For those who wondered what this beast cost back in the days. The MSRP for the M3000A reached from $11k to $17k, for 24-56 channels with VCAs.
That is a decent price for such a mixer. Expected it to cost more
Mag shielding on relays probably to avoid magnetically coupling clicks into nearby low-level audio signals rather than adjacent relays.
Haha 7 years later and 69 likes. Niiiice
Insert is to allow effects to be placed in-line with individual inputs - things like compressors/limiters, reverb etc.
+mikeselectricstuff
I believe it is classed as a channel insert that allows you to pass the signal path to an external device and then back before the signal is passed onto the rest of the channel.
+mikeselectricstuff Yeah, although reverbs and delays are usually put on an effect bus (the middle 'matrix' part of the channel section).
+mikeselectricstuff You mean all those except the reverb, hah!
+Marc Jacobi Nah just give the whole effect its own return channel! Look at all those suckers on the far right. More mixing more better.
+Marc Jacobi It depends on whether you want to use an effect on just one channel or on a subgroup or on several channels across subgroups. It's not that uncommon to have something like reverb as an insert.
your cordless screwdriver makes really weird whistling noises
;) :D
That's because Dave is a Time Lord ;-)
With all pots, filters, VCA:s and opamps, wire looms it migh contain a nice set of parts for making an analog synth.
Or the worlds most complex fuzz pedal ever created.
KNOBS! KNOOOOOOOOOOOOOOOOBS!
Cracked me up. :)
+The Signal Path Blog Knobs are exciting!
+The Signal Path Blog He layed down on a bed of knobs and none poked him hard enough to break. ^_^
+The Signal Path Blog Me, as well! Pretty much my internal moaning when I'm around big switch panels. Dave's a very funny fellow-- in a serious way!
+EEVblog Don't you DARE let your wife see this! She may start questioning your sanity, or worse! XDD
+Sean Buckwell I was going to say, no wonder he's tearing it down, there's a strange noise coming from that one master knob. wah wah wahhhhh..
I'd love to see/hear you tear down/analyze a studio quality ultra discreet recording console. Something like API/NEVE/ SSL. The electronic engineering that goes into making them extremely efficient and quiet audio path's would be such a cool concept to see you explain. I am an audio engineer and merely a hobbyist at electronics. Love your vids. Thanks! -Jordan
Having been the technical friend of a number of musicians years ago I can say they aren't very complex to use. It's intimidating, but it's just a lot of repetition. The real challenge is having an ear for what you are doing.
There are plenty of people that will say they want to help be a roady so they can meet the band, hang out, have fun, learn how to use the equipment... After running a couple dozen cables they tend to suddenly disappear. Those that do stick around to help set everything up are not there when it's time to take it all down.
Another fun thing about doing live audio at a concert is that when everything runs well the tech gets no attention. If a guitarist is standing to close to his amp and it feedbacks (not something the board operator can control), the audience turns and give the tech The Eye.
So true.....
The only way you know you are doing a good job is if nobody notices XD And i dont get the pikers, there is no feeling like seeing a gig through from plan to bumpout, the feeling when you get off and chill is incomparable
Absolutely agree!
I spent my best years working at a radio station and doing live sound on this puppy's younger cousin. As soon as I saw the thumbnail my hands were shaking. This video was a treat. Brought back memories of diagnosing in the field and bodging on-the-spot repairs. Beautiful old school engineering. These devices really have a soul. Just superb.
Thanks a bunch, Dave!
Hi Dave! It seems you can read in my mind! Im sound engineer on live events and about 4 days ago i was looking on your channel for "mixing console teardown" -presumably Tuesday :P. And now you're publishing exactly what i was trying to find. Thanks for your videos i've learned tons of knolwedge. Thank you again!
Awesome video Dave, your efforts are appreciated! :)
Worked on pro audio/video in a previous life. These units were well built and a joy to work on. Great vid as always.
I never get tired of watching you tear things apart explaining how it works.
What a great thing for a teardown.....Thanx Dave!!!
I used to work with a little brother with 32ch into 16ch sub into 2ch main out with lots of subOutd for stage monitoring and effects...
YM-consoles always done a good job, when I worked on and with them, especially in live situations where a clear routing is essential..
What a nice thing to see one if them here! :)
I feel special because i know what everything does xD
+Geoxor Well, once you know how to use everything on channel 1, you basically know how 90% of it works.
