for most home theatres. Make sure its also not too thick - some speaker wire simply will not fit 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 will not accept a standard speaker wire. You'll need to use either the Sony-provided speaker wire, take the ends off of Sony speaker wire and put it on your own, or buy some of these special connectors from Sony directly to place on your speaker wire. My recommendation? Avoid any receivers with non-standard speaker wire posts/jacks/connectors. Look for bind posts or other jacks that allow you to slide in and clamp down on a typical speaker wire.

Once you've got your speaker wire sorted out, you'll have to do some cutting and stripping if you opted to purchase your own. This is way easier than it sounds, so don't worry!

Measure out each length one at a time, cutting the speaker wire with either really great scissors or a sharp blade. Now you need to strip the ends of the wire. Use either a stripping tool or plain old scissors. You can place the scissors on the cable and gently apply some pressure as you twist the scissors around the cable, carefully slicing into the plastic coating. Eventually, it'll get weak enough that you can just slide it off by tugging on 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'll need to use one as your positive and one as your negative. Sometimes the coating is a different color between the two or there is text on one and not on the other. Keep track of this - whichever side you use for positive on your speaker, use it for positive on your receiver. Crossing the two can cause damage, either immediately or sometime in the future. It might work this way but you don't want it to!

Connecting the speakers is easy enough. Front left to front left on your receiver, center speaker to center on your receiver, etc... Your rear speakers may be referred to as "Surround" or "Rear Surround" instead of just "Rear", but keep in mind, if you have a 7.1 or 8.1 channel receiver, "Surround" may indicate side surround speakers, not rear speakers.

Subwoofers

Your subwoofer is going to be a little more complicated. There are a few different ways to do it and many variations of inputs/ouputs on the back side of subwoofers. I'm going to go with the most standard and efficient method first.

You will need a subwoofer cable for connecting your sub. If you don't have one or don't want to buy one, you can substitute it for a standard red or white RCA cable (or a pair, since they are usually connected; just let the other cable dangle). It will work, but its really not the best way to do it. You'll also need whats called a Y adapter. On the back of your sub, there should be a left/right input (red and white). You plug the Y adapter in to these connections and then 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 other end of your cable and plug it into your receiver's
subwoofer preout. Hopefully you have a powered sub, meaning it gets plugged into an AC power outlet. All you need to do now is plug that in and your subwoofer is good to.

If you don't have RCA jacks on your subwoofer, or it only has speaker wire jacks (and its most likely not powered), you'll need to connect 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 right inputs on the subwoofer to your left and right speaker outputs on your receiver. This way, the subwoofer is powered by the receiver and will not work as well as a powered sub. You also take some power away from your front speakers with this method. A good idea is to buy a new, powered subwoofer with line in RCA jacks.

Connecting the Dots

You've got the hard stuff out of the way. Now finish it up by connecting your TV, DVD, and cable/satellite box. Always try using the best options first. If your DVD
has HDMI and so does your receiver, use it. If your DVD only has composite, s-video, and component, use component video cable. When it comes to audio, you absolutely need
to use digital coaxial (jacks are usually orange) or fiber optic (usually the jack is recessed into the unit and has a door on it; when the door is open, a red light is visible). If you do not use either of these two, you won't get true surround sound! When all else fails, resort to composite (red and white) audio connectors.

Note: Look closely at the connections on your receiver. Everything is labeled, like the first set of red, green, and blue component video inputs might be labeled "Comp 1". If you're using composite audio cablesfor your sound, you'll need to plug them into the jacks that coordinate with "Comp 1". This might not be clear by looking at the receiver, so refer to your receiver's manual to figure out which video inputs use which audio inputs. Most often, you'll be able to configure them from the receiver's internal menu using the remote control.

On some receivers, all the component video inputs, for example, are linked to a single composite audio input (usually "DVD"), so if you connect more than one of the component inputs, you will be competing for sound when more than one device is active. This is why you'd want to configure the component inputs to use different audio inputs.

