Well after 2 years in storage I finally got to put my 4000e/g on its legs. I bought it 2 years ago driving 24 hours with my wife to purchase. And yesterday it was both of us putting it upright. In these last 2 years I have posted many times and I would like to thank everyone that responded to my posts. I had many questions over the years. I’ve cleaned every channel and redid every fader. They were really bad and now feel like new. Got a Mpower and one computer running so I’ll be booting it up hopefully this week. 👍. I’ll post some pics soon …..
-
Pics soon. Turned console on and as expected issues. I’ve changed a few bus switch’s on test jig for a few channels prior but now with all channels in I have about 30 to swap out. I might have just about that many spare 👍. The main issue are there are a few channels where the cut is constantly on and also I’m unable to cut the rest of the channels. I don’t think they can all be bulbs. Any ideas? I also have to set up the program disc to suit my board. I took pics of my 8” floppy settings so I’ll do that next. Also waiting for wd40 to work on of course one screw on the center section to unscrew. lol
-
I suggest installing the computer bypass connectors. That way you can troubleshoot the cut issues independent of the computer.
If you still have issues, you know those issues are within the console itself.
-
Will do. Thanks
-
k pics. where theres a will theres a way lol !! also pix of it turned on. kinda rushed it but tonight i might bypass computer and work one or two buckets at a time. i bought it as a 32 ch with a spare bucket so im short one bypass plug. ive since purchased 8 channels to fill it up k
-
so today i bypassed computer and only switched on 24 channels. issue continued so i picked 8 channels that seemed to be responding ok. i then transferred those to 1 - 8. i kept console to just first bucket then ;
ch 1 - 8 were put on vca 1
vca 1 - 8 were put on zero
pressing solo on ch 1 - 8 does nothing for either bucket
pressing solo on vca 1 cuts all other vca but not ch 1 - 8
pressing solo on vca 2 - 8 cuts all other channels on both buckets
also when pressing vca to meters vu switch but faders do nothing. i finally got last screw out of of center section but now the channel pull tool seems to not catch that good. might have to redo threads or make new tools. k thanks for any suggestions
-
I was wondering how just you and your wife flipped the console onto its legs. With a little help I see.
Check the ribbon cables that go from the fader board to the lower buss card. Maybe ones not tight.
While you're at it you might want to check the little ribbon jumpers that go between the first and second buckets.
Having someone push from the bottom of the 651 (center section) is always a good idea. Once you get it started it's easy
to get your hands under the ends. Beware, the latching slider rails on the 651 like to fail so having a helper handy is important.
Especially if you don't know if the latches will catch on yours. On mine the front rail won't latch so I cut a piece of 3/4" plywood as
wide as the 651 and 8 3/4 " high and I put it between the back of the faders and under the lip of the 651 to hold it up. Maybe rip a piece of 2 x 4 and have it handy.
-
Thanks. Really rushing so maybe I was thinking of taking all channels out and cleaning connectors and reseating ribbons. Also I got center section up with new 5mm screws. Oxy gold good for connectors ?
-
Do you have Solo Isolate switches in the centre section?
Sounds like from what you describe, the solo bus is not functioning.
Within a bucket of 8, it should work regardless of the centre section status.
However, some channels were modified to have individual channel solo isolate, which was a press switch as part of the Group Trim pot.
Anthony.
-
With further testing I see that if I solo a certain vca 1-8 , ch 1-8 will display cuts but when I flip a ch 1-8 to independent or that corresponding vca fader that was soloed, the cut light would go off. I’ve seen a video where u can group channels. I think I might hook up computer again and program new disc with the info from older drive and see how it goes.
-
K reseated and cleaned connectors on first 3 cards in main section. Seems vu to
Meter shows signs but only ch 1-8. Turning on 1-24 seemed to help. Still issue with cuts and solo. I have all vca to zero. Gonna stop for now and go thru and clean and reseat connections and hopefully it helps a bit. K thanks
-
Okay. I didn’t clean or reseat anything yet but have all buckets on. Here’s the solo/cut situation. Seems like they are almost working. Only thing is some channels input/mic shut off when other solo buttons. Switched on. Seems ch 25-40 and only ch 6 on left side of center section. Maybe board is coming back to life gradually. lol. Priobabaly been dormant for at least 3-4 years. K. 👍👍👍
-
K thanks to all. Gonna work on switch’s and som buttons that have broken off. The solo/cut issue might have been resolved. Not having all bulbs working makes it a bit more difficult to troubleshoot. Will post back after fixing channels and reseating everything. Seems that resolved most things. Also a bit of confusion on how center vca affect solo/cuts. Excitement and rushing things kinda my main flaw lol 👍👍
-
Well after swapping channels around and repairing some switch’s the board seems be coming alive !! One issue is if I solo any ch from 25-40 it cuts the input/mic for other ch from 25-40. Just right side of board which are 6 brown e 2 stereo and 8 black e channels. Could be from multiple startups but i will let board sit til tomorrow and see what happens. More optimistic about things and seems like a great start …..
