Without magnetic shielding, what is the minimum distance they can operate to a flat screen TV without any negative effects?

The magnetic shielding is only necessary for the old CRT televisions, the old one's with the tubes. Any modern flat screen, lcd or plasma, won't be affected so no worries there.

I don't have much room for the center channel. I have it just behind the plasma kept on a stand. I don't see any interference, so assume there is no problem due to the shielding. I might be missing little on the sound, since the speakers are behind the TV, but these sound really good for its size.

The back of the unit is half a foot from my tv and I don't notice any effect. I hope this helps.

I'm not a designer or engineer so I can't answer you regarding that. I wouldn't risk it, wouldn't want to potentially ruin my TV.

I also have a 60 inch flat screen I wouldn't say it will extend completely at 90° but it will be close everybody in the room will be able to view the television

The earlier rules of thumb for distance from a tv set were based on lower resolution screens where the issue was 'how far away do I have to be so the lines on the picture aren't visible'. Now the new issue with HDTV is 'how close should I sit for maximum realism'. The answer is in part subjective, and as such there's no exact answer, but a widely used rule of thumb is to take one tenth the screen diagonal in inches and call that the minimum distance in feet, and then increase it 50% for the maximum distance. Somewhere in that zone is optimum. So, for a 70" screen, try not to sit closer than 7' and if you are more than about 10.5' away, you're losing the maximum impact of the viewing experience.

I have heard a shielded cable works to cut down magnetic interference.I thought about that and wonder if it's not just the fact that the cable is thicker that make a difference.In effect cutting a form of interference in the form of resistance. Another cause,which would suck would be faulty internal wiring.

Was this the analog (VGA) cable or the digital cable? Nobody disagrees that shielding is not needed for analog signals, just digital. But it could be needed for digital if the interference is strong enough to interfere and cause errors. But then, it just won't work; it's not a matter of sounding better.

It's not a problem. CRT monitors are sensitive to magnets but most electronics are not.

I have not noticed any signal loss. I have 2 different televisions I am comparing though. One 6 ft away is a Sony 55" LCD, and the other with the 50 ft cable is an older Toshiba 42" plasma.

@Sherry - I can only speak to having a cell phone and an older iPod near the tiles -- and the tiles did not create any sort of problem with those electronics. Personally I believe that the magnets in this product are not strong enough to cause damage to most modern electrical devices. Plasma, LED, and LCD computers, TVs, phones etc do not suffer from the same issues that the older "big" TVs used to (they are "solid-state"). However, you might want to exercise a bit of caution by not placing the entire box of tiles on top of a computer hard drive. Hard drives can be damaged by magnetic fields.

Not sure if they are magnetically shielded but I have mine installed directly above my tv which is mounted to the wall and don't have any issues. Hope that helps

I don't think it can hurt anything, but seems to be an useless adaptation. I have to guess you are short of AC outlets in the vicinity of your application. As the specifications clearly state, the outlet is 15 amps. As long as you don't exceed that, I can't see the harm. I have called Leviton in the past about other devices and their customer service is great. I suggest you call them and ask the experts. I also suggest you just skip this purchase and just buy a regular outlet and plug in your surge strip and/or UPS. I use this product for behind my wall mounted flat screens TVs so the that I have protection and the power cable doesn't show.

Not sure on the exact distance limitation but I just walked about ten feet away and it still worked, then I went into another room and still worked with a wall in the way. So if you're thinking about using it with a media center from across the living room, you should be fine.

No, it's not. No need to pay for shielding unless you are running cabling near strong EMI sources

I solved this problem with a 50lb magnet Master Magnetics #07502 Universal Latch MagnetClose the mount to travel position, then find the best place where magnet would grab the steel mounting plate of flat screen, while magnet is attached to base arm. Makes a very strong connection and may require a good pull to dislodge from stored position, you will hear a loud click when the magnet grabs, but is very solid solution.

I currently own a Logitech Cordless Desktop EX110 that I purchased about four years ago and which also uses 27 MHz. I have measured the range at about 12 to 15 feet (transceiver to mouse and keyboard distance) over an angle of 60 degrees from one extreme to the other. I sometimes attach my laptop computer to our TV via DVI into HDMI. I sit across the room with keyboard and mouse and control the computer from there. That distance is about 9 feet, but I experimented by moving it further away which is where the 12 to 15 number comes from. Communication is best with free line-of-sight.

Yes, this speaker JBL ES20 is magnetically shielded and nothing to worry even you place it near your LG TV without affecting it's color.

My TV is near a window. Reception is very good except for the NBC station in the NY metro area. Cord is approx. 6 ft. and long enough for my needs. The directions also say it can go on an exterior wall. Did not try this.
