    does is support 240v (global voltage) ?
    New User U on Dec 10, 2016
    BEST ANSWER: The amplifier can work in the 240V world if you use an external transformer to convert your native 240V to 120V. Keep in mind that the external transformer should be capable of 15 amperes of current.
    I have been trying to purchase this for over two months, the ETA date comes and then it just gets updated to a later date, and so on and so on....Can we just get a realistic and factual date please?

    What is the input sensitivity of this amp? I know that many amps need a preamp output voltage of at least 2 volts to make their rated power....many people will use an amp like this with their AVR as the preamp and most AVR's only have a preout voltage of .75-1 volt which isn't a strong enough signal for the amp to really perform as it should...
    A shopper on Mar 15, 2017
    BEST ANSWER: The spec sheet on the amp says an input sensitivity for full power is 1.6 volts. The amp is built by ATI, who have been in the business for a long time. I use the amp with my Marantz 7702A pre amp which has an audio analog output of 1.2 volts unbalanced and 2.4 balanced. The digital output is 2 volts at 0db playback. Those specs were identical to a Denon AV 3311 receiver that I had also used as a preamp before the Marantz. I can tell you that the amp seem to perform well with both pieces.
    what is the gain of the amplifier when using the xlr inputs? This looks a lot like the ati 7700 and the gain of that amplifier it too great to work in my system.
    A shopper on Mar 4, 2018
    BEST ANSWER: Low noise floor and less interference from other cables use an XLR cable. Compared to using RCA cables. This usually happens when running to several pieces of equipment what cables are close to each other.
    I HAVE A DENON MOD.#AVR-4310CI THIS REC./AMPLIFIERHAS AN ISSUE WITH OVERHEATING WOULD THE MONOLITH#14566 7X200WATTS PER CHANNEL TAKE CARE OF THIS PROBLEM?
    william m on Jan 7, 2017
    BEST ANSWER: With respect to your inquiry regarding the Monoprice Monolith Power Amplifier and the Denon, I can offer a few comments. First, I have had two Denon receivers, the most recent being the 3311CI, a very capable unit. I used it for years as a stand-alone receiver, then more recently as a bi-amping pre-amp for the Monolith. I’ve had no concerns concerning overheating. Assuming your 4310 is not malfunctioning (e.g., a problem with the power transformers), it’s difficult to know why and to what extent your unit seems to be running too hot to you. There are obvious possibilities such as inadequate ventilation around the receiver, items blocking the vent holes around the case, and driving the receiver at high volumes for too long a time. You’ll want to be sure to rule those out. Your receiver provides 130 watts into 8 ohms for two channels, so you have a goodly amount of power for your speakers.
    As for the Monoprice power amp, I’ve been using it daily since last May and it’s been performing very well. I’m certainly not an electronics expert, but I have not noticed it producing any remarkable “cooling ease” on either the Denon 3311CI I had been using with it nor on the Marantz 7702 mk II, which I now use as a pre-amp with the Monolith. I can report the Monoprice has performed admirably and for its comparatively low price, the 200+ watts per channel of serviceable power is a fine bargain. I do quite a bit of 2-channel listening and am not terribly interested in an Atmos configuration, so I use its seven channels in a 5.1 surround system, utilizing the two extra channels in a bi-amp configuration with my Vandersteen IICE signature 2’s. I’ve been quite satisified.
    How long is the power cord on this amps? thanks

