Is this the Most POWERFUL Amplifier for DIY? It seems like DIY amplifiers are continuing to get better and better everyday. Almost all of them have bluetooth 5.0, aux in and the works. But only a few amplifier are powerful enough to transform into an amplifier that works for your project. Want a 2.1 amplifier? No problem! Want to design a two way bookshelf speaker set without any physical crossover components? No problem again! This amplifier might just be able to do it all. In fact, it might change how you build and design speakers.THis is why it might just be the most powerful amplifier for DIY.

Quick tip for those of us elsewhere in the world. The sure/wondom boards are the same things and are generally cheaper. Dayton is a rebrand. Thanks for bringing these boards to everyone's attention Nick! Hopefully it ups the quality of everyone's DIY builds!
Thanks for the tip. But are they actually identical? Dayton Audio claims a minimum inpedance of 4 ohm while sure states a 6 ohm minimum. But both of them measured their specifications with a 6 ohm load. Since 6 ohm drivers are not as widely available as 4 or 8 ohm ones it would be good to know if the Dayton Audio one can actually do 4 ohm load or on the other hand the Sure one is also capable of driving 4 ohm loads. I couldnt find out what chips thtey use or if they are identical.
Edit: I actually found a site that sells them under the Wondom name. I'm pretty sure they are Sure ones just rebranded. They state its a TDA749X Chip, but not which one. They also claim an impedance of 4-8 ohm the left and right channel outputs and a minimum 6 ohm impedance for the bridged outputs.
@@baluuu2 Yep, the ones with the same power ratings use the same chips. The only difference I can see for the different ratings would be different output inductors. When inductors with values designed for use with 8ohms are used, when 4 ohm loads are used instead, you get an earlier high frequency roll off, I imagine it'll be that. But honestly, wouldn't be surprised if Dayton named the 6ohm boards as being rated for 4 ohms even if they aren't, especially since the descrepencies from inductor choice wouldn't be noticed by your average customer.
@@baluuu2 Also, Wondom is Sure (it's their consumer audio division), the Dayton's are relabeled Sure/Wondom boards, not saying there's anything wrong with that at all. Since it's not a copy/fake, just a rebrand.
In Germany the price gap is crazy: 75€ Wondom, 120€ Dayton Audio.
@@lennarth.3383 I live in Germany as well. The Dayton Audio version is sold out at Soundimports. But since they are pretty much exactly the same there is no reason not to go for the Wondom board because its 45€ less. @Elliott Dyson It seems like they are the exact same board. They spec sheets are exactly identical apart from the minimum load rating. But another german distributor that sells the Wondom boards states that its 4-8 Ohm for stereo and 6 Ohm for when you bridge the output. It would be nice to know if they are actually able to handle a 4 Ohm load or not. 6 Ohm drivers are hard to come by. And with an 8 Ohm load they can "only" output about 80 watts. After some research i am pretty sure they both use TDA 7498 chips from ST Electronics.
DSP is now so powerful, accessible and affordable that it should be a no brainer for DIYers. DSP active multiamping makes high end pro audio performance available to the masses.... provided one is willing and able to learn how to use it to best effect. I'm using it to achieve the best sound quality I've ever experienced or even thought possible, from very affordable drivers.
This will be mind blowing for DML speakers!
@@yiravarga yes it would be!
This is a dope amp for diy guys it takes the headache and skill out of designing passive crossovers and gives you a ton of flexibility. Great video as always Nick
Hi!!! I'm diy user and a follower of this channel is a very helpful board for new user's and for my diy home system thank you!!!✌️
Thanks Nick. Great stuff!
This is really cool. Been literally waiting for someone to make video on this board. You definitely got to make a 2.1 or 4 way speaker project using these. Like the your boombox project. Considering this outputs 400 watts, it should be a super powerful system.
Just an FYI if you are still even interested. I did some shopping around and found out that if you want to stay within Recommended Power Input you can get around 380 watts safely. 38v @ 10amps. Power supplies being what they are, I would not recommend going to 39v @ 10 amps or exceeding the 10 amp draw. Even then, having 95watts per channel is pretty nice.
I’ve been looking at this board and i’ve read a number of reviews saying that they fail fairly often. I’ve seen several restocks/returns of this unit so I have not pulled the trigger.
I built a few “boom boxes” with the shure chip amps and they have huge power when you give them the proper power supply or battery pack.
The dsp options with this unit are impressive, I hope Dayton will continue developing more of these boards, maybe a dedicated wireless lfe channel that’s 2 ohm stable?
Thanks for the video!
I just received mine. Can't wait to try it.
Looks great, thanks! So many applications for this. I was just braingineering a passive/active (Bluetooth possibly) speaker with a full range driver.
I have to try one of these.
