Mark repairs a 12 channel mixing desk, with a few missing outputs and no effects working. Also tries to fix a fault thats not there! Clearly, Mend It Mark is not a DJ....
On a philosophical level - if you have this positive attitude and approach to electronics and existence in general, life is so much easier. Being far more prone to sulking and taking a more negative stance I really envy you. And I second everyone who comments that you spread light and laughter. Thank you sir, keep repairing different electronic devices and post your work and your loveable personality here!
Writing from Germany. Besides your knowledge and your pristine equipment, its heartwarming to watch your humor and your always positive approach. That´s real fun to watch. Great!
I am not sure at what point in the video you are talking about, but the mixer does have stereo outputs on it. Just because it has a jack does not make it an input jack.
@@neutrodyne No duh a mixer would have output jacks! How else would you use it? That's seriously what you took away from that particular comment? The one with several likes already on it indicating others knew what I was talking about? WTF?! Actually watch the video. He was looking for an output signal on a set of inputs for a few moments and was very confused. It was good cause for a chuckle during an otherwise very clean repair. ...Or maybe you didn't understand what you were seeing as you watched the video? I've been collecting pro and home audio gear most of my life but thanks for being condescending to someone who could be just as experienced as you if not moreso. I guess I'll just turn to my several shelves and stands full of high-end headphones, speakers, DACs, equalizers, pre-amps, phono-pres, turntables, CD players, headphone amps, and speaker amps and tell them daddy must not know what an output jack is. Being condescended to sucks. Especially when it's by someone who clearly has no idea what's going on. Delete your comment.
@@neutrodyne To put it simply, Mark was confused since the "stereo" were aligned with the "MON OUT" (specifically under AUX1 OUT & FX-BUS OUT). So Mark, like most of us watching, thought that stereo-1 & stereo-2 were a STEREO OUTPUTs only to find out that those were stereo INPUTS and proceeds making a face which was hilarious! It's a label error. Should have labelled "STEREO-1 IN & STEREO-2 IN" to avoid confusion.
A punter knocked a full pint of beer on my powered mixing desk (Dynacord Powermate 600) years ago. The sound of fizzling components over the PA was both terrifying and epic at the same time! ;-)
Need more patience than there are knobs on that mixer. It's when you put them back together and the fault comes back, that's the killer. Another great video.
As a sound operator of many, many years, it's easy to forget sometimes that all the knobs, dials and faders don't just intuitively make sense to anyone who walks up to a desk. Also, if you show 6 guys the same board, you'll probably see 8 ways to use it due to differences in preferred workflow. So overall, good job on finding your way through, even if it was a little painful to watch up front! ;)
I do relate to this to a certain level. When I showed my grandparents my surround system for the first time, they were asking me what a speaker was hahaha
HAHAHA. Well I think I figured out 9 ways. I did a open mic coffeehouse, each performer would get two songs and then we would take a break and have a featured artist at the end for the second half. They started with a 12ch =/- peavey that had developed a fault in the digital processor which also took out the main mix momentarily to temporarily. I also worked at another other church which had a 32 channel of the same model which did the same thing that's now sitting in my basement one day I will investigate. They finally (Church property) replaced it with a good old fashion analog new sound craft. Never quite did figure out how the effects worked Foley. it was a similar model mixer and In the end at that location I just stopped using most of the mixers features and only use the preamps to feed into my own mixer an xr18, so much easier and I had a preset for that venue to bring everything up into the default state that I like to start in. After patching cables ( I converted a snake to a insert direct out snake ) all I had to do was check the gain, stereo return and master level, I would then twiddle the gains a little depending on the acts but mostly do the mixing and affects outboard. There was nothing wrong with that mixer other than it occasionally had other users which meant rechecking just about every channel before and of course it was mounted in the most ridiculous of locations. Standing in front of the mixer just slightly off-center of a 20 x 50-75' converted Pavilion staring down the barrel per se with the band right center on the long side and the mixer 8x8 feet from the short side wall corner literally a half wall from the end Center door pathway in this weird Half wall cubicle were things like to get stashed.
How many soundguys does it take to set up a mic stand ??? TEN(10) ... One to set the stand up and the other nine telling him how much better they could of done it and how bad of a job he did . LOL...LOL.
