Manufacturers have recently released new products and technologies. These products were designed to help simplify the installation of home theater products. It then utilizes signal processing to those components and inserts special cues and phase delays. The disadvantage though is that each person will process sound differently because of the different form of each human ear. An alternative approach for simplifying home theater setups and eliminating long speaker cable runs is to employ wireless surround sound products or wireless speakers. A wireless solution will generally incorporate a transmitter module that connects to the TV or source and in addition wireless amplifiers that will be connected to the remote speakers. Ideally it should come with a volume control to adjust it to the audio source.
Whilst a number of wireless sound kits shown at amphony.com/products/wireless-surround-sound.htm come with a wireless amplifier that connects to two speakers, other products offer separate wireless amplifiers for each loudspeaker. To make certain that all speakers are in sync in a multi-channel application, ensure that you pick a wireless system that has an audio latency of a few milliseconds at most. This effect would deteriorate the surround effect. Most wireless gadgets work in the 900 MHz and 2.4 GHz frequency bands. Some products utilize the less crowded 5.8 GHz frequency band and therefore have less competition from other wireless products. An alternative method, which is often referred to as sound bars utilizes side-reflecting loudspeakers. On the other hand, realistic scenarios often will differ from this ideal and diminish the effect of this solution.
