I just finished assembling this amplifier, it went well but a few wire colors have changed in the new kit. It passed the startup "smoke test" and it has noticeably better sound then Yamaha receiver it replaced. Love that it does not have a fan. I think the kit from Ghentaudio is worth the money, well organized and nicely done. It would make things quicker if Quentaudio came with some basic instructions including a wiring diagram.
I was thinking about getting amp from Peachtree they use ice amps and I was interested in building one do you need a pre amp with that and he doesn't show where to solder I wish he showed more . How did you figure out how to wire it up ? Thanks
@@BostonMike68 No preamp needed, I have used a DAC or my Phone as an input. I had to watch the video several times to figure out the wiring, fairly simple in once you do it. I could send pictures of my finished amp just not sure how to get to you.
What a great video. I have Parkinson’s and I need to develop new skills to help my brain. In spite of the tremors I think I’m going to try this… Thank you so much for fascinating videos on a hobby I’ve enjoyed for almost 50 years (Hi-fi audio… Not building stuff!) Thanks again!
Ralph that's great to hear! Keep me updated and feel free to reach out if you need anything. Good luck! And thank you for the kind words.
123Toid I’m serious, you have a very sincere And informative delivery that I really enjoyed. Keep doing Just what you’re doing!
And so, did you build it?
maybe invite a friend for the difficult small parts
Hope you are still enjoying the Hi-Fi Ralph. I am an engineer of near enough your age and have worked in audio for most of that time. If you ever need any advice or help just drop me a line here (I will see it it).
De-pinning/re-pinning would be your friend in this instance. It would make wire matching a bit easier not to mention cleaner inside the case. Second, in the immortal words of AVE "Focus you Fak"
Today in this video, I'm going to show you how to build an amplifier. 75% of video out of focus.
It would be easy for Ghent just to make a wiring kit that already has these interconnects pre made, since they know they're going to be selling tons of these specifically for the 200ASC and 200AC modules. This way no soldering would be required at all.
@@Wizardofgosz But then folks that don't know what they are doing would get in over their head. Consider the soldering requirement to be a barrier to entry.
@@jameshisself9324 This build requires soldering either way.
@@Wizardofgosz Well then more or less soldering then.
Small problem. You're going from balanced XLR to unbalanced RCA. You cannot simply tie the + and - together as one lead with ground (or shield) and if you only use one side you're only getting half the signal. The only way to do this right is to use a matching transformer with one side having a center tap, which would connect to the XLR ground and the other side without the center tap going to the RCA. Not doing what I just explained will result in having to have a much hotter signal, which can create other problems. I've been to this rodeo with my PA equipment. Just passing on the tip
Great point
The one thing I would recommend with these units that use balanced xlr inputs is to ground pin 1 of the xlr to a case ground point as close to the xlr as possible, say one of the mounting screws for ex. And ground the shield coming from the board to a different point on the case. This reduces potential ground loop issues and the possibility of inducing noise into the signal chain, especially when using rca to xlr cables like the ones shown in this video. This also has been covered extensively in AES48 specs and documentation by hypex, Rane.
Hi which site do you recommend to purchase the balanced XLR inputs?
@@Steven-e7c The Ghent Audio case he is using in the video comes with xlr inputs. I believe they are Neutrik.
@@aredd92 thanks
I'm not sure if it will work with the power button setup you have, but I bought a Ghent case that uses an LED status indicator and a rear power toggle (no push button power switch), and I was able to configure it to automatically power on and off. Instead of using the mini jumper on J4 (power always on), I jumped J3 input 4 (signal sense) to input 8 (+ audio in) at the XLR connector solder tab, and the amp turns on and off automatically when it senses a signal from the DAC.
@@BuckStrickland-yc3czTo be fair these Amps are incredibly efficient and the standby power is minimal especially when compared to an A/B amplifier. I wonder what the real word energy savings are in your case?
I feel like ive just opened up my favorite new wormhole of sound possibility. Couldnt have made it look any easier!
its natural smooth and unintimidating sound very refreshing, actually rare in market full of ciems and headphones

Ive been wanting to make a good quality class D amplifier for a home subwoofer that had its board die, and i lost it before i could fix it. This would really help me set it back up and get it running without having some cheap homemade amplifier that barely outputs power. I didnt want to buy one, i want to expand my electronic skills and try to build one. You sir have made this possible. Thank you.
