Protect your equipment and improve its performance

M4300-PM back panel

Bullet-proof protection for your entire audio/video system.

A home theater system requires clean, consistent AC power to operate at its best. Panamax's M4300-PM protects up to nine components from harmful power spikes and surges, as well as the minor voltage fluctuations that can compromise your system's performance over time. It also filters the incoming AC power, removing line noise to maximize your system's picture and sound quality. Easy to hook up and easy to use, the M4300-MP is our best-selling line conditioner.

Automatic protection for your peace of mind

Panamax's patent pending AVM™ circuitry continuously monitors the incoming power. If either undervoltage or overvoltage is detected, power to the connected equipment is automatically turned off. When the line voltage returns to a safe level, power is automatically reconnected.

The eight AC outlets on the back panel are divided into two isolated banks. One bank handles high-current components, such as your receiver and subwoofer, while the other bank handles your other audio/video gear. Isolating the outlet banks from one another prevents noise contamination between components. A front-panel convenience outlet lets you quickly plug in a video game system or camcorder.

Two sets of coaxial inputs and outputs protect your satellite, cable or TV antenna connections. A pair of protected phone jacks prevents spikes from sneaking in through your phone line, and a pair of Ethernet jacks protects your network connection. This versatile unit also features a protected front-panel USB charger for your MP3 player, cell phone or other portable electronic device.


Dual front-panel convenience lights shine downward to illuminate your other components.

Conveniences that enhance day-to-day use

A digital voltmeter with adjustable brightness lets you monitor the power coming into your system. The M4300-PM also features two hooded convenience lights that shine downward to illuminate the front panels of your stacked components. You can change the intensity of these lights, or turn them off, as you prefer.

Product Highlights:

  • 9 AC outlets with two isolated banks:
    • one isolated bank of four switched outlets
    • one isolated bank of four switched high-current outlets
    • one front-panel convenience outlet
  • surge and over- and under-voltage protection
  • AVM™ circuitry monitors incoming power and automatically cuts power to connected equipment if undervoltage or overvoltage is detected
  • EMI/RFI noise filtering for clearer sound and picture
  • two sets of coaxial RF connections for cable/satellite/TV antenna
  • RJ-45 LAN line input and output
  • RJ-11 phone line input and output
  • front-panel USB charger for use with MP3 players, cell phones, and other portable devices
  • two front-panel convenience lights with adjustable brightness
  • front-panel digital voltmeter
  • 1650-joule surge protection
  • maximum current rating: 15 amps
  • 17"W x 2-1/8"H x 9-3/8"D
  • warranty: 3 years
  • Our 60-day money-back guarantee
  • $5 million connected-equipment warranty (covers equipment that is damaged by an AC surge while connected to a properly installed Panamax surge protector if protector shows signs of surge damage or is operating outside of design specifications)

It Works

Written By MichaelM, San Francisco, CA on Thursday, April 03, 2014

Crutchfield Customer Review (What's this?)

My Meridian home theatre speaker system is sensitive to power fluctuations, and didn't work with common power strips. With the clean power delivery of the Panamax M4300-PM the system runs flawlessly.

Pros: Performing, quiet, attractive

Cons: Not sure why the power lights need to be so bright. They almost light up a room at night

Everything they say it is!

I was having 60 cycle hum problems with another product and purchased the Panamax 4300 because their claim of eliminating noise. It did the trick! It was everything they in terms of performance. Further, it is attractive and very easy to install. I recommend Panamax to all.

Pros: Quiet, attactive, compact with great display

Cons: None

This equipment has been a lifesaver. We had a bad storm the other night, high winds, rain, etc. Well the power went out, and I of course started to worry about my electronic equipt.. And then I remembered I had the Panamax for surge and brown out protection. Kept eye on everthing as this was first storm after purchase. Worked like a charm.

Great Items at a great price.

