BM AUDIO DF4 1800. 4 x 1800W into 8ohm. That's quite the amp!!!
Really cool. A lot of older machines and techniques, but still looks very organized and efficient.
thank you.
Its amazing how much work goes into making something like this, it may not look much from the outside, but take off the cover, and a world of wonders is inside. But the hard work people, (No matter what country is was made in) have to do to make something like this... . I originally thought the PCB boards were compleatly done by computers and machines, even assembly...The way these things are made is simply amazing.. But no..Then at the end of its use, it gets discarded or thrown in landfill.
Amps like that have a lot of large components which are wire-ended. If you did a low power circuit like a computer board you could possibly manage nearly all SMD. I understand most of the work then is setting the machine up for a production run.
As an amplifier designer , I can understand you so well.
wardfiction..."Then at the end of its use, it gets discarded or thrown in landfill" OR it ends up like on eBay and people like me collectors and hoarders bid and buy the retro tech and fill up our storage with these seperates...i even swap and change them out to let other Amplifiers and Cassette decks have a turn
Old SMT machines from the 90' but still gets the job done.
So impressed seeing this amazing job electronic engineering is what I can't stop hurting more to that these entire implemention is quite expertises❤
Excellent factory workers!!😊👏👍
yea but the guy @ 10:06 over torqueing and destroying the threads of that fastener.
Very hard work but amazing.Man's hand and mind are truly the genius creation of GOD.Respect to these hardworking workers.Respect to all the working class of the Planet..👏👏👏👍👍👍
경의를 표하고 박수를 보냅니다.👏👏👏👏👏👍👍👍👍👍🍀
Nice production process. Amplifiers look decent. Might
Wounderful commitment for quality control and dedicated professionalism. Hats off.
thank you.
Watching this video in the morning, What an amazing meditation!
Perfection, even to putting the tape on the box👌
Непривычно смотреть что все сотрудники без униформы, у всех произвольная одежда. А это показывает культуру пооизводства
надо учесть, что ещё 30-40 лет назад весь Китай занимался только выращиванием риса и чая, а теперь они снабжают весь мир своей продукцией, качество продукции - разное, но уровень некоторых технологий достаточно высокий. Особенно интересно сочетание нескольких технологических эпох на одном предприятии.
чувствуется совок говной пахнет
Id like tp see a video of manufacturing pioneer amllifiers from the late 70s into the kid 80s
Google it amazing whats out there .
Al fin encontré el chino que le pone pegamento a los electrolíticos... Muy buen video !!!
😆🤣🤣🤣
شكراً لكم على هذه الصناعة
Great work 👏 😮
To be frank , those are some really solidly made looking amps. Lovely modular design lots of care taken in assembly and what looks like a well organised production line. What's their rms output because with that amount of capacitance on the rails they look like they have some power behind them.
Unless the power supply is switchmode, the transformer looks a little undersized for large current swings, but otherwise looks half decent.
if you are lucky this amplifier may work for 10years instad of blowing up after few years of daily service.@@josephchristman578
To się nazywa profesjonalizm na piątkę 👌 Pozdrawiam
Vida longa a China por nos proporcionar tecnologias a preço justo, aqui no Brasil só temos lixo, mas graças ao Paraguai conseguimos esses amplificadores, hoje meu som é todo com amplificadores Chineses, e o governo aqui do Brasil que chore por que não dou um centavo a produtos Brasileiros muito menos imposto de 100%
tu as raison
Thank you for leaving out the music!
최고의 제품.
I like the way that vibrating tables are used to simulate road use to identify dry joins etc.. I've used these very 4 channel amps ( 2 for 8 way on stage monitors) and they were loud , reliable and saved a lot of space. We used them hard for over 2 years ( 4 gigs a week) before one channel developed an oscillating fault. Easily repaired though. Great product.
haha if it fails driving monitors It would not last till the end of techno festival driving main P.A.