I'm one of those (super) snobby audiophiles (tubes, mono blocks, vinyl, TAS) who's been at it for twenty+ years and knows his music without using head cans. This dude's video just blew me away today!!! No link was listed for the XLR to RCA cables.
Thank you Vinnie. I am sorry about the link. I will update it now. For now, here it is for you: amzn.to/2Xdpqgv
@@Toid Danke
I tried to build a stereo amp with a toroidal and 2 tda boards. Never worked, just left it to gather dust :) this gave me the motivation to troubleshoot it.
Great to hear!
When i read "How to Make" i was kinda expecting to make it from skratch , but still a thumbs up, it was over all a good video even though it was different than i expected
Thank you. I appreciate hearing both comments!
Just built this amp. Thanks for the video! I wouldn’t have tried building it without your help. Now I need to build a Bottlehead preamp so I can try it out.
I built an 833A single ended triode amplifier at a fraction of a percent of the cost of the WAVAC $350,000 833A pair of monoblocks. It took many experiments to get it right but the sound is excelsior.
I just want to say as s subscriber from when you had only a couple thousand. Your editing and format has come a long way. Keep up the good work!!
Thank you. I have really been working on that. So I appreciate hearing that.
Please send it to Andrew Robinson for review against Crown XLS!
Crown is fine...
I'm curious I would like to hear your opinion of how this compares to other amps on the market.....to be more specific...things like quality differences, life span, and limitations.
Honestly, I have been ecstatic with the quality for performance. These are the only HiFi and I use now. in fact, I just built a smaller version of this for testing speakers. It should be on the channel soon.
Very good, i built this entirely from the links, parts and steps detailed in the video.
What would people recommend as a dual gang Potentiometer between the source eg: phone/dac/computer and the amplifier for volume control?
Was thinking something like an ALPS RK271 dual gang potentiometer 100Kohm, and a capacitor 40nf capacitor?
This video has convinced me to try to build one of these amps! Question...do you think building this amp would be easy enough for someone with only the use of one arm? (the other recovering from surgery)
Do you have any recommendations for an on board Bluetooth receiver board for this amp?
Oh man, what a great video. I did not even know you could build your own amp! I'm definitely going to have to delve into this as a new hobby. Thank you for the instructions!
You're welcome! Glad I could bring it to you.
You can definitely build your own amp and you can DIY way more than this. There's nothing wrong with this little set up but if you wanted to be nitpicky it's not really building your own amp but more like putting together all the main pieces of an amp. It's what a pre fab double wide is to actually building your own log cabin. An even more hands on approach would be to hand pick an amplifier chip from one of the manufacturers and then search out a board for it and personally select and order all your capacitors, resistors etc. Even more hands on would be to design your own discrete transistor amplifier and have your own pcb customade by a board house,. The possibilities are endless. One could spend their entire life dinking around with diy audio and not even scratch the surface of the possibilities
@@jethrohetero4990 You'd need knowledge in electrical engineering, I assume?
@@michaelhenry3234 not necessarily, I guess you could call it that but you don’t need to know the whole scope of electrical engineering. I mean if you were going to design your very own discrete design and pick all the transistors yes you would need to know quite a bit but there are lots of simple great sounding amp designs on the web that the amateur can build. There’s a quite famous one called the jlh 1969 amp that sounds fantastic the schematics are all over the internet There’s a bitching single mosfet amp Called “le monstre” designed by Jean Hiraga and there are also a ton of chips that only need some capacitors and resistors to make work. It’s great fun really if you like hobby electronics. You can etch your own PCB’s or order them from board houses for pretty cheap
Back when I was a tweaker I’d spend hours geeking out on honemade amps. Now that I’m sober I’ve been wanting to have another go at it and see just how impaired I really was. I bet i could whip one up in no time with nowhere as many mistakes as I used to make
Well, that's very much appreciated sir, thank you I'll have to look at video again not as familiar with being successfully hands on building or repairing amps, but I have had experience with diy speaker building since high school and I'm north of 40 now. I really enjoy things like this so thanx again keep it coming!👍🏾👍🏾
Your welcome Jeron! Have a Merry Christmas and Happy Holidays!