I have a Makie 1604 VLZ with an intermittent channel 1. I've had it apart and cleaned push switches, faders, pots etc, re-seated cables, which only solved the issue for a day or two. Never thought of checking the resistor, the layout inside looks almost identical to the Soundcraft board. Will give it another look.... thanks for the idea!
As it's only one channel, I'd put money on it being the Insert jack on that channel. If the insert is bunged up enough, it acts as though a connector is plugged in, effectively muting the channel. Get into the insert with some contact cleaner and a jack plug and give it a really good agitation.
Fantastic video .. Thanks for sharing Mark! Our Church sound board is a Soundcraft EFX22 - and it's main fader (slider) plastic shaft is broken - I was planning to replace it .. but boy I'm afraid it is very time consuming process dismantling the console just to get to the fader ... smh.. I love the idea of using the oscilloscope and frequency generation ... I’d be plugging in microphone and speakers :)
Everyone commenting on if this guy is an engineer,you bet he is.This guy could hold his own in any electronic company or environment. He is next level. He choses to work for himself.
Here I am, watching Mark doing some fancy hot air soldering and thinking why ... why am I not doing this myself - enough stuff here to fix too 🤫 Ah well, at least the mixing desk I received had an easy repair: "channels 1 and 2 have low volume" was fixed easily by turning up the gain pots 🤭
Last time I watched someone tackle a mixer it was a cheap brand and it had a problem with bad capacitors, apart from having to pull the mixer apart, he decided to replace every single electrolytic capacitor and there was a lot of them and I decided right there and then that I would refuse to repair a mixer.... You couldn't pay me enough to work on one! You are definitely a better person than me LoL 🤣.... Great work!
Beware of the microphone DIN inputs. Ensure that the phantom power is switched off or you could put 48 vdc into the output of your sig gen ! Later in the video I see you are aware of this but I will leave this here as some may not be aware. So pleased that you got the twelve channel mixer working. A few years back I took on a Behringer Eurodesk SX4882. It only won insofar as time spent repairing it, never again though. In total 27 hours spread over five days and a repair bill of just under £360. Beer & mixing desks do not go well together !
Totally feel for you mate. I have a eurodesk 3282....32 channels with 8 subs. Bought off of fleabay with a noisey output. Turned out to be dry solder joints on the master faders. I'm still flakey on how long it took, but it was bloody ages. Literly a bucket full of pot knobs, screws etc. It's due a service (deep cleaning), so it's time to beg the repair tech gods for some patience....and plenty of mugs of tea and maybe a beer of two aswell 😁
As an audio engineer and DJ, I've learnt to swerve Behringer kit. Items might cost less than many other big brands... but they aren't very robust. And so second-hand items are just a disaster waiting to happen!
They're not DIN. Those are XLRs, sometimes called Cannons (the original manufacturer. How is the phantom power on a microphone input going to end up on an output ? You're not meant to use them as high level inputs (although it can work but risks early clipping). There's a jack input as well which is 20dB less sensitive.
You can imagine James Hetfield barking at big Mick to get the mixer working. " But James, I've got a million knobs to pull off". "Hey man what you do in your free time is your business". 😂
My workshop is BARELY able to work on SMD... so I seek out OLD SCHOOL mixers to fix. I did have a 2001 Yamaha with a bad SMD op amp, and I did fix it, with patience and a magnifier. I'm glad you can keep a cheery attitude while doing it. I'm sure you're hoping for a 6 month break before seeing another of these.
And being a fellow brummy mark is a top bloke and entertained you all the way through the video brilliant. Makes a change for someone pleasant to give such good quality tutorials
I work with these all the time and if this was situated in a certain setting the aux out would be used as monitor. expecially if it was for a band. you could use he aux to give the drummer or lead guitar a different vol level than that of the monitor

@@Username-qx9gk While the generic term "engineer" isn't regulated, there are terms for particular areas of engineering (typically those related to public safety) that are legally restricted in their use. In Canada, for example, a "Professional Engineer" is someone licensed to sign off on things like structural engineering designs and is legally responsible for their safety. In the U.K. I believe the "Chartered Engineer" term is similar.
check out the new A & H stuff they are up there giving the big boys a run for their money. Ah the gl3300 been there! blue TAC and TAC scorpions back in the day
well, this just goes to show how good you really are at your job - it's awesome watching you work these things out - a definite *You Tube Hidden Gem* of a site!
