Power line conditioner and surge protector
Our take on the Panamax M5300-PM by Crutchfield's Ralph Graves
The 10 rear-panel AC outlets are divided into 5 isolated banks, which helps prevent noise created by one component from affecting your other gear.
Protect your equipment and improve its performance
The Panamax M5300-PM does more than just protect your audio/video system from harmful power spikes. It also smoothes out minor current fluctuations and effectively eliminates electronic interference, giving you clear, pristine picture and sound. The M5300-PM can safeguard up to 11 components, and it includes a protected front-panel USB jack for your MP3 player, cell phone or another portable electronic device.
Clean power for high-performance audio/video gear
This power conditioner has ten AC outlets on its back panel, divided into five isolated banks to minimize cross-interference between your components. Two of the outlets accommodate high-current components, such as an amplifier and powered subwoofer. These switched outlets operate on a delay to prevent "speaker thump" when powering your system on and off. A front-panel digital voltmeter and ammeter let you closely monitor the AC power coming into your system.
Ethernet and coaxial RF protection
The M5300-PM also has two sets of protected Ethernet jacks, including one jack on the front panel, so you can surf the web without worry of power surges. A pair of protected telephone jacks prevents spikes from coming in through your phone line, while three sets of coaxial terminals shield your satellite, cable TV and antenna connections.

Features and Specs
|Total AC Outlets||11|
|Powerline Network Compatible||No|
|Connected Equipment Guarantee||$5,000,000|
|Parts Warranty||3 Years|
|Labor Warranty||3 Years|
11 AC Outlets: The Panamax M5300-PM features 1 front-panel "Always On" AC outlet, 4 rear-panel "Always On" Linear Filtered outlets divided into two separate banks, 4 rear-panel "Switched" Linear Filtered AC outlets also divided into two separate banks, 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.
- 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.
- 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 M5300-PM features a convenient AC outlet located on the front-panel for connecting your gaming system temporarily.
Level 4 Power Cleaning 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.
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 M5300-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
Power Sequencing: The M5300-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 M5300-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 M5300-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 M5300-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 M5300-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 M5300-PM features a front-panel USB type-A port for charging your MP3 player, cell phone, or other small electronic.
Digital Voltmeter: The M5300-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 Ammeter: The M5300-PM features a front-panel Digital Ammeter which shows the actual current draw (0-15A) of the connected components system, giving you a visual reference as to how your system is functioning under a variety of conditions.
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 M5300-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.
Rack-Mount Brackets: The M5300-PM comes with rack-mount brackets to mount it in a 1U rack space.
$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.

If you are facing this unit on the right side and rear you will find a terminal marked GROUND LUG. It is also just below the units circuit breaker. On my system it is gold in color and has rough edges to make it easier to grab and to turn. Unscrew it just enough to place the turntable wire either under it or round the terminal post that is now exposed to you. [ GEORGE Mar 22, 2017 ]
Perhaps I am misunderstanding the question, but here is how I view it. Often, the audio connection from turntable to pre-amp or phono amp includes a 3rd wire (in the case of an RCA type connection) to eliminate any ground loops. The power supplies of the turntable and pre-amp / phono amp may often terminate with a 3-prong style plug, containing a ground wire. The Panamax does not interfere with this arrangement, as far as I am aware. I do not believe that the audio out ground wire is to be connected to the Panamax directly. [ LOUIS Mar 21, 2017 ]
I am not really sure, I have had this thing for a while now. But I do love it, it does protect the audio equipment that I have. [ DONALD WILLIAM Mar 21, 2017 ]
Plug in the turntable and attach the ground wire to the ground lug on the Panamax. [ W. Ross Mar 21, 2017 ]
4 answers Will the USB port on this model charge a cell phone? I read a comment on a review that said; "no consistency across different models in regards to the front USB port. On my M4300-PM the USB port can charge a cell phone, on the M5300-PM although it looks like a standard USB it won't charge a phone, it's only for gaming consoles." [ MythicParty Jun 03, 2016 ]
I would be reluctant to plug a cell phone into this unit or any other unit that has not been supplied by the cell phone manufacturer. Apple recently tested several charges, that were made by other companies, that it found on the web for use with their cell phones. Some of these units did not comply with their cell phone electrical specifications. [ GEORGE Mar 22, 2017 ]
Yes, it does. The USB port is on the front face of the unit and in fact it is labeled with a little battery icon. I have used this to charge my phone. [ LOUIS Jun 04, 2016 ]
I am not sure I never have tried it. But I don't see why it wouldn't work [ DONALD WILLIAM Jun 03, 2016 ]
I have never tried a cell phone. Mine is in a rack unit and I use the usb to power a cooling fan. I have never had a problem with it, but if you are charging a phone compare the output of your charger with the output on the Panamax before trying. [ Kurtis Jun 03, 2016 ]
I bought this unit to replace a cheaper Panamax that I had that kept shutting my system down when the vacuum ran. This unit has solved that problem. Whether that is due to less bleed from different banks is hard to say, but the voltage does not drop near as much with this bigger unit. I have not experienced anything that would lead me to believe the noise filtration is any less on one bank over another. I have been very happy with my choice. [ Kurtis Feb 26, 2016 ]
It is different but not any less effective. They are isolated from the other banks so there's no noise or interference from your other components. I hope that helps! My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=5 [ Ryan Feb 25, 2016 ] Staff
bank 1 x 2 are identical, the current draw for a cable box and a TV is minimal. each bank is rated at 15amps, no where near the component need. So my answer is this-it does not matter which you use [ JOHN Jul 28, 2015 ]
Yes, you can do that. However, all banks are pre-labeled for the type of hardware that should be plugged into them. I'm sure you're aware of that already. Each bank is rated for that type of hardware and hence the reason to have them labeled for that hardware. But, if you're limited on banks to use, you can plug into that bank. [ Ed Jul 28, 2015 ]
Bsnk 3-4 and up, as I would want to keep modem and router always on (bank 1-2) [ ALEXANDER A Mar 22, 2015 ]
Have not set up yet [ JOHN Mar 21, 2015 ]
Bank 2 top outlet, it should be printed HDTV/Monitor. [ John Mar 21, 2015 ]
HDTV Monitor is where I have plugged in my lcd. [ LISA N Mar 21, 2015 ]
If I could, I wanted to also let them know how much of a difference in sound quality the Panamax makes in my home theater speakers. I have a 5.1 surround set-up with Deftech Sats and a Center. I use 1 SVS 10" ported sub. I have listened to this set-up prior to purchasing my Panamax and the difference in sound quality was night and day once I ran all of my hardware through the Panamax. The whole sound stage brightened up after I set up the Panamax. I run an Onkyo 727, Oppo BDP-93, Sony 5 Disc CD Changer and my HD cable set top through the Panamax and they all perform nicely. I've had about 4 power failures due to outages in my neighborhood and the Panamax shuts down, then sequentially powers each bank back up as advertised. I have had zero issues with the unit and it is a literally a powerhouse. Great product! [ Ed Mar 21, 2015 ]
I can't remember exactly which bank it is, but all banks are identified as to which piece of hardware plugs into which bank. That's one of the nice things about this unit, it actually identifies the bank to plug into on the back. I have a Panasonic ZT60 and it performs very well through the Panamax. So, turn the Panamax around and you'll see all banks are labeled for the type hardware that should plug into them. [ Ed Mar 21, 2015 ]
I use one of the linear filter, always on outlets. I have a plasma TV and it is normally in a standby mode where it is drawing some power. You can also turn the switched outlet on all the time. You can then use these too. [ ROBERT Mar 21, 2015 ]