Toid do you recommend this over the fosi audio V3 ?
It all depends on what you’re using it for. The V3 is a really good amplifier and has a lot of power. But if you want high fidelity and have a really nice preamp, this would be the better choice. For most people, I would probably just recommend the V3 for their purpose.
Thank you for taking the time to build these amp. Don't have much experience with class d amps myself. I wish more videos of building amps existed. Have you considered trying to build a low powered class a amp? I purchased some of nelson pass diy amp camp amps (their are version 1.6 now). They put out 6 or so watts of hot class a from the single amp and more out of the new mono version (one for each channel). A little over $300 for each kit when they go on sale. They sell out fast each time at diy audio. These run on cheap switch mode laptop (24 volt) power supply and sound Fabulous! They will even sound better with a proper linear power supply. More $$$ to. Just keep in mind these amps need to be used with efficient speakers (90 db and up). Even better with higher efficiency speakers. Just a small taste of the that legendary nelson Pass (pass labs) sound for not spending thousands. And if your wanting even better amps and wanting to learn more their is the diy first watt f5, j2, etc that offer even more😀 thanks for sharing this build!
I'll have to take a look into that
@@Toid your welcome. I'm not sure which batch will be shipping out or when but I think you can given them email to notify you at diy audio when next batch is available for purchase. Just a heads up..each batch sells out fast. I have missed a couple not being fast enough lol. It would be terrific to see another video on assembling one of these kits. One video exists online of them putting together a older version of this kit together. Those were 2 little mono amps. Can't wait to put my amp camp amps together. Need to get time and a soldering iron😀
I wonder if it is not even cheaper to by a amplifier board like iraudamp7 or tpa3255 and get a regulated power supply like SMPS500R and buy a case and do the holes your self. But that is maybe another video. ;) I love your work!
The best modules for hifi use are the ASX models. The ASP uses 380kHz switching frequency, while the ASX uses 550kHz. The ASP is better suited for subwoofer speakers...
Why is that higher switching freq going to make it better?
What about THD or SINAD?
It's not just about watts, but how clean, linear, and without distortion or noise the signal is.
bit.ly/200asc all the information is there. There's a reason Hi-Fi manufacturers us used these boards.
I’m wondering if this is a better option than proven class D amplifiers like the Crown XLS series? I mean DIY is a win on this but bang for your money, what’s best?
I really love the crown xls amps
I just grabbed the crown and I love the extras you get with it for around the same price. You get crossovers leds ect ect
That's a very good question -- although Crown's customer base is mostly pro sound folks and DJs, AFAICT their amps are certainly well suited for home audio systems that need lots of beef to handle volume peaks too. Of course the "audiophile" crowd will dismiss the XLS amps as cheap Chinese-made junk, but I honestly wonder if they could tell the difference between an XLS and a PS Audio Stellar amp driving the same speakers at the same high volume.
Crowns have some what higer noise and distortion products, you can check ASR fórum for some nice measurements on some icepower based amps and at least one class d crown, i think it was a 2505 or some like that. Ice amps excede the total signal to noise by some 10 db diference aproximatly compared to crowns, true the second delivers More power per dollar spend
Also look at the 3e Audio 3255 board and matching power supply.. great class d chipset, v good sound and build quality.
I do have already 2 mono class d amps - 200 W each and indeed they sound good. Not lce though.
That's true, ICEpower is amazing lots of my bang&olufsen products use it. But standard class d is also really good
How do you adjust the volume?
This just powers speakers. You need a preamp (or integrated with pre outs) A preamp takes in all sources i.e. bluetooth, phono, cd, etc and outputs them thru this amp while also controlling volume
I’ve seen these modules in the parts express catalog. Always found the prospect a little daunting. This video will certainly help the novice sort out what he needs to get started. While I have some amps I’m very happy with (NuForce Ref 9SEs), I’m tempted to build one of these as a back up. Nice job, buds!
Thangs AJ. I'm glad to hear that.
It would be possible to control the volume of the amplifier?
Awesome, much appreciated. Making me feel like I can properly build this type of stuff!