+Geoxor me to mate
lolz larkin yup :P
i know how they work cus i produce music and the terms that the mixer has writen on it is oftenly used in DAWs (Digital audio workspace) (aka music making program :P)
+Geoxor Good boy. I was trained to use recording studios and couldn't find a job so I got an electrical engineering degree instead.
+Geoxor Yea :P Finally not everything on Dave's channel goes over my head XD
Great teardown, moooore.
Who needs TV, when we have Dave and Dave? :)
I'm a live sound audio engineer. This was better than porn to me!!! :)
+erikdravn me too in the past, reminds me of the days where i used to do FOH....I used these consoles...:)
12 hours + per week combined at my church for
The past 4 or 5 years. It's a thankless job isn't it? Good to see another member of the “club”
Loved this also, takes me back, I gave up FOH mixing 5 or 6 years ago (Nexo, Crown, Allen & Heath).
+UNENSLAVER haha, same here. nice to hear Dave figure out my domain
+erikdravn I thought I was watching snuff porn though. He said they put it back together when they were done so it's cool.
Interesting video, very nicely built device. Thanks for showing.
I have the baby brother to this console (mc2403) and was incredibly interested in this video. It is so neat to have someone who really understands electronics dissecting the various functions even when he has no clue how to use, or even the purpose of some of the parts. Amazing, now I want to experiment with my own board more.
These consoles though they look quite impressive were built as a low cost alternative to there PM series (PM4000) which were one of the industry standard touring desks.
Such a gorgeous piece of tech, if bloody massive
I'd thin that big-ass ground strapping is more about signal integrity than current
+mikeselectricstuff Well, yes, not actual current handling ability, as we are only talking a few amps which a connector pin or two could handle. But getting extremely low drop over big distances at those currents requires those big strappings for low impedance.
+EEVblog They are indeed there for signal integrity. My Allen&Heath mixer has one big strip going along the whole board (only 24 channels).
+mikeselectricstuff You are alright Mike, and to avoid ground loops too.
+Wouter Weggelaar And I'd much rather have the Allen & Heath too. Much better sounding and better built desks than Yamaha. At this level the boards should all be fibreglass and all sliders and pots should me mounted on discreet channel strips for serviceability.
+mikeselectricstuff If you look into the service manual the big copper strapping is labeled "SUM-GND". It's not only the power-return but also the reference voltage for the busses (the summing junction).
Some boards do the sensible thing and have separate ground-reference pins on their bus connectors, thereby decoupling power distribution from the signal-reference. But probably copper was much cheaper when this board was built ;-).
ST = Stereo
Insert = Place an external bit of equipment in line with whats in already.
Dave if you've got any questions just ask, my job is to operate them.
+Cameron Marks I have a suspicion that you're not the only sound engineer in this crowd ;)
+hingeslevers Oh, he's not, I am as well.
+hingeslevers
Well, I'm a former, but yeah, definitely not.
+hingeslevers
I played with Winamp equalizer plugin in the 90s, does that count ?!
+Ge Trolli sure
Always wanted to take one of those apart and see how it worked :) Cheers mate for the video!!! I could build so much stuff with that thing.
this is right up my ally, thanks for sharing man.
Thanks, I've picked one up and doing some service work on it now.
Hi Dave, the SSM2018 is made by Analog Devices and is a Trimless Voltage Controlled Amplifier. I had a friend that was into designing custom audio equipment so I recognized the part number.
Really enjoyed the teardown, don't often get to see gear bigger than yourself!
That is one sexy mixing console, gotta love Yamaha mixers!
Excellent. Thanks Dave.
I love how for the first time, I know more about a product on the EEV-Blog than Dave. At least about how you use it ;)
That's what I needed:
Top tier teardown.
Having worked a PM1000 16x4 I can attest these are sweet machines in every possible way. Smooth sliders with rubber rollers on the back, contoured knobs you can tweak in the dark with full confidence, not many machines out there you can operate completely by touch like these.
VCA = Voltage Controlled Amplifier. In this mixer, this facilitates mixing multiple channels using a single fader. Helpful for grouping drums, etc.
I love these big teardowns
when the video first started, I thought, that's small then Dave pops up then mind blown, that's huge!
thanks dave - killer content once again. got a lot out of this video.
The arrays above the channel gain sliders are for individual monitor levels. The talk-back is so the board operator can talk through the PA system to the crew or to the performers during rehearsals . Talk-back is not widely used anymore except in garage / bar bands where the musicians are all sound engineers lol, and has been replaces by portable two-way radios. Performers no longer call the shots on how a system is mixed and EQ'ed either like they use to, it is all on the ears of the tech, like it should be..
