Home Theater and Speaker Systems
No home theater system is complete without a good speaker system. Ideally, the surround sound should be Dolby 7.1 or at least Dolby 5.1. If you are going to spend the money on a great home theater system, it makes little sense to "cheap out" with the speakers and audio system, since after the picture, the SOUND is the other component that lights up your internal sensory preceptors as you are enjoying your system.
You can even go the extra mile with your surround sound system if you want to do everything, and use the "bass shaker" attachments that are available with some systems. These gadgets attach to your recliner or sofa, and when a scene comes on with an explosion or car wreck, these gadgets actually SHAKE the recliner or sofa, adding to the realism of the movie.
My suggestion is that make a list of things for yourself, or maybe even a spreadsheet that your take with you when shopping around. Put a column for features that you have to have as opposed to the want to have features. And definitely shop around for your entertainment center. Make a budget for yourself that you a will not go over by even a penny, no matter how much a particular piece of media is screaming 'buy me, buy me.'
Watch for certain systems you like to go on sale. Sales occur on a regular basis, and you can save yourself a load of money. If you are purchasing the features separately, my suggestion is to purchase them from the same store. That way, if there is a hiccup, you won't need the issue of pointing your finger from the various stores to try and blame each other.
The smart shopper is the one who gets the quality system and doesn't pay "sticker price" for it. Be informed, know what you want, be willing to learn if you run across an intelligent salesperson who knows what he is talking about, and stick to your budget. You will be able to enjoy your investment in this superb home theater system for years to come.
Few Interesting Things About Projector Lamp Life
by Jong Hun
In order to make your projector lamp reach the maximum length in life span there are few tips that you should know as a user.
In order to correctly manipulate the projector lamp you need a piece of textile cloth or a pair of textile gloves. The lamp must never be touched with the fingers so it is always wise to manipulate the lamps components using a pair of textile gloves. The prints that remain on the glass of the lamp can cause the rising of the temperature in those areas and on the long term can significantly reduce the duration of the lamps functioning.
Another preventive measure is clearing the projectors filters. The dirty filters are blocking the air flow and cause the overheating of the lamp reducing the functioning period. In case of a replacement using the warranty certificate, the producer will test the lamp to see if the damage has occurred due to the overheating from filter clogging. If the test proves that that was the case the warranty is annulled. That is why it is very important to let the airflow around the projector as free as possible.
If you wish to introduce a new bulb in the existing lighting module of the lamp, make sure that the terminals are very tightly closed because the ceramic block can crack and that may cause ruptures that are reducing considerably the electronic isolation of the lamp.
On the other hand if the terminals are loose the risk of an electric arc to be produced is very high and this will cause the malfunction of the lamps source of power or even of the lamp itself.
Always use the remote control when stopping the projector. If you unplug the device without stopping it first the projector will invariably enter the cooling mode when the image is stopped and the fan will accelerate the cooling of the lamp in a controlled mode. The temperature of the lamp during operating mode is 1,000 C. Unplugging the lamp without letting it first passing through the off mode will cause the unequal cooling of the lamps glass which can cause the cracking of the glass and the premature malfunction of the lamp.