I’m a broke college student and I have a CNC and I’m going to make the ultimate party boom box using FaitalPRO 8FE200 8” woofers, morel CAT 378 horn tweeters, and a Dayton ultimax 8. I just finished the design and have to touch it up tomorrow and hopefully I can start machining next week.
I’m using two 36v 10a power supplies for two KAB 4100 boards.
Each woofer and tweeter gets its own DSP and amp channel, and the sub will get an entire board running in dual bridged mode for 400w total. Already with 50w on the faitals they show 110db on WinISD. This is going to be nuts 🥜. My simulations show the sub can hit 112db at 40hz which is perfect. Can’t wait. Just bought everything today.
I was thinking about making a CZcams video about it but I’m not sure where to start.
Excellent video
This is amazing
Thanks for the info. I saw these at PE (sold out...) I've been looking to make an active 3 way studio monitor type speaker.
Man you are on FIRE!
Getting a few boards to check out quality and distortion for my soundbars and powerful boomboxes
Great video!
That's Philip! Now I need to get a project or two done with it
I’ve been obsessed with the idea of making my own speakers for yearrrrs. Have watched countless videos about building them. But the thing is, the more I watch, the more it seems to become a very daunting undertaking, it seems like as soon as I think I have a good understanding, then then some new person peels back another layer that’s even more complex and nuanced. Used to think eh I can just slap some plywood together cut a whole and stick a speaker in. Now obviously I’m embarrassed to ever even let that cross my mind lol but I also now feel intimidated by the project I want to do because I know when I get it done, using all the knowledge I have. I’m going to end up seeing a video that’s similar to my project and mines going to be trash in comparison. And I’ll feel like I’ve wasted my time… however, I’ve been watching more of your videos recently and they’re giving me a lot of insight and motivation to just say fuck it and do it. I’m just going to start with some small computer speakers and see how it goes. Great content btw lol
That is awesome! You should document your work on the forum. We’d be happy to help along the way if we can. Www.toidsdiyaudio.com
Nah - it's not that hard. There's tons of tried and tested kits out there, open source, flatpack ready cut boxes - the best bit is finding out what does actually make a difference you can hear.
Don't ever give up before you try something and I can tell you from experience you'll get hooked on trying to constantly upgrade it lol it's a good habit to get into I started as a kid and now im getting into actually making,y own voice coils among other things using the wires from old DC motors so go for it man you won't regret it@@sjbechet1111
How about a 3 way open baffle source aray n xtreme Dany Richie style??? 8 x woofers , 2x full range and a plannar magnetic speaker on a wave guide
Hey Nick, is it possible to replace the circular potentiometer for controls with a slide potentiometer from digikey?
How does this amp sound?
Is it just something easy to play with or does it deliver a nice amplification like bigger amps?
Thanks a lot!
My plan is to link two of these boards and use one each for a three way cabinet and a subwoofer. One channel for the midbass and one channel shared by the mid and tweeter, two channels bridged for the satellite Sub. So a 2.2 using two amps. Very close now to pulling the trigger. Probably a Christmas/Birthday gift to myself.
That is going to be a very nice birthday/Christmas gift! Looking forward to seeing it
@@Toid Thanks, I like your channel and had a look at your forums yesterday. I will try and take some photos along the way. Thanks for your interest.
Man that shit looks damn sweet
Great coverage of the main aspects of the board what about this 8 channel talk in the text of the description? :)
Can I hook up all 4 channels (2 bridged channels) to the same voice coil for a subwoofer? I’d like to use it ti power a 8” ultimax subwoofer.
Do you need a Preamp with these boards?
Also could i use this board to make a 3 way mono? 1 channel for high, 1 for mid, then the last 2 channels bridged for bass.
You cannot do everything with active filters. Impedance linearization (Zobels), null-filters and reduction of resonance frequencies comes to mind. But you can mix the two.
I haven't looked at these since the first version, the amps were the drawback for me... noisy, hopefully they've improved. I'll have to check it out again.
5:43 is it possible to build 1-band PEQ with this thing? Can you control gain, frequency and Q in realtime with 3 potentiometers? I tried chinese wondom audio thing (also sigma studio) but it seemed to impossible. I managed only to make predefined number of curves, not a parametric solution.
Can you do a DIY KEF LS50 Wireless II clone?
Hi,
I have the KABD 4x100 and I'm driving 4 store-bought speakers. How can I control fade/balance? I have ordered a KPX. Would like to fine-tune the sound. Any instructional videos you can point me to? Thanks
How do these Dayton dsp boards compare to the ones from miniDSP?
The bottom line does it sounds any good compared to others ie separate components, e.g. Minidsp and Class AB Amps Combo. Difficult to get a digital(Class D) amp to sound good at such a cheap price.
