Wireless TV speakers are almost a necessity for a household which boasts of a modern LCD, LED or a plasma TV, because most of the flat panel TV’s built in speakers but aren’t really that good when it comes to getting the full effect of surround sound entertainment. The inbuilt speakers must usually be limited in output power (less than 15 Watt) due to problems of heat dissipation when residing within the TV as well as mutual interferences with the screen. It is only by detaching the speakers from the screen, that it is possible to offer truly high definition audio quality. Surround sound is considered the best for full cinematic experience from the comfort of one’s own home. Moreover, the wireless TV speaker solutions eliminate the need to route the speaker cable through ducts in the walls and ceilings and neither will there be cables lying scattered all over the floor.
Your home theater audio system can be connected to your TV without speaker wires including the rear speakers and full surround sound. It can also include mp3 players and and additional indoor outdoor wireless stereo speakers. In fact the sound quality of your home theater system can be sent any where in your home through wireless stereo speakers.
The technology used is similar to those used for wireless speaker systems wherein, the main speaker unit combines the loudspeaker with a radio frequency (RF) receiver and a radio frequency transmitter unit. The transmitter connects to the audio output slot from the television. An RCA plug or cable as is it popularly known is used to connect with the televisions line level output. In most cases, the TV’s speaker will act as the center channel in a multi-speaker setup.
Usual concerns about signal interferences cannot be eliminated altogether since the wireless transmitter unit emits signals in the 900MHz or 2.4GHz frequencies, which overlaps with the range of frequency of other wireless domestic gadgets such as mobile phones and microwave ovens operating on the same band widths. One should also not forget that the external wireless amplification circuits and the radio frequency receiver housed within the wireless speakers need to be connected to an AC power source in order to operate and produce sound which is played over the speaker cones.
Popular solutions available in the market includes Audio Unlimited 900Mhz Wireless Speakers from Cables Unlimited, Acoustic Research AW877 900Mhz Wireless Stereo Speaker System, Grace Digital SCN300W Schooners, TV Ears 10380 Wireless Speaker System, Boston Acoustics TVee Powered Soundbar Speaker System with Wireless Subwoofer etc, although this is not a surround sound solution. Technological advancements has lead to the development of the IrGate™ platform, which has the traits of RF technology within an omni directional operation and claims to have minimum susceptibility to various RF interferences.
Having an external set of wireless TV speakers would therefore add to the viewing pleasure and offer a sound experience which will be a close replication of the real life environment matching the video being played on the TV screen, whether it is a movie or a sporting event.
