- Just a stripdown with no rebuild of the behringer mx 8000a. And a crazy way to desolder components using a hot air paint stripper.
Teardown starts at 05:10 . . . Desoldering starts at 10:30

piece of music used is from Holst the planets suite (mercury) played by me on synthesizers and does not violate any copyrights. - Věda a technologie
I used to own one of these and used it for a decade or so - pretty solid device. After this video, I see potential parts for a new patchbay and some fun meters for whatever the heck I want! I'm on the hunt for a broken mixer!
I used to have one of these in my basement studio for quite some years. It's actually a near replica of a Mackie 24/8. Quite alright value for money. Unfortunately, Behringer used inferior parts everywhere, so the sound of the Mackie and the knockoff are worlds apart. Just subscribed to your channel, btw. Interesting stuff here! Keep it up.
Hi Markus. I have just seen this Video for the first time and it was really really great. I have just recently purchased one of these in good condition with everything working except the tape returns mix B Channel Group 41 - 48 which are not passing audio through to board so will have to take it apart eventually to do some repairs so it was great and very helpfull seeing this video of internals from the Mx8000 Thank you
I have a lot of love for those old desks, but the lack of automation and scene recall does mean that you are limited to working on one project at a time with them, and the amount of cabling required to hook it them up fully is crazy! A very interesting teardown, and I got the impression that was about as dignified an ending as something like that could hope to have :-)
+Eddy Deegan Thanks Eddy. Its spirit will live on in the next life and hopefully I will try and make use of its donated parts to save the life of other electronic gear waiting for transplants. :-)
Love the heat gun/paint stripper idea. Worked nice!
+Sysex|Studio Yes I must try holding the board level so the components face downward next time.
I tear down and clean my MX 9000 every 5 years. Seeing that grease penned "B" inspires me to sheild another power cable each time.
A fascinating look inside a mixer board. Now, if you can track down a vintage radio station mixer from the 50s. I actually used one as a board op for a local AM station here, back in the 80s. The board dated back to the 50s. Had 7, or 8 rotary pots, and three analog needle type meters. Also worked with the ones made in the 80s, to. :) Thanks for posting this.
+ThomasGrillo Thanks Thomas. I removed one of those old mixers from a small studio years ago, I think it was an allen & heath and it had proper wooden sides on it, a thing of beauty but sadly it went to the recycling yard.
I don't have salvaged things in boxes, just 1 big box, with a front door and roof on it :)
+slider2732 hehe, basement box here.
+slider2732 LOL I love that one. My place is like that also. the bathroom is the only room that does not have a keyboard in it and thats only because the steam from the shower may damage it.
+markusfuller Sounds like my previous place XD
Many thanks for another very interesting video, Markus!
Don't worry about the video length too much, I think you have a very good feeling for the optimum lengths each time. You will not be able to please all people anyway!
I like the mindset to recycle things, which is also a key thought in this video.
The trick with the LEDs really surprised me... seems like that "there is no business like show business" also applies to the equipment used, haha. Many thanks, David
+David Mood Thank You David. Its always a difficult thing trying to make something from lots of video recording. I do cut out many pieces but I think they are boring or long pieces that are better removed so as to make the video flow from beginning to end and try my best to make it interesting. It takes ages to edit the video but if just one person gets some entertainment or useful information from the video then I am happy I have shared something. Many thanks from Markus
cool because i have the behringer sx4882. i record to a fostex d2424lv and this mixer works nicely with it and my outboard gear. how cool that you are able to take this apart! that mixer is a good one. mimics the mackie console!
+Marc Abernathy Hi Marc. yes it could have been used for a few years yet but i simply do not have the space for it or need any more channels than my qu-16 already handles. I hope i manage to make use of some of the components that way it has lived on after death.
Ive de-soldered like that before but had the board horizontal with all the components facing down, just gave the board a couple knocks while doing it. Worked wonders on high component count boards, tested a lot of the components afterwards and had no real issues.
+Kyle Rhaged Hi Kyle I agree with you. I mentioned the very same thing in a comment to someone else. trouble is I only had that one Vice grip for the board at the time. but next time i will try it horizontal.
