Understanding Home Theater Systems

joediv — Thu, 28 Jan 2010 12:19:26 +0000

First let’s discover what it is that makes a home theater different and more desirable over the performance of a standard television. When you go to the cinema the sound is much better than at home this is because speakers are placed around the cinema not just at the screen and this results in what is called surround sound. At home the speakers are built into a television and no surround sound effect is achieved and the purpose of a home theater system is to allow us the sensation of surround sound in our own homes. This is achieved by using various speakers placed around the room that provide the required effect. Ideally a good system will comprise of a minimum of two speakers in front of where you sit and again at least two more speakers behind or to the side of your seating. The sound is separated into channels that are sent to each loudspeaker with each channel being different to give movement to the sound, an example of how this works is that of a plane passing overhead the sound would start low at the front only and gradually get louder and as it reached you the sound would come from all the speakers and then only from the rear. The same applies to sound that would come from an object at a particular side of the screen if the object was to the left then the left speakers would produce that sound or on the right then the right speakers would produce the sound. The center front speaker acts to balance the sound produced by the left and right speakers to give even better quality sound reproduction and this is why systems with more than two front speakers are much better than two speaker systems.

Splitting the sound signal into channels for your home theater speakers is done by a device called a receiver which can also be called an audio/video receiver and it’s this unit that does all the work involved in transferring any input signal into vision for your screen and sound channels for your surround sound speakers. The receiver depending on which you buy will be able to facilitate various input devices which can be connected simultaneously and chosen via the receiver’s control panel or remote. These devices can include VHS recorders, DVD players, Blu Ray players, games consoles, satellite TV, sky and any other input that could be used for a television. The receiver will then take the input signal of your choice and convert it into two output signals one which is a visual signal to go to your viewing screen and the other will be an audio signal. The audio signal from the receiver will be split into surround sound channels and amplified before leaving the receiver to go to the respective speaker position. So a good home theatre system would have at least five speakers three of them front speakers and a receiver that is capable of handling all the inputs that you would require of it.

Projector Buying Guide: What To Look For In A Home Theater Projector

joediv — Thu, 28 Jan 2010 12:14:23 +0000

Are you looking for a projector but have no idea what you’re doing? Do you want to be the talk of your town and have the envy of all your friends every time they see your home theater projector? Are you on a budget and want to find the best projector without spending a fortune? You’ve come to the right place because the Projectors Buying Guide will show you exactly what to look for in a home theater projector! So what are you waiting for? Read on to find the information that you need to be giving the best presentations and watching your favorite films on the big screen – right in your own home!
How Big Should It Be
Home theater projectors usually aren’t that big. A good projector should generally be between 5-7 pounds, be able to fit under a bed, and come in a carrying case. It should not be a massive machine like those old clankity projectors that you remember from high school – the ones on that little cart and the teacher would write on the sheets of translucent paper. No, modern day projectors are much better and are even half the size of most PC towers.
Should It Make A Lot of Noise
Your projector probably will make some level of noise because the fan on the inside of the machine has to spin really fast in order to keep the projector cool. If it overheated, you can say bye-bye to Mr. Projector. Have you noticed how at your computer desk, you can hear a slight high pitched sound coming from the computer? That’s the fan – you probably won’t hear anything louder than this coming from your projector and at many times, you will hardly notice it.
Features
Be sure to get a projector in which you can adjust the lens in order to have ultimate viewing pleasure. Also make sure that you have a bright lens that has a high level of lumens and a high resolution. This is to ensure that you can get maximum quality from your projector as most computers run on higher resolution these days. If your projector does not meet the requirements of the computer that you’re using, the projector will automatically compensate by making the picture a little bit smaller. Normally, you won’t even notice this, however, it might make smaller objects in the film even smaller.
Those are the basics and should get you by when you’re out shopping for your projector. Projectors can range anywhere between $500 and $3000, but a projector on Ebay that costs a good $500-$600 will be more than enough to meet all of your requirements. The more expensive brands are just glamour and un-needed quality – like when you buy a new computer and it has 500 GB of hard drive space. You’ll never use that much. So be smart, be safe, and enjoy your new home theater projector.

Optoma HD70 Home Projector Review: Affordable Home Theater Projection

joediv — Thu, 28 Jan 2010 12:12:53 +0000

The Optoma HD70 is a wonderful addition to any home. It’s small, portable and, best of all, lightweight. It’s not excessibly branded with giant banners or stickers and can fit in any drawer or under any bed and be ready for action whenever you desire top of the line movie quality for your Friday night date, Sunday afternoon football game, or just an average weekday in bed. When it comes down to high performance and sleek design, the Optoma HD70 is the projector for you.
The Optoma HD70 is great at adjusting the size of your image so that your movie will always delight you in the best possible manner. This mechanic work of art will project a 100″ image from 11.5 feet to 13.8 feet away. When watching a movie on your Optoma HD70, as with any projector, be sure to set your projector slightly behind the seating area, if possible, as this will help to minimize any noises or heat coming from the machine.
The HD70 is rather good at positioning the image at an angle of the lense. For example, if you have your projector sitting on a desk or table, you can adjust the lens so that the movie will appear higher up than the projector itself. This will make your video seem more grand and inspirational than what your average television is capable of producing. You could also mount your projector on a ceiling (like how your fan is positioned in the center of the room) so that your movie will be slightly lower than the projector. This will provide the same effect of setting your projector on a desk or table while minimizing sound and heat distractions, although it is a rather large project to do and will cost extra. If you’re interested in mounting your projector on a ceiling, a quick search engine listing will display all that you need to know on this subject.
The Optoma HD70 is an important projector in that it provides the viewer with an opportunity to see the best at affordable rates. While it does not quite reach the capabilities of the Optoma HD72 in pure image quality, it delivers a high class image at irresistable prices. If you’ve never owned a home theater projector before, the Optoma HD70 would be an excellent choice to start your new life of movie quality that you’ve never seen outside of a movie theater before. There are some decent projectors out there for lower prices, but when you put this much quality into the budget bracket of the Optoma HD70, it’s hard to resist.

The modern day digital screens are highly precise that you can watch every color and every pixel clearly on the screen. You will see sharp images and high color quality with these digital screens.
