igene...As my ole man would say....

"That's slicker than owl shit"

Is this an alternative to the AKG B.I.G. cable upgrade?

I realized those cable parts are impossible to find, so I started designing a more practical application.
I took my spare CK-91 capsule apart, and stared at the parts for a long time.
I tried 4 different ideas before I got to this point.

Anyway, If this works out as well as I think it will, I've just permanently freed
the CK caps from the SE300 bodies.
I think the connector extension would fit into an Audix SMT-micro shock mount.
Have not done a fitting yet, I sold mine.

BTW - this mod takes a while to do.
One extension takes 45min to an hour to make (start to finish) before I start any other work.

Maybe this can be called the AKG B.I.G. free capsules
?


(I moved this to it's own post. I need to get an answer on the pins so I can complete the mod)

I need the contact's ID'ed inside a CK series capsule (Blueline).
Anyone who has done the hardwire version would know this.
I've been working on a capsule only mod that makes the CK91, 93 caps disconnect (and look like) the CK-1X caps...
Please help me ID the (+) contact.
thanks.
This is what I have so far >



The mod is in proto-version 1.5 now, and it looks amazing.
There were a lot of problems that needed to be solved along the way for this to work.
I think I'm almost done, I just need to solder it up and make small adjustments
I only have a dummied up prototype, but it looks great.
Now I need the wiring info, so I can test function.

ok, here's a peek...




That's damn sweet!

how much space would be needed inside the collette to house the FET et. al?

thinking length here for an answer since the inside diameter of the collette would be around 17 mm at least.

Jon, have you given any thought to making the finished capsule assembly work with any of the existing for example Delrin "stereo mounting bars" that are out there? That'll be the next thing that a lot of people will want to have after buying the "active cables."

Reality is merely an illusion, albeit a very persistent one.

Schoeps uses a fair bit of custom plastic to anchor the cable.  Using the nanocon solves a lot of the engineering and manufacturing issues.  It is an inexpensive off the shelf part for one of the trickiest bits, keeping the cost down.  That part can be standardized across different capsule colettes.  I like it.

It'd be kind of neat to solder extension pins into the nanocon solder cups, and then have those protrude through the pcb (or maybe just sit in cups on the underside).  Though if they directly coupled to the pcb, cable strain on the pins might fatigue the connections over time.  So maybe that wouldn't work.  Maybe if the pins were thin enough to flex, or allowed to float?

The downside of the nanocon is the length of the plug in connector beyond the colette.  Looks like it adds 0.9", plus any strain relief boot.   That will bring the overall to about 1.9", plus capsule.  I'm guessing that's comparable to the Lemo schoeps, but it has been quite a while since I've measured.

The portion of a Schoeps KC5 that extends outside the capsule is 5/8", plus 1/4" of neck for mounting the colette and strain relief.  So about 7/8, or 22mm, overall.  In some tight installations, that will be a challenge.  Who will be the first to make a "stubbie nanocon", potted in epoxy, possibly with a right angle exit? :P

Stereo bars would be awesome or at least mount with standard clips such as a Schoeps SGC Swivel Miniature Stand Mount or Audix MC-MICRO





Looking at the Nanocon...going to be TAO KY or MBHO territory

I wouldn't be crazy about using the nanocon as a mount because they are so tiny vs. the weight of the capsule + coupling.  I can trim the OD of the coupling after the first 9mm down from 21mm to 18mm, if that is easier than 21mm (which would fit a mic clip).

Doh...I guess the vision I had was like the Schoeps Collette/CCM have a section to clip at the back...but with the Nanocon that would not be the case...got it....

KISS would be my principle...keep it 21mm and clip to the Collette there....there are lots of microphones @ 21mm diameter

I would make a set specifically for this setup if there was enough demand. NOS, DIN, ORTF

why are "kwon" bars so costly?
seems like they should be cheap and easy to make but what do i know
Mics - AKG ck61/ck63 (c480b & Naiant actives), SP-BMC-2
XLR Cables - Silver Path w/Darktrain stubbies
Interconnect Cables - Dogstar (XLR), Darktrain (RCA > 1/8) (1/8 > 1/8), and Kind Kables (1/8f > 1/4)
Preamps - Naiant Littlebox & Tinybox
Recorders - PCM-M10 & DR-60D
