How To Setup Home Theater

How To Setup Home TheaterThe problems are introduced when cable TV and other externally grounded video systems are improperly connected and how to setup home theater. The sources of the problems are the differences in potential between the ground from the connected to the home theater and the power outlet on the wall or where it is plugged in, and the additional ground paths in the system.

This difference can produce 60 HZ ground currents, which become audible as noise, or it can be visible as noticed with video hum bars. Hum bars can interfere with video picture quality. How to setup home theater There are a number of factors that can cause the difference in ground potential, and of the common causes, is the grounding of the cable television coaxial cable where it enters the building. The cable grounding block should be securely grounded according to the home theater projector

National Electrical Code.

There are a number of way to eliminate audio and video hum from your home theater:

  • If possible, your entire home theater system should be connected to one outlet. This reduces the chances for introducing potential differences. This can easily be done with small systems, but can be difficult with larger systems that contain a number of different units that are located in several places throughout the house.
  • There are a few options and inexpensive device that can disable the flow of ground currents. An inexpensive option, can be the use of power strip bars that include surge suppressors. They provide power to multiple devices, but uses current from a single source.
  • Disable the ground from any display device with a 3-pin to 2-pin AC adapter.

Radio frequency ground breakers are small RF transformers, with broken ground path broken as the primary and secondary are separated. They can be easily installed in the coaxial cable line that feeds the cable box.

Getting Rid Of Humming And Noise In Your Home Theater

Video ground breakers are wideband transformers, that are also designed to break the path of the 60HZ ground current, and can be placed in line with the video cable. Another simple option is to use an AC isolation transformer, that isolates A/V equipment from the power supply, andhow to setup home theater breaks the grounding loop. They can easily be placed in series with the power cord to the home theater.

There may be special problems encountered with RF video signals. It is very important to maintain the integrity of the signal in order to preserve the quality of the pictures.
Signals should be prevented from leaking into and out of the cables.

The problems can be prevented with good quality coaxial cable, and high quality secure connectors. Routing RF signals to multiple locations such be done in parallel to reduce the chances of introducing noise.
To be able to enjoy or control what you are watching while the equipment is in another room, you can install dual cable systems that can be used for programming different TVs, as well as two way transmissions.
