Our take on the Panamax MR4300

The Panamax MR4300 will protect your audio/video system from damaging power spikes as well as the minor day-to-day current fluctuations that can compromise your system's performance over time. It can safeguard up to nine components, and it also provides a protected front-panel USB charger for your smartphone, tablet or other portable device. Two front-panel lamps let you illuminate your equipment rack when making adjustments.

Clean, dependable power for your home theater

Panamax MR4300

You get nine AC outlets, plus in/out sets of coaxial, LAN, and phone line connections.

The Panamax MR4300 will protect your audio/video system from damaging power spikes as well as the minor day-to-day current fluctuations that can compromise your system's performance over time. It can safeguard up to nine components, and it also provides a protected front-panel USB charger for your smartphone, tablet or other portable device. Two front-panel lamps let you illuminate your equipment rack when making adjustments.

Top-quality picture and sound start with clean power

The eight rear-panel AC outlets are divided into two isolated banks to reduce inter-component interference and noise contamination. Four of the outlets accommodate high-current components like an amplifier and powered subwoofer. These switched outlets operate on a delay to prevent "speaker thump" when powering your system on and off.

The other bank provides four switched outlets for your source components, like a Blu-ray player. All nine outlets employ Panamax's Linear Level 3 noise filtering, which significantly reduces AC line noise. The front-panel digital voltmeter makes it easy to monitor the AC power coming into your system.

The MR4300 actually offers multiple layers of surge protection. Panamax's patented Automatic Voltage Monitoring (AVM) technology continuously monitors the incoming power. In case of an under-voltage or brownout (too little electricity), or an over-voltage (too much electricity), a flashing red lightning bolt illuminates and power to your equipment is automatically switched off. When voltage returns to a safe level, power to the equipment is automatically reconnected.

The other layer of surge protection is Panamax's exclusive Protect or Disconnect™ technology. This ultra-fast circuitry completely protects your equipment from catastrophic surges such as those caused by lightning. When that type of extreme event occurs, the MR4300 automatically disconnects AC power to your equipment.

Additional protection for coaxial, phone line, and LAN connections

The MR4300 also provides two sets of in/out coaxial terminals to shield your satellite, cable TV and over-the-air antenna connections. A pair of protected Ethernet jacks let you plug in your laptop and surf the web on a protected connection. And another pair of protected jacks prevents spikes from sneaking in through your phone line.

Protect Your Gear

Mike from Chicago, IL on 3/28/2018

Crutchfield Customer Review (What's this?)

I am using it with a 65 inch LG TV, Yamaha A-S1100 Amp, Primare Amp, satellite box, DVD ProJect Turntable, etc, etc... It just works. One bonus is it cleaned up all the wires in the back of the entertainment center console. I leave the lights off because I find the volt indicator a little too bright, even on the lowest setting.

Pros: Protects Your Gear Cuts down on noise in power line

Cons: Volt indicator light is a little too bright, even on lowest setting

Superior Product

Melany from Philadelphia, PA on 3/23/2018

Crutchfield Customer Review (What's this?)

This is a superior product! It meets all my specs, is sized appropriately, and the sleek design is a bonus.



Classy Protection

Baron from Boise, ID on 3/16/2018

Crutchfield Customer Review (What's this?)

Protection with style. Looks great, works great. Already had a low voltage protection event. Both Accent and Media lights have five dim settings to set the mood just right. Built better than I thought it would be. Excellent quality. The USB charging port has become very popular at my house. The grounding post is very stout and I've moved my Turntable ground from the receiver to this unit. Very happy buyer.

Pros: Excellent Quality Protection, Great price.

Cons: Not really a Con, but would be nice if the Media lights rotated 360.

Good Product

Michael from Bellevue, NE on 3/3/2018

Crutchfield Customer Review (What's this?)

This is my second Panamax Mr4300. I like the style and size of the product. After spending a lot of money for a system, you need to protect it. This last Father's Day in Nebraska we had bad storms. I ended up losing my subwoofer and phono preamp to power surges. I believe the Panamax MR4300 will stop this from happening again. It is easy to set up and may improve your sound and video.

Pros: Good style Good price Easy to use

Cons: none

Crutchfield Customer Review (What's this?)

I replaced an old Monster power conditioner that started to go bad. Researched several new brands and settled on the Panamax MR4300 due to all the positive reviews and features of this model. It's been working great for several months now!



