#SMD #DD1+ #distortiondetector - ยานยนต์และพาหนะ
Ok my name is in the title of your video so you know what is coming next.
LIST OF YOUR ERRORS
1. Video description. RF paper on building your own high passed speaker project is not 1/10 the price. It's twice that, WITHOUT LABOR, is your time is worthless? You just valued it at $0.00 per hour
2. Video description. A High Passed Speaker is not a Distortion Detector. RF you listening?
3. 1:39 No headunit is 0.5V out. But if it was you just put the probes on the amp to set everything, headunit, processors, amp, all measurable THROUGH the amplifier. This is actually the preferred method since this way you can see distortion of outputs AND INPUTS of all components in the signal path. No need to plug headunit into DD-1+, ever, unless you want to see how many volts come out of it.
4. At 9:42, at this point you are supposed to press READ and then switch to the OVERLAP track. EVERYTHING FROM THIS POINT ON IS INVALID SINCE YOU DIDN'T. THERE IS NO reason for anyone to watch this video past 9:42.
(I'll keep watching to see what other misinformation you are spreading)
5. 13:43 The voltmeter on your scope is a cheap AC averaging meter that calculates AC RMS from any waveform, based on the math for calculating the RMS of a sine wave. The math doesn't apply to square waves hence the error on your scope. The DD-1+ voltmeter looks at the peak of the waveform, any waveform and determines what the maximum clean sine wave voltage would be that fits in the "rails" of the waveform.
6. 16:19 So you're saying if someone adjusts their gains for maximum clean output, and then you turn up the EQ or level more it clips???? NO SHIT
7. 17:32 And how would using your scope or the my first electronics project from RF to avoid these problems? It can't.
8. 19:34 This is a problem with this headunit. A better headunit has trim level adjustment for all sources, or an engineering team that took care to make sure all sources had the same gain before the design was mass produced.
9. 20:30 The DD-1+ shows when distortion reaches 1%
10. 23:32 Please describe this "more" that the scope tells you
11. 25:12 yes
12. 29:01 this has nothing to do with the DD-1+
13. 30:28 this is exactly why it is best to do all measuring at amplifier output
14. 31:04 the quick blink of the LED when increasing level is the 3 stage autoranger switching ranges, mentioned in manual
15. 32:10 you just set it with NO OVERLAP?! EVERYTHING after this is also invalid.
16. 34:14 voice coil is hotter now and the impedance of your woofer is higher, so in turn it got less power. 20 less watts = 0.1dB less, nothing to see here.
17. 39:00 You clipped it hard, of course it was louder and put out more power. Now try using the DD-1+ properly and put 5dB overlap in it and do SPL run and make that video.
18. 40:41 You showed us that you STILL didn't use it right, even though 20,000 people already know how to use them perfectly everyday.
Lmao 🙏👍💪👊
Tony D Mike drop
I wish I could spam the comment section with his comment so everyone reads it
He will probably show us another screen shot of his phone saying he did it wrong again as another test to see how people would react and delete this and make another video
And probably mess it up again lmao
One good advice: read the instructions! You are using it wrong!
Very much so it's not being used right...
Clown
Yup. Using it wrong
You are using it wrong and 3 diffrent ways.. Giving bad info.. Not cool
You have a 25% thumbs up from me, only because you know how to use an O-Scope. When using the DD1+, you have to hit the read before making adjustments. That’s what you did wrong. I have the original DD1HV and every system I’ve installed to date functions the same way since installed, except for the looser suspension from long usage. You didn’t read the instructions fully and correctly. Also another thing, listening for distortion is a no no. If you really know what you’re doing, which as time goes on I’m noticing you don’t in some aspects, you’d advise against it because you can’t hear distortion at the most minuscule scale. Which in time will destroy a great build. Ever had a tweeter drop out on a crossover? That’s because of clipping. Bet one of you in the comments had it happen, and didn’t hear your tweeter was clipping.... If you’re daily driving your system, that’s when these things matter, if you’re doing SPL, DC and AC voltage is your friend. Not so much distortion detection, and o scopes. When I hear people trashing devices that work for those who don’t come from an extensive background of before “easy of use” products, usually hate they didn’t think about inventing it. You pay for technology, and The DD1+ is a great device. An O scope is better because you can see the wave. That’s really the only advantage. Steve says it to everyone, buy an O scope and learn that first. Redo the test correctly, and you will understand how the unit works. As for the comments on here, throwing shade at someone because they are innovative is foul, and disrespectful and makes guys not want to be in the audio field. We all love our cars, audio, and tools. Would you get mad at Eric O (South Main Auto) for using an Onyx drill over a snap on drill? No, because the persons knowledge of how to use the device is all that Matter. Be respectful, as for you sir EMF, you do a lot of tests that are accurate, but this one for sure needs to be redone. Talk with Steve.
Best and most respectful comment I've seen yet.
FoSgAtExPoWeR thank you. I try to be respectful to everyone and every aspect when it comes to my profession. Makes for a better crowd and understanding.

