PreenFM2 / Re: Mystery part

Thanks for the great info!

What do I do with the wire on the shield? Where should it connect to?

yes, this is used to keep aliens from your preenfm. just put it over the display, so they cannot read your secret patches :-)

no seriously, this is a shield that belongs between the display and the pcb, to reduce the high frequency noise that the oled display emits. see here: http://ixox.fr/forum/index.php?topic=69159.0

That looks like a ready-made shield to avoid the OLED high frequency parasite problem.
You can read about it here.

PreenFM2 / Mystery part

I assembled my Preen2FM tonight and everything went great. However, included in my kit was THIS PART that I couldn't find on the BOM or anywhere in the instructions. Any idea what this is supposed to be used for? Did I miss something?

If you are monitoring through a DAW you may use an EQ around 15.5 kHz with a really narrow bandwidth, that will work and should be quite discreet.

Hi! I bought a Preenfm2 from Van Daal. I'm really loving it, but I hear the "OLED noise" and since I don't know anything about soldering and DIY I was wondering if there is a way to delete that freq without affecting the timbre of my patches... may I use an eq? could be enough?

Great, thanks for that info - very helpful!
Not 100% clear on some things you describe but hopefully i will work it out when i get there. It´s always good to have some inside info though, before getting started.

Thanks for the video reminder, i´d totally forgot about that one!  :D

Can someone please post a sideways picture of their PreenFM2? Like the one I've posted above.

Hi.

Replay from Van Daal :)

That Red Wima is 1n. They should be the best you can get at that price.
You should also Pay attention to the Screen Shield.
MIDI cabling/connector is different.
Pin headers, place only what you actually need. There is not enough to solder all the pinheaders, because you dont need them.
Look through the video posted under Van Daal shop DIY kit page.

Good luck!

Thank you Xavier for your swift reply and explanation, i feel a lot more confident now.  :)
I have sent a question to Van Daal as well, and will update the thread with their response, to add to the general knowledge base.