    BEST ANSWER: I think it's either 6' or 8' long. I have too many speakers, wires & electronics in the way to tell for sure. Either way, it didn't reach my outlet, so I used power surge strip, of which Monoprice has many. Here's a good one, for example: https://www.monoprice.com/product?p_id=11146. I love, Love, LOVE the amp. I have the Monolith 5 (200x5) and an Emotiva XPA-5 Gen 3 (250x5) .... I prefer the rich, powerful sound of the Monolith over the Emotiva...just my two cents.
    Has anyone had issues with a periodic buzzing sound emitted from both the amp itself and the connected speakers? The amp itslef is on its own dedicated 20 amp circuit (I also tried another circuit) and I have tried it with and without some power filtering strips. I have also tried the Emotiva CMX-2 which is supposed to remove both noise and DC offsets on the line and it did not appear to help. I was also able to notice the amp buzzing with no inputs connected so I know it is not a source issue.
    Chanz M on Jun 11, 2017
    BEST ANSWER: Try disconnecting the hdmi from your cable/satellite box. A lot of those introduce a ground loop hum into the system. I had the same issue. Solved it by unplugging my DTV box when not in use.
    Does Monolith make a preamp? What are you people using to control this amp?
    Robert C on Sep 8, 2017
    BEST ANSWER: I wish monoprice make preamp. I'm using my Boston acoustic receiver and it bring the amp able to fully utilize my hunger power speakers.
    Is this a fully balanced design?
    Manish P on Mar 27, 2018
    BEST ANSWER: No it is not.
    are owners of the monolith seven simply plugging into a standard wall outlet? would it be ideal to run a designated 15 or 20 amp line? I am concerned about this since I have a 65" plasma, a powered svs pb13 ultra sub, and a polk center channel which has its own powered sub, and an onkyo receiver which in this application would by pass the on board amps. I would appreciate any input on this subject.
    Byron C on May 9, 2017
    BEST ANSWER: I asked myself this same question before I bought the Monolith 7. I did some research on the internet and satisfied myself I'd be OK. After all it is unlikely that you will ever have all 7 channels operating at the full 200 watts simultaneously - I suspect that will never happen. My situation is a bit better than yours in that I have dual 20amp circuits feeding my AV equipment. I have the amp and my preamp sharing one circuit. I have had no hint of trouble.

    Overall I am very happy with the punch this amp delivers to my speakers. And the price is hard to beat.
    Is the trigger cable just a normal 3.5 mm cable?
    Chris W on May 1, 2017
    BEST ANSWER: Yes it is. 3.5mm male to 3.5mm male (on my pre-amp).
    Is the power rating listed for all channels driven or just 2 channels driven on the 5 and 7 channel models?

    Is the front label silk screened on crooked like in the photo ad?
    Ronald W on Feb 3, 2017
    BEST ANSWER: Lol, I think that is just an illusion because of the angle of the photo. The thing is a tank, clean looking, sleak, and a powerhouse. I don't regret the purchase
    I'm only running a 5.1 system. Can the 7 channel be used to bi-amp the front channels?
    Richard B on Nov 3, 2017
    BEST ANSWER: You need to have a receiver that has bi-amp capabilities and has rca outputs. The amp has 7 rca inputs so it doesn’t care what you put into it. It will power whatever you have plugged in. I really have enjoyed this amp, but it is SUPER heavy. So be sure you have a place to put it and a friend to help you get it there.
    Where is this amp manufactured?
    Keith L on Sep 22, 2017
    BEST ANSWER: It's made in Montebello, California.
    Can this amplifier be put in an enclosed AV cabinet/rack that has an exhaust fan at the top?
    A shopper on Jun 9, 2018
    BEST ANSWER: I have mine setting on the floor, however you could put it in a cabinet if the cabinet can hold the weight of 100 lbs. My unit run pretty cool, I have a hard time keeping my cats off of it - I don't see a problem with what you are planning for your installation - hope this helps!
    My preamp has both L and R XLR and L and R RCA jacks. for all 7 channels... The Monolith 7x200 only has a single RCA Jack and a single XLR jack. Is this a MONO Amp?
    Rex T on May 14, 2018
    BEST ANSWER: What? The device has 7 RCA jacks on the back and 7 XLR jacks. There is no model that has only one Jack on the back.
    Has anyone seen the mythical creature known as the Monolith Seven in the wild? I have been searching high and low for 6 months now. Each time I hoping to catch one in the wild. I have been promised sightings many times, four exactly, during that time and have still yet to see one. I'm starting to think this beast is one of legend like big foot!
    Michael P on Apr 27, 2018
    BEST ANSWER: I have finally found one! It is MINE! I will find out if this beast does what Monoprice and the reviews and the owners and just about everyone says about it.

