Power connections

Hi Hivemind! I’m building a new rig and need a way to get barrel connections through the side of the case. Iremember a conversation about 2.1 mm barrel connections where Lars mentioned a mountable coupling that would be purrfect… Anyone know where to find it? Or at least find that conversation?

You could use (or make something like) this: Round Panel Mount 5.5mm/2.1mm DC Barrel Jack Extension Cable [30cm long] : ID 5607 : $4.95 : Adafruit Industries, Unique & fun DIY electronics and kits
There are a lot of different panel mount 2.1mm jacks available.
How are you planning to distribute the voltage once it goes through the side of the case?

Yea the Idea of a single 12v line into the case is nice but you then need to distribute all the lines to each module. A “inside the case” distro board could be an interesting thing. Long enough to use shorty cables, staggered jacks horizontal so you could place it between two rows. I recently picked up the DC Distro and it totally cleaned up my issues with powerup. I am currently 6u x 90 wide and about 2/3 full. I also just kept the euro power in place for audio 3u modules and Sensory Translator. The inside of the case looks like a scene from Brazil! I think my plan when more modules are released is to figure out how to do something along those lines. If not I will end up with a 2nd DC Distro and also minimal Eurorack power. Not the end of the world but It would be nice to cut back on exterior cables and switches.

For a passive DC barrel busboard you could easily mount inside of a case, message @KludgeDredd.


Thanks for the referral!

If anyone’s interested, got a few more available. $30ea + shipping from Texas.

i am using these items for in the case distro:

bus bar - screwed into case (its wood, used screws included)

pre made tails- (could make your own, see last link)

im sure there are better 12v 2.1 hoodas but i felt these were decent copper quality (?)

JACK-- not the cheapest but it mates with a locking plug.


the bushing on this one is a little short IMHO so i use this NL d-series panel, with the RCA removed. - (loosen nut on rear to remove)
Neutrik NF2D-B-2 RCA Jack D-Series Red/Black.
You could use any d-sub rca or bnc size and be fine i think.

using the d-series is also nice because the connector then sits flush(ish) with the side of case and less chance of getting whacked off whilst being in your trunk or truck.

is supposedly a longer bushing but the specs place it same as the AS.

both take a dust cover :slight_smile:


-this connects with, if you want locking-
https://www.mouser.com/ProductDetail/502-767KS17 (lg diameter cable)
https://www.mouser.com/ProductDetail/502-767KS15 (med diameter cable)
https://www.mouser.com/ProductDetail/502-767KS12 (small diam cable)

–cheaper ($2.00) not locking plug but still not the cheapest ( i have a few and cross threaded less than the CUI part on mouser for approx 1.30 or so.)