Your manual is the only way to figure out 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., but cables like component and DVI may not. You should also configure digital audio inputs to match up with the video inputs you're planning on using. For example, if you're using a digital coaxial input (possibly "Digital 1"), and you use component video, you'll want to match "Digital 1" with "Comp 1". Again, refer to your users manual for how to do this.

Watch Satellite TV on PC, TV or Cable TV

Watch satellite TV on PC, TV or cable TV? This is a question of choice but not on equal grounds since each have its strengths and weaknesses. According to a national wide survey, an average American probably spends more than 16% of his time in an entire year watching TV. This translates to about two months in a year which is more than half the time we spend on sleeping. Another staggering fact is more than two-thirds of American homes own more than three TV sets. TV is part of American culture. Discover what the differences are to help you decide whether to watch satellite TV on PC, TV or cable TV.

What are some of the differences? Should you watch satellite TV on PC, TV or cable TV?

HDMI Cable

1. Locality and Accessibility

Cable TV tends to be well-received in built-up areas since it is not affected by terrains and weather. However, in places where cable technology has not reached, such as rural areas or some suburban districts, satellite TV is their choice. In fact, you can set up a satellite dish system to watch satellite TV on your TV from any part of the world so it has a worldwide appeal. Where you can have internet access, you can watch satellite TV on PC readily.

2. TV Reception

You should not have any problem to watch satellite TV channels with clarity as long as your satellite dish system is set up for clear line of sight with the satellites. High rise buildings are ideal places for such systems as the satellite has full view of the skies. Needless to say, cable TV is able to receive and display TV channel feeds with a certain degree of clarity. However, since the reception of satellite dish system depends on external conditions such as weather, it may be less reliable during different seasons of the year. Fortunately, you can overcome this if you watch satellite TV on PC. Watching PC satellite TV is not constrained by weather or nature elements since they receive their feeds via internet connections which is a highly reliable media portal.

3. Variety of TV Programs

Satellite TV is a clear winner in this. Since it is made to receive free-to-air broadcasts, you can practically watch any channel as long as your satellite dish system can cover it. Nowadays, you can even watch satellite TV on PC if you prefer not to touch a satellite dish. Even though cable TV has been working hard to secure more channels for their subscribers, it is still pretty self-limiting in the number of TV channels it can offer. With satellite TV, you get to watch worldwide TV channels from any country and in any language.

4. TV System Installation

When you watch satellite TV, there are in fact three options. Either you build your own satellite dish system to receive free-to-air broadcasts or you can take advantage of free equipment installation provided when you subscribe for monthly satellite TV program packages with the service providers. The third option which is a new one is to watch satellite TV on PC using software application and internet connection. This is simply the easiest way to watch satellite TV.

5. Pricing

Satellite TV has an unfair advantage over cable TV in this aspect. Cable TV providers have to pay heavier levies charged by the state governments since the infrastructural makeup is more complicated and intensive than satellite TV providers which are light in infrastructure. Capital costs for cable TV companies are higher and with the advent of digital TV becoming the next big thing, it is a matter of time when they have to upgrade those million miles of ground-embedded obsolete cables. This is why satellite TV providers are able to charge less for more. In fact, if you watch satellite TV on PC, you can do away with monthly subscriptions and expensive Do-It-Yourself (DIY) style dish systems since you only pay once for the PC satellite TV software.

So I certainly hope this article can help you in making a choice between satellite or cable TV.

CAT5 vs CAT5E vs CAT6

Here is our opinion on choosing the right category of network cable:
Cat5 = If you plan on running at most 100 Mbps Cat5e = If you plan on running at 1000 Mbps (1 Gbps) Cat6 = If you plan on running at 1000 Mbps (1 Gbps) or more. Cat6 is better if you are in areas that have lots of interference like near power lines, lights, manufacturing equipment, or a long distance 1000 Mbps (Gigabit) run. We advise that you run at least Cat5e or Cat6 cable in the walls Cat5e are great for patch cables from the patch panel to the switch or from the computer to the wall jack We very rarely use Cat5 cable anymore. For most applications the CAT5E 350MHz network cables are best. They will run up to 1 Gig and are not as expensive as CAT 6 cables. CAT 6 cables are great for "future proofing" your installation. They are rated to carry network speeds above 1000 Mbps (Gigabit). CAT5E 100MHz are rated to only run up to 100Mbps networks but are inexpensive.
The above statements are the opinion of the Networkcablesonline.com and do not represent the solution for every situation. There are exceptions to these statements and a professional should be consulted prior to making a major network cabling decision. Please visit http://www.networkcablesonline.com for more information about CAT5, CAT5E, and CAT6 cables. [http://www.networkcablesonline.com/network-cables-c-59.html]