Surprisingly effective

Anonymous from West Roxbury, MA on 1/4/2018

Crutchfield Customer Review (What's this?)

I was skeptical that this could be materially better than a good power strip, but I was very wrong. Just like that, the annoying 60 Hz hum has disappeared from my turntable inputs. In fact the noise level has gone down across the board. Really love the delayed shutdown feature for the high current outlets. Well worth the extra cost if you have expensive gear and want to get your money's worth out of it.

Secret sauce makes your gear look and sound better

Louis from Houston, TX on 12/8/2017

Crutchfield Customer Review (What's this?)

For several weeks now, I've marveled at how good the picture on my TV looks, and it occurs to me that I'm seeing one of the effects of the MR4300. The other effect that's a bit less in-your-face obvious, is that I'm not hearing hum from the electric lines when I turn up the home theater system or my stereo system. By filtering noise from the electric lines and isolating the high-current devices such as amps from the rest, this small, unassuming device makes your equipment deliver the best sound and pictures possible. It's nice that you can turn off the voltage display and the front panel lights, which I generally don't need.

Pros: Works well, easy setup


Panamax MR4300

Ken from Easton, MD on 10/12/2017

Crutchfield Customer Review (What's this?)

Needs vs. wants. Crutchfield advisors always help me not over spend on electronics. Lightning has hit my home theater three time over the past 25- years. I've protected the electrical system and used cheaper protection on the cable/internet, but lightning has always made it through the cable to blow out components. Most recently HDMI ports in the receiver were blown again! This Panamax MR4300 does exactly what was needed even though the more expensive Panamax had more grouped outlets which I wanted. Thank you advisors, you saved me money again!

Pros: Its compact design and ability to turn off the face panel. Also, I like the down lights that shine on the equipment below.

Cons: If the cabinet was one inch deeper there would be more placement options to stack equipment, if you do not have an equipment rack.

Worth the protection it provides!

Mark from Garland, TX on 8/20/2017

Crutchfield Customer Review (What's this?)

Flexible, functional with two power out banks, network, and coax ports as advertised that work well with my set-up - looks great in cabinet with gear, and illumination is nice touch.

Pros: Thin profile, illumination dimming, output options, equipment coverage/Panamax name.

Cons: Over priced, illumination tubes DO NOT rotate 360 deg. as advertised.....

Peace of mind

Troy from Cypress, TX on 7/27/2017

Crutchfield Customer Review (What's this?)

Immediate improvement of the picture! I would have never believed it.



Does the job!

Giuseppe from Rochester, MI on 7/26/2017

Crutchfield Customer Review (What's this?)

Easy to install, small and slim fits perfectly in my media console. Easy set up for the lights, easy to control, so I can indeed dimm them all the way off for complete darkness. I plugged 1xOppo 203 Blurayplayer, 1xVizio 70", 1xMarantz AV 1603, 1xPS4pro.

Pros: size and reliability of company

Cons: maybe it could be 50$ cheaper

Seems to be working correctly. Have a 55 lg oled tv. Yamaha aventage receiver. Samsung ub 8500 ultra hd blu ray player. I'm happy I know I'm covered if struck by lightning again.

Pros: Looks good. Can turn off all lights and go black.

Cons: Price.

Panamax MR4300

Tom from Ketchum, ID on 5/2/2017

Crutchfield Customer Review (What's this?)

Perfect size and functionality for a small to medium home entertainment system. Needed a compact power conditioner/surge protector to fit in discrete space and this product fit the bill. The construction is sturdy and the controls are simple and aesthetically pleasing.

Pros: Compact size, simple setup, and good looking

Cons: None

Not good!

Joseph from Red Feather Lakes, CO on 4/14/2017

Crutchfield Customer Review (What's this?)

Total piece of junk! I bought this several months ago after I moved and upgraded my whole entertainment package. Never used one of these but was talked into adding this to my purchase. My new receiver gave me nothing but problems. Six to nine months later my new speakers still have line noise in the form of static and popping. I finally found the source, this Panamax mr4300. Save your money and just use a power strip with surge protection.

Pros: None

Cons: Waste of money Junk Does not work Will not use again A paperweight

Crutchfield Customer Review (What's this?)