-
Newbie question. Board is running pretty good so far. Passed audio thru ch 1-2 to test. Monitor alittle noisy but still haven’t cleaned cards and connections yet. But in regards to solo/cut issue on the “e” channels. Is that the way they are suppose to react when a ch is soloed ? I have about 10 manuals and might have to start throughly reading thru them lol. K thanks
-
Yep that's the way E channels behave.
They have different design logic cards
I never noticed until now.
My current console is a split 8000 G with 8x 4000 E channels

-
Been busy troubleshooting and have gotten very far. Board really looks and sounds great. Trying to figure this one out. In mix enabled with computer running only 1-16 and vca 1-8 light up for automation. After a bunch of options I then swapped 17-24 to slot 1-8 and 17-24 lite up on the console. I already swapped out the computer card with another so it’s something other than the lights/switch’s card. Any suggestions. Thanks !!
-
Have sent you an email.
-
I’ve been troubleshooting and swapping channels around. Would all the multiplex cards need to be reset with their jumpers. I’m assuming so in order for total recall to work. Would that affect the automaton ??
-
Yes, All the jumpers need to be switched, unless they have already been switched. The dip switches on the multiplex cards on all modules need to be set to different addresses. The address chart is in the manual.
-
Thanks. I’ve been swapping channels around to test and get things to work. So I’m sure I gotta read the manuals at some point lol. Thanks again !
-
i found multiplex settings in manual and set them up accordingly. i also ran the analogue in test for faders and only 1-16 and vca appeared. 1-16 were frozen open but vca 1-8 tested perfect. gonna swap analogue card and also make some spare 50 pin cables to test
-
K. Some progress. I booted up from my original 8” floppy drive that I repaired and I got all channels to light up in beginning of mix. I don’t have a tape machine or pro tools running yet. Pressing execute brings me to the mix running screen but ofc no sympte running. The vca1-8 faders respond but all the channels are unresponsive. When I perform !tes for faders now
I see rows for 48 channels and still only vca 1-8 respond. All others pretty much wide open close to zero.
-
I looked at manual and found jumper setting for multiplex cards but are there any for the logic cards ? Are they used for working with computer or not. Or are they also used to determine channel location/number ?
-
The Logic Card doesn't have jumpers. It has dip switches, which are also in the manual.
-
Thanks. I looked and couldn’t really see. I’ll take another look Are they on same pages as the multiplex cards. Thanks
-
Ok. Found page for the e293 logic card. Those are with my first 24 channels which are g channels
Before I was working on a e channel with 242 cards. Logic card was a totally different number. I also have 6 e channels with brown eq. All the e channels are in the right side of console. Think I’m gonna start going thru the 24 g channels and get them to work with computer.
-
the dip switchs seem correct corresponding to manual. here is a pic of the link [lk] wiring. is this correct or did prior owner have it modded to not work with computer.
-
Wrong Links. The licks you need to check, are under the VCA (13) card. U have to remove the card on each channel to see.
-
Thanks Dave. I did install some multiplex cards and moved the pin to correct link but now I don’t remember about doing all the channels. I will check them all later today. The board was in storage and channels were too.
-
so now i'm thinking i only moved pins for the new 8 "e" 242 channels i bought after the console. i installed the multiplex cards and transferred the pins but thought i did the original 32 channels. been a crazy 6 months planning the move and i must have forgot about doing the rest here are 2 pics and im assuming the one going to bypass is the incorrect one. Thanks Dave ! I'm hoping this is the solution once i'm done There’s also the vca trim that has no jumper.