I enjoy your work so much mate! I feels like I am seating by you, ( some times even talking back to you: you better vacuum that metal shavings; or you are placing that upside down!). I would love to take my KX600 Kenwood tape deck to your shop; I know it needs some belt replacement for 24 years now, and you'd find something that could be replaced or touched up. The only problem is that we are in different continents. So... I'll keep watching you repairing a technics deck.
Yeah, I feel you, Channel 11 is wonky on my 24 channel, and I ain't fixing it until there are several more things to fix, because taking it apart is an absolute PITA.
Wohh ! the amount of screws and nuts put into this mixer,looks like they seriously made it for military touring pr sound usage,lol but soundcraft are considered one of the best mixers in sound quality and reliability for instal and pro sound rental companies. and they're quite expensive too.
I am a PA sound man FOH / MONITOR over 40 years, AND have "The ear's" so to speak. Some artist i have done more then years of touring. I notes that at 3:28 The AFL/PFL is active, the meter then off for left and right. John - SOUNDFILL ® I use Martin Audio - Crest Audio amp's Allen Heath and the Lexicon is A-Brand. In the past have 2 MPX- 1 in my FX Rack's.
I really appreciate the camerawork and editing in these vids. And just the general problem solving is top-notch. I watched the vid on the linear turntable earlier. I don't want to spoil it, but you went above-and-beyond on that one. I would have given up far more easily. lol As soon as you mentioned opamps in this mixing desk, I KNEW they would all be NJM5532. It's like the go-to opamp when they don't want to spend too much money. lol To be fair, that opamp sounds OK. It's quite a good bang-per-buck, excuse the pun. I'm only half-way through this vid atm. I'm a bit worried that the voltage rails weren't checked before replacing all the opamps. My guess is that somebody plugged in a cable with 48V Phantom Power (from say one of the XLRs) into those channels, which popped the opamps. Or something a bit more scary, involving mains voltages. lol
Currently working on a behringer xenyx x1204usb Mixer that I bought really cheap with issues on a couple of channels. Hopefully I will be able to fix it soon. Love the editing, camera angles and the sense of humor. Your channel needs more subs.
Nice video, thanks. the symmetrical mix outpit is once again the economy version. Soundcraft loves it. That's not nice. The many buttons and screws are amazing. I once pimped a 24 channel mixer. That was even worse. The potentiometers were still screwed there.
Hi Mark, I have 2 Soundcraft EPM mixers, one a 8 channel and the other a 12 channel. They are very similar except without the FX bit. Both, since 2012, have been reliable so far (that’s me tempting fate). The outputs are “electronically balanced” using the resistors to give the same impedance on each of the balanced connections. I used a similar arrangement for balanced inputs on the interconnecting leads to enable the unbalanced insert points of the mixer to connect to a 24 track digital recorder (I’m only used 8 channels/tracks at the time). There are separate record (input) and playback (output) leads so the insert points can be used as both input to record and output to mix down via the mixer (in analogue) or using digital for computer mixing etc. My mixers are used to record everything from soloists, choirs to an orchestra for live broadcast hospital radio programmes. The only problem is that the phantom power is ALL channels or none, therefore two mixers. I now have phantom blockers and transformer isolated splitters too.
a great video, once more Mark! Watching you going around the PCB fixing and mending things, soldering iron on th eone hand and scope probe on the other has really a suspense movie quality to it!! Keep up!!👍👍👍
WOW, That’s a lot of Screws & Knobs, I found one of those in a Skip while working around the UK a few years back and it worked fine, It was just missing a couple of the Slider Knobs but managed to Sell it on eBay for a tidy sum! 🙂
Good and interesting videos of the equipment and repairs, thanks! I never see anyone ever using that copper de-soldering braid anymore these days. I was surprised to see that people still use those terrible glass fibre pens to clean PCB's - those things were hell on earth, we stopped using them in our factory almost 30 years ago due to the problems the operators got due to the tiny needle like fibres that went into you skin on your hands. God knows what they did to people lungs, a row of 20 ops all using these pens and each bench fitted with a fan to blow the dust from one bench to the next person in front. Then throw in an ultrasonic bath that was using Arklone K, and each op. with a 300ml can of Trich. what a wonderful workplace - No fume extraction, tin lead 60/40 solder, it is a wonder our kids had hands and feet!
