  • In this video I show you the best tool to set your amp gain. The camera shows the difference between the SMD distortion detectors and the Liumy Oscilloscope.
    Many thanks to Steve Meade for the gift. No doubt this is the best way to set your amp gain, but it is to expensive for some people. Get your test equipment here*:

      When you adjust the gain for distortion either for the smd or multimeter, did you move the crossover frequency for the lpf all the way up. My polk audio has a freq of 50hz-500hz on the knob and on hpf it's 20hz-400hz. Need to adjust my gain this weekend and while I know how to get the target voltage I don't know what to do to the frequency before I start moving the gain knob to PROPERLY reach the targeted voltage

    nice video! out of all that, the MOST important thing you talked about was how everything in the chain starting from the beginning matters. I see a lot of lame video's on YT where someone is trying to "teach" people how to set gains with an O-scope and they are doing it completely wrong. "Just turn up the gain till you see (or hear) clipping" is not how you set gains. Head unit (or L.O.C if tapping in), DSP, crossovers etc, everything BEFORE the amps needs to be known first or it is all out the window. Also there is gain overlaps. Something completely ignored by these so called youtube "teachers". I have always told people, USE AN OSCOPE first. Learn it. Love it. USE IT RIGHT. Then get a DD-1 (for more accurate and simple results) once you feel like you are ready. It's the same process. (The DD-1+ Plus is a little different). But the standard DD-1 uses the same exact technique you would use if you had a scope. So no matter which one you choose, just do it correctly. Or turn all knobs to the right and jam on till you smell that smell. There is a right way and LOTS of wrong ways to do it. Thanks for the video it was a good watch :) Appreciate ya for that!

    No lie, the distortion detector is more than double what I am willing to pay for it..

    I use an oscilloscope with fft as that allows me to see the actual wave form and the harmonics being produced. Where I live a two channel oscilloscope with this function is a third of the price of one SMD device and can be used to read many other signals for other projects. You can add a current probe and do math to get real time power and impedance numbers.

      I think it's unfair too ues ones product and mass produced these units to sell at a very expensive price for what is a simple light the smd dd1 is good for what i does but Steve should be ashamed for over pricing a piece of equipment that only has a light no screen and advised everyone that they need he's product so he can continue too live out his expensive life style. I bought one because i too fell into the track . I repair and install and modified car audio and im a electrician as my job i been installing car audio since i was 12 and since then i love car audio i remember the real and fun reason the days of car audio and electronics and it's why i made my hobbie too learn it i will simply say dont believe the hype i uesd the tool that cost me up too 200 plus shipping with a cd and a blinking light knowed as the smd dd1 and i returned it the next day reset my gains in my system and too my ears i was more pleased with my sound again i noticed that my gains were a little lower than with tool . The car audio and sales is all about making money now . And selling cheap products made and deigned with cheap parts what does matter if it says made in usa with cheap parts from China. People stop making these con artists rich they over price there gear and boasting there worth all over the internet. Car audio was never about money it was about music and joy and products that were way better than todays junk for half the cost i should know i been repairing amps and electronics since i was 17 in fact my amps are modified and are old school Components cause i know how well they outperform todays way over priced junk back in the day you did get what you payed for.

    This was a good watch. The distortion issue is one that I never had considered or taken much thought into before, so it was really interesting to see that demonstrated. Just due to being the type who likes to tinker, see how things work in depth, and get the absolute best value, I'll probably always have a love for scopes. But this video was great in how it presented and educated about the SMD tools, I have quite a bit more respect for the engineering behind those tools now.
    That compressor behavior is something I think I've only seen on pro audio gear before (with my very limited experience with pro stuff), so it was really interesting to see that on that little premade car enclosure. It makes me wonder how common that circuitry is on lower end gear, or if maybe it was just a once in a blue moon thing that some engineer thought was a good idea on that particular system.
    Anyways I really appreciate your content man, it's the thing I like seeing in the audio, and really any, community. We shouldn't get so caught up in what's "better" and "worse". Instead we should be educating each other on how to make the best of the gear we do have. That and of course, trying to stick to the facts of the situation is always the way to go. There's always more to learn. Thanks.