Written By Fable, Connecticut on Wednesday, November 06, 2013

Crutchfield Customer Review (What's this?)

Overall this item has been great to me over the past few months. I did a lot of research trying to find a unit that wouldn't break the bank as some of the line conditioners are 500+ dollars. With the current discounts (which have been in place for some time), this is an amazing price for this device. I just bought my second unit to cover my incomming PS4 and all of it's related tech (chargers, wireless headsets, etc). Just keep my con in mind. If you have a lot of larger you may need to get creative or use small extension chords.

Pros: The unit has an appealing front face and the display is handy to show total load on the device. The ability to run Cable through the conditioner is a big plus in my book. Finally as noted in my Review - the price is fantastic for this level of hardware.

Cons: In an attempt to cram as many plugs into this compact unit as possible, larger plugs are not easily used. I was able to get around this by using the USB and single plug on the front of the unit.

Crutchfield Customer Review (What's this?)

I immediately noticed a substantial difference in the way my Home Theater sounded! Everything in multichannel, SACD, BDA, DVD AUDIO, etc.....all sounded much clearer, and more open! Then I clicked on the TV. I have HD CABLE, and it was now so clear and vibrant. I thought it looked good before, and I had a pretty good surge protector before, but this beat it hands down! Great product, and super fast shipping!!!

Pros: Much Clearer audio and video Compact Simple installation

Cons: Can't hookup larger power cords, too close together, but there are ways around it!! ( 8" extensions that come in a 3 pack!)

Written By BillC, Sarasota, FL on Monday, September 16, 2013

Crutchfield Customer Review (What's this?)

I had been looking for a reliable surge protector for a Plasma TV after I had lost one to a power surge. After extensive research I decided to go with the Panamax M4300-PM. I was not expecting that it would improve the picture quality and sound but it fact in my opinion it did. I like the volt display, which in my case does fluctuate from 123 - 128volts. Also the two LED light that point down are very helpful for loading DVDs in low light.

Pros: Great brand and two inputs for coax which is great if you have Directv!

Cons: Price, but you get what you pay for and Crutchfield by far had the best deal that I could find.

Panamax M4300-PM

Written By, Lookout, WV on Thursday, August 29, 2013

Crutchfield Customer Review (What's this?)

I ordered this as front line protection for my son's home theater. He and my daughter in law had damage to some components previous to the purchase and have experienced none since the installation. I would guess the 4300 is displaying an average plus or minus 2% fluctuation in voltage from the utility company was the root most likely the cause of previous damage, No isuses with components to date and the picture seems to be clearer and with good sound quality since the hookup.

Pros: Does what it is intended to do.

Cons: Better price point.

Power strip - Panamax M4300

Written By Power strip, Green Brook, NJ on Thursday, August 22, 2013

Crutchfield Customer Review (What's this?)

Great product. I like the look of the unit and the two lights that can be turned on and off as needed. The lighting feature is a great idea and helps to view all the controls of the system I have just under this unit. Has a lot of outlets on the back of the unit and one in the front.

Pros: Two user controlled lights and plenty of power outlets

Cons: None

Pros: everything

Cons: nothing

Nice Life Ins for your gear...

Written By Sptipps, Irving, Texas on Sunday, August 18, 2013

Crutchfield Customer Review (What's this?)

This a nice life insurance policy for your gear. We spend a lot of hard earned dollars for our electronics and seldom do we think to protect it against power fluxuations. This item will help you do just that and it has so many plugs (holes, George) to put your gear in, you'll be impressed. It even is a stylish addition to your media center. Well worth the money and should give you a little piece of mind.

Pros: Design, Number of outlets and flexiablity.

Cons: None at this time. Let's what for a good old fashion Texas Thunderstorm and see what she does...

Panamax M4300-PM

Written By JD, Texas on Tuesday, July 30, 2013

Crutchfield Customer Review (What's this?)