I have the Wondom version and it’s very powerful both in terms of the DSP and output. It is however quite noises. My project used pro drivers with high efficiency (94db+) and I could clearly hear a hiss from the board. There is now a new 4 x 30w version which I’m anxious to try as the 4 x 100w is actually too much for most of my projects.
Yeah, that is a downside of these boards. Pretty poor SNR, not sure whether it's the amplification stage or the DSP stage, but likelihood is it's a bit of both
I've used the 4x100 and 4x30 and can say that the 4x30 seems to produce signficantly less noise. It's a great board if you're using high efficiency drivers and don't need to fill a massive space with sound. I'm using the 4x30 to power some floor standing speakers that use a Dayton PS220 full range driver and a Peerless subwoofer in each, and this little amp gets way louder than would ever be comfortable to listen to in my living room. I've got the 2x30 in a bluetooth speaker build and have another one in the works too
I don't have that issue with Wondom/Sure T-amp, so it could be related to the cheap DSP.
One issue I do have, though, is that it generates quite a lot of heat at idle (I have two boards bought at different times from different sources and it's the same on both), and requires the fan to spin-up every now and then - even when nothing is playing, which is weird and annoying.
I see an active cooling here, too, and it's obviously designed by wondom/Sure, too - does it have the same issue?
@@tomkocur yes the Dayton version of the 4x100 gets hot and needs to spin up the fan occasionally when idle.
@@joewilson4436the same thing happens with the Wondom version. If you use a 24v 350w PSU, you will resolve that issue, but get less power output.
I always had a question about these boards. How can I use these for speakers i am trying to build with some off the shelf amps like XA25 or JC-5 etc. I would not want to replace those fancy amps with the amps in these. When I use passive XOs I can use those between the amps and the speaker. But with DSP type XOs do I need to get these fancy amps for each channel or are there DSP boards that take speaker level input like passive XOs ?
So what about the bluetooth? Can I control my eq over bluetooth? How does it pair? Can you plug in a display? Also how do you power this unit.
What is the best you can get out of a 8 ohm subwoofer( max 1% thd )
Great video on the intro of this great amps with dsp. This is what MiniDSP should had done long back. Wondering how we can use this as a solution for the car with just a head unit. Use these as dsp and power our speakers
That's actually one thing that I'm thinking about as well. The DSP is so powerful in this unit, it would be excellent for something like that. I have a pickup truck that I'm redoing that I thought this would be interesting to try on. I'm just not sure how much power I'd really get from it. They used to sell just the DSP board by itself you can hook up into your own amplifier. I kind of wish they would come back with something like that again.
They make a stand-alone dsp as well that you can run in-line with car amplifiers. I believe that is powered by 12v . The amps are 24v I believe so they will not work in a car without a transformer. I think the model number for the dsp is the dspb but it’s all a little hazy
@@FungiFrenzied they do offer the older DSPB boards still. They just don't offer anything new in this line. And you're right those could be an option. As far as these amplifiers go, this one works anywhere from 12 volts to 39 volts. It could work for a car. But you're probably right, the older boards without an amplifier might be the better route to go.
@@Toid these can be daisy-chained with one acting as a slave so you could use two of them if you need more power - assuming that makes sense with your driver configuration of course
Would love to see a full 3 way active tower done using these guys!
That would be a good video, but would they need 6 outputs? This board only has 4. Or maybe use 6 boards?
I did a 3 way large bookshelf with 2 of the 4×100 boards. It kicks ass
@@blakebrockhaus347 that would be cool to see. Do the left and right bookshelves need to know about each other (timing/phasing etc), or does it work fine with two independent amps with one line level input each?
@@dcuccia the two amps are linked together, but there's nothing to do with phasing since it's one amp per speaker. If you go back a little ways on the DD audio Instagram you can find a vid where I talk Abt the build
@@blakebrockhaus347can you point me in the right direction for cascading schematics, specifically how to power two of them
Damn, I never saw that Dina boom box you made. I built one about 4 years ago like that but I used Dayton tweeters as well. Can't remember the part number. I used the old KAB boards. 100 watt with DSP and the 2X50 with bluetooth. Used a passive crossover between the mid and tweeters. It sounds really amazing. My only problem with it is, that Tang Band has a ton of distortion. I am looking at that new Dayton 5.5 carbon fiber driver. The one that has crazy XMAX to replace it.
ND20FB was the tweeter crossed at 4k. These tweeters are worth their weight in gold. I use them in every small project. Just amazing!
The Tangband have 9.5 mm Xmax, or the woofer is broken or it has to do with no highpass on the woofer
Hi whats the real rms power per channel & amperage compsumtion on 12v battery
What a perfect example of that technology brings democracy to more people!