    A Beast of an amp in every way
    This is a beast of an amp. I come from the generation where weight equals quality. If that is still the standard, this must be the best amp ever (according to my back).
    Really for the price and you what you get for it, you basically would have a hard time doing better. Would you even hear the difference at the twice the price? Few if any could.
    Being a Steely Dan fan, I put this amp through the paces and it did the job. Detailed, accurate, and powerful. No hint of color to the sound!
    Movies were next and I turned it up to 11 (actually probably closer to 4) no problem. Never felt like it was fatigued. Heck I wondered the monolith was laughing at me saying "...that's all you got?!".

    Well after 50 years my ears are not what they used to be but there but there's certain songs and movies that I know very well and the monolith did the job excellently and managed to just get out the way.

    Hookup was nice. The trigger input was also a nice touch, especially the fact that it accepted a low voltage of ~3v which is unusual as most are 9v+. This allows one to use USB on those receives (like Onkyo) that lack triggers for the primary zone.

    The back panel has lots of room and laid out logically. Made it easy to hookup.

    PROS: Neutral high power sound. The very definition of clean power and provides the headroom I've been looking for.
    Quality at an excellent price.
    Did I need 7 channels. Heck no! But you know what they say,buy the biggest amp you can, you will grow into it (maybe that saying is about buying a home...oh well).

    CONS: Not really cons, but you know, you gotta complain about something!
    :
    It's really Heavy. I couldn't lift it entirely. Used a dolly to get it into LR and then one side at time into entertainment center.

    Runs Hot - yeah, all electronics do, but this one is really hot. Not surprising. Unless you run this in an open rack, plan on adding some low noise fans on top.

    Doesn't keep my beer cold.
    Scares my cat and pisses off my wife when in use.
    Can't charge my Tesla.

    The Best Game-changing Value in Home Theater. Period.
    Remember that time you finally splurged for that first high-end AVR, only to have the "next best thing" hit the shelves a month later? …and it typically didn’t flaunt inherently better sound quality, but rather convenience features and format adaptations that almost solely necessitated any new models at all? Whether during the transition from AM to FM, VHS to Laserdisc, or HD to 4k, from before Lennon's death to after Prince's, it's a club in which far too many of us are members.

    Enter the concept of the dedicated AV power amp. Only a few short years ago, you wouldn't even dream of playing with the big boys in this arena unless you had something red and Italian in the garage (other than a Vespa), and an extra zero in your system budget. Monoprice's new Monolith series brings this very concept to a whole new bevy of consumers, myself included, and with no compromises. Now one can pick up their choice of Monolith for a song and trust that in 40 years, the Monolith will not only still perform as it did day one, but with its absolutely audiophile-grade Class AB topology for the true aural addict, will still be at the upper echelons of quality such that one's children would be all but spoiled to inherit it.

    With the Monolith keeping your sleep sound and upgrade-itis at bay, you’re simply left to keeping up with the technology Joneses via modest receiver or pre/pro investment every so often. When Sound & Vision's David Vaughn lauds the Monolith as a bargain, it should be all the reason you need to jump… If you need a little more incentive, wait occasionally for Monoprice’s discount emails, and pray it applies to the Monolith series – a rare, but worthy payoff for your patience!

    I almost forgot… As far as the product itself, there’s little more to be said than what David Vaughn wrote in his article. Yes, the Monolith stupid-heavy, it will run hot - I’d also measured standby power draw around 160W, and yes there’s the modest price of admittance if you’ve not prior considered the concept of a separate amp, but I’d bet a testicle (I mean, who really needs two?! Lance “Juan Pelota” Armstrong has how many kids now??) that Unicorns have been sold for less than what this amp delivers.