I'm just commenting to increase the likelihood of the video being pushed by TH-cam and to stir the pot more
😂😂😂
Hitting the like button helps more than a comment
My kind of troll. A troll after my own troll heart.
my jogger
anyways, these devices are fairly simple, you build a sharp notch filter for 40hz and 1khz, when something starts to distort (meaning you have harmonics) those frequencies make it past the notch filter, then it takes the level of signal that makes it past the notch filter, does a calculation against the level of fundamental frequency in a microcontroller, and if it is >=1% THD it lights the LED
Moral of the story, put a clipping light on your dash to make sure different EQ or recording material dont jack your stuff up.
Gunk smd om-1 :)
@@brandonjohnson7559 im not sure how relevant that would be. The om-1 is setup according to what you do with oscope or dd1. The issue is when you change your eq or play source material with different db than you did your initial settings with. My understanding is the om-1 is just going to show a red light when you go past what your initial settings are. That will change if you bump your eq or play from different source with higher db recording. I think a true clip light like Sundown has with their amps is best.
Idiot
Agreed. Any song just keep adding gain till the light comes on. A clip indicator is all you need assuming it’s accurate. But that’s not such a safe assumption. Also a slight amount of clipping is acceptable. And all clip indicators have different variances. For example 1.5% distortion or 10%. But yea. A good clipping light will satisfy most people and yea it will take the songs levels into account which is important. The dd1 is perfect if you play specific songs or tones. Simple.
@@meade9167 a more productive comment would entail "why" this is such a bad idea. Db increases in source material played and eq adjustments are legitimate issues.
Nice video. With DD1 it may be clean without a load on the amp , but when your sub or subs are connected it actually loads the amp down more which will still cause clipping.so I think the oscope is still better. I think you can still make a little adjustment on your bass boost or bass level on your source unit then set your gains.
My take on it is the DD1 as with all SMD products are way over priced and no one uses the tool correctly in that it is a tool that identifies a danger zone but EVERYONE using it gives themselves no head room. By that i mean if your head unit clips at X volume but you choose to ONLY go 1 volume point below you stayed to close to the danger zone. The same applies to the amplifier EVERYONE backs off till the light goes off but that is only .1-.2volt lower.. Tolerances are to tight and variables are to large. Set head unit 2 below clipping with the unit EQ/Loudness and all to your normal preferred setting. Then move to the amp setting the crossovers with 0db tone tracks then and only then set gains to find clip drop the amps voltage a whole .5volts from clipping and do as many scenarios as you can change music, tones, and sources to verify it is still clean. Once you have done all of that verify your output wattage/voltage needed on amp output to match the speakers rms wattages and if your short shrug your shoulders say welp i did my best and the system will last for years...
I set my gains with a $20 1965 rca oscilloscope
Awesome Sauce!!!!
Better then anything else you could use. Oscilloscope for the win
I agree,I am going with an O scope.Amazons got one for $80.00.Thank you.Thats the next piece of equipment I'm getting.I love this stuff.
Very though and informative. Your gonna clip so open your ears is basically how it goes. I use a speaker with a resister to set gains and it works well as a starting point.
i like both ways and since im just starting my own audio shop i want to learn as many ways to make my customers happy
charles irby cool man!!! That’s exciting! What’s your shops name? Do you have an Instagram or Facebook?
your first mistake, thinking you can make fools happy
I use a piezo tweeter with a 2.2uf capacitor in series to set the gain of a subwoofer amp, it would make noises when the signal is clipped
no you don't.
Did you get that idea from Barevids?
River Alley yes i did
I have always done it the same way you just mentioned, Steve Meade replied to my comment on the last video emf did and said even using that method you could still be off might not be getting the full potential of the amp. After giving it some thought I think I'm gonna bite the bullet and purchase a dd-1+ and an oscope just to be on the safe side. When you you contemplate the cost of the this equipment compared to what you spend on good quality subs and amps I figured it's worth it plus why not get the most out of my sundown sa12's and skar 2k. Just my 2 cents.
except that doesn't work when you use 40 Hertz
Im here for the comments 🤣
Why all the dislikes
@@Bighotwheelhunter Ready Tony D'Amore's comment, showing how everything after 9 minutes is completely false information.
I like car audio. That's why I'm here. Please set your gains however you want :) dd1,ear,dmm, o-scope. Just keep bassing on
Yup i agree.....i set my gains by ear and it sounds like king kong is trying to get out my trunk!!!!!...... Certified block banger!!! 2 15 inch orion hcca dvc 2ohm at first i had it hooked up to a cheap planet audio 1500.1 anarchy amp class a/b. I was very impressed that i was able to wire it at 1/2ohm and did not give me problems at all. It got hot as hell tho... Fry an egg on that bitch lol. After that i got a cheater amp that my homeboy had got for me. It said 50 watts 😂😂 and it was long AF loli didnt know about those amps at that time. It was real greedy with the cars electrical ENERGY HOG!!!!!!. my current set up i had invested in a Audio control 1500.1 and i got blessed somehow i came up on the same amp a second time for free. 2 audio control 1500.1 and 2 orion hcca 12 inch
I love the truth in your videos. I've bin a installer for 25 years and cant agree with u more. Keep up the good work
Thanks, was very educational. I own a oscope but when the dd1 I took it as accurate myself. Having checked it with the oscope to verify. But it totally makes sense if you switch to cd vs usb. I didnt even consider that. Also see know how it could introduce clipping if I change anything from where it was set at with the dd1.
I am an old school car audio guy and I would have loved to have tools like this back in the day.
We used o scopes, and the RTA to set up systems. However in the very early days it was set the volume of the head unit to 3/4 volume then turn up the amp gains until distortion was detected by ear.
One thing that the guy in the video did touch on that seems to be accurate is the change in output depending on the source used.
I often use my Bluetooth connection and my phone for my source, however when I change over to my usb or head unit, the output seems to be much higher even though the volume has not changed.
This is on my factory audio system, and I could see the possibility of this occurring in an aftermarket head unit.
Just an observation of my particular situation and it may be very different from others out there.
So it would seem that an individual doing the tuning may want to use all sources that they may used and check them all with DD-1 to ensure no distortion exists.
bluetooth is problem, go direct with 3.5mm audio jack if head unit is equipped
think of wifi vs ethernet cable
Thanks Sean. Videos are always informative. Love the old school spl trick at the end of the video. I still have and use the 3 banhammers from 2016. The 3 scv 2000's died in 2018 (power supply problems) I have Phoenix go ti elite amps now. Ok my question I've set up my system using the dd1+ and havent noticed a problem. But the explanation on the 3 and 6 db over lap does have me concerned for my system as it is the mids and highs that does use that overlap. I think I'm getting what your saying. Is I should be more focused on the extra head room that I know is clean. Instead of essentially over thinking it and providing a over lap that may distort at a 0 db signal? As always love the equipment. I do use SMd and EMF with no problems. Just want your thoughts about what I was talking about
I'm a Gen-X digital VOM & O scope user.
I like SMD accessories, I still rather set my gains old school. I haven't toasted a subwoofer yet, unless that was the mission I was currently on.
Get you some Neo connections from him. Those are well worth your $.
I use one of those 30$ cheap oscope it works amazing for tuning amps
You're not going to get a good enough resolution on one of those to actually see true clipping. But you'll get close enough for the $30
DSO150 spec ftw
I do the ear. Ear will. Ear will never hirt your speakers! Always do double on the RMS on what you exspect though
I use a dso150 works perfect I sold my dd1
@@imthirstyh2o330 I use same one! It works awesome
I have never fried any amp and or sub when setting gains with my dd1 , with that being said it works for me, yes oscilloscope would be best but dd1 makes me money and works just fine.