GREAT video, thanks!! now...ahemmm...how does one add a RADIO RECEIVER to this? Maybe, even, a DIGITAL RADIO RECEIVER!!! (my local NPR-station only plays Classical that way. Ugh) tanx!!
Hi, looks like the Icepower 326-210 is not available on parts express. Do you know where I can get one or is there something else I can use? Thanks in advance.
Oh, this is tempting!
Can you made 2 ohms stable hifi amp for DIY 1 and 2 ohms hifi speakers?
Could you please make an AV receiver? Maybe 8 or more channels, with 2 or more subwoofer outs😊😊
Very nice job i have been in electronics for ever had repair shop25 plus years,never new these boards were around.Audio is some thing I spend time with everyday quality is a must i heard you mention big names at start of video using same boards have you done output watts,ohms,thd, testing and compared to the others I think u said rotel or something same quality if so how did they compare to each other and if you remember the values would be awesome to know. What you did in here was very cool and I learned something which is the best any more u can do will also be appreciated much good guy keep doing the same!
Robert most of the data these big name companies rely on come directly from ICEPOWER. They all lick abs choose what they want to publish. All the data you could want is indeed their spec sheets found in the description. If you want a decent idea of each manipulates the data, this is a good article on it: www.audioholics.com/audio-amplifier/clone-amplifiers
Very cool, and informative video! Thank you for the enlightenment.
Great Job. Always wondered how you could build one. Seemed like parts express was missing some stuff.
Yeah, it is awesome that they finally started carrying this. I was really excited when i saw it.
Great video and very encouraging. However, I would like to have seen a readout showing its frequency response, and a comparison with a branded, $3,000 amplifier. Also a sound demo would be useful even taking into account the limitations of UA-cam sound.
Thank you for the awesome videos. Is the wiring the same on the 1000 amp model? Is a low pass filter needed to run a sub if my signal is coming from the sub output of my denon home receiver?
Coming from the car audio world, I don't see how to match the input gain of this amp to the source. Is home audio amps all standard 2.0V max or can I just use the output from my Denon home theater LFE output direct to this amp and use the Denon gain in the settings to match? Thanks for the video and help!
Any chance of using a generic Bluetooth board in this setup?
can you use these as mono blocks and how many watts per channel is the output
You can. You can get modules that will output 200w, 500w and 1000w respectively. The links are in the description of the video.
What about if you wanted a full stereo system. It would include 2 bookshelf speakers a middle channel and a sub. How much and how big would it need to be.
Thank you for this video...I would like to confirm (I've scrolled through the comments and think I saw the answer, but....) - assembled as shown you end up with a stereo amp putting out 200 wpc into 2 channels, at 4ohms...correct?
You're welcome. And that is correct.
What makes you think this is equivalent to a $3,000 amplifier?
These are the exact modules used by the companies he mentioned in the beginning of the video. They just put them in their own cases and charge like 3 grand.
Jack Allen that is not entirely true
Please state what IS entirely true.
Omg so confusing
This is not really exactly the same as a PS Audio Stellar series amp (not sure about other amps they produce), as they use proprietary input modules and different ICE amplifier boards, BUT this is probably a terrific amp for a great price, and I appreciate the video. By all accounts ICE power amplifiers are very good sounding amps. I may build one of these as a project this year. Thanks for the awesome video @Toid123
Can I plug a DAC like the Schiit Modi 3 directly into this amp? Or will I need to run it thru a Pre amp? What are options for powered sub connections?
i found a used diy poweramp with a design like this a year ago, dual 200 asc for 2x100watt stereo in 8 ohm typical.
im still learning about what i actually got, it runs cool and silent and sounds good. hopefully i can find more reviews comparing those amp boards to other prebuilt brand poweramp counterparts.
only gripe i had was the auto power on sense was turin off my amp at low volume after less than a minute. but i got around that with opening up the case and bridging 2 pins so it was always on. with diy amp boards you can get proper schematics online so i could figure it out, much harder if i had a brand name poweramp.
The ground/earth connection with this particular amplifier case had the paint stripped but be sure the area is clean for a metal to metal contact if you're using a different enclosure. If you have to, use sand paper and clean the area to keep the project safe. (Having a bad ground can also cause noise in your speakers when nothing is playing)
Actually it came all scrapped off down to hate metal. But great point.
