Topic: Neumann KK 14 Miniature Clip Mic System

[mountainhop]

holy moly these are tiny tiny. same size as the mics on my pcm-a10. MK4 for reference



now to attempt to measure those threads

[jbell]

Have you had a chance to use them at a show?

they literally arrived an hour ago. havent even figured out how i am going to mount and connect to them. leery to spend an additional $400 on the goosenecks to cut up

[Popmarter]

cool, please more pics and whats up with the goosenecks?

[Popmarter]

is there a way to strip the cable out of the gooseneck and use it as a regular cable with XLR?

[mountainhop]

cool, please more pics...

here ya go. i think i got the threads sized but not 100%. need to bug my machinist buddy, the plug and ring gauges to measure those threads arent cheap

note how it is similar size to a TBxM mini xlr



can you imagine a pen-sized body with a TB3M mini-xlr in the back? would be the size of one of those keychain maglights and useful for open taping

...and whats up with the goosenecks?

is there a way to strip the cable out of the gooseneck and use it as a regular cable with XLR?

whats up with the goosenecks is they are really expensive for what they do. not only are they $199 a pop they come with a proprietary coax connector which necessitates another cable. $39 for AC31 locking minijack, $99 for AC32 lemo, $89 for AC33 microdot,  $69 for AC34 4pin mini XLR

to get them to XLR/phantom you need the $109 MCM100 output stage which is similar to the DPA DAD6001 except it is locking minijack instead of microdot. i imagine the standard dpa (or chinese knockoffs) would work with the neumann microdot cables

but using factory components with no hacks, per channel, after $299 for the capsule, you're looking at $350 for the rest ($199 gooseneck+ $39 AC31 + $109 phantom adapter)

im going to grab a gooseneck and an AC31 for testing purposes and will eat restock on them. i need to put a meter to the gooseneck and make sure it is passive. its tiny and i suppose there could be an FET in there but not sure. Apart from that i know the voltage requirements from the specs and will try the various 2-wire interfaces i have. once i know i can power the cap its just a matter of machining male ends that are cheaper and smaller than the goosenecks. i need to source a 1mm spring pin contact like the goosenecks use

Thanks, which you all the best figuring this out. Following this close.

Same, this looks nice.

Wow.  Suddenly a whole new world is opening up ...
Electret capsules should be able to power from a battery box .. or plug in power.

per the limited specs we have they want 5-10V

Maximum SPL   153 dB SPL, with Supply = 10 V, Rfeed = 20 Kilohms, for THD < 0.5%
143 dB SPL, with Supply = 5 V, Rfeed = 8.25 Kilohms, for THD < 0.5%

ill test them with as many devices as i can. looking like a homemade battery box would want the current limiting resistors to be 10-15K ohms for a typical 9V battery

It would be cool if the Microdot cables worked with a d vice or mma 6000

yeah it would

will certainly be testing that tomorrow but i have to do it on the bench with a microdot pigtail, alligator clips, and an AC31 cable, as the AC33 microdot cable is not available yet anywhere.

electrically it should be the same. hopefully the KK14 has the right impedance to turn the d:vice on, unlike line-in hacks which need a resistor to fool the d:vice into turning on

I'm very curious about how these will perform at any kind of distance.

The frequency graph https://en-de.neumann.com/kk-14#technical-data shows linear response at 15cm distance down to 20hz but the "farfield" response shows significant roll off starting at 350hz and down to -20dB at 20hz.

This is what you want to limit proximity effect when you are close miking an instrument but not necessarily what you want when you are more than a few feet away from the source.
