Make your own distortion detector for under $25 - Tech Stuff Tuesday 

That was a good Mafia front.

@@alphaomega8373 CIRCUIT CITY!! :D YES!!

Poppa T I worked at RadioShack for 5 years during the early 2000’s and you can’t imagine just how right your comment is. One time we had a “regional loss prevention specialist” come to our store because of some “possible employee thefts”, me and my manager literally stole and sold close to $15k worth of shit on eBay EACH and they could never prove any of it. Well, the loss prevention guy continually used two phrases, nothing for nothing and forget about it but he said them like a, you guessed it, fucking New York mobster. The guy was decked out in yellow gold and diamond jewelry, including an Italian horn pendant, a very not cheap Armani suit, slicked back perfectly black hair and so much VERY CHEAP cologne that it would choke an asthmatic to death. He threatened us in his only special round about way. He didn’t get a fucking thing out of us but we sure as fuck robbed that store blind 🤣🤣

@@erictheboringone5292 so you are one of the many reasons they dont exist anymore. Not sure why your prowd to admit being a thief, but yeah thanks for that ya douch

@@michaelparsons3188 you're, proud, and douche spelling and grammar matter.

Outstanding!

Shit bro I’m an atheist but I gotta say that it sounds like you’re doing gods work if you’re out there teaching the youth the way of the bass head. My hats off to you sir. You should be nominated and given sainthood.

Well building a system will give them something constructive to do. It will also give them an opportunity to use their heads with applying some math in the real world, and learn how to use some tools as they work with wood and other materials. Hopefully it will inspire a few to stay off the streets, and the trappings thereby. We're gonna call the club Beatin the Streets.

@@russellburgan9023 mad props to you it'll also give them something that will spark the interests so maybe a few of them will say I wanna have my own car audio system so will inspire them to work hard so they can build ther own and then one day I hope they stop by and show off ther accomplishment which will help inspire some of the next generation to repeat what the other accomplished

@@mikemccabe7124 right on. Some say car audio is frivolous. I suppose a person could go overboard... nah lol. But yeah, a hobby is a goal to work towards. Accomplishing things, goals, gives confidence surely. I hope that it has the desired effect.

@@russellburgan9023 I definitely think you have a good idea to build off of.. where I live I owned a few car audio stores and I spent alot of my time helping those that wanted beyond ther budget but couldn't afford it so I would help them by giving them side jobs around my shops and I aided them in installing everything that way they'd learn to do it on ther own and that was the best feeling to see that I helped them learn something

Make no mistake, the O-scope is still a better option and gives you more info, BUT this is a good option if you wouldn't use it often or you simply don't have it.

After watching his oscope video a few weeks ago I purchased the liumy oscope on Amazon for around $80 and it works great and it is decently priced

This method also does lows, all you hear is the distortion, none of the signal. Some might say this method is better at lows than highs.

Pretty easy to do, right?!

@@EMFAudio yeah...pretty straight forward...thanks man...learn new things everyday...👍

A single step guide on getting lung cancer

Black Grand National Richard Clark? Yeah, THAT guy knew some stuff.👍

@@PURESOUND4 yes he's still around his knowledge made my head hurt good luck with you channel I learned a couple of things 👍👍

That's living the Taramps life.

Yes you can. There will be no difference between measuring directly at the RCA outputs of the headunit or at the RCA's you have running out of the headunit. Pull all RCA cables from the amp then do your test.

That's what one of the two parts of this is for.

@@EMFAudio so using female plugs will be fine?

That is something I'll look into at some point. I've got other things taking a priority.

EMF Audio Ok I saw barevids doing something similar with a small speaker hooked up to the amps output via a small capacitor

DerTechnikKanal i also saw a video with a piezo tweeter.

@@tubestoned yea i think a piezo would be thre easies way cause it clearly makes clipping audible

DerTechnikKanal no it actually doesn’t. It doesn’t detect it as solidly as this does. Besides that the tweeter with the capacitor isn’t capable of testing for distortion I. Your head unit. As cheap as these are and as easy as they are to build, this is the way to go. And yes I’ve tried out barevids way he should in that video. Besides, if you’re trying to used the tweeter and cap to set up your sub amp you are hoping you have the right cap to capture the sound of the signal that clipping distortion creates. It’s not as simple as he made it look.

Yes, a tighter tolerance would be OK.

People respond to [empty] threats different ways.

Barevids showed how to do this awhile back as well with a speaker and a resistor

I haven't tried headphones but I suspect there would not be enough output signal to power headphones. If there is, it would have to be something like cheap earbuds.

Reduction of signal strength down to the clippy parts.

It's a Velleman, I don't recall the model, it's about 15 years old.