That sports venue got the hard metal shaft from the sound company who sold them that thing, EPIC OVERKILL
I've been waiting for you to dissect some audio gear!
another reason to shield those relays is to not cause noise inducting into the audio channels. clicks, pops, and interruptions.
Dissection of the Mixing console of my dreams..
Yep The knobs are hypnotizing.
I had a 48 channel analog mixing console once. I used it for Skype. :/
Clicked the like button within 8 seconds from video start because of nice introduction :)
love this one.. please do some more on musical equipment.
I know that desk very well.. I trained on a PM3000 back in the 90's and used the M3000 often enough over the years ... seeing this makes me feel kind of old lol
The insert jack on each channel is a TRS (tip, ring, sleeve) connection that allows a single cable to be both input and output. You use them to send a channel to an effects chain and then loop it back into the mixer. It's like a stereo headphone connector with one channel being an output, and one being an input.
You can't imagine, how excited I am to watch this video! I'm sort of a selfmade Audio Engineer, and love to tear down my equipment, repair it or develop my own stuff. This is so inspiring!
My Yamaha 01V Digital Mixer was really nice to tear down, Yamaha clearly knows how to make their stuff servicable. really nice system engineering! This bad boy on the other hand looks a lot more challenging :D At that size it's really hard to make it servicable.
The phantom power caps where the only part that died so far in my 01V, they were only rated for about 50V, sadly that seems to be "okay" to save cost.
The SILs from JRC are often used in Yamaha mixers I saw so far, they seem to prever SIL-packages, e.g. for their DM2000 digital console. 5532 are not that often used there, I guess, maybe for saving space.
For me personally, this was one of your most interesting videos, even without you knowing everything about it while filming. Thank you, I really liked it!
What a nice console! I've been working doing monitors on an Crest HP-EIGHT 32, but moving up to something like this would be fantastic. Except lugging it around of course!
I just picked up a 16 channel Tascam recording board today for some small home recording projects. The guy I bought it from purchased it brand new in 2011, opened the box to make sure that everything was there and then never got around to using it. When I say this thing is in brand new condition, I'm not kidding. The plastic bag covering it was still taped closed and the power supply cables still had those twisty things on them to keep them bundled. The best part..... I got it for $65 US. (Deal of the century!) I was feeling pretty good about my new board until I clicked on this video. Now I want to go kick it. LOL I'll just go play with some faders on my 32 chan live board to make myself feel better. :-)
That's an entry level, very entry level, touring desk. The upper end consoles have individual modules that you can remove on a singular basis for repair, replacement, or even reconfiguration.
I learned live mixing on this thing's big brother, the PM3000 (and later, the next generation PM4000). The PM's are even more modular, in that each individual channel can come out and be replaced on it's own, and you can get mono or stereo modules.
The Matrix sends are used for a lot of things; sends to time based effects (reverb, delay, etc.), monitor mixers so the players on stage can hear each other, delay clusters (speaker clusters placed further back in the room, and delayed to match the mains - this is to fill dead spots in the room, and is pretty uncommon these days, as everyone else seems to love line arrays), and sub-mixing things like drum sets (though on a console like this, you are more likely to use the VCA's).
VCA's are control groups. You assign the individual channels to the central VCA faders, and you can control the channels in groups. They have VCA group mutes as well. On this generation, the scene memories usually just dealt with the VCA groups. So, you mix the drums, and assign them all to (say) VCA 1, and you can control the overall drum level with one fader. You can also use one of the matrix busses for this, but the extra summing will usually add more noise than you really want.
The stereo channels are mostly used for effects returns.
Inserts are for amplitude effects (compression, mostly, and noise gates).
The mic input in the mains section (the center section) is for a talk back mic, so you can communicate with the stage during sound check.
40 channels of noise (and 20 mix busses) adds up quickly - the shielding on the relays is not optional! Keeping the noise floor below 90dB is tough! That's a big part of the external power supply too - internal power supplies just don't work on boards this big!!!
Yamaha boards have a mixed reputation - some people love them, because they are very clean, and basically do exactly what you tell them to, with out coloring the sound. The EQ's are considered by many sound engineers to be rather sterile. I tend to think it is just a matter of preference. I think they sound great for jazz, classical, or corporate talk talk gigs. Not great for rock and roll, though! What they really do, though, is expose the mixer's skill level - you get out what you put in, and if you know what you are doing it will do exactly what you tell it to do. A lot less forgiving than some boards if you aren't so skilled!
