Alternatives to DB25 Connectors

Can anyone advise on what alternatives there are for creating multi-pair cables or snakes without using DB25 connectors?

I find that DB25 connectors are fine for very “static” applications, however i've found that situations that involve unplugging and plugging and or set ups where the connector might have the weight of the cable causes connection problems.

So what multi-pin connectors are the most robust and use a different locking mechanism than the screw system of DB25 connectors (which I detest)?

I want to get a some custom multi-pair cables sets made with breakout boxes and want to absolutely avoid DB25 connectors so any recommendations would be super appreciated.

I agree that DSUB connectors are not suitable for portable "snake" type applications.
Mostly because there are no appropriate shell/attachment options available that are rugged enough.
But then DSUB connectors weren't designed for that kind of applications.

Here are a few popular multi-channel connector options.
Of course, there are hundreds of choices from other manufacturers and vendors.

Note that some options require special tools which are quite expensive.
Crimping tools and dies, pin insertion and extration tools which could cost hundreds of $£€
But many (most?) use "solder cups" but can be extraordinarily fiddly to terminate reliably.

All our stage gear has been wired as EDAC/ELCO as have our moveable studios.
Works great but it took weeks to have the wiring done (which I did not do, thankfully.) We hired in professionals for this part of it.
So for convenience (and compatibility with standard equipment), D-subs are still in use within racks (with strain-relief bars, etc) but the racks are tied together via EDAC/ELCO.

Ok thanks for this. I'm trying to understand what are the "standard" connectors in the rigorous touring and live environment.

I'm just trying to find a robust alternative to DB25s so if I need to run a snake with all the synths and drum machines to let's say a rack of pre-amps or comps, the connector can be (for example EDAC/ELCO) which then connects to a breakout box/patchbay.

Have you found that these actually sit more tightly without wiggle compared to DB25s?

Have you ever tried these Amphenol connectors or know anything about them? Are they used in live sound/touring?:

I’m not a live sound/touring guy. The tours I’ve done are of the more recent variety that touch on my field that have recently become popular (what I call “film composer as rock star with Cirque du Soleil mixed in”)

I have used at least a version of the connector you linked. But it was with pre-built equipment (not custom wired).

The ELCO/EDAM connectors are super robust and very well tested (I can’t remember how long they’ve been in use but I feel like they go back to at least the 70s). They are also bulky so not easy to hide.

I rather prefer the circular "military-style" connectors.
I don't like the exposed pins of the EDAC/ELCO style connectors.
They seem much more vulnerable when not connected.
Unless you buy spare mating shells and always use them to protect the pins while moving.

But it depends a lot on your circumstances.
The circular connectors are much more robust for heavy-duty use on the road.
Especially if they are dragged around and man-handled by primate stage-hands, etc.

OTOH, the EDAC/ELCO connectors are more suitable for "fixed" applications like studios, etc.
They are easier to terminate, but lower density. So it also depends on how many channels, etc.

The metal-shell original versions of the circular military connectors are quite expensive.
But there are modern plastic versions which are often seen in multi-channel audio applications.
Especially for quick disconnects in studios where you aren't going out on the road.

Are they more complicated to wire up than DB25s? Where can I find the metal shell originals?

Most have pins closer together than DSUB connectors. I wouldn't necessarily call them "more complicated" as I would call them more difficult to solder the very close pins without shorting to adjacent pins.

I believe that all the connectors in the references I cited are the metal variety.
The plastic connectors are considerably less expensive.

Thanks to Gearslutz and Google, I found the following solutions so I'm on the right path.

Pricey but totally the type of stuff I was looking for as we are planning on getting a console and will need to do have wiring connecting various sections of the studio and there will be multiple patch bays/XLR jack bays to allow maximum flexibility.

Love the military style round connectors - they seem like they are a very strong, stable connector.

Plus they are using Klotz cables which are quite stellar.