Very simple device and easy to access and connect all inputs. It's also great looking and complements my audio components. Highly recommended to protect your audio and video system against power related conditions (i.e.surges, power failures and drops) from damaging your equipment.

Anonymous from Niantic, CT on 3/5/2017

Crutchfield Customer Review (What's this?)

Not much to say, it's a surge protector. Seems to work, but haven't tested (thankfully) the surge protection.

Pros: Adjustable component lights and extra outlet on the front are a nice touch.

Cons: None yet

Noticeable audio and video improvement.

Michael from WV on 12/26/2016

Crutchfield Customer Review (What's this?)

I must admit I didn't think that I would notice much change in the sound and video signals after hooking up all of my components, but I did. I have Sony 60" tv, a Onkyo TX-SR707 receiver, Polk 12" Sub-Woofer and 7 Polk surround speakers, and two older Boston Acoustic front mains, a DVD player, 2 CD players, a turntable all plugged into the Panamax. First off, I did notice the video was a little crisper, but most of all I did notice a cleaner sound through all of my components. Nothing major, but enough that I could tell. The peace of mind of the surge protection is also a big plus, if it works as described it will be great. My only complaints with this unit, and they are minor, are the volt meter read out is a bit too bright (so I leave it off most of the time). It has 5 settings and the lowest could be one more notch lower. The only other issue is it would be nice if the media lights would rotate 360 degrees. Also, I wish it had an HDMI cable out. Other than that I am quite happy with my purchase, and would recommend adding it to your system. A final note, I wanted to buy the M5400-PM but I didnt have the extra funds at the time and wanted to get some protection now.

Pros: Easy hookup, compact size

Cons: No HDMI cable output.

how would you know

Anonymous from Lawton, OK on 12/4/2016

Crutchfield Customer Review (What's this?)

It is difficult for me to evaluate effectiveness. There are no observable problems so I must assume it is doing fine. A high end audio shop Audio Concepts in Dallas said it did not protect the components well. Perhaps they are biased. Perhaps Crutchfield is biased. Happiness is an objective, unbiased evaluation. I am curious and have talked to more than several people about this product. Another hifi shop in Oklahoma City did not like or recommend it. Magnolia at Best Buy in Oklahoma City sells Panamax.

Pros: no issues to date

Cons: others do not like it

Good purchase

Kevin from Nashville, TN on 12/2/2016

Crutchfield Customer Review (What's this?)

I bought this mostly to protect home theater equipment which I have spent a bit of hard earned $$$ on. Sonos, 4k etc... I read it could potentially improve sound and video quality as well. I definitely notice a little sound improvement which is incredible since I thought it was already pretty good. Nice looking unit and good build quality. Very simply operation. Plug in, turn-on, attach electronics, done. If the surge protection works as advertised it's good to know my equipment is well protected.

Pros: Easy operation, looks great. Good protection guarantee.

Cons: None yet.

A must have

Power stabilizer from Lacey, WA on 9/17/2016

Crutchfield Customer Review (What's this?)

Great for any equipment that you want to protect

Pros: Protects you investment


Really Makes a difference

Greg from Annapolis, MD on 9/2/2016

Crutchfield Customer Review (What's this?)

I never thought this would help and would just need it for power protection. I put off buying this for a while but when I connected everything to it you can notice a difference right away. I should of bought this sooner. Takes the audio and the quality of the video to the next level.

Pros: Cleans the power and protects your equipment, Warranty on all your equipment plugged in.


A neccessity, not an option.

Joe B from Putnam, CT on 7/24/2016

Crutchfield Customer Review (What's this?)

Why spend $300 for a piece of equipment that just "sits there?" Watch the video of a Crutchfield advisor with a rep from Panamax to see exactly what these power management/surge protection units do. This is really not an optional piece of equipment. It is a must have. Getting the noise out of the power going to your components and display is critical for the performance intended from the products. Who would put bargain basement oil and gas into a high end car? Why would you do it to your TV and AV/Stereo equipment. I purchased this particular model after talking with a Panamax rep on the phone. Purchase really is a no brainer.

Pros: Clean power, excellent surge protection capabilities, Crutchfield is one of the few authorized dealers (by else where and the $1.4 million warranty is void).

Cons: N/A

excellent protection

Pat S from UT on 7/1/2016

Crutchfield Customer Review (What's this?)