After reviewing different brands and model offerings, I purchased this unit based on the level of protection and options available. I hooked up the Panamax and immediately noticed an improvement in the quality of video. Connecting the Panamax was straightforward and the display panel provides information at a glance, and the slim design is perfect for limited space.. The USB connection on the front panel provides convenient charging options for a variety of devices, and the accent lights are a nice touch.

Pros: Intuitive hookup, easy to use, easy to place within existing system. Slim design and great options

Good Protection

Pros: Good protection. Improved video.

Cons: Bright display can be distracting.

Crutchfield Customer Review (What's this?)

I'm very pleased with my purchase! It improved all my electronics, TV looks better than before, no hum in my subs, I like accent lights to illuminate and show off my stereo. The only flaw is with the Blue display, it is too bright, but I just placed a piece of tape over it.

Pros: Price, stylish, blends with my other electronics.

Cons: Bright blue display.

Great product. Not too pricey. I ordered this to serve as protective barrier for my high end AV system which I have set up in my country vac home. I will not hesitate to recommend this model to anyone. The front panel lights also looks quite inviting. I am considering getting another one for my desktop as well.

Pros: Simple, practical and reasonably priced

Cons: It's not clear on the owners manual whether I can sit this on top or under a blu ray player

It told me the amount of volt going to my equipment.

Didn't think I needed this but was wrong

Written By Majog, NY on Tuesday, July 09, 2013

Crutchfield Customer Review (What's this?)

When I bought this I didn't really think I needed it. I live in the country and have not had many power issues but thought with the new system I bought it would provide a measure of power related safety and save me money in the long run. When I got it in I was amazed. It can drive most anything from cable tv, to wall power, etc., and has enough outlets for lots of equipement. The cute nightlight feature is nice but not really needed. Most useful was the power display that showed my wall power output in volts. I had no idea my wall power was as dirty and fluctuated as much as it did going from 109 volts up to 128. Good thing I got this. Would love the display to show the frequency output too though. Only downside is that if you have equipment on both sides of a room you either need more than 1 or have cables running around the room.

Pros: Lots or features; lots of power outputs, easy to set up; power input disply

Cons: need more than one in a big room

Excellent product. Easy hook-up. Here in the lightning capital of the western hemisphere good surge protection is highly recommended. After all, with a power grid that dates to pre-WWII, and many summer storms I want my electronics protected. This product is just the ticket.

Pros: Easy hook-up. Slim profile. Sturdy.

Image quality: Seemed to help enhanced/brighten colors and tones. Power stability: No more "pop" and outage from my receiver. Volt reading: Great. I've watched it jump from 20 to 24 and down to 16. Nice to know what's coming in. Equipment Powered: Pioneer 61-in. Plasma, Denon receiver, Infinity surround and sub, Xbox, cable box

Pros: Cleaner tv image. Simple-simple-simple to use. Plenty of outlets. Overall a fantastic product.

Crutchfield Customer Review (What's this?)

Excellent line conditioner/surge suppressor for a smaller dedicated HT system. Build quality is excellent, heavy duty power cord, isolated outlet banks and accessory lights to aid in seeing in a darkened HT room.

Pros: Isolated outlet banks, slim profile, voltage meter, accessory lights, just the right amount of outlets.

Cons: Power cord not detachable so upgrade is not possible.

Best bargain in power conditioners

Could not be happier with purchase. For the price, nothing comes close. High quality, on and off switch for components, AND protects against low voltages as well as surges. Dimming led's, USB charger in front, all in a very attractive, quality look. Would highly recommend for protecting your gear.

Pros: Price, quality, and myriad of functions.

Cons: None

Written By Roy, St. Paul, VA on Sunday, June 09, 2013

Crutchfield Customer Review (What's this?)

Works as advertised. Have you ever noticed lines on your television (or static in your music) when somone is using a power tool nearby? That is noise generated on the power wire (to an extreme). Your incoming power always has a small amount of this coming in, and this unit will help filter it out! Just a great product if you want great power protection plus improved performance from connected gear!

