Planning To Go Hi-Tech With HDTV?
Posted By Jordan Lee on April 22, 2010
High Definition TV or HDTV has changed the life of many when it comes to watching a movie or a show. The video we get from HDTV is a whole lot better than the analog TV that we’ve gotten used to. Nevertheless, to complete the whole set up, you also need to have quality audio. Your TV may have the best speakers but they are not comparable to an appropriate surround audio unit.
Both widely available are the main principal choices, 5.1 and 7.1. These numbers pertain to the number of provided channels. Six speakers can be supported by a 5.1 system. Designed to duplicate low frequencies like explosions and thunder, the ‘.1′ refers to the subwoofer. The number 5 refers to the other speakers. Divided as left and right, these speakers or satellites are positioned as follows: in front of the listener, to the rear on each side and central front place. Having the same set-up as that of the 5.1, 7.7 systems use additional two speakers positioned at the back of the listener. A not so popular version is the 6.1, which add just one extra channel.
Providing a more realistic sound experience is the 7.1 version as it got more substance and immersive qualities. The 7.1 is best suited for big rooms. Exceedingly ideal for most applications is the 5.1 version.
If you decide to buy a surround sound system, you may choose to purchase an A/V receiver and speakers separately, or opt for one of the many packages on the market which include everything you need. Both options have their advantages, for example it’s usually easier to set up an all-in-one package; but buying separately allows you to choose the best individual components for your particular requirements. The receiver is the heart of a surround sound system, supplying the amplification and providing inputs and outputs. Don’t be too concerned with buying a particularly high power receiver. Vendors often quote impressive-sounding wattages, which many people translate into meaning high volumes; this is not necessarily the case. If you’re concerned about all the cabling involved, it may be a good idea to consider a wireless system. While these are not a true cable-free option, they do eliminate the need for cabling to the rear (surround) speakers.
Once you have purchased your system, take time to plan the location of the TV and other components. Proper speaker positioning can have a dramatic effect on the overall audio experience.
Problems of space and price? You will be happy to know that you can aim for surround audio via the ‘virtual’ surround sound. The new TV models have this facility where surround experience is imitated although there are only two speakers with a system like the SRS Trusound.