Gotta get me an infrared camera. Great video as usual. I've used an 8 channel version of that desk before. Fortunately never had to repair one. What a pig of a thing to pull apart!
I miss the days when you could unplug the module. It was so much easier and quicker to repair. I recently worked on a Peavey 24 Ch. console and it took me quite some time to disassemble it just to replace one Op amp. At least I had access to all of the controls so I could clean them.
This one was a fun, action-packed edition mate! Knobs, nuts, chips n crows flyin round left right & centre! And you discover someone else has been messing with it! Grrr! 🤬! Nevertheless you triumphed in the end. 👍💪💥💯👏 Hey I gotta say mate, your soldering methods are as good as mine, & you're the second person ever to get that recognition!👍 Your photography is such that I see how you leave the soldering iron tip in the solder joint for juuust 1 second after you remove the applied solder from the joint. This gives the flux that short extra second to fully activate & do its job before the heat is removed. I see you doing that Mark. 👍 That's nasa standard mate. I was trying to think of what "naughty" thing someone had done to damage the mixer so extensively, & how power must have be applied to it somehow where it shouldn't have been? Then you mentioned phantom power. D'oh! Of course! That's 48 volts DC, that's supposed to be supplied to the mike via 750 ohm resistors & isolated from the mixer inputs via 47uF capacitors, with 1meg resistors on each of the balanced mike outputs to discharge the capacitors. So yeah, absolutely, a mixup in the wiring to a phantom power mike is exactly the kinda way to get DC power into a mixer where it shouldn't go! So yeah, that about 6 thumbs up you got from me me here; you did well! 👍
Wow what a lot of work just getting to the board! It's a good thing you have all the test equipment and extra chips on hand! You must do a lot of work on electronics as a hobby or living!
Thanks for the vid your method is very good I am going to attempt a clean of my midi studio desk. It’s filthy and crunchy. I have a professional electronics engineer watching over me when I come to test it out. So I don’t fry myself. Thanks for your smiling face and method may you prosper and have fun.
Great work. I have a Sound craft Spirit 24 with one channel showing output when nothing is inserted and a PFL light regardless of button state. I ended up using the AUX bus instead of master. Your method gives me some ideas for rerechecking. The Ballache of getting into it makes me want to put it in the skip!
Great job Mark. I'm guessing boards this big are vulnerable to flex. I wonder would it of been a good idea to replace the wire jumpers with stranded wire. Might see this one again 🙂
Hello Mark, good job you removed the flux because it can cause transmigration of copper between tracks which results in dendrites and ultimately short circuits forming.
fyi Pfl is prefader listen which means you can hear the audio before the fader (the slide thing) there is also post fader listen too. audio can be routed in these beasts in many ways to sub chans mains and aux outs
When I replaced the MCU in an ECU on a Mercedes coupe I used to have, I used foil tape to protect nearby plastic parts for hot air soldering heat. It worked a treat. I've got the older version of this desk. Seems they've cheapened it out quite a bit 😞

I am a PA sound man FOH / MONITOR over 40 years, AND have "The ear's" so to speak. Some artist i have done more then years of touring. I notes that at 3:28 The AFL/PFL is active, the meter then off for left and right. John - SOUNDFILL ® I use Martin Audio - Crest Audio amp's Allen Heath and the Lexicon is A-Brand. In the past have 2 MPX- 1 in my FX Rack's.
I really appreciate the camerawork and editing in these vids.
And just the general problem solving is top-notch.
I watched the vid on the linear turntable earlier.
I don't want to spoil it, but you went above-and-beyond on that one. I would have given up far more easily. lol
As soon as you mentioned opamps in this mixing desk, I KNEW they would all be NJM5532.
It's like the go-to opamp when they don't want to spend too much money. lol
To be fair, that opamp sounds OK. It's quite a good bang-per-buck, excuse the pun.
