Introduction To Home Theatre

Today, for many people, watching a movie is something that takes place at home, not in a movie theatre. The introduction of DVD’s and projectors and sound systems targeted at the Home Cinema enthusiast, allows anyone to create a film experience that often beats what is on offer at the local cinema!

When it comes to budgeting for your home theatre, you have some big choices to make. It’s possible to spend anything from $1000 to $1,000,000 on a home cinema, although typically a good setup will cost no more than $3000. The key is to budget wisely, don’t spend all your money on a Projector while buying cheap speakers or your experience will suffer!

Typically, a Home Theatre setup will consist of a DVD (or nowadays a Blu-Ray) player, a Home Theatre Amplifier, a set of surround sound speakers, and a Projector and screen. Some people prefer to use an LCD or Plasma TV, but while these are good enough for TV programs, sports or video gaming, nothing less than a proper projector and screen setup will give you the real “big screen” feel you get at a movie theatre. When budgeting, don’t forget to include the cost of extras like cables, and seating, and even dedicated lighting and remote controls if you want them.

With the death of HD-DVD, Blu-Ray is now the only hi-def movie format, so the heart of you system should be a good quality Blu-Ray player. There are now plenty to choose from, with prices starting from around $300, but surprisingly, one of the best Blu-Ray players is a the Sony Playstation 3. Not only is it a very capable video games machine, but it’s video output is of a very high quality, and it benefits from very speedy menus and loading due to it’s powerful processors.

Your next purchase should be a Home Theatre Amplifier (Amp). Home Theatre amplifiers are different from Stereo Amplifiers, in that they can decode the sound formats used by DVD’s and Blu-Rays, and have outputs for 6, 7, or 8 channels. A good amplifier is a must, look for one that is powerful enough for your room, and can also decode the latest sound formats. Some amplifiers will also switch your video between multiple inputs and outputs, which can be useful if you want to hook up several sources to your projector and speakers.

Speakers should be chosen to match your amplifier. For home cinema the most popular setup is 5.1, where there are 5 main speakers, and 1 “subwoofer”, a speaker dedicated to producing very low “booming” sounds. If you want to feel every explosion or gunshot of a film, buy a speaker package with a high-quality subwoofer! The 5 normal speakers are placed around your seating position; one in front, one each to the front left and front right, and one each to the rear left and rear right. 6.1 and 7.1 systems are available with even more speakers, but 5.1 is good enough for most rooms.

Lastly, you will want a projector and screen. The models that are right for you will depend on your room size and the level of ambient light when you watch your films. In general, look for the brightest, most high-contrast model you can afford, and buy a model that produces at least a 720p image, although preferably 1080p.

Beginners Guide To Projectors

So you’ve decided you want a projector, but you don’t know where to begin? Don’t panic, in reality, there are only a few simple decisions you need to make, to know what projectors will be right for you. Before you begin, you want to decide whether you will be using your new projector for displaying movies, playing video games, or giving presentations. This will affect how bright or dark your viewing room is and what resolutions you need, plus things like connection options. Also work out where you want to place your projector relative to its screen.

To begin with, you will need to consider brightness and contrast. Most projectors have their brightness stated in two ways, Lumens and foot-Lamberts. Sadly the Lumen rating is not a really useful gauge of brightness, as it often does not take into account the viewing size of the final image or reduction due to normal rather than max usage. In dark conditions such as a dedicated home theatre room, look for a brightness rating of around 40 fL, and increase it depending on how much extra ambient light your viewing room will have.

Contrast is often a more useful measure of projector quality than brightness. A high-quality projector will have a contrast ratio of 5,000:1 or more, all though check to see if the projector uses a “dynamic iris” to help boost its contrast range. These work by restricting the light output in dark scenes, allowing the projector to produce “blacker blacks”. Many such projectors will also just quote “on/off” contrast, which is the difference between a full black and full white screen. A better measure is ANSI contrast, which uses a chequered test pattern, and measures the difference between the light and dark squares. This value will be unaffected by any dynamic iris, and is usually a lower value.

Next you need to think about the supported resolutions you want to display. The very best is 1080p,so called “full HD”, and will allow you to display Blu-Rays and other high-definition content properly. Most games and computer presentations will only need 720p or 1024×768 resolution, so if you won’t be primarily watching movies, save some money and go for a lower-spec model. 1080p and 720p are both 16:9 widescreen resolutions, whereas 1024×768 is 4:3, which is a more square standard used by many computer monitors and older TV’s. Consider the screen you will be displaying on. To get full use of the screen, make sure it’s resolution matches that of your projector.

Finally, make note of the “throw distance” of the projector. “Short Throw” projectors are designed to be placed closer to the screen and still produce a big image, whereas “long throw” projectors are the opposite. Also quoted will be the amount of zoom available, which will allow you to grow or shrink the image somewhat. Another useful feature on most projectors is lens-shift. This will allow you more flexibility in placing the projector relative to the screen by enabling you to move the image up and down or left and right by a certain amount without distorting the image.
