Panamax - M5400-PM 11 Outlet Home Theater Power Conditioner

Excelente producto llego bien protegido

Excelente para proteger aparelhos eletrônicos sensíveis e, como ele próprio não é barato, é bom proteger ele também com um dps :D.

I'll start with the surprising good news about this unit - after plugging my HT system components into this device, the picture got brighter on the high-end Sony TV. This was an unexpected shock to the two people who witnessed it because we both spontaneously noticed the picture quality change at the same time, and both of us are very suspicious of snake oil related claims. The power outlet I'm forced to use for our system is on the far end of a GFCI device, so that might be related (for one thing, I can't run ethernet over powerline with this outlet).We run the unit as always-on and control power to the components individually, so I can't speak to the timed shutdown and startup features. We don't have tube equipment or anything that needs to warm up. Our OLED TV prefers to have power at all times even when "off" so it can do panel self-maintenance and download firmware updates, and it controls the soundbar and subwoofer and rear speakers so there's no need for sequencing there. The streaming boxes (Roku, Apple) take little power, and the DVD player is turned on only when being used. So the Panamax is always on.I like the front meters that show both volts and amps, but the quality of the blue LEDs that light the meters is questionable - they are a bit cheap looking and the brightness adjustments are not sufficiently adjustable.This is in contrast to the rest of the unit which feels very solid and well built.The utility value of including protection for phone (landlines) and ethernet is questionable - if you can't provide protection at the point of entry into your house then they are mostly useless. Most HT systems are not located at the same place in the house as the point of entry for the phone lines and primary internet connection. The days of these kinds of things being useful are waning - I'd rather have another pair of outlets. Ditto for the USB port on the front - I've already got plenty of ways to charge my phone. When contemplating this box, I'm most of all interested solely in 120VAC power conditioning.There has been no transformer buzzing or any other kind of noise from the unit I got - it has been utterly silent at all times.We've had no power problems so far that would trip the over- or under-voltage reactions so I can't address how this unit behaves when something like that happens. And I hope I never have to. But the cost of this unit was about 10% of the cost of the electronic components it is protecting, so it feels like worthwhile insurance.*Update 03/05/2024* This product now costs $750, which is $300 more than when I bought it less than 3 months ago.

Excellent productExcellent sellerKeep it up

I was concerned about a couple of reports of a "Loud Buzzing" coming from the unit but mine had no loud buzzing. Having an electrical generator featured on the 5400 vs the 5300 I wanted that extra protection during surges. I put my ear against the unit itself and heard a minimal hum (Normal) and if I turned off all items (tv, frig, furnace, etc) I could barely hear a low hum at 1' but nothing beyond that and certainly nothing noticeable. Plugged everything in and still quiet. I sit 8' feet away and nothing at all so I'm not sure what people are referring to. This replaced my 22-year-old Panamax 5500-ex (Their flagship unit back in 2002) which finally gave out saving all of my very expensive components 65" Sony Bravia tv, Sony sacd player, Panasonic UHDTV & Denon S950H receiver. Served me very well so sticking with their flagship unit. Peace of mind and 4 dimmable options down to a few tiny blue led lights just the perfect ambience no distraction. Oh... great price too for what it does and features you get. No brainer.