The dummy load makes more or less current, not voltage. In practice, as long as you're using the amp at or above lowest recommended impedance you'll clip without a load before you do with. If you're operating below recommended impedance, it will clip sooner. If you're experiencing otherwise, it's because the source volume is different, which is also why you should always use your ears.

@@EMFAudio I think that you will find that once you start drawing current through a load, you will get voltage sag especially if the power supply isn't up to the task or you happen to have a bad ground. But you will clip much earlier with a load than without! Could potentially be a future video test? The more that you load down the amplifier, the sooner it happens! It gets much worse with some amplifiers so I usually recommend to stick to the better brands unless you understand the amplifier at it's circuit level which I have no problems with. I still remember my first car amplifier, a Realistic 50W x 2 back in 1987... Subwoofers weren't even a real thing back then but I had two 6x9 speakers with their tweeters removed in an isobaric fourth order bandpass enclosure, I very well knew what was possible from way back then! I may be over 50 today but the boy inside of me is still there and keeps me young at heart! Man! If only we had Google and the tools we have today way back then...

You'd go out of the LC7i. Just start with it all the way down and you'll find the HU clipping point that way.

@@EMFAudio so turn the LC7i all the way down and hook this up to the rca port or where I plug the speaker wires into?

I feel like I've touched on that in many videos but never really went into detail because I assumed it was too basic to cover. I may be overestimating what people know.

I'd have to try it. The speaker being amplified and still not being extremely loud means the signal is quite weak, but that may be ample for ear buds.

You got an old junk TV or radio laying around somewhere? Collect them from that along with the speaker. If not you can always find shit like that sitting next to the curb for trash pick up in residential areas. Have fun!!

Remember, the speaker is amplified, that's a key point to this.

EMF Audio a Bluetooth speaker whit 3.5mm input should work?

@@juanpestrada5231bdndjkdn Yes, it should.

Many have asked so I will test that.

I listed everything using in the video, and the document where it originated from which has some of that list.

I mentioned in my setting gain with an o-scope video the potential concerns with those.

It's a Velleman, but I've had it for around 15 years so I'm sure it's not made anymore.

@@EMFAudio thanks I'll eBay dive and see what I dig up

@@EMFAudio by the way...What's it gonna take to get a Banhammer 12?? Nobody has stock and I want to use it in my build...v1 or v2

@@mattpierce4143 V1's are long gone, v2's are pre-order. So it will take a pre-order to get one.

@@EMFAudio I understand a date can't be committed yet, but are we looking at a month or a year until shipment on the preorder? TS parameters similar to v1?

The camcorder I use is about 10 years old, I've got some DSLR's and 4 Go-Pro's I use for other things but at the end of the day, the amount of time it takes with additional editing and setup isn't worth it for the view counts the videos get.

EMF ?

@@PURESOUND4 how good are they? I listen to a wide range of music and how much abuse can it take.

@@killer32620 EMF Lowballers are rated at 750w rms, a step up from that are the EMF Banhammers rated at 3000w rms, but those might be out of stock right now.

@@PURESOUND4 only running a fosgate 1200rms amp

@@killer32620 I've seen videos of Lowballers taking double their rms rating. That would be my choice.

He was actually referring to Rockford Fosgate.

@@Hertzsogood219 He gave credit to RF for the design. The jab was taking someone's idea, and marketing it as your own.

Powered headphones would work, and easier to hear the noise as well. I might actually try it with my noise cancelling headphones and see how it acts.

The specs are the specs for a reason, the percentage and wattage are critical points.

@@EMFAudio I've looked everywhere locally and online I can only find 1/8 Watt 5% or 1/8 Watt 1%

@@74midwestbass74 The giant bulk pack I spoke of I got from Amazon I think, maybe Ebay. That's the only way I could find them, in a bulk pack with others.

THANKS SO MUCH!!!

The wattage you can go higher but not lower, the tolerance you can go tighter but not looser.

I believe the limitation is 100 volts, so it's not so much wattage as rail voltage. 100 volts @ 4 ohms isn't the same power as 100 volts @ 2 ohms isn't the same power as 100 volts @ 1 ohm.

I'd question the resolution of the display on it which may potentially lead to inaccuracies.

It also doesn't work as well. Build both and circle back in comments.

Nah gangsta it don’t work that simply. Gotta have some circuitry in there that can detect the actual change in signal and allow current to flow when that change occurs.

I’m right there with you but not as bad. I have tinnitus from the Polish Army doing a controlled det on 350lbs of HME. They did the det less than 500m from the tiny COP they lived on. It was nuts. They gave a 5 minute warning over their PA and then 45 seconds later were getting showered with dirt, rocks and shrapnel and no one could hear a thing except that awful WEEEEEEEEEEEEEEEEEEEEEEEEEEE sound that you hear after some Polish numb nuts try to blow up their own COP...

@@erictheboringone5292 I have tinnitus in my left ear. Good times though, nothing like blowing shit up!