I'm only half-way through this vid atm. I'm a bit worried that the voltage rails weren't checked before replacing all the opamps.
My guess is that somebody plugged in a cable with 48V Phantom Power (from say one of the XLRs) into those channels, which popped the opamps. Or something a bit more scary, involving mains voltages. lol
Currently working on a behringer xenyx x1204usb Mixer that I bought really cheap with issues on a couple of channels. Hopefully I will be able to fix it soon. Love the editing, camera angles and the sense of humor. Your channel needs more subs.
Loved your positive attitude and also great soldering skills! Subscribed
Fantastic video Mark and a really great repair job - you certainly know your stuff, love watching this.
That was amazing! I NEVER watch stuff with attention, but I watched this!
Nice video, thanks. the symmetrical mix outpit is once again the economy version. Soundcraft loves it. That's not nice. The many buttons and screws are amazing. I once pimped a 24 channel mixer. That was even worse. The potentiometers were still screwed there.
Great repair with a lot of patience and calm. I enjoy watching your videos.
Hi Mark, I have 2 Soundcraft EPM mixers, one a 8 channel and the other a 12 channel. They are very similar except without the FX bit. Both, since 2012, have been reliable so far (that’s me tempting fate). The outputs are “electronically balanced” using the resistors to give the same impedance on each of the balanced connections.
I used a similar arrangement for balanced inputs on the interconnecting leads to enable the unbalanced insert points of the mixer to connect to a 24 track digital recorder (I’m only used 8 channels/tracks at the time). There are separate record (input) and playback (output) leads so the insert points can be used as both input to record and output to mix down via the mixer (in analogue) or using digital for computer mixing etc. My mixers are used to record everything from soloists, choirs to an orchestra for live broadcast hospital radio programmes. The only problem is that the phantom power is ALL channels or none, therefore two mixers. I now have phantom blockers and transformer isolated splitters too.
Looks like it Takes longer to open it and reassemble it than fix it.
I know what to expect now. Thanks Mark.
Enjoyed the post, Analog rules!!!! George from Indiana. USA
a great video, once more Mark! Watching you going around the PCB fixing and mending things, soldering iron on th eone hand and scope probe on the other has really a suspense movie quality to it!! Keep up!!👍👍👍
Lovely Tek scope right there. They will never get old.
I'm just learning to a degree, but I have to say, you're fun to watch, and obviously you know what you are doing!!
Great repair. Love your channel.👍
wow..you are a genius with electronics !
Nice video, thanks for sharing. Greets from Netherlands
Just discovered your channel and I’m glad I did.Mend it Mark !
One of the best channels of its kind...congratulations
WOW, That’s a lot of Screws & Knobs, I found one of those in a Skip while working around the UK a few years back and it worked fine, It was just missing a couple of the Slider Knobs but managed to Sell it on eBay for a tidy sum! 🙂
Good and interesting videos of the equipment and repairs, thanks! I never see anyone ever using that copper de-soldering braid anymore these days. I was surprised to see that people still use those terrible glass fibre pens to clean PCB's - those things were hell on earth, we stopped using them in our factory almost 30 years ago due to the problems the operators got due to the tiny needle like fibres that went into you skin on your hands. God knows what they did to people lungs, a row of 20 ops all using these pens and each bench fitted with a fan to blow the dust from one bench to the next person in front. Then throw in an ultrasonic bath that was using Arklone K, and each op. with a 300ml can of Trich. what a wonderful workplace - No fume extraction, tin lead 60/40 solder, it is a wonder our kids had hands and feet!
Outstanding electronic work, and your cheerful attitude is very refreshing. Cheers
Gotta get me an infrared camera. Great video as usual. I've used an 8 channel version of that desk before. Fortunately never had to repair one. What a pig of a thing to pull apart!
I miss the days when you could unplug the module. It was so much easier and quicker to repair. I recently worked on a Peavey 24 Ch. console and it took me quite some time to disassemble it just to replace one Op amp. At least I had access to all of the controls so I could clean them.
Outstanding work, Mark. I learnt a lot as usual.
REALLY ENJOY THIS VIDEO. AM NOT EVEN GOING TO ASK HOW MUCH MONEY YOU HAVE INVESTED ON THOSE TOOLS....
