I haven’t used it personally but this diy ferrite di box looks interesting:

It uses cinemag transformer.

Oh, neat!

Aside: this is actually nice to reference for folks who whinge about the price of the RIP — notice that the cinemag transformer option runs at $149, and you’d need two!

The original FE DI Box by DIYRecEq’t was one of the main inspirations for RIP. They sound great and are dead simple to use & build. Plus the transformers are ~$50 while many other options go even higher.

Did a little trial and error at the time, and liked the Cinemags / Jensens the best (they’re identical, but Cinemag designed it & is a much smaller company) for the price. Obviously form-factor was a big consideration to fit into eurorack, and availability in small quantities (only ever ordered 50 at a time, unlike real DI manufacturers orderings hundreds / thousands).

Transformers are expensive! RIP is the most expensive module we manufacture, (hint: we don’t make any money by selling them).

JDI boxes are AC coupled, so if you want to do the DC offset trick as described on the RIP page, you’ll have to go with a different box or DIY.

in response the the muff post about difference, it is mostly apparent at level of operation. transformers you can push harder and get a softer onset of harmonic distortion that is not as apparent in solid state circuits.

Thanks for the added background. The DI box kit looks like a great playground.

And cheers for your generosity!

Out of curiosity, did you ever consider adding output attenuators? I’ve found that when I really want to drive transformers for color I need to attenuate (or pad) on the way to my interface (which is easily overwhelmed).

Great point. I’ve never been able to try this and it sounds super intriguing!

:beers:

Honestly I never thought of this. My soundcard has optional pads on the first 4 inputs so I didn’t really think it necessary. In my experience you’d have to be sending a ~20V p-p signal to RIP before substantially clipping a +4dB line input (I always thought the output of RIP was a bit low ~0dB for a standard 10V p-p signal).

Why not charge more?

Simply put, they wouldn’t sell! It’s already a niche product seen as ‘too expensive’. We’ve sold 40 units in about a year and a half. It’s clearly not a ‘marketable product’ in the traditional sense, hence ‘passion project’ which doesn’t have a need to turn a profit.

Make that 41. Just ordered! :smile:

Seriously, from where I sit, this seems like a bargain. But yeah, the market is fickle… Anyway, happy to support the cause and really looking forward!

Incidentally, for folks following along and wanting to geek on some transformer physics, someone pointed me to this old muffs thread. Good stuff.

#17

I think I said the same thing a few months ago.

It just doesn’t have a hundred knobs, pressure plates, fancy Blinky lights, so people who are uninformed or don’t understand things think it ain’t shit.

Sorry I haven’t been able to really participate with more help; hopelessly overwhelmed these last few days.

I haven’t installed mine yet so I can’t say how it’s actually sounding in front of a sound card. I’ll try to report back when I do…but you’ve ordered one too. Yay!

RIP for President! (rescinding my earlier call for Cold Mac for President).

Finally unwrapped it this morning. Snapped this.

Hot! :fire:

I panicked for a second thinking it may be too deep for my case but I see it listed on modulargrid at 39mm so phew.

PS: love seeing your protest sign in the background. Headed to the airport?

#20

Oh, no; well, yes, but yesterday. Was there for about 7 hours; protesting, and helping the lawyers, bringing water, food, etc.

My son (8) actually made the sign for me, with help from his mom. On the other half he wrote about his grandmother (my mom) being a refugee, his mom being an immigrant, etc. He was stoked to try to do his part and honor the principle of it all.

Thanks for noticing! :grinning:

People may also want to look into pedalpunk di pedal. It’s originally designed to run audio through guitar/bass pedals but you can just do a loopback and warm up your audio. I also typically run stuff through a wa76 which has a cinemag trafo that makes everything sound better :slight_smile:

Looking to build a nice Modular to line converter in the style of RIP.

What schematics/ DIY kits / other things should I be looking at?

just needs 2x ins and 2x outs, but not sure about the stepping down of 10V signals to line…

I dont need a DI box, but modular levels to balanced line would be a bonus.

#24

Moving from overdrive thread here.

Iam planing sth like that too, did some research and some transformers are really easy to wire. As i have no sum/out in my skiff i want to do a little 4hp box with probably 2 1:1 transformers

Thought about my use case and figured the best for me would be to lead multiple ins (probbaly 3) to a single trafo, then the sum of it to the second trafo with an attenuator between or after 2nd.

Question: can i actualy put the load of 3 modular level (could attenuate bf) into one transformer by having multiple leads to the same pin?
Or would that overload heavily?

I am going for a mojo one 500:500 probably so i dont mind driving it, but want ofc good sound and not always distortion.
@Galapagoose might you know if that would work?

#25

I ended up ordering one of these…

got some nice ex-BBC attenuates to put to it, for stepped output.

Uh
While being from the guys country and this being tempting…it says shop closed down. You know anyT about that?

I dont see a word about wich transformer is used

But i am more tempted to go the simpler passive route. I dont feel too well soldering pcbs (opamp)

I suppose yours is electrically balanced. No trafo in there

#27

I ordered direct from Patrick…

no transformer in the build… as OP amps are used to scale…

but from what I can tell the passive route is easier, but I figured a balanced out would be worth the extra work.