Wow great video. Im a bit late in catching this one . Hahaha loved the heat gun, you made it look so easy . I may consider this tactic for the future . I definitly agree with your view on salvaging . Although ive regularly used Maplins they dont stock everything and hold very small qauntities of stock in compinents in store .
To use the hot air gun is not daft at all. I have done this when I was a kid, a lot. It was my biggest source of components for building stuff and I am still using some of them today. I even repaired music gear (DeltaLabs delay) with salvaged components of an old Commodore computer, in this case the 16kx1 DRAM. All salvaged like this. They usually surive that without any damage. I am surprised that this idea was new to you. I really like that you take the effort to give the components a second life in another unit or as a hobby project. Oh and at my work there is a SMD workplace, also equipped with a hot air gun. I just had to use it last week.
+Chip Guy Vids Hi I have the smaller SMD hot air gun but I was not expecting anything to survive from the use of the paint stripper. thats why I had never tried it before. all I need to do now is find the Air scoop attachments that came with it so i can direct the heat in a more precise way and hopefully a new way (for me) to collect components.
+markusfuller Yes that is a good idea. I got a smaller nozzle that just sticks on the top (about 1cm diameter) and one of these, they are good for DIL40 and longer SUB-D & IDC connectors: www.bosch-pt.com/de/de/accocs/image/product/prodimg/5315/181665.jpg/?maxwidth=250&maxheight=250
There are about 3 or 4 nozzles for this paint stripper somewhere but my house is like a Tardis. small but lots of gear inside. trouble is it is very difficult to find things.
This makes a nice digital vs. analog comparison video ( for Behringer consoles) combined with your other mixing desk video :P
Love the heatgun idea!
hi Mark hope that wright i am Tony i set here watch the whole process taking apart the mixing board I found interesting always have found lectronic interesting anyway but it does shine a light on how exciting our life's are lol use the pant striper was a stroke of It was a good idea any way have a good day TLDukes
Tony Dukes Thanks Tony, im pleased you liked the video :-)
Fantastic video! Love your stuff, fascinating. Do you produce music as well as repair electronics, because you seem to have a lot of knowledge about music and equipment as well as components and how the circuts work. All the best to you!
Markus: tip on rapid-desoldering: I use a paint remover heating gun and the components just fall off the PCB after heating it up for a bit of time.
as soon as I typed this, your video arrived at the part with the paint stripper :-)
Bart Coninckx Hi Bart. yes I am doing that now with one of those bosch paint strippers. very handy and so many components to reuse
What I did after being able to acquire a mass of old PCBs is turn them upside down, heat the solderside with a paint stripper and just tapped lightly with a hammer on the PCB, while holding the PCB above a bucket. easiest way to get a bunch of components in a very short time. the only parts not being really happy with this were IC sockets, those would bend slightly.
It hurt me a little to watch that MX be taken apart for the last time, kind of like seeing a ship being decommissioned. At least I got to see someone use a melta gun on a circuit board!
+Michael Smith I hope some of its parts will be used in future projects and repairs.
ugh. I want it! I need to buy one.
Very cool! Also, I like the Sonic the Hedgehog 2 cart in the background :)
+Steven Morris Thank You
+markusfuller To do a mass de-solder on a scrap board..... Just use a standard heat gun and pre-heat the back of the board on low first and crank it on high and tap the board with something while continuing to heat and everything should start falling off! ;-)....... I hope this trick will save you a lot of time and save precious space as well :-).....
Hi. Yes I will certainly try that one out soon. I have lost my jet nozzles and need to find them so i can better direct the hot air onto the board. Many thanks from Markus
markusfuller NP :-D
Eu gostaria de saber se você ainda tem as peças desse mixer, eu tenho um igual que poderia usar algumas partes!
Hello Markus.............. Great video! I enjoy it! I really appreciate the depth you went into, your eco friendly attitude for parts, and will definately try your souped up hair dryer technique. What a ingenius way to get parts off a striaght circuit board!.............. Thanks for the wisdom!
Question? I know it has been quite a while since you posted this video, but any chance you would be willing to part with the Meter Bridge for this board?
I always Injoy watching your channel.
