Jecklin Disk for Omni Stereo

[@D0n0t_Disturb]

Thank you for your no bull, no fluff video. It took me many days of searching to find quality like this.

Great, straight-forward video. Thanks. There was better separation with the J-disk at the end and sounded much more stereo to my ears.

[@homebrewedmusic]

I think I've gotten some of my best clips using the J Disk - I should get busy and build a new one with the later larger dimensions. Fran

[@jackmontreal1]

I want to sincerely congrats you for the very high quality of the content, and the recording sound and your charisma with calm atmosphere. That said, to me the difference (with headphones) is not that much between the 2! Is the 2 layer of foam are stick to a ring or if the disk is full under the foam? Bravo from Montreal Qc.

[@franguidry]

Thanks for stopping by. The disk is a solid and fairly thick piece of high impact plastic with foam stuck to it on each side. The big difference I notice when listening with headphones is the additional bass response of the omni mics. There are fundamental differences in the low end response of omni mics vs any directional mic, it's inherent in the physics. So the J Disk is an attempt to improve the stereo image when using omni mics. Fran

[@zengchristi5381]

finally, finding a video about baffle stereo! thank you!

[@homebrewedmusic]

Glad to hear you found something in the channel useful. Good luck with your recordings. Fran

[@mareaumusic]

Beautiful rich sound, even fuller than with ortf. Thanks for this video!

[@homebrewedmusic]

I really like some of the recordings I've done with the J Disk. Glad you enjoyed the demo. Fran

[@skakdosmer]

I just received the Haun Jecklin Disk and wanted some information on how to use it properly, so this video was exactly what I needed, thank you very much! I wasn't aware that you're supposed to use omnis. I have some, but nonetheless I think I'll also do a little experimentation with cardioids. Very nice that you included audio samples with ORTF also! Except for the fact that I thought the ORTF sounded much better, so I'm beginning to wonder if I might have wasted my money buying the disk. But of course it's far too soon for me to pass final judgment. But thanks again!

[@homebrewedmusic]

Sorry my samples made your choice harder, I hope you find a good use for your J disk. Fran

[@richardsisk1770]

Thanks, interesting! I appreciate to fact you have not added a goofy light in the background!

[@homebrewedmusic]

My production values are pretty low I guess (grin). Thanks for visiting. Fran

[@digitalchris6681]

Excellent video. And now I’m sold on the J method.

[@panomaniac5399]

Came to hear a Jecklin demo - got slack key guitar! Mahalo. Good clean demo. Over headphones the difference isn't huge, but noticeable.

[@homebrewedmusic]

You're certainly welcome, thanks for visiting and commenting. Fran

That was exactly what i was looking for! Thank you so much for that video

[@homebrewedmusic]

Glad the video is useful, have fun with your recording. Fran

[@LoffysDomain]

Great video, thx for sharing. 2:04 yes, ur right, higher frequencies carry less energy and die off quicker. Excellent playing, nice tone, and touch!

[@homebrewedmusic]

Thanks for visiting and for your kind comments. Fran

[@tailehuynhphat9570]

Wait, i thought higher frequencies carry more energy? That's why 5g is faster than 4g right? You meant higher frequencies gets absorbed more than lower frequencies?

[@perrycalabrese3475]

Nice video. I've been using a DIY J-disk for years to record large ensembles (wind symphonies and orchestras) with AT-4022's and CAD E70's (omni capsules). Seems like the majority of listeners use headphones these days that makes the J-disk an excellent choice for stereo imaging.

[@homebrewedmusic]

Thanks for stopping by and commenting. I just got a pair of AT 4022s myself, I'll have to try them with my home-brewed disc. Fran

[@danielgrenier2417]

How does this compare to the mid-side recording method in terms of stereo image quality?