@@Toid Ah okay it looked painted but you had it in your hands and I'm watching from home. Probably still worth the comment to those who may use a different enclosure I guess.. Liked the video though, I'm sure you helped some people out who wanted to get some good sound without breaking the bank and you really didn't miss a beat when it came to assembly and explaining the steps. Keep it up man!
@@Koroyanis thanks man. I appreciate hearing that. Thanks for the great comment and thinking about others.
So the Ghent audio case doesn't have a 2nd LED for standby mode?
Also, what IS standby mode? If it doesn't detect input signal for a few mins it powers down?
What is that auto off jumper that you installed on header 4 actually doing? (the cable you got from Parts Express?)
What happens if you don't install that jumper?
What is hi Fi, do you use this with a receiver
Hello. Graat video.
A question: i have 200 AC module and the 200 asc is disontinued. The 200asc can be replaced exactly by the 200AS1?
Thank you
I'm a lil lost. One is the amp and what's the other bord ? Is it another amp ? I checked the amp board on p.e. and it's one out put for speaker. Do you need 2 amp boards ?
The links to the boards are in the description. One of them includes the power supply as well as one output. The other board connects to that for power and just has an output.
@@Toid thank you sir
Why would class D combine with a smps considered as hifi? by spec I prefered class A with linear supply considered as hifi
Question about this RCA to XLR connectors. Are those just sending Pin 2 to the Tip of the RCA, and Pin 1 to the sleeve and ignoring pin 3, or are they sending Pin 2 to the tip, and combining pins 1+3 and sending that to the sleeve of the RCA?
(ignore this, Amazon answered that for me)
i look at the 2 boards.. it says "1x200W" but the amplifier you build is stereo,, what am i missing? and dual mono blok? i am confused.
Hi. I have a home-built stereo Wadar amp using tubes and that sounds great too!
Nice!
how to make your own.... oh wait you just buy a kit with all the components already soldered. Thought you were going to design an amp lol
You want him to buy a lithography machine as well to make the chips for the board? Lol. Get real.
Add Parasound 2350 but some ICE modules are not sold to the public. Also Pascal modules, also made in Norway but I don't know where you can buy Pascal.
What PC boards would you use for a 12 volt car audio amplifier?
How is this amp with the small Magnipan speakers and a tube pre-amp?
You can get boards such as the Gainclone from elsewhere FYI.
Besides te difference in power (200Wx2 Vs. 125Wx2) would there be any relevant difference i the pre-assembled amps sold on e-bay an ali express that are based on the ICE125ASX2? I ask because my budget is very limited and I would like to use the remaining on an also budget tube preamp.
Yes. I'm fact someone on the forum bought one of those and found out very quickly that it was a knock off. Most of the boards that you find on AliExpress and eBay are not genuine ice power boards and used inferior parts. He ended up having a major audible issues with his. It's best to buy from a reputable company that you know is selling the actual unit. Parts Express does sell those, if you check the link in the description it should link to it. I have one that I'm currently using for testing speakers.
@@Toid thanks s much for tge quick reply, I'll stay away from those for sure. On the other hand, have you found any less expensive cases someplace else? Purchasing a cas that's worth almost the same as the boards seem a little high. RCA imputs would also be nice.
@@leoher5338 I haven't really looked. But really any case that fits it would work just fine. Assuming that you don't mind pre-drilling the holes. It is a pretty popular board, so I bet you you could find a case on AliExpress or ebay that does fit it that might even have the holes already drilled. I just have never looked.
Hi. Can a Bluetooth board be added to that amp? Thanks.
The only thing I don't like is how pricey the case is.
what type of preamp would be best to pair with this for volume control and other functions?
You don't need a pre-amp for volume control, a dual gang 50k log pot will do - try to avoid carbon ones.
$300 for a supposed 400 watt class D amp that you have to assemble yourself is kind of high. I haven't heard any class D's that sound good enough to consider replacing a good class AB
and Class A typically shits on class AB I might add. Sure, class AB is more efficient, and runs cooler, but that's about it imho. I also prefer SET to PP designs too - the crossover distortion on the sine wave cycle on PP designs is nasty imho.
There are well designed Class-D amps that are astonishing. Do your homework.