Thank you for that.
P.s
nice to see that you are a Wallace and Gromit fan, maybe you can do a space craft to the moon tear down, or build a moving mechanical trolley fridge(with skis) Cheers😊
+lachopakapura sharon lerner's channel Yes Im a massive Wallace & Gromit fan. someone called me Gromit on the market one day several years ago and I had no idea what they were talking about until they explained who Gromit was and what he did.
Great video. Thanks!
I've got 3 of those Behringher mixers. 1 is a parts donor. i have 2 meter bridges. The Behringher was an exact copy of a better built Mackie desk. Court case etc.
Mackie owners were buying the Behringher meter bridges as the Behringher was £120 compared to Mackie £330 for their bridge. There's a market for that bridge btw.
thanks for the paint stripper tip. quality suggestion.
Thanks CyborgTR808, I was originally going to try and make spectrum analyser from it but its too complex. I may just put it up for sale not you told me it could be worth something. Much appreciated. best wishes from Markus
+markusfuller
no worries Marcus. I enjoy your videos. You appear to have taken apart most of my studio haha :-)
BTW... if you want a good laugh .. you'll find on the internet that 25kg PSU for the desk was built with inherent failure in the design. Capacitors are mismatched and chips blow. Causes desk to go into red light mode with piercing test tone blaring. Read up on it. its typical Behringer garbage :-)
I've had my fun with repair visits to my engineer.
+markusfuller
& the current going rate in UK eBay for bridge is about 130 plus carriage on top. wrap it well. those end plates wings snap off as its brittle alloy.
peace!
& if you repair the psu .. its going rate is about £100 on ebay.
I have the PSU. It works fine. may just ebay that . Thanks for that idea :-)
I love the spectrum analyzer idea!
+Elsif Hi Elsif. Thats on my mind, I must look into how that could be made as it would make the thing useful in my music room and look pretty cool too.
+markusfuller yeah ! Build a 1/3 Octave Spectrum Analyzer.
+markusfuller Look up the analog vocoder circuit from "Music From Outer Space". It has the array of bandpass filters that you need.
thanks I will do that.
TheSlowGrowth Music From Outer Space is a bottom-less source of synth info (synfo?)
Hey, just found this video while looking for information about what horrors I'll find in our MX9000 mixing console; hopefully it's just dodgy solder joints on those ribbon connectors and some flux and good solder will fix 'er. Channel 9 has no gain, Channel 13 only has gain when the input reaches a certain level, and Channel 17 is completely unresponsive. Also, I need to look into why Mix B is unbalanced (other than cheap) and if I can reliably balance it without coloring the audio toooo bad, as I'd like to use it as a stereo aux send.
I recently discovered a metallic harmonic ringing noise when I am switching the meterbridge to 'channel'. I have searched the internet and found some people with that same issue. It can also be stopped by pulling out one of the multi-connector cables from the desk to the meterbridge.
Some people hinted at the power supply as possible origin of the noise. Where would you look for it, Markus?
I have MX9000 bt Don't have the power supply! What can i do for it?
Ah Amstrad, an old mate used to work for Currys and still does, I remember going in and having a look at the fake separates HiFi with my eye on a Pioneer real separates and laughing at the Amstrad stuff with their faders that used to pull a piece of coloured paper past a hole in the plastic panel simulating yellow through orange to red or something like that to represent fader position. Allan sugar has a lot to answer for.
I have an old Yamaha Clavinova where one of the keys doesn't work unless one of the keys directly next to it is pressed. I was cleaning the contacts on the keyboard when my screwdriver fell on one one of the dozens of diodes on the underside of the contact board. The diode and solder points look fine, just one of the leads was slightly bent. Could a damaged diode cause such a problem?
+hasso0n Yes I would certainly think about replacing that diode. they allwork together making the keys you press send the voltages into a sort of Matrix which is figured out by the diodes. do you have a multimeter?. if so check the diodes close by and see if you get the same reading from the dodgy one. remember they sort of conduct one way but not the other. apologies if you already know this I just dont know about your electronics knowledge.
hi i have this deck iy's got A AND B mixer yes you are right the led part is the best part to resell bob
Hi Markus, thanks for your very entertaining and informative videos. May I ask what breadboard you're using in this video?