Pros: Value, convenience, and looks appealing.

Cons: NONE

Crutchfield Customer Review (What's this?)

so far, this power , cnter is pretty darn good! Able to connect everything. my only minor issue is the blue lcd lighting is way too bright! no way to turn thatoff so we have it covered with black paperand tape. the tape does not stick well to the textured finnishhe of the unit! no abig deal but this is in our bedroom and weare not lookking for all the lighting! we are able to turn off the soft glowing lights meant to illuminate equipment undeer thee panamax.

itt wasa choice betweeen thisuit and a newer model locally. that unit was $100 more for essentially one neew feeature... it had gigabit ethernet passs-through. i am not running my nnewrok through the unit and did not think the extra $100 was worthwhile! ! i spoke to both panamax and Crutchfield before the purchase and am staisfieed with my decision! the joule rating and clamping power are very simiar on the 2 units!

unless you really need true line power conditioning, i think this a no-brainner type of purchase! don't even bother with cheap power strips! pamax also makes a similar product that is more like a power strip that you just put behind your furniture, on the floor. you give up an otlet on the back and thee convenience outlet on the front...

Works well for me

Excellent especially for the price. Replaced a standard surge protector strip with this. It not only made my picture a little better but increased the output of my receiver by 5db. Highly recommended. Hopefully I never have to find out how it protects against a large surge, but definitely worth the money for the piece of mind. As an electrician, I like the ability to see what voltage it is putting out.

Pros: Lights on front, plenty of outlets

Written By BURG, Lumberton,NJ on Wednesday, December 26, 2012

Crutchfield Customer Review (What's this?)

This is the most important piece of equipment in your Home Theater system! The US power grid is not 100% stable. Brown-outs occur thousands of times a day throughout the country. The electricity coming into your residence is contaminated with nasties like EMI/RFI etc. A lightning strike or power surge a mile,5 miles even 10 miles away has the potential to destroy your A/V system.Can you replace your equipment for $175? Probably not. Six years ago a storm 7 miles from my residence sent a power surge into the PANAMAX line conditioner/surge suppressor in my A/V system. Not one piece of the connected equipment was damaged,although the PANAMAX was fried! I rest my case.

Pros: Superior audio and video quality.Power cords are neatly placed.Adjustable lighting makes it easy to see the controls on your A/V Receiver. Great price!

Cons: NONE

My receiver seems to have more power and my subwoofer hits a whole lot harder now. If you question your power even just a little bit, consider what you paid for your TV and the small cost of this unit - and get one. Might be one of the best purchases I have ever made.

Pros: Is everything it is advertised to be.

Cons: The only thing I wish it could do was the ability to dim the main display light, that's it!

Crutchfield Customer Review (What's this?)

Great sale price at $175.00

Pros: Compact size, front USB port and grounded front power outlet.

Cons: Does not have a dimmer for the voltage readout and no switch to turn completely off. Also has ugly amber front lighting that can be dimmed or turned off.

Panamax M4300-PM

This unit looks so good on my TV stand along with my gears. I pluged the LCD TV and Denon receiver in it. The resolution of the TV looks a little more sharper. I bought electronic gears from Crutchfield since 1984, and I knew Crutchfield sell high quality products. I am happy with my purchase for this item.

Pros: It has an USB charger and a gaming outlet on the front panel.

Crutchfield Customer Review (What's this?)

A Crutchfield advisor recommended purchasing this powerline conditioner for my home theater. I was on the fence about it given the price, but I had gotten good holiday deals for the other big components of my system, so I figured I could still fit this into my budget.

Overall, I definitely recommend the M4300-PM to anyone setting up a home theater system. It's built well and provides organization to all your power cords. The power outlet on the front of the unit is very practical, and I intend to use it often when I need juice for my laptop while it's streaming to the TV. The orange front lights are a cool-looking feature that actually comes in handy as well, especially if you have a dark room and need light to see the controls on your A/V receiver.