    Hopefully more and more manufacturers will start including clip indicators on their products. Obviously we still need to check head unit outputs for distortion along with any other gear we put in the signal chain. But, simple clip lights on all amps would be enormously helpful.

    I too am like you, am in my 30s getting back into car audio, i use to "install" in my younger days, looking back im not super proud lol. Now that I'm older and better funded which leads to better tools and materials I can actually do professional level install, so far its just been doing my own stuff, I might take on side work in the future, but now that I have proper shop tools, and the knowledge and experience now to do it right, plus the technology and pricing is so much better these days, additionally guys like Justin and Steve sharing info, I love the hobby all over again. I have been wanting to get a few of the SMD products for a while, I think they are really cool, I just can't justify their cost at the moment for as much as I would use them, currently I'm using the O scope and DMM method, which is light years beyond how I use to set stuff lol. Thanks again Justin and Steve.

    I sprung for a DD-1 about six months ago and I'm happy I did. I began my journey into car audio with a MTX1501D bought off a local Facebook group and have slowly continued to climb up to where I'm now running 6000 watts on strapped amps and backing it with lithium and a high output alternator. As you get into the more powerful and higher quality gear it becomes too expensive to risk doing it incorrectly. I've noticed my gain walks a little every few months from the vibration and a DD-1 is fast and simple enough that I can re-tune in a parking lot when something doesn't sound right.
    I definitely agree that for someone just starting out the SMD tools may be a little too out of reach and a cheaper alternative may be needed...just as long as it is done right. For those bitten by the bug and constantly wanting more though, you can't go wrong with the SMD line.

    Great video and very informative, the only thing that comes to mind in regards to needing a multimeter to set gain is in a situation lets say where you have an amp that can put out 2 or 3 times the subwoofers rated power. You would have to have a multi-meter or an oscope so you can turn the gain up to where the sub is rated at. If a DD1 is used you can only see where the amp starts clipping but at that point the power that the sub is rated at would be double or tripled. I cant see a reason to buy a DD1 and or 1 or 2 of the other SMD audio tuning devices unless you own a shop and time is a factor as the DD1 can speed up setting the amp if it can be done that way vs. using an oscope. If somebody does car audio as a hobby and setting there amp once or twice a $100 oscope is more than enough to do the job.

    I know I’m super late to this, but great video and info, as usual! I use a Liumy scope in conjunction with a Fluke DMM and the tweeter version of the DD-1 that Sam had made a video of. Works great if you have the time and space to set up and test everything or the space to haul it around like I did when my friends needed equipment installed (apparently because I’m a big DIY audio hobbyist and all about learning, I’m the audio guru friend😂). I have limited space in my car so I finally made the choice to pick up a DD-1. No more Packouts crowding my little Focus just set up an amp! It’s great to have a vast selection of tools in your arsenal, even if you don’t use them. What’s that saying about needing it and not having it?? Yeah, that applies to a lot of stuff😂
    However, as a DIY and a bit of a perfectionist, I do love buying the proper tools to do an install correctly, even if they’re the cheaper ones (usually temporarily) and I have spent a LOT of money on doing just that…the next couple of tools on my list to upgrade are the PT9A+ and an RTA & mic setup👌🏻 even though this is mostly all for just slowly upgrading my personal audio installs over time😅

I just recently bought gear to have a nice system in my old Dakota and I just wanted the DD-1 to set my gain. It worked great and now I can either resell the DD-1 and possibly make a profit and have set gains, or just keep it and have it for life. I'm keeping mine and will set gains for friends if needed and have fun with it. As a former "pro" I only wished they had this back in my time. Great video as always.

    I use a mini oscilloscope and a multimeter to find the maximum my amp can go (5 chs) then I rely on my ears. I know up to what point I can raise it, it's just a matter of preference thereafter. I have noticed my amp mono section needs to be tuned in that way but the 4 ch output has a Max of 30v just like you've gone through.

