1U 1/4"-mini patch panel for MOTM?

Author 1U 1/4"-mini patch panel for MOTM?
sourceofuncertainty
Hi all,

Does anyone know if there's such thing as a MOTM-format 1U patch panel for swapping 1/4" and 1/8" (aka 3.5mm or mini) plugs?

Synthesizers.com has their Q122 panel, which is the right idea. But unless I'm mistaken I can't mount that to a MOTM rack rail due to the hole placement. At least not without drilling and tapping, and getting the hole exactly right. Someone please correct me if I'm wrong about that.

So if that's correct, does anyone make a 1U MOTM equivalent? Basically the left half of a MOTM-940 patch panel?

You'd definitely have to do surgery to get a Q122 in an MOTM rack.

I'm not aware of any 1U MOTM modules for this, or at least none that are pre-made.

But it should be really easy to DIY one, or have someone build one for you - someone may even have an FPD file for the panel.

Where are you located?

Ages ago there was a MOTM format jumbler kind of thing, but it disappeared. It would be dead simple to DIY however.

That's the MOTM-940 that the OP references, but it is 2U. Still available from Synthcube.

Interesting Rex,

Are you normalizing connections in the back and treating it like a mini-patchbay?

Just wondering - why not just use 1/4" to 3.5mm cables?

Lowgain elecctronics makes some stand alone boxes in various sizes and configs. He could also likely make you a MOTM panel one too.

And as others have said making your own panel or box is relatively simple if you have a decent drill and bits. SynthCube has blank MOTM panels:

LMNTL make several lengths, reasonable price, decent quality.

Yes. Here's a couple of back panel shots. I took it apart to completely reconfigure things using those 2x8 terminal strips behind each half of the cabinet. The first 3 pictures are of the prototyping phase, the last two are the finished set up. The prototype was standard steel hardware (the studs that the aluminum angle is mounted to). The finished version is all stainless steel ... every nut, bolt, washer. The mounting rails are aluminum.

The conversion panel will now be mounted on the back of the cabinet, but it will be reconfigured. I've already set up the rear of the cabinet to accept MU panels, for now they're all blanks (bottom most picture).

Only problem, Mr. Rex Coil 77777, is that the OP is asking about MOTM, which is a different size panel. Otherwise your suggestions are valid!
sourceofuncertainty
Thanks for all the responses - there's some very helpful info.

To answer some of the Qs:

- I actually do have the MOTM 940 patch panel but it's 2U and I need to get something in 1U of space since that's all I have left in my downsized 5U setup.

- Special cables would certainly work but since I've moved most of my modular setup to 1/8" I'd rather not have to keep a different set of cables at hand for the times when I need to move a signal between the two formats. I use adapters now and that's a passable option but not optimal.

- I agree it's DIYable, I was just hoping to avoid that if there's a commercial product already available. My metalsmithing skills suck. I'm that guy who can't drill a straight hole in metal even if I take all day lining it up. So I could build that but if I'm honest it'll end up really wonky, and then it's going to bother me forever.

- What Rex has there is precisely what I'm after. It's too bad Synthtech never offered a slimmer patch panel.

- I'll look into Lowgain, thanks for the tip there!

I thought that was a given? The concept is easily applied to any synth format. Use a blank panel, drill some holes, mount the jacks, do any wiring needed to suit the situation. Grab cold beers.

thumbs up

So there, Mr. Quacker. ......

Is there some way to just skip to that last step?

If you can solder but don't want to/can't drill then:

1) get a bunch of these Amphenol ACJM-MVD985-2 combo jacks
http://www.amphenolaudio.com/wp-content/uploads/2015/07/55010545000110 _acjx-mvd985-x.pdf


2) get a roll of duct tape or gaffer tape and tape them all together. leaving the solder lugs exposed (or maybe glue them together, or use zip ties, etc etc)


3) solder all the needed connections and then cover the solder lugs with MOAR tape!

4) if you don't like it floating around loose get some guitar pedal board Velcro and stick it to the side of your case. hihi

JLR,

I actually thought that Amphenol jack was a April 1 joke, but I can't believe it's real! Very cool. Must be

EDIT: I actually just looked at the price. It's not "too" bad, and it solves the dreaded "PCB mounted jack height" problem pretty nicely. Great find dude!

hihi Yeah, only about $2 in small quantities! thumbs up I bought a few of them a year or two ago for a project but ended up only using one of them for something else. So far it as worked fine.

Wow - nice find! I had no idea that existed either.

That's also very helpful - thanks for sharing.

Too bad Grayscale is out of stock on the panels, but hopefully they'll make more or someone else will create a similar design.

I'd email Grayscale and ask if they plan to make more.
They've been known to provide a FPD file for some out-of-print designs that they don't plan to reprint, so you can make it yourself.

Well I'll be dipped ... would ya look at that. 'Bout time!!

thumbs up thumbs up

If you want I could whip up a motm panel in front panel express for this in about 15 minutes. The actual panel would cost somewhere in the neighborhood of 30-40 dollars I'd guess.

I'm not sure those dual jacks would work - that 3.5mm side looks awfully short, and motm panels are 3mm thick.
boothnavy
I make one.
