Digidesign Control 24 Mods

[Jkidazz]

Hi

I got a Control 24. It is glitching and faders have a life on their own at times.

A friend modded his with resistors on the PCB for the faders and changed stuff in the PSU. His was working great. Unfortunately he sold it and can't remember what he did.

So, anyone in the know?? 

Thanks!

I would start with PSU filtering, maybe a choke and a couple of caps may help, if you have sparks on your PS rails may be taken as fake 'bits' by your digital stuff. Is not sooo common but if the PS is not so good may be something. Also decoupling noises at your faders may help, small R big C at PS for each, or other critical noise points treatment, if your friend added some resistors on the faders may be to slow down the response in order to get better stability, that would be somewhere in the feedback loop from the position detector to the motor controller.

A friend bought a Control24 with quite the same problems.
Cold solder joints on the powersupply PCB were the problem.

Check solder joints on your powersupply PCB.

I tried to talk someone at Black Lion audio into making an 8-channel preamp card for the Digi Control 24, pres that actually don't suck. And now, several of the main 220uF filter caps have failed and run super hot on my pre cards. I think there is enough room in there to put SSL type pres.  Anyone in here ever messed with those cards are made new ones?

What Control 24 are you referring to? I think there were 2 different C24 models over the years, I don't know if they have a different designation or not

Question: Did you service the faders ? At one of the places I do contracts we found the faders on the Neve DFC did need to be serviced every so often.

During the 2000's into the 2010's I had 2 Control-24's in my studios. They needed a lot of constant service to keep running. The first thing I did was to replace the standard Molex crimp terminals with the upgraded Molex crimp terminals that contact on 3 sides, I believe they were called "Molex D-Flex" or something. I may still have some in the bin if anyone needs me to look up the exact name. This was on all of the power and ground distribution harnesses. This alone fixed the "faders stuck on +6dB" and "flashing LEDs" scenarios most of the time. Then there was a capacitor in the PSU that was too close to a heat sink, and it would dry out every 3 years. I believe it was C11. The solution was to mount that capacitor on the bottom of the board, away from the heat sink. At the time I had detailed notes about all the different procedures to keep these boards running, but I trashed them when I sold the last console. Clients would regularly spill coffee and soda in the faders, luckily the faders were easy to take apart and clean. Usually I could restore the faders 100%, but sometimes I had to replace them with new faders, which were readily available for about $30 apiece. I'm really glad those consoles are out of my life!