      25hz, One test you can also do when settings gains and tuning in conjunction with your ears, what I do is use my Oscilloscope as a visual guide of what my amps are doing with my sub/bass/mid bass/midrange/mid high/brightness frequencies and what ones clip for adjustments. Whatever clips, or is wasted energy and can be filtered out, or EQ’ed.

    When I was younger I did it by ear 👂 but now that I have some education with electrical and using O-Scopes it's a basic understanding of how AC works and what many people forget is different frequencies have different wave forms and time periods with a good O-scope you can measure multiple things at once I believe you can't do that with The DD1? I really don't believe it's a bad tool at all but the cost per usage is what I look at when buying a tool to do a job, If I bought a dd1 it's only for testing and tuning amplifiers with an oscope it has many usagages not just car amplifiers so would I buy one nope 🙅 I will stick to what I was trained on

    Good video. I have the original liumy. The backlight screen has gone out, but still works. I recently bought Dean's irta2, which I love to see the signal. I switch out between audio control, audison, my d'amore mono block and old skool Phoenix gold( original ti series) amps on a regular basis. Yes, the audio control has distortion detection built in, and the audison software has clip lights too. However, I still, after 30+ years in car audio, have a hard time with 'gain over lap'. I understand the reasoning why, but I need a tool to help with that. So, now it's a matter of dd1, or dd1+? I figure , if I'm going to buy these amps( which I doubt I'll ever stop doing) , then I need the right equipment to tune it, otherwise I've wasted my $$$ on the gear.

    At 10:00 when the distortion light comes on, but there's no clipping. Keep in mind that there's different types of distortion than just clipping. You can see the sine wave looks a bit crooked, not a perfect wave. That is the distortion that's being detected. It's pretty hard to see 1% distortion of a sine wave. A few percent higher and it's easier to see.

    My stereo OCDs caused me to get both, The DD-1 works and does exactly what you want it to. You're kinda paying more money for the product that is easier to use without having to think. If you're on a budget, The O scope is more than adequate, you just have to know what you're looking at (like your examples). I like that the O scope gives you voltage at the same time.
    Ears can work.. You can for sure hear exactly when the wave clips with your ear, the tone changes. You just need a way to attenuate the signal so you don't blow your ears out. Example: find where the head unit clips by turning amp gain all the way down. you'll hear it change.

    I know I know. Everyone has their tool they like to use. But let me tell ya. I got the DD-1, and used it with the Cheap gear I was testing. My god man. It was a gift from beyond! I was able to find every bit of CRAP gear and identify almost every little bit of distortion or noise in my system or gear that just did not make the cut and I was able to get this very inexpensive gear and find out its weaknesses and even fix it.
    I was even able to determine the weak spots in my signal chain for my head unit
    same with the digital signal processor I was using.
    the thing is, I don't just use one tool I use as many as I can to go ahead and get a good reference just like somebody at audiosciencereview uses a very expensive machine to go ahead and get results and measurements from gear.
    but all that does is give you a baseline working in a lab environment which in our car audio world doesn't quite work that way.
    but thanks to his tools, Steve made literally made my car audio experience not only inexpensive but I was able to get the absolute maximum with the equipment I was using.
    the final judge is always going to be you and your ears. But for me? I use as many tools as possible to track down any sources of noise in my signal path and chain.
    my final piece of advice is don't worry about the best way worry about the most thorough away and you will always have your audio Nirvana

    @DIY Audio Guy I love your videos and had a few questions boggling my mind any answers or advice is much appreciated:) So I set my gains using a Oscilloscope and the wave was clean up to 40 volts on a skar rp.800d:) My first question is that I feel 40 volts is quite high for a 800 watt rms at 1 ohm amp so am I not understanding something correctly here? My second question is I realized by watching the soundwave that when I set my crossovers (subsonic=26hz/lpf=100hz) while playing the same 40hz-5db tone the voltage drops from the 40 volts to 25 volts. I'm just a little lost on why my voltage is changing so some clarification would be great cause that's quite the voltage drop. Last question, is it not good to set your gain with crossovers already set? I see everybody set crossovers after gain but I'm just curious if you can set crossovers then gain as long as you never touch the crossovers after setting the gain? Cause in my mind it makes sense that that would maximize voltage/performance:) I believe that with 25 volts after crossovers I'm only getting 625rms wattage out of the amp so if it needs boosted a bit I will:) thanks for any advice or clarification:) I also have the smd dd-1 and the smd clips at the same point as my Ocsilloscope so I believe everything is accurate:)

