The elimination of this terrible hum of your home theater speakers

!9# The elimination of this terrible hum of your home theater speakers

You have all heard that dreaded 60Hz hum through the speakers of a home theater or home audio system. I hope you have listened to a friend's house and not their own. It can drive you nuts. You may have even tried, unsuccessfully, to solve the little problem of noise. You can get even crazier. What causes that horrendous noise from the speakers?

More often than not hum from the speakers is a problem caused by grounding. There are three main reasonsThe cause of problems, the problems in an audio / video. These ground loops, improper grounding and lack of land at all. The other possible culprits that can cause noise, are a bad cable, a faulty device or electrical interference from a light dimmer or electric motor. There may be steps taken to resolve and eliminate the noise from the theater.

The first step is to understand where it came from. Disconnect the source and display device from the receiveror surround-sound processor. If the noise stops, connect it to your receiver or processor at a time, again the noise. If the hum returns, you can find where the sound system. Remember, to get that if the connection of remote devices, such as the signal travels from the theater room DVD player TV in the bedroom, the chances greatly increase the noise. It works as long as noise can in long cable runs of adjacent power lines can be induced.It 'also easy to create a ground loop, because the device is connected to two spaced points on different circuits.

If the noise is caused by a cable box, the noise is probably caused by the earth cable TV. To test this theory, remove the power cable input on the back of your cable box or TV while they are still connected to the rest of the system. If the sound using the TV cable is removed, the problem is the ground cable. Theircan electrically decouple the cable TV feed from your system with an innovative transformer. These come from many sources. Indicated that require a lot of newer, digital cable TV systems, each device in the signal chain to pass a full 1,000 MHz of Some old transformers will not pass through. Make sure you buy the device specifications of control, the cable digital TV signal.

If the noise of the projector, a television orMonitoring is most likely caused by the fact that the video display device is connected to an outlet other than A / V equipment. It could also be a different circuit. These circuits are two different ground potentials. This means that the resistance to earth of each different circuit. A difference in the resistance to earth from one point to another land, the earthly cycle feared. If you have a ground loop, a current flow between the two components to obtain. When current passes throughcomponents of the internal terrain of the audio signal, you get a buzz.

You can use an isolation transformer, similar to the type of soil problems for the cable used to eliminate the electrical connection between components. These transformers are inserted in accordance with the audio signal connection between the two components. If there is no audio connection between components, the problem may be present through the video. In this case, a video isolation transformermust be used to eliminate ground loops.

Sometimes conditioners will be problems of noise from different devices to stop isolated branches. This is done by using isolation transformers. Sometimes this is ineffective, however, due to differences in the internal structure of the various power conditioning equipment. Some safety rules, such as specifying UL 1950, which is an isolation transformer is only allowed to isolate the hot and neutral wires, ground wiremust pass only to be. If this is the case, the problem persists ground loop, because many communication circuits are connected to the conductor and the neutral. In this case, the isolation transformer or a power supply or UPS with an isolation transformer will have absolutely no effect on the problem of grounding influence.

Noise can be generated externally by a refrigeration compressor or dimmer, for example, and that the main poweraudio-video equipment. In this case, a power conditioner, high-quality effective in reducing or eliminating the noise problem. You may also notice that one of the signal cables in the system is defective. This can also cause noise problems. Check if replacing the cable with one that is known to be good.

You can solve problems more noise in your home theater and multiroom audio / video from the systematic, step-by-step approach. Work your way up toThe signal chain so that each device as you go. If you do not change the speakers with the exception of the speaker cables, and still have the buzz, the noise problem in the wiring from power lines adjacent speakers is induced. Other than this case, most of the problems caused by problems of land, which you can find and fix, if you do a step at a time.