@@markdaniels8521 im new to the party. Care to explain? Thanks
I dont necessary disagree with alot of this, but being in music production for over 20+ years i can safely say not much of the car audio world truly understand how all of this actually works. Best example i always hear about CLIPPING, but there is a huge im mean huge difference from soft clipping an full on square wave which is also something i see in alot of these types of videos. The quote smooth rounded is a sine as advertised in most videos like these ,but full on hard clipping is a square wave which is almost never explained in videos like these. In fact for several months ive watched similar videos to this an there is always a ton of misinformation or information thats not made completely clear.
Me toooooo 15 years that i produce electronic music and in some group chats on Facebook about car audio people talk about things without having a clue of what they're saying 😂😂😂
Poking that SMD hornet's nest....lol
Playing with fire son!!!
Haha, annoying fire!
When you but the dd-1 in the instructions it gives you options and tracks for different db overlap settings. I believe it's 0db, -5db, -10db and -15db. For the 40hz and 1khz track. Bass boost is always a no no regardless. I'm not sure if the track choices you used have much to do with your results but I'd be curious to see you do all the above with all the different options from the dd-1 or dd-1 + manual. Then again I'm still only half way through this video... I think I'm wrong about the different db overlap settings it says in the manual. It may have been -5db, -7db and -10db. Makes more sense. I haven't checked the booklet yet.
he is correct and so are you, anything done at head unit effects the out come of the hole system, I know many I have setup by ear only and was flawless give or take depending on some of the piss poor recording studio's, then 2 or 3 days pass, someone tells them it sounds like garbage, come to find out they added more bass and treble and I could not get them to understand that effect the overall sound of everything @EMF Audio and @meade916 y'all keep up the good work and FK WHAT OTHERS THINK, because in certain sisution, we get the big head and know all and no one can tell us diff ROFLMOAO KEEP BOOMING
I love your video.very informative!
Reading through the comments I am most impressed with Tony D’Amore’s approach and comments.
I confess to not be sure what the relevance of setting gain overlap is to detecting distortion, perhaps I missed that.
I don’t have a DD 1, I have a Fluke scopemeter to for isolated measurements, but can see how it’s useful.
The thing is that most us who have been in car audio since the golden days are really and truly too old to be indulging in handbags at dawn, right..
grandhubert preach brother
I don’t understand why all this fuss over the DD1.
The standout product is the AM1, I can’t think of many other instruments that measure power factor, but even then it falls into the “nice to have” rather than essential category in my opinion.
If people are buying an oscilloscope for audio make sure it has a useable FFT function. That way it can show distortion and be used as a RTA.
grandhubert thanks for the heads up. What is considered a usuable FFT.
ptstrong3 for this purpose I would consider fit for purpose to be the ability to resolve harmonics of ~ -30dB with respect to to the fundamental
grandhubert thanks for the info
I own a dd1. Wish I had bought o scope . This video is accurate😎.
So now I set my EQ the way I likey and then go to clipping with the setup.