@@fran0085 It ran faultlessly for 2 years doing four to five gigs a week. It only cost a few hundred pounds new. If that is not value for money tell me what is ?
well benefits are high power output from very lightweight amplifier, but every digital amp we ever had simply stopper working properly after some time because I rent sound for 80% techno/trance events in Croatia, and digital amps dont like power from generators in combination with that type of load electronic music requires. Now I make my own analog amplifiers but not because I want to play with electronics. These series are specially designed[overengineered] for this workload and they really do the job but weight 30kg/amp@@johnallen8680
From the small chip makers & components to the motherboard build to final assembly amazing production
So… this morning I built a bird house. Pretty proud of it. To watch this being built is incredible.
I wish I had a job like this wow💚💛🧡
BM Audio and Lab Audio amplifiers, also "bm audio df4 1800" is the model.. 4 channels 1800Watts.. For those of us with curiosity!!
I COULD ALMOST SWEAR IT SAID Lab Gruppen DF4-1800
@@blacknoob6666 I also vote lab gruppen. inside is almost identical but without dsp and stuff, only power amplifier.
Very impressive ..thank you !
This is an amplifier factory from Korea or China or Thailand, the sound is amazing, we are from Indonesia
This is an amplifier factory from Japan or Taiwan, please reply
its from guangdong, china.@@mjono1467
YES > I remember the 'technical drop test' in servicing, but this place has it all down pat. So interesting.
Creative video, thank you :)
Sou técnico a 40 anos e fico impressionado com tanta tecnologia 😮👏
Good audio amp. manufacturer 👍
Yes the rack case looks really good, if you remove and throw avay all electronics they put inside you can make very good amplifier into this case.
Looks like a very powerful amplifier for the PA market in Australia/New Zealand.
Thank you very much for coming all the way to our factory to shoot and edit such a beautiful video This is our factory If you are interested, please contact me
Evidence that China is able to produce very high quality products!
Very nice video sister
I love it good 👍
Minh cũng là thợ điện tử.ước gì được vào công ty này làm.cho thoả đam mê
Excelente vídeo
It's great to see videos like this.amazing
beautiful video of beautiful amps!!!❤❤❤🥰🥰👏👏💋❤️💋🤓
The stuffing machine and it's speed, accuracy, and scanning of parts is absolutely awesome.
And it’s not particularly fast. Those are, according to other commenters, 30 year old pick and place (SMD) machines. Newer machines, especially used with smaller components, are way, way faster. As for the through-hole components, that speed had already been achieved by the 1970s at the latest.
@@tookitogo yeah but the old smt machines are for older components ie the Fat capacitors the newer one are designed for miniature components
@@StealthGT40 Every SMD pick and place machine will be slower with large components than with small ones. Nonetheless, modern PNP machines are FAR faster than the ones shown here, for any given component. The fact that we often use smaller components now only adds to the final placing speed.
@@tookitogo There is a serious g-force with a fast machine. I think you need to bolt the thing down, like far worse than poorly loaded washing machine!
@@Andrew-rc3vh That‘s an interesting question! Bolting or weighing down is one way, but another would be some kind of counterweight system. As long as the forces cancel each other out, it‘ll theoretically be stable. (Industrial washers, and a handful of very high end domestic models, do active load balancing by pumping water in and out of chambers built into the wash basket to exactly balance the laundry itself. The domestic models have only had this for maybe a decade, but in the industrial models it’s been around since at least the 1980s, possibly much longer.)
The circuit board building machines are mind blowing
Very good!!!
Quero estar ai um dia... Amo este trabalho ❤️....
Good 👍
Imprecinante 😮
Awesome superb fantastic
Wow amazing technology ❤
How can I make my country to mass produce just like these asian guys. I really like these things alot❤
by a out of use SMT line it will set u back about 50k, but u need process engineers to install it and make u the programs for this
@@valerius39 Thanks alot but seems its quite good long journey but the benefits are impressive.
@@happymatekenya394indeed a long journey bro
you start making analog amps by hand, with toroidal psu, no smd components inside, you just need to find very good schematic and it will probably work longer than you will be alive.