Frank Hi Frank, I think this breadboard came from maplins electronics but you can buy them from many sources, the brand is called K&H products.
Thanks!
Hi Markus yet another very interesting and well done video ! Love the use of the heat gun why did I not think of that doh! I did this a couple of years ago with some old organ and a scrap mixer pcb's but I used a blow torch so was a bit to hot and melted some bits lol but like other comments it sad to see a nice bit of kit being scrapped, when I have collected old organs free to good home on gumtree I can't tell some people what I do with them lol ps great work on the Holst/Tomita backing track have you posted the complete track online ?
Regards Steve
+SequencerSynth Hello I have not finished the Holst/Planets yet. theres still a long way to go but I am doing every part myself and lots of multitracking. but I need more time as I love making music and the planets suite is well embedded into my memory from childhood. I will put it onto youtube and download for free somewhere when its complete (but it will take a while). Many thanks form markus
wow that bargraf is realy realy nice
+robot797 Yes I like the bargraph and hope to make something useful from it.
+markusfuller You would need to built a lot of bandpass filters to make a spectrum analyzer out of that string of LM339 meters.
I know Im thinking i may be wishing for a simple life but this is going to take a lot of circuitry.
This looks like Behringers version of the Mackie 24:8:2, even down to the "Mix B" functions, and having to buy the meter bridge separately. I use the Mackie regularly, and have done a few repairs to it and even the board layout is the same internally. They were always copying stuff, making their own version of the Pioneer DJM Mixers for example.
+Jon Simmons (Neffers) Yes its a pity it had to be stripped down but technology moves forward and my allen & heath qu-16 mixer is a third of the weight & size with effects etc and usb stream & multitrack recording to hard disk etc etc. dont get me wrong behringer is made down to a price but I find some of their gear quite good for the price.
Music Group have 'recently' made the acquisition of TC Group too (Tannoy, Lab Gruppen, Lake, TC Electronics, TC Helicon and TC Applied Technologies), it's quite a nest of companies for Behringer to be amongst. Lets hope they don't 'frankenstein' too many products and continue to make viable budget yet desirable ones.
Thanks Marcus. Always enjoy. You've listened to Isao Tomita? Probably the best electronic interpretations of classical music ever recorded.
M
+Mark G Yes I have several Tomita albums here some i have not heard in years but I know them in my head.
Hello from finland. i take parts also mx8000. i use hot air blower and hit hammer the circuit board so many components falls at once. And sorry my bad english
I have heard that the MX8000 is a copy of the Mackie 24-8-2 console. Now I wonder: Which opamps did Mackie use? What are the differences between both consoles?
Hi Markus,
Just out of interest, are any of the pots, switches or sliders in any way serviceable with some switch cleaner etc? I have a MX3282a (smaller but similar age and design) which has problematic routing switches and a couple of noisy sliders - other than that still a good console.
Hello MrHarmonicminor, the sliders are easily serviceable but a lot of the switches are sealed units and would take a bit more work to try and fix them. It would be easier if you could source new ones and replace them rather than dismantle them as they have tiny springs latches etc inside.
Hi everyone.im pulling my hair out.lol.I have a 2002 12rq unity peavey mixer.It has developed anoise such as,when i plug it in to power i hear a click assumming it is a small contactor and then it immediately starts humming.so anyway my delimma is that i have every piece of nut ,knob there is on top preparing to disassemble the top so i can get inside.Can you possibly tell me if they're clips or ther fastener that is preventing the sides from coming apart to further disassembly.Thanx in advance.
Hey do you have any tips for getting through stripped screw heads? I purchased a very dirty Tascam M-512 the other day, works great, but has some scratchyness here and there, so I thought to get into it and get out what gunk I can. So, I was trying to get into it, and of course, one of the first screws I go for is stripped.
+Terror Van Hi I have had this problem myself and do not have the answer. I just work with small pliers if I can get a grip on the head or have even used a dremel to cut a slot for a straight screwdriver to fit. other than that I do not think there is an easy way.
