Panamax M5400-PM

Written by: mpowers1 from Apple Valley, MN on February 15, 2015

Crutchfield Customer Review (What's this?)

This box must have lowered the noise floor in my system, I'm hearing more detail and separation, the sub-woofer is sounding more integrated as well, the TV picture looks sharper. However, the voltage regulation is not worth the extra money (might as well go with the 5300). Here's a quote from Panamax tech support "The unit is not designed to keep the voltage at precisely 120v. The unit regulates the voltage +/- 7v from 120v." So unless your voltage swings +/- 7 ACV buy the 5300. Now, that said; turning off my kitchen florescent light is not tripping off my receiver, since I installed the 5400 (and it looks pretty cool, too), so I'll keep the 5400.

Pros: System protection, noticeably better sound and picture, eleven isolated outlets (2 of which are high current (and they don't starve the amps of current)), good looks.

Cons: High Price, voltage regulation may not be worth it.

The Panamax M5400 is well made as is my other Panamax equipment My old 1000 still works fine after 20 years or so , I will continue using the Panamax name for my power protetion needs in the futre

Pros: well made , heavy "for what it is" very confident it will suit anyones power managment needs

Cons: Im not crazy about the round blue lit meters , i would like to see a spectrum type looking litted meters

I will stay with Panamax

Written by: Jeff A. from Asheboro, NC on November 17, 2011

Crutchfield Customer Review (What's this?)

This is a replacement/upgrade Panamax protector. My old Panamax 1000 lasted 13 years and I figured it's time to replace to a more up to date unit than to have the old one repaired. I don't really know how many surges and voltage spikes the old Panamax saved my equipment,but I do get peace of mind knowing that I am trying to help my tv,dvd,cd player and amp equipment last as long as possible. I did choose the Panamax M5400-PM because of the voltage regulation circuity and for the longivity of the old Panamax. I will stick with the same brand that has worked for so long in the past!

Pros: I like the the voltage regulation circuit included with this product.


Excellent Product, A little pricey

Written by: Colin from Chevy Chase, MD on July 12, 2010

Crutchfield Customer Review (What's this?)

The area I live in has dirty power, with lots of brown outs and even black outs in seemingly perfect weather. I decided to use the Panamax line based on multiple reviews from various sources. I have only had the unit a short time, but I am very pleased with the performance to date.

Pros: cleaner power; my HD cable does not really look any better, but my audio has certainly improved- my receiver puts out more volume at a lower setting, while seemingly running cooler.
The isolation means that my subwoofer no longer picks up the RF from my cell phone (huge benefit).

Cons: while it does have 11 outlets, you cannot always use all of them if any of your components use a block plug. Even the smallest block will cover 2 outlets, which is annoying. I remedied this by using my old Monster Power strip for the blocked devices (Harmony remote, Harmony PS3 IR box, wireless headphones etc).
Price- this unit is expensive. I am not sure I needed to spend the extra $$ for the 5400 unit, vs the lower models, but I decided if I was going to spend the money I wanted the piece of mind of voltage regulation, which the other units do not offer.

Over all I would recommend this unit to anyone who wants to protect (and possibly improve) their multi-thousand dollar AV components.



Great Product

Written by: Donald from Irving, TX on February 13, 2010

This is a great product. The power coming into my home is very dirty and depending on the weather conditions I would have voltage sags as low as 110. The 5400 has stabilized output voltage perfectly. I also noticed a sharp increase in picture and audio quality. Everything is much cleaner.



Quality Control

Written by: Frank from Iberia,Mo. on September 8, 2009

This is good looking, BUT the Quality Control Poor for the price. It displays 126 volts in an out when it is 116 to 119 in Volts. Panamax will calibrate it but I have to pay for the shipping to panamax, For the price I think you could do better for the Money. I do not Recommend it I would not do it over. It's over priced!!!!




Written by: Michael from Atlanta on March 22, 2008

Let me start out by saying that the unit is well built, very robust, and looks cool!
That being said. there are some issues that need to be addressed.

It looks to me (after reading their training slides from their website) that M5400-PM
has an auto-transformer with three tappings providing output in the range of 100 V
to 130 V in steps of 6V. Their PRO equivalent model has steps of 2.5V (and uses a
triac), that is, more precise control on output. What happens is when the input V
(household) approaches the 124-125 range the Panamax will enter it's "buck stage"
and limit Output V by 6-10V. If your Houshold Voltage is nominally 122-125 Volts
(like mine)....this unit will introduce "voltage fluctuations" of up to 10 volts as it goes
in and out of limiting. Moreover, my unit was reading the input voltage 2-5 volts
high (compared against 3 different V meters) which was further exacerbating the
problem. I purchased a second unit that was more accurat in reading the "input
Voltage" and as a consequence did not enter limiting to the same extent.

I would think at this price point the panamax would be more accurate than it's
advertised +/- 6V....and have smaller increments in limiting it's output
V.......something to consider.....

Controls And Indicators


11 AC Outlets: The Panamax M5400-PM features 1 front-panel "Always On" AC outlet, 4 rear-panel "Always On" Linear Filtered outlets divided into two separate banks with voltage regulation, 4 rear-panel "Switched" Linear Filtered AC outlets also divided into two separate banks with voltage regulation, and 2 rear-panel "Switched/Delayed High Current" AC outlets.