The one thing I like about pioneer head units is the source level adjustment when setting gains you can level out the difference in sources.
Did not know that. Pioneer for the win on an After market HU. Super Tuner is the King.
Just so you're aware, you may upload the videos with peaks at 0db, but youtube messes with the audio. I'm not sure of everything it does, but it could change the peak level and average level.
analog always smoked digital on ever aspect setup old school cassette deck vs cd, then tell me which has better quality, I'll take analog any-day
same goes with signals, just look at how normal radio station work vs digital radio, with analog you can still make out to a certain point of whats being said, now digital you don't get shti Siriusxm is just one example
Ya i think in the instructions and pre calibration it says to set your bass boost or volume bass knob if your amp has one to max. Then set your gains from that point so if you add boost it wont clip.
Sure but keep in mind you still wont get all the power from your amp so its just wasted.

You would also with an oscilloscope have a difference with each different source so it doesn’t matter what tool you use to adjust for clipping you will have to change your gains for each different source
Using the same source with different track volumes would also change that. All reasons the best tool to use is your ear, and confidence building tools are a waste of money.
@@EMFAudio probably is everybody doesn't have that ear some people can literally listen to distortion and hear no problems
@@d77543020 because they aren't told what to listen for. Most people figure it out, if it sounds bad, turn it down.
Seems like I should clip each source and set gains for the source that clips first. If there is a consistent difference then you should increase the level of that different individual source to match the source that distorted first.
If you want to eq it's simple. Set gain at 0db. Now take away from flat to form your desired curve.
Ideally we want to do this last step with an RTA.
You can clip even if you set it with the O-Scope. Audiophiles take into account everything when they set their equipment up. That why you always verify after changing settings. And depending on how audio is recorded is going to make a difference. The tool does what its supposed to do. But it doesn't matter if you use an o scope or not, you change something, then expect different results.
I have used the DD-1 and CC-1 on every system I have built and every time I have seen DB gains... EVERYTIME. For the unity we try and preach to the younger generation, having the older audio guys conduct themselves this way is a huge step back wards. Just my 2 cents.