[@MrMercho4416]

Thanks , Very useful and keep on Smiling

[@homebrewedmusic]

Thanks for taking a moment to comment. It's easy for me to keep smiling because I only do all this stuff for fun. Fran

[@WeeWillyWeiner]

Fantastic, thanks for sharing! I never get round to posting on youtube, been meaning to do some comparisons if my modded rode nt1a's with new capsules and my DIY ribbons. Keep up the good work

[@homebrewedmusic]

Sounds like you have fun with your mics. Thanks for visiting. Fran

[@Flitzefeuersocke]

Didn't know about the JDisk, but I don't really hear a difference in location btw JDisk and ORTF in this setup. The JDisk sounds a bit richer due to Omnis rrom pick up though

[@benpatterson9249]

This is great! Thanks so much for the video. I'm making a disk myself. Is it essential to be able to rotate the disc? Could I achieve the same results by moving the mic stand itself to create different relationships between the mics and the disc for tonal balance?

[@homebrewedmusic]

No need for the rotating disc at all as far as I can tell. The latest version of the disc spec calls for a larger disc and I found an article that suggests using rockwool for the disk material. I think I'm going to build one of these myself: gearspace.com/board/remote-possibilities-in-location-recording-amp-production/1056249-jecklin-disk-revisited-diy.html And this Wikipedia article has a slightly different spec: en.wikipedia.org/wiki/Jecklin_disk Fran

[@lesagogo1428]

Amazing video .. I wonder if that same jecklin disk technique along with the KSM141 would be useful for sound landscapes. I think this because of its omnidirectional characteristic.

[@homebrewedmusic]

I think you might be right, it would be interesting to try. And there are many excellent omni microphones that are not terribly expensive. Fran

[@halukkurtoglu126]

[@hervebizot785]

Merci beaucoup . Would you consider Jecklin disc configuration ( or Ortf ) as a good option for recording piano voice casting clips for lyric singers? Would you suggest an alternative such as simply use a H6 ( or lower). Any related URL to consult? Enjoy strings.

[@jweatherly26]

I know I'm replying 3 months late and you probably arent looking for an answer any more. In my ameture opinion, ORTF and XY pattern produce a cleaner recording of a single instrament, where as a J-disk would be ideal for recording a concert/the whole band from a single point.

[@WeeWillyWeiner]

Fantastic, thanks for sharing!

[@forlecture6507]

J Disk's frequency dependent correlation coefficient is less correlated so spatial impression would be better than ORTF.

[@MrHamit64]

So what omni mics can 1 use with these disks? For example can I use AT-4022 mics? or do they have to be the little clip on mics? I just got to the part of the vid where you said you're using KSM140s. How big are those? I'm blind.

[@homebrewedmusic]

A pair of AT4022s would be exemplary mics for use with a Jecklin Disk. Shure KSM144s are about the same size as the AT4022, I think. Fran

[@blipblip100]

Very interesting - Thanks

[@homebrewedmusic]

The gentleman who invented this technique passed away recently but his gadget lives on! Fran

[@michaelbennett9127]

You seem like such a decent guy! Thanks for this. I'd imagine that a piece (or two) of acoustic foam would be a cheaper option. I'm not sure I'm entirely convinced that this adaptation makes a difference with, compared to without. I haven't seen this in videos of top studios, although, this seems specific omni polar patterns, and I have no personal reference, as I generally use a cardioid polar pattern

[@homebrewedmusic]

Thaks for visiting and commenting. Simple acoustic foam won't give the same result as a solid disk. It's certainly possible to cobble together a working Jdisk without spending for a commercial disk, though. Perhaps the best thing about this commercial disk is the mic mounting arrangement. The OSS or Jecklin disk technique was developed by an engineer/professor who works with classical music in concert halls. It's not usually used in studio recordings. Of course studio recordings tend to be multi-miked, while the purpose of the Jdisk is intended to be a single main pair that captures an entire ensemble. The Jecklin Disk is indeed designed around omni mics. Omnis have a fundamentally different response to low frequencies compared to directional mics. Spaced omnis are another technique often used for recording classical ensembles, giving a more enveloping sense of space and more accurate low frequencies while sacrificing precise location and mono compatibility. The Jdisk is intended to give more detailed location and mono compatibility while maintaining the benefits of the omni pattern. My use of the Jdisk is out of the norm since I'm recording a single instrument with a close mic distance, but I have made some of my most satisfying recordings using this technique. I also "break the rules" and use ORTF spaced cardioids for some of my solo guitar recordings, but I like the wider soundfield of the spaced pair over the tighter sound of an XY array. Fran

