I am going to look at several of the latest technologies that were designed to make installing home theater systems a snap. I will suggests what to look out for when making your buying decision.
As previously setting up a TV has been rather easy, the appearance of multi-channel sound has made setting up home theater systems much more complex by requiring a number of external speakers to create surround sound. Thus setting up a home theater has turn out to be quite intricate and long speaker wire runs are normally undesirable for aesthetic reasons. The signal processing is modeled after the human hearing. The signal processing has an effect that will trick the listener into assuming that the sound is coming from an alternate position.
The advantage of this technology is that only a few loudspeakers are required and no long speaker cord has to be run all through the viewing environment. The drawback though is that each human will process sound in a different way as a result of the dissimilar form of each human ear. Since the signal processing is based on a standard human ear model, virtual surround will not work equally well for each person dependant upon how much the viewer varies from the standard model.
An additional approach for avoiding long speaker cable runs is to use wireless speakers kits or wireless speakers. A wireless product contains a transmitter and one or several wireless amplifiers. A few wireless systems have wireless amplifiers that connect to two speakers. Other products come with separate wireless amplifiers for every speaker. Wireless kits frequently use the 900 MHz or 2.4 GHz frequency band. A third technology utilizes side-reflecting loudspeakers.