It's not a baby, but it is a mid-level professional console, and a 20-30 year old design at that. These days, everything is digital, and EVERY promoter is constantly arguing for smaller and smaller footprints at front of house. Still, back in the day, those boards probably did more events than any of the higher end consoles, and while they are not quite as versatile as a 4k or Midas XL4, it probably cost about a quarter of the cash, and they sound pretty decent.
The good old days with the PM4000 when you had to tear out the channel strips between songs and hose them down with contact cleaner...
Regular scheduled maintenance, my friend, regular scheduled maintenance. We used to clean our patch bays every six months. Sure, it's a pain, but it sure helps avoid problems.
That 7805 5V rail made me smile. Simplicity at it's finest.
But really, I gotta say, this thing has some seriously complex analog mixing circuitry put into it.
Very well engineered. Seems fairly straightforward to service as well.
+1 to Yamaha. Yamaha FTW!
Loved this video. Many of your videos go right over my head, but with this one I found myself yelling at the screen trying to tell you what stuff was and why it was like that.
I do live sound (not to mention lighting, etc), I'd really like to see your reaction to the insides of some other consoles.
There is a BIG reason having things modular is key, if something dies before a show or during a show and you NEED it, it is not unheard of to open up the console and start having at it, swapping parts, making spot repairs at the component level even.
I remember killing a section of a console mid-show (at a music festival) during a small act to repair a section of the console live. Had consoles open mid show far too many times.
+Steven Allen Live on-site repair during a show, awesome!
EEVblog yes indeed. Gotta do our best to make sure the show goes on! Thank god the better consoles are very modular.
A soldering iron inside a console on site is a bit of a nerve racking thing I'd say.
+Steven Allen You should get a fake pair of legs (i.e. jeans bottoms and boots), lift a section and stuff that in. Any one complains just say "The guys in there now working on it!"
+Steven Allen As an Audio Engineer myself, its really interesting to see the internals of a board, although I cringed at the idea of tearing a board apart. Regardless, cool to know the things buried within!
45redrooster
Completely agree... I have an old Soundcraft Spirit Studio that I've had to tear apart to get working fully again. Too bad the thing was way too much of a pain in the butt to transport most of the time for me lol
Three years late here, but...
It was fun to see this blast from the past. In my career I kind of skipped right over the 3000 series and went from the 2K to the 4K and then the 5K. Now, of course, everything is digital and these old workhorses are rarely seen.
Anyhow, it was really fun to read all the comments about what this and that does. We used to take the opener's console into the sub-in's so that we could use the same monitors while keeping the opening band engineers from messing up our mix on the headliners console.
Inserts on the outputs were, 99% of the time, used for EQ's to keep the feedback to a minimum.
As far as inserts on the inputs, I saw a lot of people here that had "absolute" ideas about how dynamics, eq, and effects should be handled. I'm guessing they are pretty linear thinkers. I would suggest that they open their minds to the endless ways of making sound great (again!) Sorry! Couldn't help myself...
I will tell you that I have seen every variation on a theme that you could think of with inserts and how to use them. There is no wrong way to do things if it works for you and your artist. Thanks Dave. Great stuff.
This would be the best answer to "why digital" questions
I agree!
+Abdurrahim Cakar Also analog EQ creates phase shifts between different frequencies leading to quite a bit of distortion if not compensated properly. You don't have that effect in a digital mixer. Width 24 bit resolution and 96 kHz sample rate being standard you don't have any noticeable signal degradation due to the digitization itself.
+Abdurrahim Cakar I'd exchange my laptop for one of these any day :)
why digital ? "every idiot can count to one"!! :DD
+Jan Vomočil
Why Digital ? Because there's no room for noise between 0 and 1 !!
That's huge wow!! I serviced one that I don't recall how many ch it was I think either 28 or 38 it's been a long time ago. It was at a big Baptist church I went picked it up for service. Had broke connections on the sliders where they were putting their weight on the controls hooking stuff up in the back of it Lotta contact cleaner went into that thing.
I find its usually the mute buttons that go first... some guys just hammer down on those and they just die
+Julian Amrine It's usually the pot's that go first on yamaha's they get nice and scratchy, a couple twists and they're usually fine
+Scott Kuker
Not if you keep on top of your scheduled maintenance. The PM3K I learned on was 20 years old, with about 200-250 shows a year, and had most of it's original faders, and none of them were scratchy. The ones which were replaced were because the whole channel had been replaced, usually because of a bad pot or VCA. Clean and lube your faders every year or so!