Can I build a cornwall or heresy using this system?
can you build and make plans with this , for a super duper boooom box please
A ps audio fr30 clone would be a pretty interesting project since parts express Carries similar drivers to the planars they use
At that price point they're definitely using custom drivers. Ps audio has actually shown the development of their drivers over time, so you wouldn't be able to build the same speaker. Maybe something similar tho.
@@blakebrockhaus347 interestingly enough, their speaker uses a midrange and tweeter that is very similar to the old BG Neo planar drivers. There are actually some drivers that are available on parts express from GRS that are similar. The reviews are somewhat mixed, but I bet you could pull off some decent results with them. Their woofers are really custom tho, dunno how you'd clone that.
@@blakebrockhaus347, You'd be surprised according to many forums they are actually using a variation of the BG Neo 10 drivers and Neo 3 tweeters. In fact, some DIY hobbyists contacted paul and asked if he would do a production run of the drivers for the public, but he responded that it wouldn't be worth the time or money to do. Those woofers are definitely custom tho, they brag about that a ton on their website.
Waiting for a TPA3255 version.
This is a great video. I'm a woodworker and really just getting into this. I just ordered a KABD-230 mostly because of the great sale price. But I don't understand something...If you only have two channels and two full range drivers, what good is DSP? (if this sound ignorant its only because I am).
You can level and balance the total output. This can balance a terrible box design and / or room interference.
Muy buen video 👏🏻👏🏻👏🏻
Quiero hacer 8 bocinas activas que funcionen con un power bank y conectadas por pares en estéreo y mandar la música desde mi IPhone, para el n jardín de fiestas donde la gente disfrute de la música en estéreo, no quiero esos parlantes potentes que tocan en mono y la música la vomitas, este amplificador me puede servir ? Que más necesito? Me puedes ayudar 🙏🏻🙏🏻🙏🏻
@Toid Can the gain of specific speakers be turned down? For example to minimize noise coming from the tweeter (as some people report the boards to be noisy)?
from what I understand yeah you can attenuate any part of the band you wish.
Hi there, could I theoretically take the crossover out of a preexisting set of speakers and use this to practice on?
Absolutely. That is a great idea.
hello sir , you sound system audio quality I like it a lot, it's exactly this quality of sound that I'm trying to have in my car .
you can help me to see clearly what I should do?
I'm on an Audi A3 8L, I installed rnse from A4,when I tried the golf 6 rns510 radio, the whole problem was solved, the sound quality is very good, the sound quality is super clear and the bass quality is pleasant .but not possible to fit a radio in my central console.
I equipped it with the bose system ( basically it's 2 hp in 10cm at the front at the doors and tweeter +10cm at the rear panel + sub unit with 2hp disappointed. )
I'm looking for sound clarity like the 2010 cars the sub have 80hz , so I changed the front hp to the a8 hp and the rear to the 16cm hp, the sound has become different, but not better, I removed the original sub box, replaced it with a wheel sub box, that removed the 60hz and added 30hz its good bass ,but not good sound but does not make you want to listen to music. I look for 80hz bass. I think the sound filter of the 2001 and 2010 radio sound different, you either have to modify the radio filter , or need filters between the radio and the amp, but my level does not allow me to filter this her
What I cannot find is a demo program for active three way speakers with one of these in each box. Is there such a thing available?
Check the link in the description, it's in the download section
Is it possible to chain three of these 4-channel boards together to create a 7.1.4 surround sound receiver?
You can cascade with another to build audio 8.0 or other systems
I bought this amp too, but the fan isn't on. Does somebody know if it goes on only when it gets warm, or should it be on all the time?
it should turn on only when it gets hot
can this be used in someway or configured on a 1 inch tweeter / 2.5inch mid and 2x 5.5 inch subs in each cabinet? or would I then be more easy if you did a 2 way coax tweeter / mid combo unit and 2x 5.5 subs ?
Well you didnt specify the actual power output of each driver. You could, say, put the tweeter and mid on one channel sharing around 100 watts. You could then put the subs on the other two channels for 100w each. So what Im sayin is one Cab - Tweeter/Mid/Sub with two Channels and the other Cab same same with two channels. its a four channel Amp. I would definitely get the best brick for power.
I’m wanting to cascade two of these boards to create 3 way speaker system but can’t find anything referencing the power requirements for two of these together, anyone point me in the right direction?
I am thinking the same thing but yeah if you want the same output per channel you will definitely need two bricks. One brick for each amp if you want the same output. One brick if you want half the output. Not even sure if that would work. I dont thinkn you could carry all that power on those thin bridge wires to the second amp and all the rest of that particular circuit would have to handle the power. Pretty sure you will need two bricks sir.