This one was a fun, action-packed edition mate! Knobs, nuts, chips n crows flyin round left right & centre! And you discover someone else has been messing with it! Grrr! 🤬! Nevertheless you triumphed in the end. 👍💪💥💯👏
Hey I gotta say mate, your soldering methods are as good as mine, & you're the second person ever to get that recognition!👍 Your photography is such that I see how you leave the soldering iron tip in the solder joint for juuust 1 second after you remove the applied solder from the joint. This gives the flux that short extra second to fully activate & do its job before the heat is removed. I see you doing that Mark. 👍 That's nasa standard mate.
I was trying to think of what "naughty" thing someone had done to damage the mixer so extensively, & how power must have be applied to it somehow where it shouldn't have been? Then you mentioned phantom power. D'oh! Of course! That's 48 volts DC, that's supposed to be supplied to the mike via 750 ohm resistors & isolated from the mixer inputs via 47uF capacitors, with 1meg resistors on each of the balanced mike outputs to discharge the capacitors.
So yeah, absolutely, a mixup in the wiring to a phantom power mike is exactly the kinda way to get DC power into a mixer where it shouldn't go!
So yeah, that about 6 thumbs up you got from me me here; you did well! 👍
Nice one Mark, the highlight of my week when you upload another repair video.
It's really fascinating to watch genius people at work :)
Thanks for sharing sire.
Wow what a lot of work just getting to the board! It's a good thing you have all the test equipment and extra chips on hand! You must do a lot of work on electronics as a hobby or living!
without a single clue.., But I'm fascinated and like your man :)
Highly skilled and well trained guy....
Brilliant Electronic Technician !
Brilliant video mate, you really know your stuff
Thanks for the vid your method is very good I am going to attempt a clean of my midi studio desk. It’s filthy and crunchy. I have a professional electronics engineer watching over me when I come to test it out. So I don’t fry myself. Thanks for your smiling face and method may you prosper and have fun.
Hmmm... a bit more complicated than my ancient Series 1 that went to Rock Heaven many years ago! Great video, thanks.
Hey Mark, you have the patience of a saint! Good job mate!
I love soundcraft gear. I used to work on a soundcraft spirit live. I miss it.
Great Job ! Congratulations.
This channel is awesome. My new favourite.
Getting inside is like breaking into a vault. A booby trapped one :)
That was an amazing journey, Mark
Applauding your terrific Skills..!! But wouldn't it be cheaper to chuck it away and buy a new one?
Thanks. As usual, excellent video.
Great work. I have a Sound craft Spirit 24 with one channel showing output when nothing is inserted and a PFL light regardless of button state. I ended up using the AUX bus instead of master.
Your method gives me some ideas for rerechecking.
The Ballache of getting into it makes me want to put it in the skip!
Brave man our Young Mark! Great work!
Nice fix mark well done thanks
Great Job Mark. Well done. Cheers.
How on earth did you work that out? Well done. A fantastic job, well done. I enjoyed this vid. Thank you.
Brilliant repair-man.
Yep. Keep clicking likes - deserves more subscribers
Great job Mark. I'm guessing boards this big are vulnerable to flex. I wonder would it of been a good idea to replace the wire jumpers with stranded wire. Might see this one again 🙂
I love your videos. Nice job
Great job! I swear i heard the six millions dollar man sound effect a couple of time… 😂
Hello Mark, good job you removed the flux because it can cause transmigration of copper between tracks which results in dendrites and ultimately short circuits forming.
You are my new favourite channel.
I use that mixer for about 5 years
And still in good condition
fyi Pfl is prefader listen which means you can hear the audio before the fader (the slide thing) there is also post fader listen too. audio can be routed in these beasts in many ways to sub chans mains and aux outs
HI Mark, love watching your work! Can i ask what's your favourite choice of solder for SMD repairs like this?
That was really satisfying to watch.
When I replaced the MCU in an ECU on a Mercedes coupe I used to have, I used foil tape to protect nearby plastic parts for hot air soldering heat. It worked a treat. I've got the older version of this desk. Seems they've cheapened it out quite a bit 😞
anda begitu hebat, andai saja saya bisa berguru dengan anda pak ☺