I bought this power manager for our new theater room and it works perfectly, the front panel displays the current level coming into the unit and it does an excellent job of smoothing out power fluctuations especially in the summer when there is a large draw on the grid with a/c units and swamp coolers running, and it provides plenty of inlets for all of your equipment and devices. Overall this was a Great investment!

Pros: front panel displays the current coming into the unit, the unit is very small

Cons: none

So far, so good

RD from Columbus, OH on 3/24/2016

Crutchfield Customer Review (What's this?)

It's doing it's thing.... Hopefully it never Needs to take a surge!

Pros: Slim, well lit

Cons: Only one port for ethernet. A second port would have been nice, as receiver and Xbox both need it.

Sound Clarity

Cons: None

Panamax CS Not Any Help

Don from Tallahassee, FL on 12/3/2014

Purchased the MR4300 from Crutchfield and everything was fine. Then after about 3 months the unit started "buzzing" internally. Sent to Panamax (Core Brands) and they said it tested out in spec. I asked if they had a Spec for "buzzing" and got no reply. Unit was sent back to me with problem unresolved. Although the unit functions as it should, it is annoying to hear the "buzz" as I walk by stereo system. Won't buy another Panamax product.

Pros: Pretty to look at

Cons: Pretty bad customer service from Panamax

Panamax MR4300

Michael J from New York on 11/11/2014

Crutchfield Customer Review (What's this?)

I've read a few reviews where some have said that their picture and sound had noticeably improved after hooking up the Panamax, but I can't really say that I've noticed that much difference on my end. Even though that's not really a deal-breaker, or any reason "not" to purchase this product, because I feel confident that all my components are fully protected using the 4300. The sleek design and looks of the 4300 are also a nice complement sitting next to all my other equipment. I believe 4 stars is an excellent score for this product, and had it improved my picture and sound that much-more, I would of scored it 5 stars without any hesitation. As usual, Crutchfield shipping was right on schedule to New York.

Pros: Very easy to setup. Just plug-in your equipment, and then plug in the main power.

Cons: None.

line conditioner

panamax MR4300 from Sacramento, Ca. on 8/16/2014

Crutchfield Customer Review (What's this?)

the product seem to help improve on the picture and sound just a bit, other than that I can't tell. I like the fact it's a line conditioner and power protecter all in one and it looks good with my other equipment.




Hands-on research

Product Research


9 Protected & Filtered Power Outlets: The Panamax MR4300 features 1 front-panel "Always On" AC outlet, 4 rear-panel "Switched Linear Filtered" AC outlets, and 4 rear-panel "Switched High Current" AC outlets. All of the AC outlet (front & back) include surge protection and power filtration.

  • High Current Outlets: The unit's 4 rear-panel High Current outlets in Bank 1 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. These outlets can be switched On or Off.
  • Linear Noise Filtration Outlets: The 4 Linear Noise Filtration outlets provide a two stage tapped Pi filter circuit for each outlet in Bank 2. These outlets can be switched On or Off.
    Front-Panel AC Outlet:
    The MR4300 features a protected and noise filtered convenience outlet located on the front-panel. Perfect for temporary gaming systems, portable electronics (such as music players or smartphones), or other personal electronics. This AC outlet is Always On.

Protect or Disconnect Technology: The Panamax MR4300 employs exclusive Protect or Disconnect technology for surge protection. This ultra fast protection circuitry completely protects your equipment from surges such as lightning. When overwhelmed with extreme catastrophic events, Panamax permanently disconnects AC power to equipment.

Level 3 Power Cleaning & Linear Filtration: The unit's Level 3 Power Cleaning and Linear 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 Voltage Monitoring (AVM): Panamax's patented Automatic Voltage Monitoring (AVM) technology continuously monitors the incoming power. In case of an under-voltage or brownout (too little electricity) or an over-voltage (too much electricity) a flashing red lightning bolt will be displayed and power to the equipment is automatically turned off. When voltage returns to a safe level, power to the equipment is automatically reconnected.

Signal Wire Protection: Protecting a complete home theater system requires that signal wires coming out of the wall be protected as well. Universal ultra low-loss coaxial protection, as well as LAN/Ethernet protection prevents signal lines from carrying damaging surges while maintaining full high-definition and high-speed Internet signals to your equipment for your connected life.