These are so cool! I don't know why we don't see more of these in use? They're so versatile. I would really like to see you use one of the MiniDSP amps to build a speaker with. Those are like a higher end version of these. They're not technically high end, but a rung above these. Pretty sure they use the Ice Power modules in them to give you an idea. Thanks for the great video. ✌️
guys still cant wrap their audio heads around using the software on their laptop or pc or even their phone. There is a threshold of understanding that needs to be observed but once it soaks in you will wonder why you didnt do it years ago.
@@halrichard1969 I suppose that's a big part of it. I'm a computer geek from way back though. So it's natural for me. And it's the way everything is going. And I'll be damned if I'll be left behind. I see that as a fool's errand myself. ✌️
@@amb3cog I think you have the right point of view. I was looking at these amps a year ago and after five minutes of study on them My eyes walked away. But now for some reason it all clicked after a couple videos and searching around for a cheap amp that could do it all. I feel really good about getting it done. I already calculated out the speakers and Boxes on WinISP. Its a fun little program and free. I grew up in my Dad's Garage. I got tools coming out my ears. And i know how to use them. Today I studied up on connectors I might use and decided on XLR 6 pin jobs. for the Monitors since they are three-way speakers. One channel for the Midrange and Tweeter and one channel for Mid Bass Woofer. Two channels bridged for the Satelite Sub. Just multiply times two and that will be my set-up. A 2.2 system, one amp for the right and one amp for the left. This will most likely be my Christmas/Birthday gift to me in another month or so. Thanks for the Interest.
@@halrichard1969 Sounds great. I've heard people say that the best speakers you'll ever own are the ones you build yourself. I hope for your sake that this is true. And it makes sense to me.
I run a 2.2 system myself, and think it's the way to go. At least for me, in my small room.
And I grew up in my dad's garage too. He owned a little body shop in Newport RI when I was growing up.
Sure did teach me a lot about not having to pay people to fix, and/or build things for you. Which sure does come in handy nowadays. Since labor is almost always the most expensive part of anything.
We fixed almost everything ourselves. And even built our own frame pulling machine. Although we did have to have a guy come in and put the pots in the cement floor so we had something sturdy to anchor to. We did all the rest though. ✌️
fun fact!
your dinas project speaker are powered by this amp 2 years ago when i`ve done it i have 4.0 amp with active crossover and adjustable frequency for the crossover independent volume and general volume for all the controls
That’s awesome!
Is it able to be bridged? I would love to use it to power my 800watt rated 15” rfc pa subwoofer (efficiency 92db) + two very efficient full range tops, is that realistic?
Yes, you can bridge two of the channels for a subwoofer, and use the other two for FR drivers. You can customize the crossover point etc in Sigma Studio as well
My biggest concern is that i wont be able to figure out how to setup the DSP when i begin using sigmastudios. It looks kinda complicated. But the KAB-4100 is the only amp under $100 i can find that is 4 channels with a lot of power and has a DSP, so i think im gonna have to go for it. also need to figure out how to hook up a secondary amp for a 10" sub so i can make a 4.1 channel party speaker...

Where is the catch? Noise in dsp? taps?
I got one - just started messing with it. Notice one concern, I get noise/hiss when nothing is playing. Anyone else notice that?
Outside of that, what you can do with sigma studio is amazing! Can't wait to spend more time with it.
Yeah, this is a cheap amp so I'm not shocked it has a high noise floor
I noticed the same issue with Arylic 2.1, I'm pretty sure it's a problem of those cheap DSP chips.
@@tomkocur Gotcha. Get what ya pay for I guess.
Pity you didn't tell is the audio specs, and what power options (other than the shown battery) are available.
They have multiple different boards. If you follow the link in the description of the video, you can see the other boards they offer.
Could this be used for bassshakers? Sorry I’m a noob with the whole ohm thing
Yes it has to be within 4 and 8 ohms
Is it possible to do an XLR/TLS balanced analog input with this?
thats a good question.

I have the programming board, however it seems that you need to leave it attached to the amplifier board? because the settings you saved, are to the programming board, and not to the amplifier board.
No, you don’t have to leave the ICP connected to the empire board. They CP is just used to communicate between the computer and that board. Once you send it to the amplifier board and save it, it stays on the board.
IM NEW and a little confused, is this used as a crossover for diy speaker builds or is this just to figure out what crossovers are needed for the build?
You can use it as either or. However with the two-way example project that I was showing you. There are four speaker outputs on this board. They have separated those outputs. To those outputs would power the two tweeters and two of those would power the woofers. You use the program to design the crossover. That means there's no passive components necessary. This will all be done with the software.
Tpa3251 have nice board and not so old than tda7498e
this card should have usb on the card! if I am going to make a good speaker then I must be able to adjust more than once. there should be adjustment via bluettooth.
is it possible to buy a card with only this DSP?
