A:AnswerIf it is the one on the right that looks like an outlet it means that there is a fault in your line. The one on the left that looks like a caution sign means that their is an unsafe voltage and it disconnected power to protect your equipment.
A:AnswerIf you are only plugging in a tv and nothing else and your outlet is really close to the back of the tv I would recommend the panamax mfp-300 for being designed to hide behind your tv if its wall mounted but If you have more than 2 items I would go for the mr 4000 or the mr 4300
A:AnswerNo if you are referring to their larger units they have more advanced protection than the mr 4000 such as better power filtering. If you have some what high end audio components such as power amps or subwoofers than the mr 5400pm would be a nicer option with power banks allowing you to have more power when you music calls for it without harming your gear. If you have some bookshelf speakers that are not crazy expensive like I do I went for the mr 4000 because its smaller and more compact and still gave me my AVM and power filtration as well. If you have less than 8 you can still use all of their lineup regardless if you have less devices plugged into them.
