Dimmer for TV signal

The Dimmers are passive elements ( not need currient to work ), they put powerdown television signal. Sometimes it is necessary to low that because the excess of the signal it is not good, at the same that a low signal, because so it is not enough. The Dimmer are manual adjustable. If we have a high signal, it is called saturation and the problem can be corrected with a dimmer placed on making television. The attenuators are adjustable. This means you can adjust how much they will attenuate the signal so as to adjust ourselves for optimum signal we need. There are different models depending on the type of connection you need.