@@Des420 true
Des420 I have paid plenty of attention, my comment was directed at both parties. No names mentioned because I though I got my point across.
I set my gains with my bass knob at around 3/4 and checked my clip indicator with a scope. It’s pretty damn accurate. If I’m cranking it up I put my bass knob to where i set my gains and I can see if I’m clipping or not at the volume level I set my gains. It’s about the safest way to prevent clipping outside of having a scope sitting on your dash lol. I check everything pretty regularly but I also have a 4425 PicoScope, a snap on vantage legend, and a couple of other handheld scopes laying around.
Wow, ive argued this without a dd1. Im not a rocket scientist or anything but it seemed like common sense that if you set the hd to clip then anything you add like you said bass or boost anything will clip. I got reemed out with technical words which i couldnt argue because hell i had no idea what the words even ment. Now what happens when you set everything and you use Spotify and the recording isnt right like they added bass boost on the recording, clipping. You just made my night with this info video.
STEVE MEADE HAS ENTERED THE CHATROOM
Love your videos. You can't just turn any head unit up all the way and tune it by ear. I've done that before on a friend's build and I had to go back with the dd-1 to correct it and now it sounds clean and it's a little louder. Before that, the amp for the sub would go into protect. Not all head units can go all the way on volume. I've always tuned by guessing the head unit volume and hearing distortion from the subs but now it's so much easier with the dd-1. I'm not paying extra for the dd-1+ though. That's way too much. That oscilloscope you have is more accurate. I should have gotten one of those instead. Again, love your videos. I've learned a lot from watching them.
Learn to use an oscilloscope! It is easy! The problem is, that people think they need a special tool because they are afraid of the learning curve with an oscilloscope. If however you are clever enough to use this fine specialty product, you may if fact be clever enough to use and interpret the oscilloscope with ease. The oscilloscope has a multitude of uses and applications including diagnosing modern cars. It is a MUST HAVE for anyone interested in sound, automotive repair, or electronics in general.
If I commented on this before forgive me. So if I’m understanding correctly, what ever source you use to set gains with a DD 1+, any addition ( bass boost level controls whatever) downstream of that source can and most likely will cause clipping. So I’m thinking if you set the gains AFTER you’ve made the adjustments Bass boost etc you want to make using the DD 1+ as opposed to before the sound processors etc you will be good. Is that correct or make sense?? Thanks for always informing and being patient. You’re cool beans.
What someone should take away from this video if they're looking for valuable info or facts:
Setting your gains should start with finding the limits of the head unit and all other gain settings shoild be set with any eq settings (bass boost, head unit eq, phone or bluetooth source equalization, bass knobs.. etc) maxed out to the highest degree the intended user would ever use.. The key to correct and safe equalization and amplification would always be to decrease frequencies levels rather than increase them.. The part i don't subscribe to wholeheartedly is that distortion is wrong and every un-rounded waveform is an arrow from satans bow.. Clipping is undesirable and destructive for sure but i believe there are hundreds of thousands of overindulgent bass heads in the world running equipment for years even decades and their systems regularly experience distortion to a small degree.. I would not set a customer's system to allow a signal that distorted to ever pass through the output but a smart person knows that what's being said about line level, eq and clipping are really just no-brainers and if you can argue against a point that is 100% legit truth (easiy proven facts) then you don't need to even watch these videos because physics and the world that you live in are within the fantasy realm that nobody else can touch taste or see anyway, so just turn it all up to fuggin' eleven and ignore the advice of anybody not sharing your cartoon coccoon. Sorry for typos and long winded reply.. Some of y'all just fuggin' suck!

Great vid!
Just an interesting thing I encountered some years ago.
I have a track that surpasses the 0 db range with no clipping. How is that possible? I have no idea because I got it off the internet years ago. The track sounds like it’s +6 dbs. It’s the ONLY track in my life I have ever encountered this. I’m assuming there is an error in the file header that causes this. I’m not sure. I play this song in my car and distorts. I play it on any player on my computer and it distorts. I load it in my audio editing program and it shows distortion because it’s past the 0 dB limit. But here’s the thing, I have a program called Winamp and it comes with a preamp adjustment on the left side. As I lower the preamp gain on the left side, guess what?; all the distortion is gone and the audio sounds clean! This is the rarest file I have ever encountered in my life!
You have done magic, that's my guess.

... i miss winamp now asshole! why oh why did they ever sell out to fucking aol of all companies? WINAMP, IT REALLY KICKS THE LLAMA'S ASS!
I'm still going to figure out how to set my gains with a cheap oscilloscope. But my plan is to set it at 0db 1k tone file. And listen to quiet music like Tom Petty and see if I'm having to max the volume out (Max volume meaning the highest you can go on the head unit without it clipping out of the head unit). If I'm having to max the volume out, then I may try a -3db 1k tone file go reset the gains and see how that goes.
my cheap jensen HU goes up to 63, i can hear it start to clip ~48 and set the max to ~ 54 because some recordings (old ripped disks, aerosmith, boston, extreme ...) just need a little more gain and some bass boost to sound a little better. it might not clip 1% till 54 but i backed it off to 48 just to be safe. one of these days i'll find somone with the dd-1 just for giggles to see what it says.
i have a truck full of ADS speakers and my system sounds fantastic.
that is why I hate anything DIGITAL, can we bring back analog yet
I always figured if you use the dd-1 to set your gains, then after if you change any settings you could clip. Which always made me wonder what the point of the dd-1 is. I set my gain with dd-1 and on my alpine it was clean to vol 30, but went to 35. In my case once I set my head unit up, bass/mids/treble/crossover and all that... I usually set my bass to -3 or -4 after setting my sub amp with what the dd-1 manual refers to as "a happy medium of clarity and loudness" which I'm paraphrasing for of course lol. I forget what db overlap track it was for that setup though. I'd have to check the manual. Definitely wish I just stuck with using my ears to set gains like I did for 20 years lol.
Your last video disappeared, why? Anyway, without a dd1 or an oscilloscope I just set my amp with no distortion. I used my ears and the 75 percent rule and it worked for me.
I grew up installing in the late 80's and 90's. We didn't have these fancy tools and scopes were huge and cost thousands of dollars. Our ears never failed us back then!!
Probably hid it because he was getting trolled by smd fanboys
Shoo, I use a tweeter. Works every time.
Wow, you too? Disappointed
Any suggestions for a few different quality scopes that you know of?
I'm thinking about maxing the volts with an 0db recording but "marking where" using an inline bass knob to reduce the volts till it reads -5 db and another at -10db. Just as guide lines since the music might not be reputable. I can always turn it up and use my ear.
Thanks video
I’m guessing you never attend our industry conferences? Like this is a small world man. Bad info is bad. Tony is a beast!!!!!!!! Keep doing good work for us Tony!!!!
I'm no professional but it seems like the overlaps were set wrong do to user error.. I own nothing by or from smd,so I'm not brandwagoning but i think this is a bad representation. Like I said I'm no pro, I just like my music loud and low but this social media drama is senseless! ✌