You can adjust it as many times as you want. Heck you can use it in one project and then use it in a completely different type of project later if you wanted to. You just need to re hook up your incircuit programmer to it to program it. I'm actually glad it doesn't have the incircuit programmer built in. One, every amplifier would be more expensive. Which is unnecessary since you only need one of them to program as many boards as you want to program (with as many different variations as you want). And two it would make it a larger unit. But it would make it more convenient to program if it was built in.
I have a simpler adau1701-based board but wasn't satisified with DAC/ADC performance. It's possible to connect USB interface to it and two DACs over i2s but stuff like this is way beyond my knowledge...
Would be interesting to see how this goes compared to buying a Mini DSP 2x8 or two 2x4 and using some used class AB amps I have.
I wonder if the "4x100W" class D board would be as good as the separate amps in terms of power and noise
Wondom also offers a dsp board without amp. Would be similair to the 2x4 but much cheaper.
@@lennarth.3383 you can't make similar and much cheaper. These cheap DSPs have audible tradeoffs. They're only usable for small/portable speakers, where you don't really care about fidelity.
@@tomkocur So true. People make it sound like these china boards are mana from heaven for nearly no cost. Either people praising this havn’ any idea of quality and fidelity, or they have an agenda cause they sell the shit. On another matter .. all those td amps are not even close to be considdered hi-fi and their wattage claims are utter bs. It is possible to build a quality class D amp but it will cost some serious design effort, and I have yet to see any class D amp that actually deliver the same ammount of sound pressure/watt compared to an old school class A/B amp with a decent designed power supply. Have tried Pro level amps made for live music that have 1000’s of claimed watts in 8ohm, and a 30 year old 200w a/b amp weighing almost the same as Its age in kg, totally oblitterates it, playing considderably louder, so if you want some cheap watts considder looking for really old but quality build poweramps used because people don’t want to carry them arround anymore. New power amps that cost a fraction and weighs almost nothing is almost always shit.
@@mrdali67 The Dayton-board is a rebrand of sure/wondom. Technically all three boards are the same. In a nutshell: The Dayton-board is chinese mana from heaven sold at a higher price tag. At least here in Europe.
Serious question, is there a headphone amplifier that has these dsp features or chip? Can sigma studio work to dsp the headphone output on the computer directly? Is there good software that can dsp the headphone output directly with these features on pc or Mac?
With headphones the only DSP function that matters is eq, and there are lots of ways to EQ headphones
Check out Equalizer APO
Would like just the dsp without the amp.
Can KABD dsp do 4-way crossover for both left and right?
Each board has four channels. So you can do four channels on each board. If you need a channels, you will need two of these boards.
one board can do 8channels, but can only output 4ch, so in theory yes, you can, but only using extra amps or dacs with i2s inputs :) @@Toid
How many frequencies can you adjust at one time? 5 pcs. Normally you can not adjust good sound until you get to 15 bond eq.
Have this EQ. for all channels?
One for treble and one separately for bass / midrange?
has dsp / amplified hissing? many digital processors and class-d have hoss.
I have used mosconi dsp 6to8 and it does not have a pop free start. but there is a very loud bang in the bass speaker and it has a hiss
You can EQ this is much or as little as you want. You want limited like you used to be with just a normal parametric EQ. Like I said with the potentiometer, you can program that to do whatever you want. You can use it to switch crossover frequencies, change certain frequencies volume or even change the volume of the entire range of each individual driver. It's really your imagination that is going to limit this unit more than anything else.
Don't confuse parametric EQ and graphic EQ. The latter does indeed require lots of bands to be of any use in correcting narrow deviations. The former allows control over center frequency and Q per band as well as level, so fewer bands are generally required unless the driver is a total mess.
@@naturalverities that's a great point. With parametric EQ you have the ability to adjust the Q which helps you fine tune how narrow or wide of frequencies you can adjust. Great point! 👍
@@naturalverities Ok. I have adjusted a lot of EQ. in PA. world and in car stereo and Home hifi.
Even parametric EQ in car.
often it is more than 5 frequencies you have to adjust at a time. Then I talk about adjusting to get the best possible sound.
Take for example SEAS speakers from Norway which are seen by many as very good speakers. In reality, they have a sound type that requires lowering of several frequencies that do not produce as good sound. Seas has its own sound type which is not the best.
@@ford1546 each parametric EQ can handle up to 15 bands. However, if that is not enough, you can just add another parametric EQ in the software for an additional 15 bands (30 total). As far as I know, there are no limitations to how many you can add. And if there is, I haven't found it yet.
Is it possible to add a subwoofer to this? So there would be 2 tweeters, 2 woofers, and a sub?