+Terror Van If you can reach the head (not countersunk), then I use this type of pliers: www.precisehandtools.com/screw-pliers/engineer-pz-58-neji-saurus-gt-multi-purpose-pliers-with-screw-extractor-jaws
And if it's not an flat-blade screw, I also use left-hand drill bits
The paint stripper was inspired ! :-)
Will you ever get you hands on some Elektron gear? I own a Monomachine and would really like to see its innards :)
I like your shirt Mark
A cheap desoldering tool that works! I'll have to get me one of those because every time I try to desolder anything with a soldering iron it's a disaster, and none of those stupid vacuum bulbs / pens work worth a damn.
Hello Markus,
Great video as always and I like that this video was longer than normal, so for me personally you may make more of that longer video's. But I know, more time is more work to edit and render so no problem when you don't have the time for it.
With lots of respect for Dave but your teardown was more interesting and the way you eplain how things work are a lot better. But Dave isn't into the music electronics so maybe that's also the difference and that you know where you are talking about.
Looking forward to the next one and greetings from Roel ( RoelTyros ).
+RoelTyros Hello Roel. Its a strange subject getting the video lengths just right, some people complained about video number 70 being too long and not getting to the point instantly and theres the others that can seem too short. I dont think there is any magic number in minutes that can please everybody so I just make the video then edit it trying to pull out any long pauses and some are longer than others but I do not stick to a rule of length of time. I think this last video was just about right for the subject it contained. But thankyou very much for letting me know as it is something I occasionally think about and wonder what people think about the length. Best wishes from Markus
+markusfuller Don't waste too much time thinking about how long videos should be. I think you're doing it just right. I guess it's not so much about the total time (viewers can pause and go on later if it's too long). It's way more important to cut out long pauses and avoid repeating the same thing again and again (as happens often on the EEVblog).
Maybe this is a good point to thank you for the effort you put into making these videos! I really enjoy watching! Please keep it up, it's fantastic!
markusfuller For me personally I it doesn't bother not really to me how long a video is, and when it is to long that it is so simple to pause it. So even it is a short one than it is absolutely no problem for me or a longer one with some things repeated is also no problem.
Most I like about your video's is also the subject and as you know I am also just like Organaut an musician. And than a look inside of all that equipment is very interesting, and also tips how to repair.
But also the way you explain is more understandable for also people like me, just hobbyist and not a professional with electronics. Somebody like Dave of the EEVblog is sometimes to technical and than it gets boring after a time. With lots of respect for Dave of course, but for the simple hobbyist sometimes a bit to complicated.
Anyway, go further like the way you make your video's, and that typical English way of making humor is great !! I am crazy about old series like Fawlty Towers and Are you being served haha.
Many thanx and greetings from Roel !
Thank You Roel. That was interesting to read your comment. Yes I will always try and let the video's take as long as they take but try and cut away boring or non interesting parts. some people want instant video all over in under 2 minutes but I cannot explain anything that way and I think a few minutes to talk about the thing i am about to take apart or repair can be interesting to some people and those that want just the end result can skip forward.
Why watching a teardown? it gives me hype to make something.
and I always do.
Now I have to salvage some reverse logarithmic pots.
+Jetset Willy I love salvaging parts. I have filing cabinet drawers (the thin drawer type) and they are choc full of parts. some from my childhood (and that was a long time ago). but every now and then someone needs a specific old transistor and occasionally I have it.
I modified a FuzzFace yesterday, glad that dozens of AC128 ,Oc72(glass) laying in the container.
I guess we both have minor OCD.
I have some of those somewhere. I scraped the paint of some of them once to make light sensitive switches. that was many years ago.
Can I buy a couple of the spare knobs off you for a reasonable price? I'm missing some on my Eurodesk.
Hello Roy. sure what do you require ?. ps maybe better to send a private message through facebook so I have your address to post to. my facebook name is markusfuller.
Hi. May I ask you a question about this desk please ?
Hello I no longer have this desk and it was a long time ago when i made this video but yes please do ask any question you like and i will try my best to answer. best wishes.
got one of these
Very good. I do the same here ;)
+J Cesarsound Excellent, I love recycling old components.