Made in any country , this is amazing .Thank you for this wonderful video .( amplifier body is so appealing too)
Likely a design copy from a LAB GRUPPEN, which is a well known western brand. This Chinese brand appears to have even partly stolen the name: LAB GREEN. Watch closely in the video, you can spot it on multiple occasions. If you look for LAB GRUPPEN FP10000Q, you can easily spot they've even copied the internal design to a high degree.
Indeed@@Sixta16
if you are lucky this amplifier may work for 10years instead of blowing up after few years of daily service.@@Sixta16
China is the King of Manufacturing...no doubt
Yes they really are King of manufacturing worst crap and selling it as good product...no doubt
Que Marca es la que se trabaja se ven potentes y felicito a todos los trabajadores por se eccelente trabajo
Ребята вы заметили, осциллографы все аналоговые )
wow amazing production
amplinya keren banget puas liat komponennya sangat bagus bagus keren habis , semoga laris manis di seluruh dunia yang suka musik dengan power dasat dan bas suara nya
what kind of beast is that? the amount of caps and the size xD
really nice products !!
Thật tuyệt vời ❤
Salam kenal Dari palembang 🙏🏾🙏🏾
good Job Man ❤💯👍🙏
Man made machine, machine made work easy and fast.
Woooow!!!! my first time seeing this
👍 Une chaîne de montage remarquable de professionnalisme ! Félicitations ! 👌👏
Good Video 👍❤🎉
they are working very good and priciesly. I like power supply. How can I get one of them?
What do you like about this power supply and how do you know that "they are working very good and priciesly.", if you ask how to get one of them it means you doesnt have this amp for at least few years, so you know nothing about it.
La verdad lejos de la realidad como trabajan .........felicitaciones
superb technology,
Excellent
Amazing
Interesting to see the test technician using a US made multimeter.
Most Flukes are made in China or Malaysia. Some identical models are made in USA, as required by military procurement regulations. Essentially identical - except for the price!
Many testing requirements specifically require using Fluke in final testing measurements.
Nice
Good amazing
How much does this amplifier cost and who should buy it? ❤
very nice injineering

Yo Armo potencias echisas y sería un reee sueño trabajar en un lugar Así de fábricas Profesional !
Nice video
New subscriber always watching yourvideo❤ many learning❤
AWESOME 😊
Great video but to complete the story would be a video on the machines they used being manufactured.
They have a semiautomatic printer using stencils with squeegee rolling paste into the apertures , than next process is SMD components placed by old SMT machines Fuji model CP, than they go trough reflow machine to liquefy the solder paste and than turn it into solid cositor joint uniting pcb pad with component, than I see use a old Panasonic PTH machine to introduce into PCB the trough hole components than place manually into a wave soldering machine that has molten cositor touching underside of pcb, the terminal of the components to fuse it with the pcb , after that they have a inspection machine or AOI that has predefined program that checks presence of components , misalign and check for other manufacturing defects probably, than they test the finish product :)
Whats the name of the Amplifier ???
Nice poses
good video
Fest geklopft ist halb zerstört... Das ist eine robuste Qualitätskontrolle!
what was that mystery ferrite transformer 5.58, also is it class D design.
මම කැමතියි මික්සර් එකක් එක්ක තියෙන ඇම්ප්ලිෆර් එකකට transister audio live sound i like
Impressive.
What is that vibration test done in the process?
I guess... It's necessary bcs incase of any particle or tiny object/residue in the chassis assembly might be a thread to the system doing so to avoid short circuit making sure everything is tied in place.💯
@@Kelvinbrook_101 There are two of them. One to probably find soldering faults and loose contacts and one to remove residues from production.
Вот она,реальная экономика 😮😮😮!!👍👍💰💰💰💰💰💰
порнуха для инженера ☺ отдельное спасибо за то что показали как маунтеры заряжают, нигде обычно это не показывают
Как они припаивают компоненты сами прилипают?
@@user-jr4cx4lr7e маунтер на клей их садит. на кждой деталюъе есть маленькая капля. и за счет пасты тоже держатся
@@user-qv4fo6xp2w а дальше я думал в печь суют и олово плавится равномерно везде.
@@user-jr4cx4lr7e да , дальше в печь пайка по термопрофилю
