Throughout history, it has never been possible to design a great sounding amplifier - no design exists that promises to deliver the ultimate in sound quality. No precision, component choice, gold plating or bling can bring about that which sound we seek - only talent can do that.

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.
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.
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
Hypnotising in some stages of production. I once hand-equipped and soldered 60 small boards (300 solder points) with discrete parts/sockets by hand, which was quite a balancing act to stay concentrated. Doing something like the stages in the video would drive me mad after 1 week (though, I guess, the people get rotated between certain stages).
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..👏👏👏👍👍👍
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.
@@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
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.
@@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.)
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.

Thank you; one point of concern is the glue used to stick the power supply capacitors to the circuit board before soldering them on. If you watch videos by many people who repair audio amplifiers then you will hear them complain that over time the adhesive becomes not only corrosive but also conductive. This leads to the destruction of adjacent connections and short circuits around the capacitors.
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.

Why isn't anyone in this company wearing ESD protective equipment and/or gloves?? I've worked in a PCB factory like this as a test engineer, if I went in the factory floor without ESD shoes, jacket and gloves, they would have my head! You cannot ensure quality without ESD protection that prevents damage to the device and without workers who handle hundreds of boards per day wearing gloves because you might leave fingerprints on the product (for certain ultra sensitive applications the fingerprints might actually affect performance, but it's mostly to ensure general cleanliness).
first of all these are dirt cheap amps , they are made be loud not be high fidelity and there is no components used in a class d amp that is esd sensitive . all of the parts can take kv's of esd without failure.
That is why production in China is so cheap. Safety of people doesn't matter, so why spend the money on it. I have seen videos of a chemical plant that had similar working conditions, so this one isn't even that bad.
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.
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!
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 :)
Evidence that China is able to produce very high quality products!
I take it you have enjoyed listening to this amp then?
Watching this video in the morning, What an amazing meditation!
Very nice video sister
Wounderful commitment for quality control and dedicated professionalism. Hats off.
thank you.
BM AUDIO DF4 1800. 4 x 1800W into 8ohm. That's quite the amp!!!

tu as raison
Really cool. A lot of older machines and techniques, but still looks very organized and efficient.
thank you.
So… this morning I built a bird house.
Pretty proud of it.
To watch this being built is incredible.
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
The circuit board building machines are mind blowing

Indeed, I had problem with this glue when repairing my old amplifier. I think now they switch to epoxy glue which last a lot longer.
what kind of beast is that? the amount of caps and the size xD
Woooow!!!! my first time seeing this
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.