Pros: Provides clean power, keeps your system organized, and comes with convenient functions, e.g. front outlet and front lighting (which can be toggled to different brightness settings).

Cons: If you're just looking for a basic surge protector for your system, there is sure to be cheaper out there.

Great Product

Great product that I got for a great price! Feels like I stole it from Crutchfield! Noticed a better picture and sound...not alot, but noticable to me. The hum in my powered subs is virtually gone (have a loose RCA that is the culprit) but the noise was cut down significantly. The amber and blue LEDs are a cool touch and I like how they can be dimmed or turned off.

Pros: Does what they claim it can do. Sort of a rarity now a days.

Cons: None.

Panamax M4300-PM

Written By Tom, Ohio on Thursday, December 06, 2012

Crutchfield Customer Review (What's this?)

Nice unit, sturdy construction. Runs a little warm in my system but is a very nice additional. The downlights are a great touch and are useable in my system, however it would be nice so that they could be rotated to aim upwards or at angles. Would be great too if you could dim the main display but hey at the marked down price, it's good.

Pros: USB port on the front, good display, solid construction including long, beefy power cord.

Cons: None really.

Crutchfield Customer Review (What's this?)

If you have a nice system but are on the fence because of the "you don't need a power conditioner" rhetoric that exists out there in some corners of the A/V world, let me suggest to you that it is time to get off. Let's be honest, yes, you don't need it. But you don't "need" a nice system to begin with, do you? Or a hot wife/girlfriend? Or any number of things. No, since hooking it up, lightning hasn't struck my house or anything, putting my Panamax to its most extreme test. I have, however, noticed better picture and sound. It's subtle, but if I notice it...that's what counts. The main display shows you the deviation between what your utility company is pumping out of your outlet and into your swanky audio components and HDTV. Trust me, it ain't exactly 120 volts most of the time. Storms or no storms. The amber lights are cool, of course, and can be adjusted. The main blue lights can be dimmed, as well (and the middle one can be turned off entirely, if desired).

After unplugging my TV to plug it into the Panamax and then looking at the picture, I had to double check to see if my calibration-type settings had been reset (which would've been the TV's "fault" probably, rather than the Panamax's). Nope. They were the same. That "brighter" nicer-looking picture? That was simply the result of adding an M4300 to my system. I can only vouch for what it looked like in my basement: gorgeous. And THE SOUND. Played some music that had me in tears it was so nice. A worthwhile purchase.

Pros: Ease of setup. Looks. Noticeably improved picture and sound.

Cons: ?

Nice, Clean, Compact!

The M4300-PM is an additional unit for my home entertainment system, the other unit is a M5100-PM. I'm using the M4300-PM to power my subwoofer, stereo speakers, music hard drive and various accessories. It provides clean stable power as expected and there was a noticeable improvement in sound quality. The down lights are a nice touch but not everyone will be setup in a manner that allows them to take advantage of the downward lighting, in my case it is useful. However, it would be better if the unit had the same indicator light dimming capability that the M5100-PM features, which I feel is more useful as the blue indicator lighting is very bright.

Pros: Great performance for the dollar, worth the price when you want to protect your investment.

Cons: No way to dim bright indicator lighting.

Nice Product

This unit is a great little surge protector/power conditioner. To start, it just plain looks cool. It looks great with the cobalt blue display and the amber front panel convenience lights. But the true test is how well it protects your equipment while cleaning up muddy power. We have had a few storms pass through the area lately and all of my electronics have been well protected. We had some fluctuations in our lights as the storms passed but everything connected to the panamax stayed stable and happy. Just as important, the power conditioning has also improved the output of my equipment. The TV looks clearer and the sound of the surround sound is now crystal clear. I really believe if you are going to put money into a decent home theater system you need to put some money into protecting it from rogue power. This unit is well worth it's price.