The boards can be Daisy chained together. So in that example you would end up having two boards. A mono channel board for the subwoofer and a 4-channel board for the tweeters and woofers. Of course that's assuming that you're doing all active crossover. If you're doing a passive crossover then you could use just the four channel. One channel would be for your left speaker one channel would be for your right speaker and the third channel would be for your subwoofer and you'd have one channel left over.
@@Toid Thanks for the reply! I was indeed thinking of an active crossover for the woofers and tweeter. Is it overkill to daisy chain a second Dayton KABD just for a single subwoofer channel? Is there a more appropriate amplifier with dsp I could daisy chain to the subwoofer?
@@micahwhite4973 I guess it depends on what you're trying to go for. But I like the idea of daisy chaining them because then you can change the crossover point between all of them at any point in the same program. It just makes integration a little bit easier. But if you want to get a separate just subwoofer amplifier you could. I'm not sure of any that include DSP like this
My question on this is whether or not there is a way to run sigmastudio or a similar program that can set up these DSP's on a Linux PC? I've searched the internet high and low and have found next to nothing that is relevant to this question.
I doubt it. But you would need to ask Sigma studios
@@Toid Unfortunately I've already reviewed their site for the information and they pretty much give any OS other than Windows the middle finger and move on. Thus the reason I was hoping that someone here might have an alternative or a work around to use Linux. Guess I'll keep searching. Thanks for the reply.
This is stupid cool. You did not mention the power output
Good call. It depends on which one you get. The one that I have is a four channel amplifier that is capable of up to 100 watts per channel. So 400watts total. But they have other boards that are smaller.
@@Toid Yep, and for the full power, you need to make sure you have the right amount of amps as well as wattage. Easy equation: power needed = speaker power (e.g. 200w) / amplifier efficiency (e.g. 0.85)
Then you take your calculated power needed and divide it by your voltage (e.g. 24v). That gives you your minimum amps needed for the power supply 😉
Sorry Nick, didn't mean to @ you. It was meant to just be a normal reply. 😅
Are you saying that a DIYer can use this and not use a physical, passive crossover? Or does this work in tandem w/ a passive crossover? FYI, I'm a speaker noob. I'd love to see a How To Build A 3-Way Studio Monitor Speaker video using this DSP.
Yep with this board you don't need a passive crossover at all. So if you wanted to do a three-way you would want two of these amplifiers. Once again Parts Express is done all the work for you so you just need to download the template and fine tune it for your application. If you do decide to get some, feel free to use the link in the description, it does have the channel out. If you need anything else feel free to reach out
@@Toid I'd invest some money and time on a DIY build that you build on your channel. I'd like a smallish build: 3-way w/ no bigger than a 6" woofer, maybe even a 5". Then the mid and tweeter of course. All within a powered cabinet. Purpose would be as a studio monitor w/ a slightly elevated mid frequencies (500-3000) to highlight voice. Budget at $300/speaker or less, including supplies for plywood box and solid hardwood (Maple?) baffle.

I will never throw away a speaker that stopped working ever again... I had an Altec Stream X speaker that just stopped working one day out of the blue. I opened it up and tried to figure it out but couldn't, so I threw it away. It'd been the perfect place for one of these boards... the 2 X 30 w. It had a nice sound for what it was. Even had the battery operated function built right in. Only thing this board wouldn't have had was ability to use Chromecast. Otherwise this would've dropped right in. I'm going to have to go looking to see if maybe this is still laying around somewhere... I know I still have the front speaker grill part and the power cord cuz I remember it was 18v. It was useful for my 10" portable fans. I'm going to look... I'll let you know. In the meantime, anyone know if I can get the Chromecast parts off the old pieces???
Google and Alexa are coming together to work on more and more things and I'm happy about that. Instead of fighting for the space they seem to be getting along nicely and I'm finding I can use them more than ever... like asking Alexa to show me a Wyze camera on Google Chromecast on my TV...
But is the fan noisy? They should look into fanless cooling.
It would probably be possible to replace the heat sink/fan with a larger passive heatsink.
I have two of these. I have driven them hard for long periods of time and only I have only seen the fan go on once. The heat sink is fairly large compared to similar class d amps and they barely get warm. I think the fan is overkill and only comes on in extreme situations.
I don't know why most home audio guys sleep on using a DSP....it is far more better than a passive crossover
Hi presets are not downloadable any more clonger you sent me the presets for 4100 THX
So Dayton Audio just rebranded Wondom JAB5 and charges triple price for it ?!?
I just priced the Wondom JAB5 and all the rest of those amps. They are same price as Dayton versions within a couple dollars. Throw in some customer service in the USA and it seems like a good deal to me.
Thanks to you for discover this product.