+Scott Kuker spray deoxit (electrical contact cleaner) into your pots and switches. just dont use on faders, as they are open and attract dust.
Even better, use the liquids CaigLube/DeOxit! F5 and DeOxIt! 100% that comes in the bottle with the brush/needle tip. That way, you're not putting chemical where it's not needed. Less waste = more useful product.
These things are really impressive I've been working with analog audio consoles for most of my life but these things are being phased out for digital consoles which are smaller, can handle more channels and have some really cool features. But analog consoles are still the way to go if you want cheap. Yamaha's flagship digital console the CL5 retails for $26,000 US dollars and its little brother the QL5 retails for $16,000, you can get an analog console for so much cheaper. The other thing to keep in mind here is servicablity, this thing was designed to be serviced by roadies because they don't have time to have a piece of equipment down for weeks due to repair. This way they can quickly replace a module and do regular maintnce in 1 to 2 hours rather than 1 to 2 weeks. The parts are very likey made by JRC since that was Yamaha's go to supplier for things of this era. The CL5 and QL5 take inspiration from this console with the matrix system. Normally analog audio consoles indivual channel knobs go as follows: Gain, AUX send 1-4 and somtimes 5 and 6, High EQ, High Mid EQ, Low Mid EQ, Low EQ, Pan, and then mute, fader and fader send. AUX sends are just a way to send audio to another source becides the main output, and they can be either pre fader or post fader, pre fader meaning that the signal leaves the AUX send before it goes to the fader and post fader meaning it leaves the AUX send after it leaves the fader.
I've worked on a M5000 with the motor driven sliders. BIG board!
Glad to see you used your skin's 'snapshot learn/store' function to capture all the knob and fader settings before you took it apart.
You are a great teacher. Thanks!!!
When I was a senior in high school my buddy asked me to help do the mixing of the school play and I get there that night and none of the other sound guys could make it. I had to learn how to use that machine and mix everyone on stage and the pit band, which is a job meant for 3 people.
That is a thing of beauty
Best. Teardown. Ever! I actually understood most of it for once! :-)
That was fascinating. Just as complex as one might think they are inside.
Good video. A boat load of salvageable parts from that one.
Hey Dave,
Coming from a synth world, that SSM chip is a VCA chip.
SSM made many DIP package solutions to common circuits in music electronics. Most notably, SSM made oscillators and filters that were used in many famous synthesizers such as the Korg Polysix and Sequential Circuits Prophet 5 Rev 2.
Along with SSM, Curtis Electro Music (CEM) also made similar chips that often replaced the SSM chips in later model revisions.
Would be cool to see a synthesizer teardown from you!
Had two 24ch analog board before we went to pro tools and their consoles, the PSU was serious business! Rackmount like you said, a huge monster. A diode kept burning out every now and then and it needed to be repaired. That 40 channel one must be an even bigger monster :O
+Luciano Alberto That Pro Tools S5 Fusion desk doesn't look a whole lot smaller !!
:-)
With the "scene memory" you can program mute scenes, so you recall which channel is muted which unmuted. Same works with mute groups, you can mute/unmute multiply channels using one button
For someone who has no idea how this works going in, you did pretty damn good job of figuring most of it out. Really enjoyed this vid!
+The Bright Pixel Thanks.
I thought that was on your bench until you jumped up behind it. Man that thing's huge.
Dave: in the master section where you mentioned that the board to board interconnects are not continued on the right edge of the board, had you looked up at the master section you would have seen that there is a board which hangs down into that space. and as such it was for clearance. if it was not for clearance I would think the copper bus bar would have been straight across rather than dipped way below the boards.
+David Nelson Ah, ok, of course!
+David Nelson It's also likely that the board was designed for multiple form factors. Mixers tend to be pretty modular in construction, as this video demonstrates really well.
Looks to me like the board that hangs down is the scene logic - potentially the bus board came from an older model without scene control.
I loved the series you did with Doug Ford on mic design. It would be awesome if you could get with someone from the audio world and talk filters, gain structures, etc from an electrical perspective
In 1986 I built the (Jaycar?) 16 channel mixer kit. Boy, was that ever a job of work.
Used with a couple of 300W MOSFET power amp kits also from Jaycar.
Once debugged, it wasn't a bad piece of kit.