@butchtropic Some people hear crossover distortion in PP designs (AB doesn't have to be PP, it can be done SE, but is a lot harder to design a stable circuit to do so).
AB is convenient - lots of power, low heat, good efficiency, and what appears to be good specs.
There is more to life than "specs".
@butchtropic PS I forgot to say that wattage is a pissing contest much like mp in DSLRs - 20w is perfectly fine for volume in small to large rooms that 99.9999999999% of people own and use. 200w etc is vast overkill.
edit: quality over quantity.
@butchtropic true, but that's where intelligent amp/speaker matching comes into play, doesn't it? Anyway, amp + speakers is 10% of the sound, the rest is your listening room.
What is the wattage and THD on this? Great Video
I don't know watt. Probably enough. All amplifiers have negligible THD. Also, you don't get meaningful information from THD at 1kHz. All amplifiers measure extremely well at 1kHz. Linear distortion tend to increase with frequency. Those who don't tend to be expensive. IMD is a much bigger issue. Here's a $6000 amp that measures well in some areas and bad in others: www.stereophile.com/content/ayre-acoustics-ex-8-integrated-hub-integrated-amplifier-measurements
This one for $55,000 measures better, though I'm less impressed by the THD vs frequency: www.stereophile.com/content/constellation-performance-centaur-ii-500-power-amplifier-measurements
Please don't use that shallow deep of field, it's annoying if you don't focus well.. It's more work for you and a distraction for the viewer and it doesn't worth it.
It is difficult to avoid that with a large camera. He need to use a flagship smartphone, they shoot video decently.
The shallow depth of field is simply because this guy knows as much about photography as he knows about HiFi.
Would be cool to do a diy IcePower 700AS1 subwoofer amplifier with volume, crossover, and phase switch
How would you change the volume on this amplifier? Is it just volume from the chosen source? I am interested on this project and maybe using it in a diy integrated amplifier. or even supplying audio to it from a raspberry pi setup.
Your preamp will regulate the volume. So whatever your source is. a lot of people hook this up till like a home theater receiver that has 5.1 channel out. In that case then the surround sound receiver would control the volume. But whatever source you want to use can control volume
Do I need a receiver that has pre outs for this? Currently have a Denon AVR-S750H (the one that just came out with 8k/hdmi 2.1) and want to build the cinema 6s but if the receiver can only send 75w to each channel then those will be severely underpowered since the horn driver is 60w rms and each of the subs are 130w.
The good thing about the cinema 6 is that it is very sensitive. So you really don't need much power at all. They would run off that receiver with absolutely no issues. Now if you wanted something better, it would need to have RCA preouts.
@@Toid good to know, thank you!
@@tmorrissey96 you're welcome
Thanks for the video however that lack of focus on most pcb shots was mildly infuriating. A slightly wider shot with deeper depth of field would help your videos tremendously.
Great video! will this work on uk voltage? 230v
This is a good video but the easy way out next to buying a ready made amp. I on the other hand mine my metals create my plastic parts create my chips etc etc.
ya ok, and yer end result would be below fisher price standard no doubt lol. but hey if it sounds good to you.....
I really love the look of it.
You always have the best comments! I appreciate it Jason
@@Toid your welcome. Keep up the good work. You Deserve more credit for these great Videos. Very informative. I see a lot of people in the comments getting angry because you said you own opinions.
I am missing something here, great video by the way. Are you using the 200asc board purely for power then, then connecting the two other amps to create stereo and therefore buy passing the 200asc's amplifier stage? Sorry for being naive but isn't there a product with just the supply and wouldn't it be cheaper?
The 200asc has a built-in power supply. That power supply powers the 200asc and up to two additional 200ac boards for a the channel amplifier. For a two-channel you only need the 200asc and the 200ac. It does not bypass the amplifier stage.
@@Toid ok, thanks for answering. New subscriber en route.
Hello,
Thank you for the tutorial. I put together the amplifier but I have an issue. I am using it with 91 dB sensitive speakers and a Schiit Freya preamplifier. The volume on the Freya has to be at least half way (12 o’clock) before I can start heating any sound.
Is that normal? I thought with me speakers I would have enough headroom...
I don't have experience with your exact setup, but that does not sound normal.
123Toid tried it with a different preamp and getting the same issue.
