I know that unshielded speakers do. But does a regular receiver generate a magnetic field? I am building a kind of bookcase that will include 2 receivers one above each other, about 3 inches apart -- 2 feet away from a DLP TV set. Should I worry about distortions in the TV picture? Thank you.

If the receiver has a metal case that is grounded (i.e. all of them do), this acts as a Faraday cage which blocks EM radiation...

If you have a DLP TV, no need to worry about magnetic fields- it's all done with mirrors.

Andrikos is correct, but there is a difference between EM radiation and a static magnetic field. The latter is what causes problems with TVs. The receiver certainly generates static magnetic fields, as it has a ferromagnetic transformer on its power supply. However, it is nowhere near as bad as with a speaker, and probably will not cause a problem.


Besides for a DLP, there is no problem.