[@menriquez89]

Thanks for this info! In your opinion, would this be a good method for recording a young student’s drum circle outside on the grass at a park? I have ksm 141’s. We’ll be set up in a semi circle with 6 feet between each student. I’ll be at the focal point of the circle. Do you think I should place the mics in the middle of the circle, or above and behind me? Any thoughts would be much appreciated

[@homebrewedmusic]

My first thought would be to use the KSM141s in a spaced array. ORTF is a good model: en.wikipedia.org/wiki/ORTF_stereo_technique I would place this array near the center of the semi-circle, perhaps back a bit. Hopefully you'll have a chance to test some mic configurations?? If I were you I would try to do a quick recording in ORTF then switch the KSM141s to Omni and space them about 16" and moved in closer than the center of the semi-circle. Then listen to the results and choose the better one for your final recording. Fran

[@menriquez89]

homebrewedmusic thank you! I won’t have lots of time because I’ll be instructing, playing, and recording. But I think I’ll be able to try at least two configurations. Your videos were helpful! I also decided to get a zoom f8 based on your explanation of the 32 bit float technology. Appreciate it!

[@homebrewedmusic]

@@menriquez89 Good luck with your recording project. I'm not sure how my explanation helped you choose the F8 - the F8 does not offer 32 bit float, so far the only Zoom recorder with that tech is the F6. Fran

[@oli77sch]

Personally I prefer the Jecklin Disc over the ORTF here, and these Shure mics sound great.

[@homebrewedmusic]

Thanks for taking a moment to offer your comment. I love using omni mics to record acoustic guitar, and the Jdisk adds a nice bit of separation for a more interesting audio image. Fran

[@danshouse]

@@homebrewedmusic got some new small diaphragm condensers and want to try their omni capsules with the jecklin disc.

[@homebrewedmusic]

@@danshouse Commercial J-disks can be a bit expensive but it's not too hard to come up with something that works if you have a couple of mic stands to position the mics. It only gets really complicated if you try to integrate the mic holders with the disk. Fran

[@danshouse]

@@homebrewedmusic Built a quickie disc with plywood and felt! Will try it out...

[@blankpool]

Will this work with a panel room divider instead of a disk?

[@nagirano6325]

hi what about the spacing between two mics? It looks on the video that the space is 16,5 not the second 'improved' twice as big version, that is mentioned in wikipedia am I correct? My idea is to use 16,5cm spacing that is already in place in my tascam recorded - tascam dp 008, and to mimic Jecklin disk idea approach I would make a dividing disk that would be attached to the recorder, what do you think?Best Regards M

[@homebrewedmusic]

You're right, this demo uses the smaller spacing. The larger spacing is used with a larger disk as I recall and the mic mounts on my disk would make it hard to achieve the wider spacing. I think your idea of using a disk with your recorder sounds excellent. Fran

[@nagirano6325]

@@homebrewedmusic thank you, yes I was actually going to ask further if you have any comperisement with the wider option and if its a significant improvement, it wouldnt deter my willingness to do the project but i'm just curious, cheers!!

[@portaismusicstudio]

very nice .... thanks

[@homebrewedmusic]

Thanks for taking a moment to comment. Fran

[@duuster-audio]

Nice. Too bad you had no XY instead of ortf at that distance, to have a more centered sound. I love ortf for immersive soundscapes, nature recording, but prefer XY for closer sound sources. A comparison between Jecklin disk and regular AB for the omni's would also be great, but you can't do it all at once ;-) Thanks for sharing.

[@homebrewedmusic]

That comparison of J disk vs AB would be an excellent comparison. I sold off my disk because I'm understanding that Jecklin revised the specs to use a larger disk and wider spacing, but I haven't gotten around to constructing the new disk. Fran