    It’s. That. good. My listening friends, my girlfriend, and my Axiom M80v4 HP’s agree, and I think you will as well. Plus, it’s American-made to boot! Make America great again?! Monoprice for President!

    …and Monolith for your next upgrade.

    PROS: - Audio bliss at seemingly limitless power levels, especially with a dedicated 20A circuit driving low-impedance loads.
    - Absolute. Fuggin. Bargain.
    - Too heavy to steal.
    - Trigger and soft start features are nice touches.


    CONS: - Almost too heavy for your girlfriend to lift into place for you. Almost. Should actually be a wifey test. If she can, add a tick mark to the "put a ring on it" column.
    - Lack of XLR inputs... but I say that in jest. Unless you're running 100ft signal cables and/or reproducing content with over 120dB in range, let alone a pre/pro that can reproduce it, this is by far the dumbest "con" ever. Plus, most XLR inputs are not truly balanced, and all but the most insanely priced, high-end pre/pro's do not incorporate TRULY balanced outputs either! Do the research and you'll see, XLR's are basically a gimmick outside of pro audio applications.

    One of the Best and Most Affordable Multichannel amp for the Spec
    This could be the best 7 channel amp at this price range. Specifications for this amplifier are compared to the amps with at least double the price of Monolith 7. I'm sure one can spend hundreds or thousands more on a separate 7 channel amp, but law of diminishing returns will come to play at some point. With Monolith specs and sound quality means you can save a lot of dough and can spend it on better speakers. Dialogue reproduction is a key for any amp, and the Monolith 7 is exempalary in this regard. This amp is an incredible steal...

    If I'm critical of few things, then (1) the amp runs really really hot. After about an hour of operation, the heat gets to a level that you can burn your hand over it. Definitely, need a separate AV equipment cooling system with this amp. I placed AC Infinity 17-inch wide S8 fan over it, and it runs cool and perfect. (2) back panel of the amp indicates "Designed and Engineered in USA", but it does not indicate where it was manufactured. One could easily think that the amp is manufactured somewhere in China or India to keep the cost low for the spec. However, after doing some research, it is actually manufactured at the ATI facility in the Sunny ?? Southern California..Monoprice should definitely consider stamping "Made in USA ???? " on the back panel of the amp. ATI manufacturers hog-end amps and this should definitely be a plus for Monolith (3) lack of balanced inputs..

    Overall, best sounding amp. This amp will give Emotiva or Outlaw run for its money.....

    LOVE IT!
    Needed a new receiver and was willing to spend some money, but couldn't turn down the DENON AVR-X4200W when the price dropped to $700. Quite a bargain, but only offering 125wpc X 7. Decided to check out power amps, and was amazed to read about the MONOLITH 7.....great power @ 200wpc X 7 with all channels running.....great price......and great reviews from Audioholics! The only negative was that it generates some heat. Decided to jump on it, and, first of all, the heat isn't a big issue. I have it in a rack with some ventilation space around it and all is well. Man, when I cranked that beast on, my B&W 804's and B&W HTM 1 center popped like I had never heard before! Lots of punch in my music now, and movie soundtracks are a blast! It's a big, bad dog for the price and a good warranty. I like that MONOPRICE seems to be offering good quality and value at a very fair price! I heartily recommend!

    A well-built product
    After having read some of the positive independent reviews I decided to order the Monolith 7 and use it for my theater room. Driving all 7 channels is effortless with this amp. The build quality is top notch. The trigger is a great feature which I'm using from my Denon receiver to automatically turn on the amp. I measured the idle power (i.e. turned on but with no input signal) using a kill-o-watt meter and it is around 160W. So you'll want to make sure it is in a well-ventilated location.