  • Telephone & LAN Surge Protection: There is one RJ-45 input and one RJ-45 output for 10/100 baseT Ethernet lines, plus one RJ-11 input and one RJ-11 output for standard telephone lines. LAN protection allows for 10/100 base-T Ethernet equipment to integrate into an audio/video system without the risk of upstream surge damage from a gateway, switch, router or other network device. Telephone protection protects your incoming telephone lines.
  • Cable & Satellite Surge Protection: There are two gold-plated coaxial inputs and two gold-plated, threaded, female coaxial outputs for connecting your satellite, cable or antenna TV signal lines. Coaxial protection circuits prevent damaging surges from entering through signal paths and have the smallest signal loss on the market; less than 0.5 db of attenuation from 0Hz to 2.2GHz. Panamax coaxial protection has been specifically designed to virtually eliminate signal loss. The clamping level of 75V will meet and exceed the demands of both cable and satellite voltages while minimizing exposure to damaging spikes and surges.

Digital Voltmeter: The MR4300 features a front-panel Digital Voltmeter which monitors the voltage supplying your home theater equipment. If line voltage drops below 95VAC, or if the line voltage exceeds 140VAC, the display will turn off and the "unsafe voltage" indicator will flash indicating and unsafe voltage condition.

USB Charging (0.5/5V): The MR4300 features a front-panel USB (type-A port) rated at 0.5/5V for charging your Apple iPod/iPhone, Android smartphone, or other USB-enabled electronic device.

Media Lights: The Panamax MR4300 features front-panel rotating and dimmable media lights that help illuminate your equipment in your AV rack or cabinet.

8' Power Cord w/ Low-Profile Plug: The Panamax MR4300 is fitted with an attached 8' power cord w/ a low-profile IEC 3-prong plug. This 45° angle low profile plug allows your equipment to be as close as it can get to the wall outlet while not blocking an adjacent outlets. The 8' power cord means your installation location isn't restricted by wall outlet location.

Circuit Breaker: A circuit breaker is located on the back panel of the MR4300. 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 MR4300 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. For coverage conditions and information on how to make a claim, please see the warranty sheet.