  • High Current Outlets: The unit's two High Current Outlets provide power from a low impedance noise filtration circuit that does not limit the current to your equipment. Its output is noise isolated from all of the other outlets.
  • Voltage Regulated Linear Noise Filtration Outlets (Switched): The unit's four switched Linear Noise Filtration Outlets are divided into two separate banks and are controlled by the front panel Power Button or the DC Trigger input. These outlets will turn on immediately and turn off after 10 seconds. LiFT EMI/RFI noise filtration is provided by a two-stage balanced Pi filter which also provides noise isolation from the other outlet banks.
  • Voltage Regulated Linear Noise Filtration Outlets (Always On): The units four "always on" Liner Noise Filtration Outlets are divided into two separate banks and will only power off during a fault condition (under-voltage/over-voltage). Power is cleaned from these outlets by a two-stage balanced Pi filter which also provides noise isolation from the other outlet banks.
  • Gaming Outlet: The M5400-PM features a convenient AC outlet located on the front-panel for connecting your gaming system temporarily.

Level 4+ Power Leaning And Filtration: Level 4+ Power Cleaning and Filtration eliminates common symptoms of contaminated power (including loss of detail, pops, hisses, hums and visual artifacts) and allows your A/V equipment to perform up to its full capability.

Voltage Regulation: The M5400-PM features voltage regulation which improves your audio/video system's performance and prolongs your equipment's life by providing a consistent level of optimal power to all your connected equipment.

Automatic/Visual Voltage Monitoring Circuitry: Panamax's patent pending AVM circuitry continuously monitors the incoming power as displayed on the unit's digital voltmeter. In case of an under-voltage or an over-voltage, a flashing red lightning bolt will be displayed 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.

Cross-Contamination Reduction: The M5400-PM is designed to provide noise isolation between 5 isolated outlet banks including 2 high current outlets so that any noise created by an A/V component can not contaminate the power going to equipment plugged into another outlet bank.

Power Sequencing: The M5400-PM features Power Sequencing to guard against blown fuses and potential damaging speaker thump by automatically power outlets on and off in sequence. This feature minimizes in rush current issues by allowing the components plugged into the Switched Outlet Banks to power-up and stabilize before any amplifier and powered subwoofers are turned on. This sequence is reversed during shutdown. The amplifier and powered subwoofers turn off, their power supplies drain and then the equipment plugged into the Switched Outlet Banks are turned off.

Voltage Sense Trigger Input/Output: The M5400-PM voltage sense trigger input and output uses a standard 3.5mm (1/8") mini-mono plug. This feature provides an On/Off trigger for the M5400-PM using a direct current voltage signal. You can connect the DC Trigger Input to a remote trigger device that uses a DC output to trigger a start-up/shutdown sequence. The DC Trigger Output can be connected to a remote trigger device that uses a DC trigger input to pass the M5400-PM's startup/shutdown sequence to an additional device.

HD Ready Coax Jacks: The unit's bi-directional coaxial protection circuits achieve optimum signal quality from newly designed connectors that have less than 0.5 dB of attenuation from 0Hz to 2.2GHz. The unit's clamping level of 75V will meet the demands of both cable and satellite voltage while minimizing exposure to damaging spikes and surges.

Phone Jacks: The unit features an RJ-11 input and output for protecting your standard telephone or pay-per-view lines. The Phone circuit is auto-resetting.

LAN Jacks: The M5400-PM is equipped with two RJ-45 LAN inputs and one RJ-45 LAN output on it rear panel; and a bi-directional RJ-45 LAN jack on its front panel. The LAN protection circuits are designed for 1-/100 baseT Ethernet lines. The front-panel bi-directional LAN jack is an Ethernet pass-thru connection between the units front and rear panel. The front panel LAN port is also great for on-line gaming.

USB Charger: The M5400-PM features a front-panel USB type-A port for charging your MP3 player, cell phone, or other small electronic.

Digital Voltmeter: The M5400-PM features a front-panel Digital Voltmeter which monitors the voltage supplying your home theater equipment. If line voltage drops below 90VAC, or if the line voltage exceeds 142VAC, the display will turn off and the "unsafe voltage" indicator will flash indicating and unsafe voltage condition.

Digital Volts Out/Ammeter: The M5400-PM features a front-panel Digital Volts Out/Ammeter which shows the voltage the unit is proving to connected components or the actual current draw (0-15A) of your system, giving a visual reference as to how your system is functioning under a variety of conditions. The display will flash if the unit is out of regulation.

Outlet Bank Power LEDs: Each bank of outlets feature a corresponding Blue LED indicator. These LEDs indicate the status of the corresponding rear panel outlets. The LED will be lit when the outlets are turned On. They will flash during the startup and shutdown process.

Circuit Breaker: A circuit breaker is located on the back panel of the M5400-PM. The circuit breaker will trip only if the total current draw exceeds the maximum current rating (15A). This means that collectively, all outlets must draw more than 15 amps before the circuit breaker will trip.

$5,000,000 Lifetime Connected Equipment Warranty: Panamax will replace, pay to replace at fair market value, or pay to repair, up to $5,000,000 of equipment that is damaged by an AC surge while connected to a properly installed Panamax surge protector, if the surge protector shows signs of surge damage or is operating outside of design specifications. For coverage conditions and information on how to make a claim, please see the warranty sheet.