Troubleshooting your Cable Box

Unless you've recently moved from Alaska to Texas and you're feeling a little homesick, chances are that the last thing you want to see when you turn on your TV is snow. Combine a snowy screen with that loud, obnoxious static sound, and you've got a problem on your hands. Fortunately you don't have to be techie to fix your cable box - just follow these simple troubleshooting steps to get picture back in no time.Cable Box Basics

Make sure your cable box is plugged in. I know that sounds silly, but after troubleshooting these things over the phone professionally, you can trust me on this one. Save yourself the time and embarrassment of calling a professional just to have them tell you to plug it in. That goes for the rest of the essential equipment as well (i.e. TV, VCR or DVR if you're running the signal through one, etc.). It wouldn't hurt to make sure the TV is on the correct channel - usually channel 3 or 4 or one of the input channels.

HDMI Cable

Make sure all the cables are connected. Even if you're TV and cable box are both turned on, you won't see a picture unless they are connected. Check each connection to ensure it is tight and that none of the wires or connecting pieces is damaged. Also check to see that the connections are all correct - meaning, video and audio should be going out of your cable or satellite box to your TV "in" ports. The signal should follow a logical path. If the connections are correct but you're still not seeing any picture, replace the cables to see if that solves the problem. If you're running the signal through a DVR or VCR and having problems, skip the middle man and plug the cables straight from the box to the TV. If you get a picture you know you're problem is in the VCR.

After making sure everything is on and the cable connections are all correct, try rebooting your system. Each company's receivers have different methods of rebooting, but one fairly universal way is to unplug the box for 10 to 20 seconds and then plug it back in. Do not just turn the box off and back on again - you'll need to actually pull the plug out of the wall and then put it back in again. Once the cable box is plugged back in, turn the power on and cross your fingers. If you're still not receiving any picture, unplug the receiver again for up to one minute and then plug it back in. This may be tedious and time-consuming, especially when you're missing the fight of the year or the Super Bowl, but give it the full minute - you'll spend less time doing it yourself than you will waiting for a repairman to come out and fix it.

Fuzzy Picture or Sound

If you are getting a picture but no sound; or sound but no picture; or a fuzzy picture or sound, recheck the cable connections to make sure they are tightened and that the wires or connecting pieces are undamaged. Poor picture or sound is typically caused by one of three problems: poor wire connections, signal interference, or TV settings.

Going outside to make sure nothing is interfering with your signal will help with the second problem. Of course, if you have underground cables there is not much you can do about making sure they are clear of interference (that's read, "Your neighbor cut through it while gardening"). If you have a satellite dish, know that excessive rain or snow buildup on the dish can cause signal interference. Use caution when checking your dish, especially if it is on your roof or some other hard-to-reach place around your house. The installer should have verified that no trees or other objects would interfere with your signal from the satellites, but take a quick look around to see if new foliage is blocking the signal. If it is not on your property, do not cut or remove anything without prior permission from the property owner.

Finally, adjusting your TV settings can help when you are receiving a clear signal and all the connections are fine. Horizontal and vertical settings are the adjustments that most often need to be made, but consulting your owner's manual can give you a better indication of other settings that can be tweaked.

Troubleshooting requires patience, so make some lemonade, roll up your sleeves, and get started. If none of these suggestions work (9 times out of 10 they will), contact your service provider. They may have additional troubleshooting steps or resources they can make available to you to get your cable or satellite TV up and running.