If you have a component that requires a separate ground connection (such as a turntable or powered subwoofer, for example) then you can use the "ground lug" terminal on the MR4300 to safely ground it. For more details or to discuss further please feel free to contact an Advisor directly by phone (888.955.6000) or online chat. Thanks! [ Larry  Feb 06, 2018 ]  Staff
I selected the high current bank of outlets for my receiver, external amp & powered subwoofer. I use the other bank for my Blu-Ray player & DVR. I interpreted the designation of banks as a means to separate outlets intended for amps from media players. Although I haven't tried a different configuration I'd bet it wouldn't make a huge difference either way? [ stickywicked447  Jan 10, 2018 ]
Only put the receiver in the high current bank. Put everything else in noise filtering. [ David  Jan 09, 2018 ]
Mine reads 118-119 for a majority of the time. [ House  Apr 07, 2017 ]
In a 120 volt AC system the "A" stands for alternating. It is normal for the line voltage to be anywhere between 110 and 130. [ Brian F.  Apr 07, 2017 ]
120 is nominal, but I live in a rural area that has old power lines that go out a lot. I see my display indicate as low as 114 during rain or snow, and as high as 126 when dry low power demands. I have seen this thing save my HT system multiple times such as the occasion of a large tree falling on a power line. [ MICHAEL  Apr 07, 2017 ]
My devices (3) fluctuate from 119-121. I do not recall ever seeing 123. [ JOSEPH  Apr 06, 2017 ]
PG&E has a good capture of the voltages in this country pge_dot_com/includes/docs/pdfs/mybusiness/customerservice/energystatus/powerquality/voltage_tolerance.pdf Basically states: Range A service voltage range is plus or minus 5% of nominal (looks like about 110 - 124.5V) Range B utilization voltage range is plus 6% to minus 13% of nominal (looks like about 106 - 127V) But take a look at the PG&E link and apply the information that is applicable to your area. [ David  Apr 05, 2017 ]
Voltage fluctuates in all homes. The power company tries to hold it +- 5% of a nominal value but it really can be +- 10 % easy. I have seen a nominal 120 VAC fluctuate from 100 to 145 volts. If the power company has lines and equipment that are loaded toward the maximum capacity, fluctuations will be greater than if they are lightly loaded. [ Mike  Apr 05, 2017 ]
That's normal. Voltage fluctuates. [ Jordan  Apr 05, 2017 ]
Since we're talking about "Alternating Current", it does fluctuate several volts up and down. I've seen mine as low as 117 VAC and as high as 123 VAC. That's a normal span, according to what my electrician friends have advised. You're fine. [ Johnny  Apr 05, 2017 ]
The Panamax MR4300 will handle all those items as well as a few more. I have a PS3, LG UHD 49", Def Tech SW 1500 Watt, Def Tech center channel with 300 watts built power sub woofer, and 2 Definitive Technology ST8060 Towers that contain 300 W power amps in each tower. Driving all this is a Sony STR- DN840 7.2 h 150W/ channel 4K HD receiver. plus the Directtv box, and the modem and power supply.. I feel confident with the protection I have. [ MICHAEL  Apr 07, 2017 ]
I recently purchased and incorporated the Panamax MR4300 into my home entertainment system. It's only been in use for about 2 months but it's been great so far. The components I have connected to it are a 42" LCD HDTV, Onkyo TX-NR717 receiver, Sony BDP-S6200 blu-ray player and a 600 Watt powered dual 8-inch subwoofer. I have had no issues powering my system. I live in a fairly remote location that is often susceptible to power surges and power outages during storms. The digital voltage display provides great peace of mind, knowing exactly what power my system is getting and that all of my components are protected. It is also nice to be able to turn the power off to all of the components by simply pressing a button. The display can be dimmed or completely turned off while in use if it's in a visible location. As to your question regarding the power consumption of your system. I'm not sure how to find that out, but I would guess the MR4300 will handle it just fine. I do know that most electronics have a sticker/label on the back showing their power consumption. You might be able to do some math from that. If not Crutchfield has some of the best customer service on the internet. [ MICAH  Jan 06, 2015 ]
I have this unit. I bought it as insurance. I have no idea if it "works" or not yet, as nothing bad has happened. However, I do have my entire theater system running through it - Projector Receiver/amp Blu-Ray Cable box HDMI splitter LED stage lights Light board Sound mixing board 2-channel Karaoke amp (Dad of the year according to my daughter for the previous 4 items) 2-Channel amp for speakers in other rooms Maybe a couple other things This powers them all without a hitch. I figure that since most homes use 15 amp breakers, and this unit is rated for 15 amps, it can run as many things as your circuit can realistically handle. [ Tim  Jan 06, 2015 ]
Hi Allen. Unfortunately, I can't really answer your question. I do not have my powered subwoofer running through the conditioner. My subwoofer is on another wall plugged into a separate outlet. That being said, I have a 65" plasma 3D TV, an Arcam receiver (7x100), a cable box, and a blu-ray player hooked up through the conditioner. I have experienced no problems with it. I hope that helps a bit. [ kenneth  Jan 05, 2015 ]
Hey Allen. Currently I have my Sony 55" t.v., Yamaha receiver, Xbox One, PS4, Xbox 360, and a WII U all plugged into my MR4300, and my subwoofer is plugged into a wall outlet next to my entertainment center. When I'm running at least (3) components at once, there's "very limited" power consumption. My 4300 always indicates (120 VOLTS) on it's display, and the the lowest amount of voltage that I've ever seen when all my devices are running at once is (118). It fluctuates voltage back-and-forth all the time, but I don't see why you'd have any problem(s) using a 4300 with your home theater set-up having your sub plugged in as well. Good luck. [ Kathleen  Jan 05, 2015 ]
I can't say for certain... But I am putting this sucker to work with all the components attached. Marinate AV Receiver, Blue Ray, Klipsch Powered sub, DTV, Xbox1, and more... This sucker has been no problem whatsoever. Can't say about the protection, because thankfully, I haven't needed yet. All-in-all... Its a good piece of equipment. [ CULLEN  Jan 05, 2015 ]
Thank you kindly sir! I'll give it a try. [ Allen  Jan 05, 2015 ]
Allen / The operating power requirements of these components are quite low . I have as many or maybe a couple more units plugged into my Pmax w/ no issues . The power consumption of electronic components is not shown in the mfr's specs unfortunately . G [ GERALD  Jan 05, 2015 ]