The split in the bus board is the traditional right side end to a mixer, so the channels to the right are addons.
You're right about fader maintenance. We had a 64 fader SSL console which needed fader service after ten years. Electrically, they were fine, but they started to stick slightly. Each week, I would remove a few of the Penny & Giles faders, disassemble, clean, lube, reassemble, test and reinstall them. It took about 2 hours for each.
+Chris W Each week?!
I only did a few faders each week. It took many months to complete.
KNOBS!!! As a sound engineer this teardown almost made me cry ;)
Yeah, was also my first thought but when I saw how "crusty" those faders look (pots have probably also had it), this console should have been retired a while ago and wasn't worth it anymore (at least not in that price range)
Never have I seen a man so excited about loads of knobs in front of him.
Hi Dave, Thanks for the awesome videos, Really enjoyed most of them.
Can I make a suggestion / request? When you overlay component specs etc, could you fade them out? It's be great to know if I have to hit pause to finish digesting the info.
Cheers.
Awesome intro!
I’m making my own sound. My own music. My own creativity. Having something like this to use or completely harvest parts from would make my Thinker Tickle.
Neat teardown Dave! Thinking it over, a power supply for it wouldn't be too hard to cludge together. The power requirements aren't ridiculous. Hope it found a good home and not the scrap, as with that many channels, it was mostly still in woking order I'd wager. And only ~15yo. My Yamaha Clavinova is older, and going strong!
The relays are for the "scene" feature. Scene allows you to create, well, scenes with certain channels muted or open. By switching to the next scene, specified channels are muted or unmuted.
It's really interesting to see all this audio-gear! Especially for an upcoming electronics engineer who wants to work in the audio industry ;)
30:25 Well, I have seen one mounted on the writing head as a heatsink in a Sharp VHS once, so I am not surprised by 7805s popping up here and there since a long time...
that little weird stop with the bottom board and the bends in ground strap and wires is only for clearance of the board that you swung up.
That Analog Devices chip ssm2018 will be a balanced to singe-ended converter or vice vera with laser trimmed resistors for optimum common mode rejection / phase balance.
The grounding is the amazing this in kit like this! Keeping every signal route clean with noise -100dB is not trivial even with far simpiler circuits.
I think the relays are shielded to prevent the switching magnetic fields from inducing pulses of current into the signal path of nearby wires.
I would think a small click in a signal being amplified by tens of thousands of watts and pumped through scores of speakers might be a life-changing experience.
dat tripod fail
priceless 😂

That's the core of the joke.
My school upgraded theirs back in the day when I was in year 8, I just took one module as they were all the same. It was from the 1970s and used LED VU meters and Op amps to drive them, I think I still do have some of the boards, but several years ago I desolderered the components on the bulk of them. I was pretty good at shoving busted electronics in my bag, but this was far to big and heavy for mine.
FANTASTIC VID. I really lament the fact that something like CZcams wasn't around when I was doing my electrical, - electrical mind you, - training. Gold plated. What else can I say?
damn bro, mixing consoles is one of my loves..haha didnt know you did teardowns on stuff this size. not exactly a multimeter 😃
The SSM2018 is a VCA (Voltage controlled Amplifier). I work on Analog Synth Keyboards that use other SSM chips
One of the best
Insert I/O = INSERT In & OUT. Use a TRS ---> TS/TS . TRS jack goes into the insert plug at the back of your consol and the 2 TS jacks go into INPUT & OUTPUT of your external device ( Noise gate, compressor, or whatever you want in your channel path)
The huge copper straps and the shields on the relays are for the same reason to be able to meet the noise specifications. (relays pop on release)
Dave is so badass he can knock his camera onto the ground if it gets in his way... It's what he does.
i have no idea what he is on about, but still,.. amazing :).
great video
dave the mix inserts are to "patch in" outboard gear..mainly dynamics processing like compressors, etc
It's funny to see how these big guys have been replaced by things as small as the X32 by Behringer.
But the x32 does loads of good on the ol' back! (Seasonal job is a Live Sound Engineer)
Dave, Many of thease boards are CTO, so there's alot of "Modularity" to them, I've seen that same board witthout the channels to the right of the master section. That yamaha is actually one of the "BMW's of its age" Although very clean sounding board, not very complex in comparison to others in its same vintage. even for a FOH board. There's even Field retrofit kits for some consoles to allow you to move your mains section around in the frame or to add aditional features. Great tear-down tho.... Love to see ya tear its powersupply apart.... those things were EPIC