But a DSP after so many compressions and format change in the audio line is not terrible!
A title converted in MP3, playing on a smartphone, converted in bluetooth, decoded from bluetooth, and put in an other AD-DA converter like a DSP, and finally amplified with a class D... Compact but horrible in output quality!!!!!!
For less money and the same powerfull TDA amplifier(only for sub), i build much better triple amplification...
Very interresting channel!! Continue!!
Sigma Studio was designed for professional chip programmers on brand name devices. These Bose, JBL, Sony guys have been cheating for the past decade. Now we DIYers have the same cheat codes.
sure/wondom boards ARE NOT THE SAME because they don't have DSP built in.
The point of the video is about the built in DSP.
The Jab series do have DSP. Here's the Wondom Jab 5: store.sure-electronics.com/product/AA-JA33286
My 2x4HD just got made obsolete
If someone who has experience using miniDSP could through light in future how’s the dsp in Dayton example time alignment. I am not even talking of Dirac. Also miniDSP u can use any amp with Dayton u r stuck. I want to see if Dayton 4x100 with the best power supply can it play 70% volume without distortion. Dayton should make a tpa 3255 model too for higher amp users.

have any of the people comenting here seen a tru 4x100w RMS amplifier ? it has about 25kg and massive components inside. this P.O.S. will burn in 2 minutes. maybe 4X5w RMS.
ever heard of class d?
I'm building the Wolverine DIY amplifier. Much more powerful.
I checked that Wolverine Amp out. If i had more confidence I might have looked into that. Its okay though I am very curious to see if my own plan will work out.
@@halrichard1969 is easier than it looks. It's my first build.
i have a triTrix kit of 3 drivers in each speaker
so that means i'll have to buy 2 of this 4 channels amps
at 90usd Each Before shipping that's 200 usd after shipping.
it's not the same as 60usd worth of crossover parts.
The tritrix is a 2-way design using 3 drivers meaning you would only need one of these amplifiers. The two woofers, since they play the same frequency range,
would be on one channel of the amplifier. While the tweeter would be on the other. Is that more expensive than the crossover parts? Sure. But this also is your amplifier, so I guess that would depend on whether you needed an amplifier or not. But in general, going active is not necessarily cheaper, however it is an option if you desire.
@@Toid your right if i can connect the two drivers to same one its only 90usd for all the needed parts. so u connect this directly to the tv ? and speakers directly to this ? and then no tinkerinb with settings to make it know your specific drivers ?
way better to just buy the RAZOR, Power Acoustik RZ4‐2000DSP , Same exact chip, 75 watts a channels, , super clean sound AND you can buy it for as little as 130 if you catch it on sale, not lonly but it comes with all the pieces, blutooth, usb, and a case, unlike this thing
Sounds like a pretty decent deal. The only issue is it doesn’t appear that it can connect to Sigma Studios. Instead it relies on its own DSP app. That’s unfortunate, because Sigma Studios is a huge reason why this amplifier is so powerful. Maybe someday they can implement it, but until then it won’t be able to compete with something like this.
@@Toid i agree to a degree . . however for system tuning it has every you could want 10 band parametric. .selectable q freq and 20db +/- every cross over type filter, both high pass low pass and (band pass) any slope 6 12 18 24 on any channel plus time alighment ment. . .for the money it hard to beat especially if you know what your doing with it. . .only this missing is a limter
Why does the pig keep switching sides?
Trying to find legitimate power amp specs for these all in one boards is almost impossible. Probably because the manufacturer wants to hide the truth of their capabilities. For now these things are simply novelties.
They list the amp and dsp chip numbers in the product overview. The rest of the specs are in the product manual. Took like 15 seconds. That’s the main reason I like parts express. They may not have the best stuff on the market but they offer specs and graphs of everything.
a 10 minute commercial for the amplifier.
If you consider information a commercial. Then I guess every video that informs someone is. It’s your responsibility to do with that information what you want.
If youre getting paid to "review" this product then its a commercial. all you do is review it, didnt say how it works or how to do much of anything but say how great it is. @@Toid
@@TheStonedSpidR first I didn’t get paid. If I do, I disclose that. Second, this video explains what you can do with this and what you can’t. It’s purely informative for you to decide if it’ll work for your project. I even explained that Parts Express has project files for those that are concerned with Sigma Studios. If someone wants more in-depth resources that Parts Express provides. They’ll have to research that on their own. At no time did I say this is a comprehensive video on how to use Sigma Studios.
Just use the real product made by Wondom, you are a advertising Daytons rebranding which is 50$ more expensive.
Can you show me where to find the wondom products so i can go there
None of this matters if you cant prove its performance. Still want to know if the wattage claimed is real. I know its only a few watts, but we have been burned before.