I love your videos dude. Sorry I haven't been watching much lately. Very informative and I've been wondering about this since the dd1 came out just never did side by side testing. ❤EMF
Great job I just use my ear never blew a sub yet
Doing the levels on flat settings would be ok if the EQ'ing would be done to only remove humps and bulges, not to boost anything. And that's how it should be. Though a few dB boost here and there would probably not be the end of the world. I would probably prefer to set some basic levels for measuring and setting out the system (EQ, delays, phases etc.) and only then do the final level setup. That way the boosts that change with the listeners taste and feeling could be kept to a minimum.
OT... And of course a system should be adjusted as a compromise between a flat response and the preferred contour of the listener (also with high output, the threshold of pain should also be considered). When someone actually starts hearing things that previously were left in the shadow of some over boosting or just crappy speakers/installation/whatever, I could bet that they would eventually prefer less boost (ie. loudness) for a clearer and more sophisticated sound stage. But that takes time, understanding and good gear.
Christmas eve.. New years eve.. I see it.
DB Bass heads welcome to the Q bass heads nightmare. Great video! !!!
I think these are good to find the maximum volume on your head unit and pre amp EQ, but after the amp I feel it’s best to use the oscilloscope.
why, just listen to the speaker cone pop, when it pops instead of boom, then there lays the distortion
I just watched 2 of your videos, AFTER i watched SM's vid on the returns where he praises the dd-1. which i commented on that i simply tune my system by ear. ovcourse he had to comment back that if i'm not using the dd-1 i can't be doing it right.
i've been doing it since before the 80's and as much as i might like some of SM's products, if i were to spend any $ on a tool, it would be a scope, not the dd-1
You forgot to show that a phone using Bluetooth can also clip depending on volume level as well. I have to keep my phone two clicks down from full volume or it clips hard.

mikes hobbie's and random stuff does your head unit have a source level adjustment?
@@jamesbondcaraudio4247 I don't believe so but even if it did it wouldn't solve it the clipping comes from my phone at full volume, it even does it using headphones with my phone. Depends on the phone itself as I've had phones in the past that didn't have the issue.
mikes hobbie's and random stuff got it brotha.
wow just wow
where can we get these test tones from and how you recommend we use flash drive or cd?
I make my own tones, there are various places you can download them or buy them on CD. I can't recommend either because either will give a different result per application.
First, Happy New Years and thanks for the info on the DD-1 because I was really thinking about purchasing one!
When did it become hard to set gains?
I'm kinda dumbstruck about that as well.
This^^^^^^^
The day EMF put out that first video.
i blame the overall decline in common sense that we've witnessed in popular culture over the past couple decades and the obsession with wringing every last watt you can out of your system while staying completely 100% clean. this is why headroom is a thing. if you have sufficient headroom it isn't really something you need to be concerned about.
@@buddykiller I agree, look at the cars of today... they are built just for that "less use of common sense" we see a light in the sideview mirror to let us know when it's safe to switch lanes... etc. Etc. Theres a plateau in which TH-cam can be educational... the rest of it is the new age wasting time and brain cells.
This video is hilarious and so are the comments, he's trying so hard to downplay equipment.
Lol he seems like a sour little baby . Every video I clicked on he’s talking shit about someone.
Why using different impedance would need to change gain setting? If you set it with subwoofers disconnected
If for example you were using a multimeter, the forumula is The sqaure root of Nominal RMS power(per channel) X Impedance. So a 100 watt at 4 ohms would require your gains to be set to 20 volts, but a 100 watt at 2 ohms would require your gains to be set to 14.14 volts. If you were to set the gains for hookup to a 4 ohm speaker, and then changed to a 2 ohm speaker, your gains would be set too high.
There's no such thing as gain overlap for clean, undistorted sound!
When you're dealing with audio material in digital domain and you don't know who how it is mixed, mastered or edited, there's a big change to find out what intersample peaking (ISP) is. Basically, when someone choose to normalize an audio track close to 0 dBFS, without having the available tools to know how that signal will look in analog domain, the moment that audio signal shape is reconstructed in analog domain, you will find out what intersample peaking is and are guaranteed to have a clipped signal before entering the amplifier.
If you see the waveform of a song in digital domain and you notice that it's peaking to -3 dBFS or lower, there may be a reason for this, like a decision made by the mixing and mastering engineers, in order to avoid clipping the audio signal when its original waveform is reconstructed in analog domain.
The secret to good sound is headroom! Headroom on mixing stage, headroom on mastering stage and headroom on playback stage!
Enjoy the music as it is and don't try to chase last ounces of power from the amplifiers, just because you paid for that power.
Music is dynamic by its very nature and those dynamics makes it sound good!
It is a waste of money, only thing you’re paying for is looks. Good video man at least someone explained how that thing really works

