Jecklin Disc

I am thinking about building a Jecklin disc using my Soundman electrets as mics. I am gathering info on the Jecklin disc and am wondering if anyone here has experience with one. They seem to be the cat's meow for recording sound and getting the depth and ambience. So, who out there has fiddled with these Swiss wonders? B)

I've been comparing various kinds of mic placement (for omnidirectional mics like yours) a while ago including two differently sized jecklin disks - the thread is here. I've done the recordings in a rather small living room, recording music from loudspeakers.

GM - I get nothing when I go to the address for the samples: http://forums.minidisc.org/gallery/1122160...3_60_376359.mp3.

OK, Herr Jecklin specifies a 35cm disc and 36cm between mics. Further reading says the mics should be about 8 mm up from the horizontal center line. I am not sure Jecklin said this about the 8mm, who knows? I will try it with and without. If I get this damned thing to work I will post the construction process. I have an easy one. When I get it done I will test it with live music, some of which I have posted already so we can compare the ECM-MS957 against the Soundman (ist immer Deutscher besser!) and I am sure Soundman will come out ahead because it is a good mic and the Jecklin disc will enhance it. The Soundman works well for binaural when in the ears.

I will try and see what I can do to hear your samples. I just get a "done" when I go to the page. Something is wrong.

Thanks for the info. I am glad someone else is tinkering with this. What ever came out of you testing? Have you gone into the field with the disc and gotten some recordings??

Dunno, the samples work at my end (using firefox with quicktime for in-browser mp3 playback), not sure if they're donloadable, maybe try a different browser. I am quite satisfied with the hrtf placement (with the mics close, but not in your ears, directed forwards) and used that most of the time. If we had places with an open tapers section, i might be tempted to experiment with a jecklin disk or dummy head or cardioids in DIN config.

You may find this site interesting, describing microphone techniques.

By the way, i guess you know about the tapers section? Lots of info regarding mics, techniques, jecklin disks there.

GM -

I have been to the Taperssection a few times. They sneer at minidisc recorders despite the fact that they are pretty damned good, especially the sweet RH1 in PCM. They also pooh-pooh SONY mics. They seem to be in love with certain brands. Their choice. I have had mixed results over there. DPA is nice, but I get a lust for their hardware when I am there too long. ;o) I think they used to be B&K. Neuman, B&K, Telefunken, Schoeps: it all seems to be from the same area if you want really good sound. And it has been that way now for almost 70 years. Audio-Technica is pretty good, too, at a cheaper price. But first I will try the j-disc with the Soundman electrets and see how it works. I have all the materials now for the j-disc and will photograph the assembly for the other garage/home-brew geeks on the board so they can have fun with it, too.

Cheers. B)

GM, et al - OK, went to TS and got a good thread and some feedback from a fellow there. I have built the Jecklin in about a half hour. I have taken photos and will post them. I need only now to cut the faux lambs wool and attach the two pieces to cover the foam covered disc. I will post the photos with some dialog for those who need written help. It is dead easy.

I will also record some stuff at the same venues I have recorded with the SONY ECM-MS957 so we can all compare sounds.

Cheers B)
