Description
Make sure you're getting the most out of your home theater equipment with the MAX 5400-PM from Panamax. Voltage Regulation Improve system performance and prolong equipment life by providing a consistent level of optimal power to your equipment. Improves Picture and Sound Quality Level 4+ power cleaning and filtration eliminates common symptoms of contaminated power (including loss of detail, pops, hisses, hums and visual artifacts) and allows you`re a/V equipment to perform up to its full capability. Monitors Incoming Line Voltage and Provides a Visual Indication of Power Level Panamax's patent pending AVM circuitry continuosly monitors the incoming power as displayed on the digital voltmeter. In case of an undervoltage or an overvoltage, a flashing lightning bolt will be displayed in red in the voltmeter, and power to the connected equipment is automatically turned off if either of these conditions is detected. When voltage returns to a safe level, power to the equipment is automatically reconnected. Reduces Cross-Contamination Between Components The M5400-PM is designed to provide noise isolation between 5 isolated outlet banks (including 1 bank with 2 high current outlets) so that any noise created by an A/V component cannot contaminate the power going to equipment plugged into another outlet bank.

Works great, but contains features that could now be considered obsolete and unwanted
Size: M5400-PM
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.

Protection Confirmed!
Size: M5400-PM
1/2/13 Update: Protection confirmed again! And, again, no simple surge protector would have done this. We experienced a very strange power outage. It appeared to begin with a surge followed by voltage dropping from 120V to 60V (where it remained for about an hour). The Panamax immediately cut the power to everything plugged into it and did not pass the 60V of power through to any of the devices during the outage. Low voltage (below 108V) can also harm electronics! For the rest of my devices (refrigerator, dishwasher, etc.) I had to manually trip the breakers so as to avoid damage to those devices. In the end (other than one CFL bulb), everything seemed to work normally (whether plugged into the Panamax or not). But, this sort of damage is cumulative and not always immediately evident. So, I'd say it is safe to assume that -- at a minimum -- the devices plugged into the Panamax had their life expectancy extended. 7/26/10 Update: The voltage anomaly occurred! This weekend, my electric company -- with no apparent external factors involved -- pushed 125 to 127 volts into my home for the entire weekend (122 to 124 is normal for them). At 127 volts, the Buck stage kicked in and reduced the voltage to 117. The Buck stage continued to supply reduced voltage until the input voltage dropped to 123. The CBEMA curve suggests that computer equipment (and, presumably, other electronic equipment) is designed to function properly at plus or minus 10% of 120 volts. However, functioning properly is one thing and sustaining damage over time is another. This Panamax product is designed to keep the voltage within plus or minus 5% of 120 volts. This weekend, the product performed as advertised. In doing so, it might have prolonged the life of my home theater equipment. No simple surge protector could do that. Original review follows: Until a voltage anomaly occurs, it is hard to know how this unit performs. But, I have no reason to doubt the listed specifications. Based upon those specifications, this unit should provide far, FAR better protection than a simple surge protector. And, it appears to be a far better value than even the entry level voltage regulator from Monster, inc (the AVS 2000). The online manual for the AVS 2000 -- unlike this Panamax -- offers very few specifics on voltage regulation. Here in the wild, wild west, various critters tend to find their way into our electrical grid, thereby shorting things out in sometimes spectacular ways and creating all sorts of havoc, voltage anomalies and blackouts. The damage suffered by my previous A/V system -- then protected by a high quality surge protector -- may well have been caused by these errant critters. My hope and expectation is that this unit will substantially prolong the useful life of my new A/V system. Subjectively speaking, this unit does seem to have improved the picture and sound quality. But, I did not do any side-by-side testing.

Replaced my 22year old 5500-ex. Works exactly as expected. Beautiful picture & surge protection
Size: M5400-PM
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.

My older version of this product gave up the ghost after 25 years of faithful service. I know it saved my stereo system from electrical spikes many times and I wanted to replace it with a better one. I love the blue glow it gives off in a darkened room

Size: M5400-PM
Yea I like this. I don't buy some of the snake oil about some of the products out there and I'm sure at some point given XX surge or lightening strike...electronics will be damaged. I take reasonable precautions given my stero gear. This device has a number of good features and appears to be well made. I have no ability to comment on the actual internal components used in the device. easy to use and easy to setup and follow the instructions. I believe some of the products will have the brand name "Nice" on them vs. panamax.

Panamax/NICE M5400 still a fantastic power unit!
Size: M5400-PM
This is my third one of these. Showed up under NICE badge. No, all is good there. New owners, badges. One went "missing" on move to our new house. I have one for my stereo equipment, and one for my A/V home theater since they are on different floors of my house. I live an area that has over/under voltage situations all the time due to power outages, generator start ups etc.. Never had a problem with the unit, and it does a fantastic job on my high-end home theater and stereo equipment. I have learned from experience that you need to hook up all the connections that your A/V has through this unit for total protection. Stray items that aren't protected may get zapped, and then zap other units along that same power path (very simplified explanation).

Appears to do what they claim. BUT, there IS an audible hum when it is powered on. ANNOYING.
Size: M5400-PM
So far it looks like it does what they claim. I bought it even after reading a lot of the reviews and making a judgement call on the ones that talked about the hum you hear when it is plugged into the wall. I was hoping it was just a few duds or people who just complain over small things. HOWEVER, it definitely has an audible hum. It is very annoying. I am living with it by leaving it shut in the media console. But if this was not behind closed doors, I would be returning it. It wouldnt be so bad if it was in an environment that had a lot of ambient noise. But considering most higher end media equipment is in quiet rooms where sometimes quiet movies are played etc..... This is borderline unacceptable. Edit 2025-01……. This thing is the most annoying piece of junk I have ever bought. I was building out a media room/game room with some very high end equipment. 83inch LG C3 oled tv, ps5, AppleTv, Nakamichi Dragon soundbar setup with 2 8inch subs and one of the new 12 inch subs, Restoration Hardware media console, etc etc. I wanted the best protection for the devices and something that complemented the very very expensive media console. I am not able to game with the ps5 shut up in the media console with doors shut so I leave one door open for air flow while playing. The noise from this Panamax is unbearable. I have a lower end Panamax that doesn’t have the voltage regulation and it makes no noise whatsoever. This thing makes a horrible noise that has become to become my nails on a chalkboard unfortunately. It is too late to return it but I guess I will work with Panamax to see if there is anything that can be done. I am VERY disappointed in this unit. I am considering taking it out and throwing it away. I hate to waste the money but it is JUST THAT BAD.