It could be useful if your amplifier doesn't have a clipping indicator but

It's not wrong of course to take a stance but how we treat people who don't vote like us, look like us, live like us or who we disagree with is pretty sad.......even something as insignificant as car audio (as compared to life itself), and the same dynamic seems to rear its ugly head, human nature!!!!!!

But what if.........there is worldwide impact and you and I play some role in the current state of our world.
I'd like to see you invent a bass knob that provides a distortion light implemented into it. IMO they should already be on the market and readily available.
You mean like most Sundown amps for the last 6 years?
I’ve had a bass knob with a distortion light since 2013
D4S JP23 has volts, temp, and clip in the same knob.
This makes me want to do a dedicated in dash o scope 🤔.
Not concerned with mids and highs as much.. just for the subs.. 3" coils way over powered need to stay set clean 😂
Shalamah the Brew I’ve done it and works amazingly
@@imthirstyh2o330 thank you for confirming. What unit are you using?
There’s no reason to do this. If you were to play music the scope wouldn’t display any discernible info. You’d need to play a tone and (should) also disconnect the speakers. Furthermore, mids and highs are FAR more sensitive to clipping than a sub. Which is why you’d set them with less overlap than a sub. You can learn a lot by not listening to this channel.
@@jtc406 I'd want it for SPL but at the same time.. it ain't that complicated to need it.. (when demoing) subs get smelly, turn it down.. if they get smelly fast, recheck your tune🤷🏿♂️

meade916 Post a video showing the right procedure? We all could learn how to use the DD-1+. I’ve been using DD1 for years.
If tou set gain with an 0db recording you prob will not see klipping but the best way would be to check with all sources you will use in you system. Even your phone blutooth etc.
I think the best thing to do here is set your eq and crossovers at moderate volume to your musical taste, leave bass boost off and act like it doesn't exist, THEN hook up the dd1 and set your gains. I can see the point of this video. I'm not partial to either party here, but imperfect tools made by imperfect humans are never going to be 100% fail proof. Use your head a little and you should be fine.
That's exactly what a gets from this video...
This comment section is sad
says you, delicious salt is delicious.
@@buddykiller same I love this comment section
LOL "use your brain" the best distortion detector! When I can actually afford to get an o scope, I will get one :) for now, the Ear FTW!
what needs to come into mind is amplifier overhead, people like to think "1000W RMS subwoofer = 1000W RMS amp", the problem comes in when you set gains to not clip, if you set the gain with a 0db signal (which almost no studio recordings are that high) you won't get close to getting full potential out of your subwoofer, having amplifier overhead (say 1000W subwoofer 2000W amp) will be able to get full subwoofer potential and not clip when set to a 0db signal, what i would do is figure out the voltage needed for 1000W of power at the subwoofer impedance and see what the voltage is of your amp (with overhead) max unclipped at a 0db signal, and if it is higher then back the gain off until you are say 10% above the voltage needed for 1000W (use the formula V = SQRT(P*R)) that way you will be always close to getting full subwoofer potential and never clip
But the LED said it's impossible to clip AND making the most power, and total system balance between mids and subs don't matter! /sarcasm
@@EMFAudio and the amount they charge for these DD1s is absurd, ive been wanting to build and document a similar device on youtube but just havent gotten around to it yet, i think i could do it for around $20-$30 of parts
@@wow1022 The frustrating part is that you are more than likely not coming at this from a product manufacturer perspective. The manufacturer has to make money and lots to pay for the cost to build the item, pay taxes, hold inventory, make a living, pay employees, retirement, and also enough to pay for research into the next thing. Yes, there is profit but usually only when the quantity is very high which is usually after a lot of time. How much profit do you think is in that oscilloscope he uses or the batteries on the bench.
The reason you get voltage when the knob is in lane is that its creating a constant resistance rather than variable like a speakers do
I post similar comment as last time:
DD1 works
O'scope works
Regardless of what you use to set your gains (including old school "by ear"), unless you always listen to the same track, output will vary based on source. And, setting your gains correctly doesn't eliminate the possibility of clipping the source or amp, and many don't realize an amp can clip (with gains perfect) when voltage drops and destroy speakers.
Long video with a lot of information.
This comment is for both guys. I know you guys have beef with each other, and you feel it brings brand awareness to others. But intentionally trying to do harm to another only shows who you are as a person. And while I was considering your product and recently at your website comparing yours to another product, understand the lack of product going against someone that has just about the market cornered for many products, the lack of what I wanted along with your ability to show who you are as a person not only lost my sale, but I won't recommend your product to anyone. And for Steve, I hope you read this, because while I've watched many of your videos, and loved your products, and you should recognize some of my comments as well. This is really disappointing how much you don't care about your customers. I thought you did, but instead of educating and offering the truth to those in question, you go off cussing at them as if they are being the a$$ to you. No, they are customers, potential customers, and also tell others how they are treated. And obviously you could care less since you make the money anyways, it just sucks to see who you truly are and how much you don't have the right to bash on anyone else when you are far worse. I get it, we aren't your homies, nor will we be. And those big guys have your back. But think of where you could be with better customer service. Remember who the little guys are as well, we just might make a better product some day with better customer service. But you two can battle it out like elementary school children, I'll get my wife's car done from a company with better customer service. I'm only spending $10,000 but I'll design my own. And $3,700 for two 12's hand built in the US how I ask for them to match the car how I want is worth it to me. I could have spent it with you guys, but obviously I mean nothing to either. I'm just a keyboard guy on TH-cam with a wife he wants to make happy.