-
Set all jumpers and resolded pins. A few channels are pulled out. So a total of 32 installed for now. Still no movement on bar graphs during test. I tried using original disc programmed for 32 ch and turning off last bucket. Still no movement. Maybe I’m rushing things or missing something. Vca and master still show movement. How can I make a 40 channel program disc setup for this console. Commands online do not work. Sorry about being all over the place. Just wanna set this console up and start making music. Vca to meter does show movement on meters so I’m thinking it’s problem with computer. If master Vca card was problem Vca to meter wouldn’t be working ??
-
You need to post some photos of the console and computer, as it is very difficult to interpret a description of the issues.
In particular :-
50 ribbons connections at console, computer, and within the computer.
Within the console frame, under the faders (fader bus card).
Under the console - with interest in the 20 way S16E cable.
Are you using a computer bypass unit (1RU, located in computer rack).
I suspect something is not plugged in correctly.
Anthony.
-
i guess i can say technician error on this one. i never connected the total recall cable inside computer figuring it wasnt needed yet as soon as i connected and ran test faders responded !! thanks again Anthony and the rest. 3 faders still havent responded but i can get to those soon. i still need to connect the heavy ground cable between board and computer so im assuming thats a must also. waiting 2 years has really motivated me and i might be just getting ahead of things but im really learning things as i go which is great for the future. k
-
More tech errors Not so funny. I was fixing channels and some were fader issues. Swapping out things I have most of the channels functioning but then I heard a slight distortion out of the right side speaker. I always notice it was lower output but I then investigated with the power on. I blew the 18 rail trace on main center section. I’ve soldered on a jumper and all is good but now no monitoring. The RF comp card is giving a short to the meter bit taking it out still brings no output. I guess something was going slowly after I’ve turned on console after all these years. I should recap the whole center section. But it’s a learning lesson for the future.
-
Repaired a few more traces on main board. Man I was so close. Maybe from sitting that long things were bound to go but I should have never taken out and tried to reseat the cards with power on 🤯🤯 it just seems the monitoring is affected. One 26card shorts out the bus comp meter and taking it out just resets it to zero. With just left side in still no signal. Maybe a hint of master all the way up with channel input also. Ok. Amy suggestion appreciated. Going thru manual and testing main board voltages
-
Wow. After trying and measuring all day. And soldering a few traces on main board. I remember I bought some spare cards awhile ago when available. I was chasing missing +15v on cards 26 to 27 and sure enough the only spare I have is 27. Which when swapped brought 15v back. While troubleshooting this has brought me more knowledge I’m starting to believe in a higher power. lol. During the move I dropped a Sony dmx r100 mixer I will be using for demos and multing keyboard and broke the front panel and on my last day in NY I went to pick up a eBay item and the kindest man in the world had 2 of the Sonys for sale. He basically gave them to me for free. I seriously hope the road forward with this beauty doesn’t bring me that much of a scare. But I definitely need to find out what’s going on with the rf card. Maybe some new chips and re cap asap
-
Make sure you have the jumper plug in, under the patchbay for the master section, like all the channel buckets.
-
I’ll try and post pic of under patchbay. By jumper fo u mean cabling from computer ? I have the 5 channel buckets and a vca 1-8 if that’s what your referencing. I’ve just started to make dl cabling for my 2” machine. For audio just plugging into patchbay now from laptop.
-
Ok. Play time over now. Waiting all these years has me rushing things. Finally taking it apart and cleaning and testing all ribbon cables and connectors. Also probably gonna start recapping some of the center section cards. I’ll post some pics but since this will be my board til ever I might as well get it right from the start 👍
-
here are some pics. the fader bus cards have a solid pc they are screwed into. the channels bus cards are a bit trickier maybe. thinking of leaving them in and clean them. i see though if i start in each bucket on the right placing cards back in it might be easy to line both cards up.
-
Update. Totally took apart console and Deoxit and 99% all boards and connections. Pretty much looking brand new inside. Beforehand I was chasing a issue with meters pegging with vca to meters engaged. Putting everything back together I still had issue. Turns out I started to inspect computer and found one pin on the analog output card indented. Also a loose pc of solder that was shorting 2 pins. I don’t know which of these 2 cleared the issue but it did. 👍👍
-
Still learning lol. Working on faders and at unity some read perfect and some read low. Researching how to test with multimeter I notice some are 2.7 and others higher value. I guess mismatch of faders need to be brought into account. Gonna try and keep separate buckets will each value