    PROS: Build quality
    Sound quality


    CONS: Weight
    No balanced inputs

    Replacing my GFA-7705
    My Adcom GFA-7705 had given up the ghost a few weeks ago and it wasn't worth repairing (4 of the 5 channels were dead). I got the Monolith 7 for a bit of an upgrade (plan to add Atmos / DTS:X in near future).

    After hooking it up it sounded better than my adcom.

    Better directionality of the sound effects on my goto demo disks, didn't muddy the sound stage as volume increased and it just sounded more detailed.

    Pros: Cheaper, better sounding and more channels than my previous adcom

    Cons: Heavy as $@*!, but that is typical of something of this build quality.

    Monolith 7
    I just wanted to add this to my previous review. Though the manual and other documentation states the binding posts are 5 way, beware they are NOT. Those of you who use spade lug connectors will have to purchase banana plugs which will allow you to use your spade lug terminated cables. This was a bit of a PITA once I got the amp home and started to connect up all of my speakers..

    Great value for a superior piece of equipmnet
    I have the Polk RTI series speakers (2- RTI A9 front , 2-CSi A6 center, and 4 RTI A3 surrounds) plus 3 SVS and 1 Def Tech powered subwoofers and a 65" LG OLED TV in my HT system. I thought it sounded pretty good powered by my Yamaha RX-A3040 at their proclaimed 150 wpc. But with this new beast of a power amp (93.2 lbs.) it has taken the sound depth and clarity up to a different level. Sure it's hard to move all that weight around to where you want it, but once you get it in place and connected, the results are superb. You'll realize instantly what a great purchase you have made upgrading to this audiophile piece of equipment that is so solidly built that it should last for many years beyond the warranty. There's no buyer's remorse here, just gratitude for such a great value. If you choose to buy one, I think you'll find the monolith exceeds your expectations. It did for me.

    I have finally gotten around to upgrading some of my home theater equipment. I was intrigued by this behemoth of an amplifier, and I freely admit I am not a true "audiophile." I built my first power amp about 45 years ago (Dynaco 400) and have always appreciated brute power with massive heatsinks. That drew me to the Monolith.

    I liked the idea of no fan (quiet) and the "anti-thump" start up. I received the box (double boxed) and yes, it is a massive beast. I was able to get it out of the box myself, but I would not recommend it.

    I have not really had a chance to assess its sonic qualities much yet (I will try and update this as I go), but can attest the unit arrived in perfect condition, extremely solid, and worked perfectly the first time powered up. I have it coupled with a Marantz premium 11.2 pre-amp (model escapes me right now, but it is the one for about $2300). The low voltage power-up interlink works perfect, and there will definitely be some heating support from the unit this winter (it was not super hot, but you can tell it is creating heat that the massive heat sinks dissipate).

    Sound quality seemed extremely solid to start, but like I said I haven't really had time to assess the nuances yet (been working too much!).

    What I wanted to get across in this basic review was I think it is a tremendous value, very solid, Monoprice delivered quickly and professionally, sounds great, and works flawlessly.

    PROS: Value
    Quiet
    Solid
    Sounds great
    (if you were ever burglarized, I guarantee the thief would not be running off with this amp unless they brought a dolly!

    CONS: No "balanced" inputs, if you really need that.

    Monolith 7 Amplifier
    Just received the amp its great!! Sounds very open and doesn't run out of steam when driving my 4 ohm speakers. It’s still breaking in so I'm sure the overall tonal balance will improve with time. If you're looking for the biggest bang for your buck for a home theater amp, this is it!! Word of caution, carefully plan were you are going to install the amp, 1) it's pretty heavy (100+ LBS) and 2) needs proper ventilation on the top and bottom, it can run pretty warm so tight A/V cabinets are a no go..

    PROS: Great value
    Excellent build quality
    can drive just about any load

    CONS: VERY HEAVY (Understandably so)
    No XLR connections