I am pretty sure I wired the power amp right otherwise there would not be any sound coming out of it.
A defective asc module maybe? But what are the odds of both modules being defective!
Any thoughts?
Thank you.
123Toid I switched the wires on the wire plug (live and neutral) and it made a difference. Now at half way or 2 o’clock is a very comfortable listening level. Much better than before!
@@mosobouc awesome! Glad you figured it out!
Is it class D or AB?
Can anyone point me toward an enclosure that is appropriate for three channels? I'd like to do a 200ASC with two 200AC to take care of my entire front sound stage. Bonus points: how can we make it work with a 12 volt trigger to turn it on? Thanks!
Contact Ghent. I believe he has some that will work with that setup. Just let him know what you're doing
You are still going to need some sort of preamp for volume control, correct?
Yes. For me, I use my Marantz home theater receiver.
I would take the Hypex Ncore version. It equals even a better than € 3000 version!
one more real problem I have, while the amp is dead quiet when its not connected, the gain and possibly the input impedance too high for my setup,
once connected I get hum and 2nd harmonic(120hz),
I ordered -20db xlr inline ettenuators, perhaps that will help, ( it replaces a hafler and crown amps with balanced inputs, that never exhibited any hum),
lifting ground had no effect.
It sounds like you may have run your lines across the power. Check to make sure your lines aren't run across or underneath the board
@@Toid -20db inline attenuators arrived today, all noise gone :-). (also should be 600 Ohms impedance now )
Is this the new circuit design aka d3? Advertised by new pioneer receivers or the circa 2005 designed ice amp. The later was not 4ohm tolerant. Did they publish a full bandwidth test at 4ohms. I only see a 1k sweep in the specs.
They did do a full sweep at 4 ohms. Which is nice, since a lot of manufacturers don't give that number out. You can find it linked in the description. Just click on the 200asc and then check out the spec sheet. They actually performed the most rigorous tests you can do on an amplifier.
Thanks!
Thank you!
Thank for share man
You're welcome!
Does anyone know if there’s a place on the boards for crossover frequency, bass level and phase control so I can build some potentiometers into it?
And if you go to AliXpress instead of PartsXpress, you can do it for $50
Did you find this board there?
@@hugopalmava He is just talking about class D board. I am guessing, he doesn't realize that icePower is a lot different than the run of the mil class D amplifier. Ice, has put a lot of work into their filter, so they can provide a high fidelity signal, that most other class D amplifiers can. The two most used by HiFi companies are HyperX and IcePower.
what comparison do you have to this amP?
Is it just a power amplifier or does it include a preamp too ? I didn't catch this detail...
It's a power amplifier without a preamp. You can easily use a surround receiver with a RCA preout
@@Toid that's what I thought, thank you for your answer 😉
Everytime I click on those bitly links, it just flashes - closes itself automatically. Hopefully no viruses there ://
If I want to just build this amp in mono mode do I need the additional module
Thank you sir
hmm cool i wonder what you use as a preamp
I'm using this in a surround sound setup. So I'm using my Marantz receiver as the preamp.
in the real hifi not exist absolutely smd elecronics component, this is a mediocre consumer amp
i know class D amps are efficient but ZERO heatsinks ??? for 200W of power ?
I've got a McIntosh MA 9100 Integrated Amp with 70W/channel at 4 ohms., that I bought new around 1977-78, and a few months ago it started shutting off the output at around 11:30 on the volume dial. At 10-10:30 it was fine, but if you pushed it a little harder, it shut down from the protection circuit. I'm looking at taking it to a Service Center to repair it, and the diagnosis fee is $80, which is reasonable and is applied to any work done, but if I can build this for $300 it may be better to use this as my power supply. The MC has RCA input jacks for supplemental power supply. So am I correct that I could use the DLR outputs converted to RCA from this unit into the MC, and then connect the speaker wires to this amp--or do I just leave them wired to the MC? Would this work? It would probably be less expensive to do this than fix the MC. Thoughts?
Sorry my MC is a MA 6100 not 9100 and its 60W/channel in 4 Ohms, but 70 in 8 ohms.
How does this sound, and compared to what? There is a lot of noise in this comment section, as with anything "audio", but what is the experience using this amp, and in what tradition is the sound described?