Pros: Great surge protection and power conditioning, it will make your equipment look and sound better. Plus, the unit looks great.

Cons: None so far.

Great investment

This thing is made like a tank! Nice long cord and ample space between the plugs. meter is great, plugged in a vacume cleaner in a nearby wall outlet and turned it on. You could actually see the voltage drop on the meter but never below 120. the led downlights are more for estetics than useful, but nothing wrong with that, in my opinion. looks very cool. AND a great price!

Pros: long cord, very well made, works great

Cons: it'd be nice to be able to dim blue meter a bit but not a big deal at all.

Good Buy

Written By Mark, Virginia on Sunday, September 30, 2012

Glad I purchased this. Been watching it for months! Hooked up my computer, tv, sound bar, ps2, xbox360, wii, comcast, everything to this device and everything fits just perfect. The display lights on the front are cool and the usb/outlet port on the front are also very handy. Haven't particuarly noticed the picture improving but I had pretty clear picture to start with. Happy with the purchase and its nice having a guarantee on all my electronics and a nice looking unit.

Pros: nice looking, 5mil guarantee, lots of outlets, convience ports

Cons: none so far

Panamax M4300-PM

Written By Eric, La. on Saturday, July 28, 2012

Crutchfield Customer Review (What's this?)

The Panamax M4300-pm an excellent purchase for the price. It is relatively small However is very accurate in the readings and the picture on my television has cleared up dramatically as did allot of the distortion on channels of the radio that I normally could not hear what was being played. A Thunderstorm's lightning strike hit close to home and the protection was definitely there; It cut off all power immediately & restored it back to normal use within seconds; all of my equipment was protected and I did not even have to reset the unit!! If you are looking for protection (up to 5 million dollars worth) the price and unit is an excellent value!!!

Pros: Enough Jacks for someone who has between 0-9 hookups and each are clearly labeled and fully functional the display is constantly giving an accurate reading as to the voltage coming out of the wall and the protection is definitely there!!

Cons: None!!

Just In Time

Crutchfield Customer Review (What's this?)

When I moved to the Dickson, TN area I didn't realize I was moving to tornado and severe storm alley. I purchased one when I bought my new theater equipment for my new home and after a few storms bought a second for my other tv room. It give me a good piece of mind when a storm pops up and there's no way I can make it home to unplug equipment like I would normally do ..... and as I type this I can hear rain drops on my office roof. Time for another spring storm.

Pros: Great looking piece of equipment, Voltage reading and lighting options are very nice, Adds enough light in my movie room to move around safely with out turning on any additional room lights.

Cons: None that I can find

Well worth the peace of mind. The blue voltage display is quite cool also and will go well, aesthetically, with my Marantz receiver.

Pros: Everything

Cons: During the next bad thunder storm while I'm kicking back enjoying a good movie; let's hope not.

Clean Power-Hard to Say but nice to have organized

Written By Herb, Jackson, MI on Friday, February 03, 2012

Crutchfield Customer Review (What's this?)

I have absolutely no way to verify the real power management benefits of the M4300 unless something bad happens to my power which I hope doesn't. The unit looks to be well made with a quality feel to the controls. I only have audio components hooked in so can't vouch for the video benefits to say a TV picture. Although the little spot lights look cool they serve no use at all unless you are able to position the 4300 right where they can shine on something. But for some users it might be a feature that really appeals if they can use only the soft light they provide to illuminate their system. Maybe if the light dial swiveled! So you could focus the light where you wanted.

Pros: Allows you to organize your components into one power source with all the plug ins available. And power everything off with one switch. I did see that running a small room heater really dropped the voltage down and now use a separate circuit to run the heater that doesn't affect the music system.

Cons: If you have plugs with black box integrated you'll find it hard to position them in the rear plugs and won't have as many plugs open as you thought