    • @DIYAudioGuy
      @DIYAudioGuy  2 ปีที่แล้ว

      The crossover works by cutting voltage, the slope follows log10. So it is not a wall, it is a gradual roll off that gets steeper. What you're seeing is the top of that gradual roll-off.
      And yes, that does seem like a lot of volts for an 800 watt amplifier.

    have you tried using a piezo tweeter or tweeter with built in crossover/ capacitor to set gains vs o scope or dd1

    I love the SMD tools.
    Especially the AMM-1. It shows you exactly what's happening in YOUR system..esp impedance rise. And seeing your actual power is awesome.

      You can do most of that with a good clamp meter, but the AMM1 is designed with audio in mind.

    Question? How do we check the signal going to your speakers once we set head unit EQ, dsp settings etc.

    • @DIYAudioGuy
      @DIYAudioGuy  ปีที่แล้ว +1

      You should not need to, and remember when setting up the equalizer you cut instead of boost. You only boost a frequency if there's no other option.

      @@DIYAudioGuyQuestion? After you check your head unit for clean signal, flat eq, no bass boost etc. then make sure amp signal is clean, dsp signal clean I never see anyone show how the signal is after you set eq to your liking.

    Very nice video again , i own the dd combo, but if i'm not mistaking when you read the instructions , thay say to play 40/1000hz tone when you try to find the max volum of your head unit , but when you set your amp they say somethinf about -5/-10 db 40 hz tone. So what s the right way ? 40 hz 0db , or -5/-10 ?

    I might have posted this before, I know you were using the Dayton DSP. I found it will only take 1.5v in and only 2.3v out.. So use that information how you will. I've got an audiocontrol on the way. The helix is what I really want.

    • @DIYAudioGuy

      I remember seeing the post, not sure if I replied. I like the 408 but it is an entry-level DSP. I'm hoping to upgrade mine sometime in the near future!

    5:49 I think the noise if it's the output of the amp, is not going to be filtered by the crossover at all. That is noise that the subwoofer will be seeing and playing. But that's still probably so quiet and high in frequency you won't ever notice it over the noise of the "wub wub" it's making. If it's above 10kHz then I doubt you'd ever hear it on a subwoofer ever.
    Thanks to this video I might hold off on getting a cheap o-scope as if it isn't telling me the whole story and could leave distortion on the table then It's not what I need. This also helps me feel like I'm actually accurate assuming my amp (NU3000DSP) is limited to 24/25v per channel before distortion jumps to very audible. Might not be clipping, but sounds very bad past that.

    • @DIYAudioGuy
      @DIYAudioGuy  2 ปีที่แล้ว +1

      Slowing the footage down really helped. I think it was interesting that neither the scope nor the AMM1 showed clipping on that cheap amplifier.

    • @JoshM7
      @JoshM7 2 ปีที่แล้ว

      @@DIYAudioGuy Yeah. Curious what it takes on the scope to show the distortion. Like would you need a better scope or more practice with it to see it. Or what other device would it take to make it easy to detect the 1% distortion.
      Maybe some sort of RTA you can clamp onto the output of the amp that shows the frequencies and the harmonics. I think harmonics 40dB below the fundamental tone is 1% and 20dB below is 10% distortion. There's probably a device that could do that, but is it cheaper than the SMD tool? I need to look into this more now.

    So I've I stalled an jvc kwm745 head unit paired with an audison sr5.600. I have looked at the out put of the head unit using an oscilloscope there no cliping at full voltage . Although I have sent the gain to matched the pre out
    I was thinking is there any reason why I can match it it to the speakers, which are audison rated to 100w rms @ 2ohm. Or set the gain as close to speaker max before oscilloscope shows cliping.
    What are ur thoughts