My modus from snap-on does everything this thing does and will communicate with all models of car/truck and I can watch EMF while doing so😏
So on my deck ( pioneer DEH-9600bx...ish) I've noticed if I adjust my SLA it will adjust the amp of the deck separate of the volume. Watching it on the scope I can adjust the max volume of my head unit . So if I clip at say @45 out of 60 I can turn the head unit down to allow it to run cleaner at a higher voltage .....I don't know if I'm understanding correctly but I know , cus I used my eyeballs , watching a o scope, that's what it does. I am not sure that's what it's for. I can set that separate for different formats ....example ,,
When I play Pandora I need to add more SLA ( +2 ) to compensate for the crap signal but when I listen to CD I run -1 SLA , sub volume and less or more cross over. So am I just doing things wrong or did I accidentally do something right?
I do final adjust with my ear. Mr EMF you can't tell people to use common sense these days, I mean one, it's rare and two there is not a app for common sense.😐
We just got a zues at the shop ND no lie it'll do all that and some, but the $12k price tag doesn't justify it really lmao
I think the SLA uses the CD source as baseline, and you adjust the other sources from that

Piezo tweeters work well for making a simple detector. Like 6 bucks
Dso with custom firmware works nice too.
Just got a much nicer handheld oscope though so I'll just stick to that
As much as I love car audio and change things up these dd1s and all that do too little for me to want one.
no it really doesn't. There are a lot more factors involved.
@@meade916 like what?
Like his pocket.
using a nice low frequency sine wave you can go from dead silence to an annoying buzz at clipping because piezos are essentially high pass filters (impedance goes way up at low frequencies) and our amps are for putting out low frequency and crossed over. so the hpf filters the low frequency sine wave out. then turn up the gain and as the high frequency square wave is created by the clipping youll hear it. can do the same with regular tweeters and simple crossovers.
ive looked at the results with an oscope looks good can set a usable soft clip this way as well if you want.
theres already videos out there doing this using a small speaker and a cap along with oscilloscope readings and sound to back it all up
heres one th-cam.com/video/lAn4WGny-gE/w-d-xo.html
pretty sure tfade has one as well. along with a lot of others.
Geeze use my brain. That's why to hard.😂
Clipping and distortion are 2 different terms. The SMD meter shows distortion and voltage, the oscilloscope shows the signal.
Question: if setting up properly as you did, but then play a song that has deep or bass boosted notes, could that bad boosted song introduce clipping even though there wasn't clipping when initially setting up?
Yes, that's the inherent problem with using a tool to set the gain. At the end of the day, your ear is the best tool to adjust things in real time.
yes all day long
I was waiting to see the real test.

Thanks why it good to have a radio that you could change each source output so you don't clip basically you will go with the one that you use the most if you use Bluetooth set your gain on Bluetooth. Then from there adjust the other sources through the radio