“BOO-t’ns...” - 🤣. “JACK-sockets...” - 🤣 🤣 (ReDUMBdant!)
Use a pc instead?
+Snufkin224 I use mac & Pc and digital desk also. sometimes its nice to have hands on fader control rather than mouse but occasionally i just use a mouse for many music projects.
Hello Marcus,
Good job sometimes ago l requested if l can get some electronics components/ parts for korg ,Rolland,Kurzweil and other workstations and synthesizer. Am also into repairs,let me know if its possible to be of help so l can make arrangement for necessary payments. Thanks. Mike.
+Ajetunmobi Mike A Ogooluwa Thank You Mike I too have difficulties finding some parts and I can spend hours on google trying to find things sometimes. the companies do not always want to send out replacement parts which can be kind of irritating. but you just have to try and now and again some of them will help out. as Korg did when I requires a replacement touchscreen.
Dear Markus
Thanks so much for your prompt response.
We have so many of this Korg, Rolland,Kurzweil etc. Of different brands/models that need one parts or the other,well as you have said we will keep trying, in case you can be of help in any way in future kindly informed. Thanks.
is that dog in the background gromit?
What's the point ?
Why destroying my heart is bleeding there was maybe only dirt inside .
My good God, please do not make a church organ your next teardown :-)
Nice 10/10
+Matt Shultz LOL I only have a small work area so don't worry. but it would make an interesting video though ?.
+markusfuller You get the jokes, sweet ! I thought I went to far with this one ........
Cheers
hi ! 3 weeks without a video, are you ok??
+Arnaud Bevilacqua Hi Arnaud, I have been away working from home for a while and only got back home a few days ago. so Will make another video as soon as I can get the chance. Many thanks :-)
+markusfuller thank you
Totally off topic: you have a GNOME!!
Hi That was not mine. I was looking at it for a friend.
No No No i could never bring myself to do this .Fix it and move it on to someone who could use it .I learn nothing from the video a butcher could have done the same job i loved all your other videos i really did but any more like this one no i just don't understand the point.
Yeah, I get it. I'm off buying a grey original mx 8000 tomorrow for 130 euro's, revised 3 years ago, incl. meterbridge.
But also I understand Markus' view. The value sum of all the parts he can collect out of one mx8000 is also bigger than having to buy seperate parts online, with extra shipping costs and waiting time. I have 3 mackie 8 bus mixers here (32, 24 and 16.8), of which one is going to get sacrificed to fix the other two. The 16.8 will be saved for sure, incl meterbridge, I really like the size. Not sure if I want to save the 32 or the 24. Also depends on how many good parts are left from the 32 and 24 after the 16.8 is in top condition, so bigger chance the 24.8 wil make it and I will modify the 32.8 casing as a double 19 inch rack holder or something. But If I can save the 32.8, this will have priority. Bigger number is always better, right :p ?
I got the 32.8 for 175 euro's, the 24.8 for 60 euro's (left masterchannel is defective, also lots of sticky buttons and scrappy faders) and the 16.8 with meterbridge for 210 euro's.
interesting
+David Chandler Thank You David
Why not just clean up the noisy pots and switches and then sell it? Perfectly good board - you didn't need to kill it. :(
minute 6 before it even gets on topic
I found this a bit hard to watch to be honest.
+Neil Robinson Yes it was a bit sad for the mixer but one day its donated parts may help another item live on.
+markusfuller I kinda cringed when you went full scissors on the cabling, but you are right :3
+DrummingEvil I guess these old analogue desks have had there day.
+markusfuller Possibly another Behringer mixer. I had a 32 channel that lasted about 8 years then died. My tech couldn't fix it (would have cost too much, so I bought a new Yamaha) so pretty much the same thing happened to it.
yes shame these things do not last very long. I do not think I have ever had a mixer last more than 4 years without some problems starting.
Markus, is there a role for some one doing what you have done? It would only be viable for developing nations to do this because of their low wages. There must be billions of pounds binned every year.
+Anoop Sahal I think we should do this more often and try and reuse things instead of burning and burying so much waste. I know some materials are broken down and reused but I think if we try then we could do a little bit more.
still somewhat of a shame
